TY - JOUR T1 - CO sub(2)/brine/rock interactions in Lower Tuscaloosa formation AN - 1855084788; PQ0003949659 AB - Saline aquifers are the largest potential continental geologic CO sub(2) sequestration resource. Understanding of potential geochemically induced changes to the porosity and permeability of host CO sub(2) storage and sealing formation rock will improve our ability to predict CO sub(2) plume dynamics, storage capacity, and long-term reservoir behavior. Experiments exploring geochemical interactions of CO sub(2)/brine/rock on saline formations under CO sub(2) sequestration conditions were conducted in a static system. Chemical interactions in core samples from the Lower Tuscaloosa formation from Jackson County, Mississippi, with exposure to CO sub(2)-saturated brine under sequestration conditions were studied through six months of batch exposure. The experimental conditions to which the core samples of Lower Tuscaloosa sandstone and Selma chalk were exposed to a temperature of 85 degree C, CO sub(2) pressure of 23.8 MPa (3500 psig), while immersed in a model brine representative of Tuscaloosa Basin. Computed tomography (CT), X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM), brine chemistry, and petrography analyses were performed before and after the exposure. Permeability measurements from the sandstone core sample before and after exposure showed a permeability reduction. No significant change of the permeability measurements was noticed for the core sample obtained from Selma chalk after it was exposed to CO sub(2)/brine for six months. These results have implications for performance of the storage interval, and the integrity of the seal in a CO sub(2) storage setting.

N1 - Last updated - 2016-11-16 ER - TY - JOUR T1 - Mathematical modeling of a moving bed reactor for post-combustion CO sub(2) capture AN - 1827881715; PQ0003725858 AB - A mathematical model for a moving bed reactor with embedded heat exchanger has been developed for application to solid sorbent-based capture of carbon dioxide from flue gas emitted by coal-fired power plants. The reactor model is one-dimensional, non-isothermal, and pressure-driven. The two-phase (gas and solids) model includes rigorous kinetics and heat and mass transfer between the two phases. Flow characteristics of the gas and solids in the moving bed are obtained by analogy with correlations for fixed and fluidized bed systems. From the steady-state perspective, this work presents the impact of key design variables that can be used for optimization. From the dynamic perspective, the article shows transient profiles of key outputs that should be taken into account while designing an effective control system. In addition, the article also presents performance of a model predictive controller for the moving bed regenerator under process constraints. copyright 2016 American Institute of Chemical Engineers AIChE J, 62: 3899-3914, 2016 JF - AICHE Journal AU - Kim, Hosoo AU - Miller, David C AU - Modekurti, Srinivasarao AU - Omell, Benjamin AU - Bhattacharyya, Debangsu AU - Zitney, Stephen E AD - National Energy Technology Laboratory, 3610 Collins Ferry Road, Morgantown, WV, 26507.

Microbial community change in these subsurface sites may affect injectivity of CO2, permanence of stored CO2, and shallow subsurface water quality. The effect of CO2 concentration on the microbial communities in fluid collected from a depleted oil reservoir and a freshwater aquifer was examined at subsurface pressures and temperatures. The community was exposed to 0%, 1%, 10%, and 100% pCO2 for 56 days. Bacterial community structure was analyzed through 16S rRNA gene clone libraries, and total bacterial abundance was estimated through quantitative polymerase chain reaction. Changes in the microbial community observed in the depleted oil reservoir samples and freshwater samples were compared to previous results from CO2-exposed deep saline aquifer fluids. Overall, results suggest that CO2 exposure to microbial communities will result in pH-dependent population change, and the CO2-selected microbial communities will vary among sites. This is the first study to compare the response of multiple subsurface microbial communities at conditions expected during geologic carbon storage, increasing the understanding of environmental drivers for microbial community changes in CO2-exposed environments.

Proppant movement is tracked in a fractured core of Marcellus shale placed under a series of increasing confining pressures up to 10,000 psi. The analysis reveals the sudden failure of a region of the proppant pack, accompanied by the large-scale rearrangement of grains across the entire fracture surface. The failure of the pack coincides with the appearance of vortex-like grain motions similar to features observed in biaxial compression of two dimensional granular assemblies JF - International Journal of Rock Mechanics and Mining Sciences (1997) AU - Walsh, Stuart D C AU - Smith, Megan AU - Carroll, Susan A AU - Crandall, Dustin Y1 - 2016/09// PY - 2016 DA - September 2016 SP - 39 EP - 47 PB - Elsevier, Oxford-New York VL - 87 SN - 1365-1609, 1365-1609 KW - tomography KW - fractured materials KW - hydraulics KW - three-dimensional models KW - proppant KW - biaxial tests KW - shale KW - loading KW - non-invasive methods KW - deformation KW - rock mechanics KW - measurement KW - sedimentary rocks KW - compressive strength KW - confining pressure KW - clastic rocks KW - 30:Engineering geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1828846877?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=International+Journal+of+Rock+Mechanics+and+Mining+Sciences+%281997%29&rft.atitle=Non-invasive+measurement+of+proppant+pack+deformation&rft.au=Walsh%2C+Stuart+D+C%3BSmith%2C+Megan%3BCarroll%2C+Susan+A%3BCrandall%2C+Dustin&rft.aulast=Walsh&rft.aufirst=Stuart+D&rft.date=2016-09-01&rft.volume=87&rft.issue=&rft.spage=39&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Rock+Mechanics+and+Mining+Sciences+%281997%29&rft.issn=13651609&rft_id=info:doi/10.1016%2Fj.ijrmms.2016.05.005 L2 - http://www.sciencedirect.com/science/journal/13651609 LA - English DB - GeoRef N1 - Copyright - GeoRef, Copyright 2016, American Geosciences Institute.

Given a domain of 100 100 km and a formation permeability of 10 super(-13) m super(2), outer boundary condition does not have a significant impact on pressure increase and CO sub(2) saturation results. In a simulation period of 30 years of CO sub(2) injection + 100 years of post CO sub(2) injection, with a total CO sub(2) injection volume of 6.310 super(7) m super(3) at T = 47 degree C and P = 10.5 MPa (equivalent mass of 30 million tonnes of CO sub(2)), there is no pressure difference between the no flow boundary case and the open boundary case given a domain size of 100 x 100 km (a total storage formation pore volume of 10 super(11) m super(3) at T = 47 degree C and P = 10.5 MPa), and the maximum CO sub(2) plume radius difference is 0.5%. However, given a domain size of 10 10 km, outer boundary condition significantly affects pressure simulation results. At t = 130 years, the pressure increase in the no flow boundary case is 56.5 times of the pressure increase in the open boundary case at the cell 50 m away from the injection well. For the 10 10 km case, the impact of outer boundary condition on CO sub(2) saturation results is relatively small. The change in formation permeability significantly affects pressure increase results, while the change in CO sub(2) relative permeability model only affects pressure increase results at cells close to the CO sub(2) injector. copyright 2016 Society of Chemical Industry and John Wiley & Sons, Ltd JF - Greenhouse Gases: Science and Technology AU - Zhang, Liwei AU - Dilmore, Robert M AU - Bromhal, Grant S AD - National Energy Technology Laboratory, Pittsburgh, PA, USA.

The model predicted formation of a high-porosity zone adjacent to the surface of the sample in contact with bulk brine, and a lower porosity zone just beyond that high-porosity zone along the path from the sample/bulk brine interface to sample core. The formation of the high porosity zone was attributed to the dissolution of quartz and muscovite/illite, while the formation of the lower porosity zone adjacent to the high porosity zone was attributed to precipitation of kaolinite and feldspar. The model predicted a 40% permeability increase for the Knox sandstone sample after 180 days of exposure to CO sub(2)-saturated brine, which was consistent with laboratory-measured permeability results. Model-predicted solution chemistry results were also found to be consistent with laboratory-measured solution chemistry data. Initial porosity, initial feldspar content, and the exponent n value (determined by pore structure and tortuosity) used in permeability calculations were three important factors affecting permeability evolution of sandstone samples under CO sub(2) sequestration conditions.

A 3-D TOUGH2 model was used to simulate the flow of groundwater under the high hydraulic heads that may be imposed by such trapped compressed air, based on an observed case in West Virginia (USA) in 2012. The model realizations show that high-pressure air trapped in aquifers may cause groundwater to surge away from the drill site at observable velocities. If dissolved methane is present within the aquifer, the methane can be entrained and transported to a maximum distance of 10.6 m per day. Results from this study suggest that one cause of the reported increase in methane concentrations in groundwater near shale gas production wells may be the transport of pre-existing methane via groundwater surges induced by air drilling, not necessarily direct natural gas leakage from the unconventional gas reservoir.

Geomechanical properties of complex porous systems are dynamically linked to flow conditions, but their feedback relationship is often oversimplified due to the difficulty of representing pore-scale stress deformation and multiphase flow characteristics in high fidelity. In this work, we performed pore-scale experiments of single- and multiphase flow through bead packs at different confining pressure conditions to elucidate compaction-dependent characteristics of granular packs and their impact on fluid flow. A series of drainage and imbibition cycles were conducted on a water-wet, soda-lime glass bead pack under varying confining stress conditions. Simultaneously, X-ray micro-CT was used to visualize and quantify the degree of deformation and fluid distribution corresponding with each stress condition and injection cycle. Micro-CT images were segmented using a gradient-based method to identify fluids (e.g., oil and water), and solid phase redistribution throughout the different experimental stages. Changes in porosity, tortuosity, and specific surface area were quantified as a function of applied confining pressure. Results demonstrate varying degrees of sensitivity of these properties to confining pressure, which suggests that caution must be taken when considering scalability of these properties for practical modeling purposes. Changes in capillary number with confining pressure are attributed to the increase in pore velocity as a result of pore contraction. However, this increase in pore velocity was found to have a marginal impact on average phase trapping at different confining pressures. Abstract Copyright (2010), John Wiley & Sons, Ltd.

The flux and downstream evolution of dissolved inorganic carbon (DIC) is presented for two coal mine sites that discharge high concentrations of DIC (3.7-4.5 mM C) producing a total flux of DIC from the mine from 13 to 249 kg-C/year (18-364 metric tons of CO (sub 2) /year). More than 65 % of the total DIC is lost via CO (sub 2) evasion with the remaining DIC is exported downstream as dissolved species. The fate of the DIC depends upon the pH of the water which is controlled by evasion of CO (sub 2) , the concentration of pre-existing alkalinity, carbonate precipitation and dissolution, and metal hydrolysis reactions. The CO (sub 2) concentrations and fluxes from the study sites are comparable to those estimated from literature data for other coal mine sites in the Appalachian region. The total flux estimated from a dataset of 140 coal mines was comparable in magnitude to the CO (sub 2) emissions from a small coal-fired power plant. The extent of CO (sub 2) degassing from mine waters is poorly constrained because (1) flux estimates can be biased low when acid waters are excluded in alkalinity-based estimates; (2) flux estimates can be biased high if non-carbonate alkalinity is present in the mine waters; and (3) mine waters react rapidly following discharge hampering the measurement process. The study sites presented illustrate the impact of coal mining as an anthropogenic influence on carbon cycling; however, more data are necessary to fully estimate the importance of this impact on regional scales.

Gas hydrate exploration now integrates the unique pressure and temperature preconditions for gas hydrate occurrence with those concepts and practices that are the basis for conventional oil and gas exploration. We have aimed to assimilate the lessons learned to date in global gas hydrate exploration to outline a generalized prospecting approach as follows: (1) use existing well and geophysical data to delineate the gas hydrate stability zone (GHSZ), (2) identify and evaluate potential direct indications of hydrate occurrence through evaluation of interval of elevated acoustic velocity and/or seismic events of prospective amplitude and polarity, (3) mitigate geologic risk via regional seismic and stratigraphic facies analysis as well as seismic mapping of amplitude distribution along prospective horizons, and (4) mitigate further prospect risk through assessment of the evidence of gas presence and migration into the GHSZ. Although a wide range of occurrence types might ultimately become viable energy supply options, this approach, which has been tested in only a small number of locations worldwide, has directed prospect evaluation toward those sand-hosted, high-saturation occurrences that were presently considered to have the greatest future commercial potential.

Some of these shear events are measurable as micro-seismic activity, but understanding how a shear event alters initial fracture permeability is poor. When attempting to model how these measured events impact transport in the subsurface improved relationships coupling rock properties, stress state, shear displacement, and the resulting change in fracture permeability are required. This experimental work is designed to examine these relationships. A novel shearing device was created enabling simultaneous fracture shearing, computed tomography (CT) scanning, and permeability measurements of pre-fractured rock cores. Visualizing the change in the fracture geometry via CT while measuring changes in the fracture permeability allows direct isolation of the changes in fracture geometry that impact the bulk permeability changes. In addition, extraction of the fracture geometry enabled direct numerical simulations of flow. This coupling of fine-scale numerical and core-scale experimental results illustrates the impacts of flow channelization and asperity evolution on the migration of fluids in fractures. This presentation reviews the first series of experiments and simulations that were performed with these techniques; shearing of fractured Marcellus shale under various confining pressures. Results show that confining pressure influences the behavior of the sheared fractures, that channelization of fluids through the fractures increases with shearing, and that localized breakages of the fracture drastically alter the bulk fracture permeability. On-going work examining the shearing of fracture CO (sub 2) storage sealing formations will be reviewed as well.

Knowing how REE are distributed in coal ash is essential to devising extraction strategies and for developing possible approaches to pre-concentrate REE. REE-bearing trace phases are much less commonly observed in coal ash than in the corresponding coal, leading to the suggestion that REE may be partitioned into the glass phase during coal combustion at boiler temperatures. To better understand the distribution of REE in coal ash, in the present study we used the Stanford/USGS SHRIMP-RG ion microprobe to determine grain-scale REE partitioning in coal ash derived from various U.S. and international coals. Prior to SHRIMP-RG analysis, samples were characterized by backscattered electron imaging and wavelength-dispersive elemental mapping, showing constituents of the ash and their major element distributions. SHRIMP-RG microanalysis used a nominal spot size of 15 micrometers and an oxygen negative-ion primary beam. NIST multi-element glass standards SRM 611 and SRM 613 were used for REE calibration. Results confirm the occurrence of REE in aluminosilicate glasses at concentrations that span those of the respective bulk coal ash samples. Co-occurring quartz and/or high-silica glasses generally have much lower REE contents than aluminosilicate glasses, consistent with results for bulk coal ash samples showing a strong positive correlation between Al and REE content. Fe-oxide spheres were found to have variable REE contents. Results suggest that total digestion of the aluminosilicate glass fraction in coal ash will yield a significant portion of the REE present and that limited pre-concentration may be accomplished by removing the least REE-enriched fractions.

With that growing interest, the city of Pittsburgh, Pennsylvania wants to establish a sustainable residential/commercial district in which geothermal solutions will be used for direct heating/cooling. This study focuses on suitable areas in both the surface and subsurface for low grade EGS potential in and surrounding Pittsburgh in greater detail. Data from the National Geothermal Data System was used to interpolate temperature gradient and heat flow using the natural neighbor method. United States Geological Survey (USGS) and Information Handling Services (IHS) data were used to determine the thicknesses of formations. Temperature gradients in the area ranged from 13-22 degrees C/km with the target area being 19-20 degrees C/km. Heat flow ranged from 35-60 mW/m (super 2) with the target area being 46-60 mW/m (super 2) . The temperature gradient was used to create subsea depth to 80 degrees C and subsea depth to 150 degrees C maps showing a range of -3809 to -3048 m and -7619 to -6858 m respectively. Preliminary suitability analysis using normalized values of the temperature gradient and heat flow shows that the area of interest has a relatively low geothermal potential compared to the rest of the Pittsburgh vicinity. Well data reveals nearby inactive wells completed before 1962 with the nearest one to the area of interest being 656 m deep and completed in 1913. A model was used to calculate years to abandonment and monthly flow rate. For a sandstone layer 61 m thick at a depth of 3810 m, the model shows 25 years (54.4 degrees C water in, 65.6 degrees C water out) and 14 years (71.1 degrees C water in, 82.2 degrees C water out). An estimated cost for a well that has a measured depth of 5000 m is around $15-17 million.

More than 400 surface exposures and drill core samples were studied and more are being added to the data set regularly. A rigorous statistical analysis of the sample set was completed and a comparison with standard reference materials was performed. Data indicate that the rocks in this study are enriched in total rare earth elements compared to both the NASC and PAAS. Pearson correlation studies indicate that the light rare earth elements are likely concentrated in phosphate minerals and the heavy rare earth elements are correlated with iron-bearing mineral phases. A correlation of total rare earth elements with Ti/Al in stratigraphically collected samples indicates that in some sample locations high total REE contents occur in samples where depositional rates were highest. These data support the hypothesis that REE are physically weathered into the sedimentary rocks and that chemical erosion was minimal. In other sample locations, geochemical and mineralogical evidence supports aqueous remobilization of REE and critical elements. In these cases, minor deposits of adsorbed REE, similar to the ion adsorbed REE deposits of China, may have formed.

The Eastern Gas Shales Project (EGSP) was intended to help industry overcome the challenges of recovering natural gas from organic-rich, low permeability, Devonian-age shales in the eastern United States. When the U. S. Department of Energy (DOE) was created in August 1977, the EGSP became its responsibility. The EGSP characterized oriented drill core from 44 wells targeting a variety of Devonian shale formations in the Michigan, Illinois, and Appalachian Basins. The program objectives were to assess the resource, develop effective extraction technology, and transfer such knowledge to industry. The program ended in 1992. Mitchell Energy had been pursuing shale gas since the early days of the EGSP, and achieved commercial success in 1997 on the Barnett Shale in the Fort Worth Basin of Texas. Mitchell applied offshore directional drilling technology to construct long horizontal wells, and staged hydraulic fracturing to stimulate large volumes of rock. The Fayetteville Shale in Arkansas and the Haynesville Shale in Louisiana were developed a few years later using the Mitchell methods. Range Resources drilled the Renz #1 well in Pennsylvania to a Silurian target formation in 2005, which showed little gas potential. However, evidence of gas in the overlying Marcellus Shale led Range to review the EGSP data, and the well was successfully recompleted in the Marcellus. Thus encouraged, Range experimented with the Mitchell Energy horizontal drilling and hydraulic fracturing techniques on the Marcellus, eventually completing the Gulla #9 well with an initial gas production rate of nearly 142,000 cubic meters (5 MMCF) per day. Other wells soon followed, developing the play remarkably within five years. The success in the Marcellus led to the subsequent development of additional shale resources, including the Niobrara in Colorado and Wyoming, the Woodford in Oklahoma, the Utica in Ohio, and the Eagle Ford in Texas. The development of the gigantic Bakken Shale oil play in North Dakota has made it the second largest oil producing state in the U. S. after Texas. Gas and oil from shale are likely to remain important energy resources in the future.

IMS strategies are used primarily in oilfield applications, but many of their components are readily adaptable to CO (sub 2) storage projects. New and distinct IMS components are needed to address storage-specific objectives and challenges for both enhanced oil recovery (EOR) and saline CO (sub 2) storage activities. It is envisioned that an IMS system will contribute to workers safety, reservoir surveillance, well surveillance, surface process surveillance, pipeline surveillance, and real time system optimization, resulting in greater efficiency and reduced costs. IMS is a broad technology area, encompassing sensors and actuators, hardware and software tools for data acquisition, management, transmission, and software tools for modeling and visualization. The DOE Carbon Storage Program is developing an integrated IMS architecture to help commercialize carbon capture and storage (CCS) by developing high resolution, long-term or permanent systems to monitor the behavior of the CO (sub 2) in the reservoir, detect possible leakage pathways, and quantify any leakage volumes. Improved systems are needed to monitor the surface, wellbores, and the subsurface. Software tools for modeling, analysis, and integration are critical components of an IMS. The Storage Program is developing software tools such as neural networks, artificial intelligence and soft computing technologies for decision making and optimization of reservoir management. These software tools would be combined with coupled modeling codes to evaluate collected data and present the analysis in a user friendly format for decision makers. Optimization of injection operations in CO (sub 2) storage projects would include tools for decision making, closed-loop reservoir process control, detection and processing of events. A fully integrated IMS system at a commercial CCS facility should provide timely information and automate some of the routine process thus resulting in significant cost savings.

These drill cuttings are destined for landfill disposal, in-situ burial, and potential reuse as road fill. The drill cuttings resulting from the horizontal drilling into the Marcellus formation in particular contain significant amounts of fine-grained black shale rock cuttings, rich in organic matter and trace metal content. aLeaching tests were performed in order to evaluate the leachability of metals from drill cuttings under various environmental conditions, particularly from the Marcellus horizon. Understanding the geochemical characteristics of the Marcellus shale drill cuttings will assist in making waste management decisions. a Twenty-two drill cutting samples were obtained from the Marcellus Shale Energy and Environment Laboratory (MSEEL) in WV. Cuttings were collected along 320 ft intervals during horizontal drilling of a well into the Marcellus formation. These drill cuttings were analyzed for elemental composition by inductively coupled plasma-mass spectroscopy (ICP-MS), total carbon and sulfur via CHNS/O elemental analysis, and mineral phases by X-ray diffraction (XRD). Trace metal associations were mapped by micro X-ray fluorescence (mu -XRF) at Stanford Synchrotron Light Source (SSRL). Preliminary results show that cutting samples containing trace metals such as: As, U, Zn, and Cu, tend to be samples that have high organic carbon (up to 10.3 wt%) and pyrite content. Micro-XRF mapping shows 50-100mu m size U, As and Cu hotspots, mainly co-localized with small Fe grains (50-200 mu m), or distributed on larger Fe grains (0.5-2 mm). Barium content is elevated throughout all samples ( nearly equal 5 wt%) and can in part be attributed to residual drill mud. aMicro-XRF mapping reveals Ba coatings on mineral grains, which supports Ba being primarily from residual drilling muds in these samples. aLeaching tests further identify various leaching conditions influencing trace metal mobility, such as different leachate composition (simulating rainfall or landfill conditions), pH and liquid: solid ratio. Tests are designed to mimic short-term and long-term leaching tests under different conditions in order to evaluate key elements to monitor in Marcellus shale drill cutting disposal scenarios. a JF - Abstracts with Programs - Geological Society of America AU - Lopano, Christina L AU - Stuckman, Mengling AU - Y , Hakala AU - J, Alexandra AU - Anonymous Y1 - 2016 PY - 2016 DA - 2016 SP - Abstract no. 122 EP - 8 PB - Geological Society of America (GSA), Boulder, CO VL - 48 IS - 7 SN - 0016-7592, 0016-7592 UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1861108998?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefinprocess&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=Geochemical+characteristics+of+drill+cuttings+from+Marcellus+Shale+energy+development&rft.au=Lopano%2C+Christina+L%3BStuckman%2C+Mengling%3BY+%2C+Hakala%3BJ%2C+Alexandra%3BAnonymous&rft.aulast=Lopano&rft.aufirst=Christina&rft.date=2016-01-01&rft.volume=48&rft.issue=7&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2016 annual meeting & exposition N1 - Copyright - GeoRef in Process, Copyright 2017, American Geosciences Institute.

Researchers have been trying to find a way to extract rare earth elements from low REE concentrated secondary sources as a byproduct from already-existing processes such as coal mining in order to reduce waste, energy consumption, and cost. Portable XRF could be a useful tool in this process because of its ability to analyze coal and other field materials on-site, but its accuracy in reporting REE data at low concentrations has been questionable. This study will use a portable Niton XL3t GOLDD+ XRF Analyzer to analyze materials associated with coal. The focus will be the lanthanide elements and elements that are associated with REE, such as thorium and yttrium. Determining whether a portable XRF device can provide accurate data about the concentration of rare earth elements in materials associated with a coal deposit will be discussed. Optimal settings such as mode, time, and sample preparation will be studied. Different calibration methods such as method of standard additions will also be examined.

Some of these shear events are measurable as micro-seismic activity, but understanding how a shear event alters initial fracture permeability is poor. When attempting to model how these measured events impact transport in the subsurface improved relationships coupling rock properties, stress state, shear displacement, and the resulting change in fracture permeability are required. This experimental work is designed to examine these relationships. A novel shearing device was created enabling simultaneous fracture shearing, computed tomography (CT) scanning, and permeability measurements of pre-fractured rock cores. Visualizing the change in the fracture geometry via CT while measuring changes in the fracture permeability allows direct isolation of the changes in fracture geometry that impact the bulk permeability changes. In addition, extraction of the fracture geometry enabled direct numerical simulations of flow. This coupling of fine-scale numerical and core-scale experimental results illustrates the impacts of flow channelization and asperity evolution on the migration of fluids in fractures. This presentation reviews the first series of experiments and simulations that were performed with these techniques; shearing of fractured Marcellus shale under various confining pressures. Results show that confining pressure influences the behavior of the sheared fractures, that channelization of fluids through the fractures increases with shearing, and that localized breakages of the fracture drastically alter the bulk fracture permeability. On-going work examining the shearing of fracture CO2 storage sealing formations will be reviewed as well.

Such knowledge is very important for the estimation of the magnitude and orientation of the in situ stress, which are generally very difficult to estimate because of many uncertain factors, such as tectonic movement, rock heterogeneities, discontinuities, pore pressures, heat flow, etc. In comparison with many other geological settings, a stable intracratonic basin has a relatively flat structure that allows for a tractable numerical conceptualization to be made to help understand the faulting regime conditions. Some intracratonic basins such as the Williston Basin (USA), the Tarim Basin (China), and the Siberia Basin (Russia) are important sites to host oil reservoirs and may also provide the spaces for CO (sub 2) sequestration. In this paper, numerical simulation is used to characterize the Illinois Basin in North America. This paper presents the methodology for estimating the in situ stress conditions of an intracratonic basin using a poroelastic model. The numerical simulation results show that a thrust-faulting regime is expected at shallow depths, while the three principal stresses are close in magnitude at intermediate depths. A strike-faulting regime dominates at great depths, which corresponds to the continental stress pattern.

In general, the abundance of REEs produced by aqueous extraction processes is low. Additionally, most samples contain elements that interfere with the determination of REEs, so that separation and pre-concentration steps are often necessary. A number of techniques based on ion-exchange resins and solvent extraction have been studied and proposed. In the present work, the feasibility of using alginate gel for REE recovery and separation was examined. Alginic acid is a linear copolymer consisting of D-mannuronic and L-guluronic acids that forms hydrogels with many divalent cations, including Ca(II), Ba(II), Sr(II), Cu(II), Pb(II) and others. In our experiments, the gel beads were formed by dropping 2% sodium alginate directly into aqueous solutions of REEs with various mixtures of divalent cations. Modifications of solid alginate beads made by dosing with compounds capable of generating specific REE-binding ligands were also tested. We examined how specific REEs were selectively sequestered within alginate gel via gel polymerization and by further diffusion and potential displacement reactions. The data are discussed relative to improvements in the analytical quantification of low level REEs and with regard to potential applications of this technique for fast and complete recovery of REE from complex matrices.

These cold traps, which Balch termed "glacieres naturelles" or natural refrigerators, were found in ravines and gorges, taluses and boulder heaps, as well as in man-made wells, mines and tunnels from West Virginia northward into New England. Despite local reports to the contrary, no perennial ice was ever observed by Balch, although accumulated ice from the winter and spring clearly persisted for an unusually long time at sites where it was naturally or artificially protected from the sun and wind in the summer. Cold air coming from the base of talus slopes throughout the summer suggested the possible continued presence of ice deep in the talus, but this could not be confirmed. In the current study, we used temperature data loggers to monitor the thermal regime of cold traps in Pennsylvania and New York where ice exhibited unusual persistence: these sites included man-made mine shafts ("ice mines"), a talus slope, two "rock cities," and a collapsed anthracite coal mine. Perennial ice was demonstrated at two of these sites for the first time during the 2014-2015 season. In both cases, deep man-made recesses allowed the accumulation of significant ice relative to the volume and configuration of the cold trap; in summer, thermal stratification of the air mass further minimized the introduction of warm air and limited the melting of ice. Ice did not persist at sites where the winter/spring accumulation was not sufficient to maintain thermal stratification of the air mass. Sufficient annual melting occurred at sites with perennial ice such that little, if any, continuous ice accumulation over longer periods of time would be expected in the current climate. Most locations in the northeastern United States where the mean annual temperature is lower than the surrounding region are unlikely to develop perennial ice in the absence of heavy winter snow accumulation and sub-freezing spring temperatures. Perennial ice development appears to be restricted to very specific sites with unique geographical features that protect accumulated ice and snow from sunlight and the incursion of warm air.

Green roof growth substrates must be relatively light-weight, retain moisture, be composed of non-toxic materials that do not pollute the associated rainfall and runoff, and allow plant growth. Expanded shales and clays are the most commonly used commercial substrates for this purpose, but they are produced by heating in a high-temperature rotary kiln that requires significant energy input. We are examining the short- and long-term impacts of supplementing conventional green roof growth substrates with available waste products from coal-fired power plants and gas well operations, such as fly and bottom ashes and drill cuttings. These materials may represent satisfactory substitutes for some fraction of less energy efficient growth substrate materials. However, they also have the potential to introduce unacceptable levels of inorganic and organic contaminants to roof runoff, adversely modify soil and runoff pH, and limit plant growth. The screening of over 50 fly and bottom ashes from coal combustion power plants leached with natural rainwater showed a wide range in metal concentrations, with specific heavy metals (Co, Cu, Mn) associated with low pH materials, and As and Cr associated with high pH material. Drill cuttings from a Marcellus gas well in southwestern PA generated high salinity water that was detrimental to seed germination but was rapidly rinsed by rainfall from the solid material. Sedum plants were grown for 16 months on a green roof in pots containing different combinations of coal combustion materials, drill cuttings, conventional green roof soils, and slow-release fertilizer. Plant growth was maximal in the presence of added fertilizer regardless of the primary growth substrate used. Cumulative observations on the growth, germination, and the bioaccumulation of metals and metalloids in the plants are discussed.

Due to the low solubility of barite, chemical approaches to scale prevention involving chelation or inhibition of crystal growth often have limited success in oil field wells. Saline produced waters from Marcellus shale gas wells contain elevated levels of barium, and geochemical equilibrium modeling of these waters indicates that barite is supersaturated throughout the system. Anti-scalant compounds are routinely added to injected waters at Marcellus gas wells as a precautionary measure. Previous laboratory flow-through experiments conducted with recycled produced water, fracturing fluid and Marcellus shale demonstrated barite precipitation on fracture surfaces. Specific factors that may affect barite precipitation in the field, such as pH, solute concentration, the presence of anti-scalant compounds, diffusion gradients, and nucleation sites, are difficult to study based solely on water quality analyses and flow-through laboratory experiments. In this study, we examined physical and chemical factors affecting barite precipitation in Marcellus shale gas waters using two-dimensional diffusion gradient agarose and silica gels. This method allows the counter diffusion of selected ions or chemicals towards each other under conditions of controlled gel permeability and temperature. Using time-lapse photography, the formation of mineral precipitates can be visualized, and changes in precipitation rates due to changes in reactant mixtures and concentrations can be determined. Primary reactant distribution in gels was determined by slicing gels and analyzing the contents, and by microelectrode profiling. Variables potentially influencing barite precipitation in Marcellus waters were tested, including pH, salinity, temperature, major cations in production water (Ba, Sr, Ca), sulfate, and anti-scalant chemicals used to minimize barite precipitation.

CO (sub 2) is injected along with water under pressure and it moves through the pore spaces of the rock, mixes with and lowers the viscosity of the oil, and helps displace oil from the rock formation. The concentration of CO (sub 2) in production water is needed to determine CO (sub 2) breakthrough rates at the production well, as well as identify potential paths of CO (sub 2) leakage into groundwater reservoirs. The CarboQC carbonation meter is used to measure the concentration of CO (sub 2) in water under field conditions by monitoring the temperature and pressure changes during the multiple expansion of a sealed volume of water and calculating the PCO2 from the ideal gas law. This method is effective using carbonated beverages and most natural waters because the solubility of potentially interfering common gases such as O (sub 2) and N (sub 2) is more than 50 times lower in water than it is for CO (sub 2) . Hydrogen sulfide (H (sub 2) S), which is even more soluble than CO (sub 2) in water, is sometimes encountered in very high concentrations in water associated with high-sulfur petroleum deposits or natural gas production, and this directly interferes with CO (sub 2) analysis by volumetric expansion. In this study, we examined the effects of H (sub 2) S on CO (sub 2) measurements in saline produced waters from EOR wells in Texas. Two methods were tested as ways to subtract H (sub 2) S from the dissolved gas fraction. Sulfide was oxidized with hydrogen peroxide, which produced elemental sulfur or sulfate as a reaction product depending on the pH of the water sample, but this generated gas pressure due to peroxide reaction with other organics. Copper sulfate was added to eliminate the dissolved sulfide via precipitation of highly insoluble copper sulfides. Copper sulfides were rapidly precipitated in EOR well samples, but the reaction simultaneously lowered the pH relative to the amount of sulfide present. This resulted in a variable increase in the measured CO (sub 2) due to the conversion of bicarbonate ion to carbonic acid. The potential for this analytical approach to be effective in such waters is further discussed relative to dissolved inorganic carbon content in water and the potential interactions between CO (sub 2) and H (sub 2) S.

One method is to inject as fast as possible until the desired fracture length is obtained. Presented is an alternative injection strategy derived by applying optimal system control theory to the macroscopic mass balance. The picture is that the fracture is constant in aperture, fluid is injected at a controlled rate at the near end, and the fracture unzips at the far end until the desired length is obtained. The velocity of the fluid is governed by Darcy's law with larger permeability for flow along the fracture length. Fracture growth is monitored through micro-seismicity. Since the fluid is assumed to be incompressible, the rate at which fluid is injected is balanced by rate of fracture growth and rate of loss to bounding rock. Minimizing injected fluid loss to the bounding rock is the same as minimizing total injected fluid How to change the injection rate so as to minimize the total injected fluid is a problem in optimal control. For a given total length, the variation of the injected rate is determined by variations in overall time needed to obtain the desired fracture length, the length at any time, and the rate at which the fracture is growing at that time. Optimal control theory leads to a boundary condition and an ordinary differential equation in time whose solution is an injection protocol that minimizes the fluid used under the stated assumptions. That method is to monitor the rate at which the square of the fracture length is growing and adjust the injection rate proportionately.

Responsible and efficient use of the subsurface poses many challenges, many of which require the capability to monitor and manipulate sub-surface stress, fractures, and fluid flow at all scales. Adaptive control of subsurface fractures and flow is a multi-disciplinary challenge that, if achieved, has the potential to transform all subsurface energy strategies. As part of the U.S. Department of Energy's SubTER (Subsurface Technology and Engineering Research development and demonstration) initiative, a multi-National Laboratory team is developing next-generation approaches that will allow for adaptive control of subsurface fractures and flow. SubTER has identified an initial suite of technical thrust areas to focus work, and has initiated a number of small projects. This presentation will describe early progress associated with the SubTER technical topic areas of wellbore integrity, subsurface stress and induced seismicity, permeability manipulation and new subsurface signals.

The Energy Data eXchange (EDX) from Department of Energy's (DOE) National Energy Technology Laboratory (NETL) is an evolving online research environment designed to overcome these challenges in support of DOE's fossil energy goals while offering improved access to data driven products of fossil energy R&D such as datasets, tools, and web applications. In 2011, development of NETL's Energy Data eXchange (EDX) was initiated and offers i) a means for better preserving of NETL's research and development products for future access and re-use, ii) efficient, discoverable access to authoritative, relevant, external resources, and iii) an improved approach and tools to support secure, private collaboration and coordination between multi-organizational teams to meet DOE mission and goals. EDX presently supports fossil energy and SubTER Crosscut research activities, with an ever-growing user base. EDX is built on a heavily customized instance of the open source platform, Comprehensive Knowledge Archive Network (CKAN). EDX connects users to externally relevant data and tools through connecting to external data repositories built on different platforms and other CKAN platforms (e.g. Data.gov). EDX does not download and repost data or tools that already have an online presence. This leads to redundancy and even error. If a relevant resource already has an online instance, is hosted by another online entity, EDX will point users to that external host either using web services, inventorying URLs and other methods. EDX offers users the ability to leverage private-secure capabilities custom built into the system. The team is presently working on version 3 of EDX which will incorporate big data analytical capabilities amongst other advanced features.

These settings are dominantly composed of fine-grained silt and clay lithofacies with typically low vertical permeability, and pore fluids frequently under-saturated with respect to methane. As a result, the pressure-temperature conditions requisite for a GHSZ to be present occur widely worldwide across marine settings, however, the distribution of gas hydrate in these settings is neither ubiquitous nor uniform. This study uses sediment core and borehole related data recovered by drilling at Site 17 in the Andaman Sea during the Indian National Gas Hydrate Program Expedition 1 in 2006, to investigate reservoir-scale controls on gas hydrate distribution. In particular, this study finds that conditions beyond reservoir pressure, temperature, salinity, and gas concentration, appear to influence the concentration of gas hydrate in host sediments. Using field-generated datasets along with newly acquired sedimentology, physical property, imaging and geochemical data with mineral saturation and ion activity products of key mineral phases such as amorphous silica and calcite, we document the presence and nature of secondary precipitates that contributed to anomalous porosity preservation at Site 17 in the Andaman Sea. This study demonstrates the importance of grain-scale subsurface heterogeneities in controlling the occurrence and distribution of concentrated gas hydrate accumulations in marine sediments, and document the importance that increased permeability and enhanced porosity play in supporting gas concentrations sufficient to support gas hydrate formation. This illustrates the complex balance and lithology-driven controls on hydrate accumulations of higher concentrations and offers insights into what may control the occurrence and distribution of gas hydrate in other sedimentary settings.

An increasing emphasis on the commercialization and implementation of this approach to store CO (sub 2) has led to the investigation of the physical processes involved and to the development of system-wide mathematical models for the evaluation of potential geologic storage sites and the risk associated with them. The sub-system components under investigation include the storage reservoir, caprock seals, and the above zone monitoring interval, or AZMI, to name a few. Diffusive leakage of CO (sub 2) through the caprock seal to overlying formations may occur due to its intrinsic permeability and/or the presence of natural/induced fractures. This results in a potential risk to environmental receptors such as underground sources of drinking water. In some instances, leaking CO (sub 2) also has the potential to reach the ground surface and result in atmospheric impacts. In this work, fluid (i.e., CO (sub 2) and brine) flow above the caprock, in the region designated as the AZMI, is modeled for a leakage event of a typical geologic storage system with different possible boundary scenarios. An analytical and approximate solution for radial migration of fluids in the AZMI with continuous inflow of fluids from the reservoir through the caprock has been developed. In its present form, the AZMI model predicts the spatial changes in pressure - gas saturations over time in a layer immediately above the caprock. The modeling is performed for a benchmark case and the data-driven approach of arbitrary Polynomial Chaos (aPC) Expansion is used to quantify the uncertainty of the model outputs based on the uncertainty of model input parameters such as porosity, permeability, formation thickness, and residual brine saturation. The recently developed aPC approach performs stochastic model reduction and approximates the models by a polynomial-based response surface. Finally, a global sensitivity analysis was performed with Sobol indices based on the aPC technique to determine the relative importance of these input parameters on the model output space.

The approach taken uses reduced order models so that systems simulations occur rapidly, even for simulations times of hundreds to thousands of years. In that way, uncertainties of the entire system can be probed in a reasonable time period, using a Monte Carlo approach. The model presented here uses third generation NRAP ROMs that are able to realistically represent several key properties of reservoirs, wells, seals, and groundwater aquifers. Results from the NRAP-IAM-CS model are used to quantify risk profiles for selected parameter distributions of reservoir properties, seal properties, numbers of wells, well properties, thief zones, and groundwater aquifer properties. A series of risk profiles show how the risk under different storage conditions evolves over time, both during injection, in the near-term post injection period, and over the long term. In this study, the NRAP-IAM-CS was also used to investigate the importance of different parameters across the system on risk of leakage and risk of groundwater contamination, under different storage conditions.

It is imperative to understand the processes that influence fracture properties in order to accurately predict subsurface behavior. In order to evaluate the coupled hydrologic and geometric changes to a fracture undergoing shear displacement, a novel apparatus was used to produce real-time shearing of fractured shale at elevated pressures. Intermittent computed tomography (CT) scans were performed during each shearing event and transmissivity measurements taken to characterize both the mechanical evolution as well as the hydrodynamic response of the fracture. The initial fractures examined had small apertures and high resistance to flow, with most aperture values below the resolution of the CT scanner and low transmissivities. Initial shearing events, with total displacement less than two mm, minimally increased the aperture and increased the transmissivity. Further shearing resulted in fracture apertures that were large with pressure differentials across the core below the detection limit of the pressure measurement equipment. Flow models using the complex fracture geometries obtained from the CT scanning was performed to examine the micro-scale impacts of fracture evolution on the flow field that were not apparent in the bulk data. These results showed strong flow channelization within the larger aperture regions and showed that hydraulic aperture was significantly different than average mechanical apertures. Fracture aperture evolution due to shearing was characterized with the resulting mechanical and hydrologic responses. Apertures showed increases after each shearing event. Additionally, this increased aperture resulted in increased transmissivity and subsequent increases in hydraulic aperture. Coupling the experimental work with computational analysis provided further insight into the evolution of fracture flow properties.

Simon Sandstone in the Illinois Basin AN - 1824215402; 2016-082521 AB - In order to understand subsurface flow dynamics, including CO (sub 2) plume migration and capillary trapping, a diverse set of geologic properties within the reservoir, from the pore scale to the basin scale, must be understood and quantified. The uncertainty about site-specific geology stems from the inherent variation in rock types, depositional environments, and diagenesis. In collaboration with geocellular and multiphase modeling, detailed characterization of the Lower Mt. Simon Sandstone (LMSS), a reservoir utilized for carbon capture storage, is supporting data-driven conceptual models to better understand reservoir heterogeneity and its relationship to reservoir properties. This includes characterization of sedimentary facies and pore scale modeling of the reservoir The Cambrian-age Lower Mt. Simon Sandstone (LMSS) is a reservoir utilized for two-different carbon capture storage projects in the Illinois Basin, USA. The LMSS is interpreted to have formed in a braided river environment comprising a hierarchy of stratification, with larger scale depositional facies comprising assemblages of smaller scale facies. The proportions, geometries, length scales, and petrophysical attributes of the depositional facies, and of the textural facies they comprise, are being quantified. Based on examination of core and analog outcrop in adjacent areas, the LMSS is comprised of five dominant depositional facies, the most abundant facies being planar to trough cross-bedded sandstones produced by subaqueous sand dunes. This facies has the best reservoir conditions with porosity up to 27% and permeability up to 470 mD. Three-dimensional pore network modeling via micro computed tomography of this facies shows well-connected and unobstructed pore throats and pore space. This presentation will outline the depositional heterogeneity of the LMSS, its relationship to diagenetic fabrics, and its influence on fluid movement within the reservoir.

For tight sand and shale formations, fluid flow is primarily restricted to fractures within each rock layer. NFFLOW was designed by the Department of Energy to model gas well production from naturally fractured reservoirs. NFFLOW is a discrete fracture simulator, with every fracture and rock matrix in the domain handled individually. One-dimensional models are used calculate the flow through connected fractures and flow from the surrounding rocks into fractures. Flow into well bores are determined from the combined flux from connecting fractures and adjacent rock matrices. One-dimensional fluid flow equations are used because they are extremely fast to solve and represent a reasonable approximation of the physical behavior of fluids in most of the reservoir. However, near the wellbore those models become inaccurate due to gas flow convergence, which is a multidimensional situation. We present a method to correct the one-dimensional models, using data from two-dimensional fluid flow models, while maintaining the original simulator speed. By applying corrections from the two-dimensional model, the one-dimensional models can better account for gas flow convergence into the wellbore as well as the location of the wellbore within the rock strata. Corrections were successful in scaling the one-dimensional flow rates to match the two dimensional values over a wide range of parameters for both fracture flow and porous media flow into the wellbore. This is shown to increase the accuracy of history matching to production data for a wide range of wells, allowing for better modeling and prediction of future productivity. With an accurate history match established, NFFLOW can then be used to investigate issues such as the ability of the formation to sequester carbon dioxide or the effects of additional hydraulic fracturing on fluid transport.

The low-permeability formation requires hydraulic fracturing to be produced. In this process, millions of gallons of water are blended with chemical additives and pumped into each well to fracture the reservoir rock. Although additives account for less than 2% of the fracking fluid mixture, they amount to hundreds of tons per frack job. The environmental properties of some of these additives have been studied, but their behavior under downhole conditions is not widely reported in the peer-reviewed literature. These compounds and their reaction products may return to the surface as produced or waste water. In the event of a spill or release, this water has the potential to contaminate surface soil and water. Of these additives, biocides may present a formidable challenge to water quality. Biocides are toxic compounds (by design), typically added to the Marcellus Shale to control bacteria in the well. An assessment of the most frequently used biocides indicated a need to study the chemical dazomet under reservoir conditions. The Marcellus Shale contains significant deposits of pyrite. This is a ubiquitous mineral within black shales that is known to react with organic compounds in both oxic and anoxic settings. Thus, the objective of our study was to determine the effect of pyrite on the hydrolysis of dazomet. Liquid chromatography-triple quadrupole mass spectrometry (LC-QQQ) was used to calculate the loss rate of aqueous dazomet. Gas chromatography-mass spectrometry (GC-MS) was used to identify the reaction products. Our experiments show that in water, dazomet rapidly hydrolyses in water to form organic and inorganic transformation products. This reaction rate was unaffected when performed under anoxic conditions. However, with pyrite we found an appreciable increase in the removal rate of dazomet. This was accompanied by a corresponding change in the distribution of observed reaction products. Our results indicate the need to determine specific mineral-additive interactions to evaluate the potential risks of chemical use in hydraulic fracturing.

Prior investigations showed that elevated Li in saline waters co-produced with natural gas during Marcellus Shale development resulted from mixing of hydraulic fracturing fluid (HFF) and Li-rich formation water. However, specific contributions to the Li isotope signature from reactions between the HFF and shale remained unclear. This study focused on HFF-shale reactions that could affect the Li budget and isotope composition in Marcellus Shale produced water in a series of flow through experiments conducted at fixed temperature and pressure (66 degrees C, 20MPa) comparable to formation conditions. Synthetic HFF was prepared by mixing either freshwater or a lab-derived saline water with chemical additives commonly used in hydraulic fracturing. Outcrop cores of Marcellus Shale were artificially fractured either parallel to or perpendicular to bedding prior to loading into the flow-through apparatus, and each experiment was performed with a unique HFF composition continuously pumped through a fresh core (15 cm in length, 3.8 cm in diameter). Initial fluid and cumulative effluents collected after 2 days and 7 days from the start of the experiment were measured for concentrations of cations and anions. Multi-collector ICP-MS was used to measure lithium isotope ratios (delta (super 7) Li). Preliminary results show that dissolution of carbonate minerals occurred in both replicate experiments with freshwater-based HFF (pH 2) as shown by a large decrease in Li/Ca from 0.8 (initial fluid) to 0.003 (effluents on day 2 and day 7) with no significant change in Li concentration. This is consistent with low Li in carbonate cement (45 days after production) in produced water samples from the field. Results to date suggest that HFF-shale reactions have a minimal effect on the Li isotopic signature of Marcellus Shale produced waters.

Shale-HFF interaction could cause mineral dissolution, releasing matter from the shale, or mineral precipitation that degrades reservoir permeability. Furthermore, data are limited on whether scale inhibitors are effective at preventing mineral precipitation and whether these inhibitors adversely affect reservoir fluid chemistry and permeability. To investigate HFF-rock interaction within shale reservoirs, we conducted flow-through experiments exposing Marcellus Shale to synthetic HFF at reservoir conditions (66oC, 20MPa). Outcrop shale samples were cored, artificially fractured, and propped open with quartz sand. Synthetic HFFs were mixed with chemical additives similar to those used for Marcellus Shale gas wells in Ohio and Southwestern Pennsylvania (FracFocus.org). We evaluated differences between shale reactions with HFF made from natural freshwater and reactions with HFF made from synthetic produced water (designed to simulate produced water that is diluted and re-used for subsequent hydraulic fracturing). We also compared reactions with HFFs including hydrochloric acid (HCl) to represent the initial acid stage, and HFFs excluding HCl. Reactions were determined through changes in fluid chemistry and X-ray CT and SEM imaging of the shale before and after experiments. Results from experiments with HFF containing HCl showed dissolution of primary calcite, as expected. Experiments using HFF made from synthetic produced water had significant mineral precipitation, particularly of barium and calcium sulfates. X-ray CT images from these experiments indicate precipitation of minerals occurred either along the main fracture or within smaller splay fractures, depending on fluid composition. These experiments suggest that HFF reaction with shale may significantly alter reservoir mineralogy and could damage reservoir permeability with secondary mineral precipitation. This topic deserves further study as gas production rates and ultimate recovery may be suboptimal, with consequential increases in the footprint of natural gas extraction.

Hydrate distribution in sediments may cause the bulk physical properties of their host sediments varying several orders of magnitude even with the same amount of hydrate. In natural sediments, hydrate morphology is inherently governed by the burial depth and the grain size of the host sediments. Compare with patchy hydrate, uniformly distributed hydrate is more destructive to fluid flow, yet leads to higher gas and water permeability during hydrate dissociation due to the easiness of forming percolation paths. Water and hydrate have similar thermal conductivity values; the bulk thermal conductivity of hydrate-bearing sediments depends critically on gas-phase saturation. 60% of gas saturation may result in evident thermal conductivity drop and hinder further gas production. Sediments with patchy hydrate yield lower stiffness than that with cementing hydrate but higher stiffness than that with pore filling and loading bearing hydrate. Besides hydrate distribution, the stress state and loading history also play an important role in the mechanical behavior of hydrate-bearing sediments.

One way to establish credence is to investigate if observation from laboratory tests could be reproduced in analysis. From this consideration, this study modeled laboratory triaxial tests in which hydrate dissociation was induced when a certain level of shear stress was reached. During the dissociation, however, both the axial and the confining stresses were kept unchanged. There were basically two scenarios observed: If the applied shear stress was higher than the shear strength of the hydrate free host soil, failure would take place during the dissociation; otherwise the sample would remain stable. The dissociation was induced either by a temperature raise or through pore pressure reduction. To model such tests, a coupled procedure was employed: the geomechanical analysis was conducted in FLAC3D, and the multiphase flow was conducted in TOUGH+. In this study, an SMP critical state constitutive model was implemented in the FLAC3D. This study successfully reproduced the observation from the laboratory tests. It showed that if the dissociation was caused by temperature change alone, failure would take place during dissociation. On the other hand, the modeling results also showed that if the dissociation was induced by pressure reduction, a sample could remain stable during dissociation because the effective confining stress was raised, but it would fail afterwards when the pre-association fluid pressure was allowed to return and the pace of hydrate reformation lagged behind.

That technique would serve the dual purpose of CO (sub 2) sequestration and production of CH (sub 4) while maintaining the geo-mechanical stability of the reservoir. In order to analyze CH (sub 4) production process by means of CO (sub 2) or CO (sub 2) +N (sub 2) injection into gas hydrate reservoirs, a new simulation tool, Mix3HydrateResSim (Mix3HRS)[1], was previously developed to account for the complex thermodynamics of multi-component hydrate phase and to predict the process of CH (sub 4) substitution by CO (sub 2) (and N (sub 2) ) in the hydrate lattice. In this work, Mix3HRS is used to simulate the CO (sub 2) injection into a Class 2 hydrate accumulation characterized by a mobile aqueous phase underneath a hydrate bearing sediment. That type of hydrate reservoir is broadly confirmed in permafrost and along seashore. The production technique implies a two-stage approach using a two-well design, one for an injector and one for a producer. First, the CO (sub 2) is injected into the mobile aqueous phase to convert it into immobile CO (sub 2) hydrate and to initiate CH (sub 4) release from gas hydrate across the hydrate-water boundary (generally designating the onset of a hydrate stability zone). Second, CH (sub 4) hydrate decomposition is induced by the depressurization method at a producer to estimate gas production potential over 30 years. The conversion of the free water phase into the CO (sub 2) hydrate significantly reduces competitive water production in the second stage, thereby improving the methane gas production. A base case using only the depressurization stage is conducted to compare with enhanced gas production predicted by the CO (sub 2) -assisted technique. The approach also offers a possibility to permanently store carbon dioxide in the underground formation to greater extent comparing to a direct injection of CO (sub 2) into gas hydrate sediment. Numerical models are based on the hydrate formations at the Prudhoe Bay L-Pad region on the Alaska North Slope. References [1] N.

Optical waveguide-based sensing technologies have become increasingly important for harsh environment energy applications. In this manuscript, we present sensing results for fiber-optic evanescent wave hydrogen sensors employing La-doped SrTiO3 layers as the active sensing element. These sensors show a rapid, reproducible sensing response to hydrogen fuel gas streams at elevated temperatures (600-800 degree C). The presence of hydrogen results in a reversible and reproducible decrease in near-infrared transmission through the sensor. Sensors were also tested directly in the anode assembly of an operating solid oxide fuel cell (SOFC) with the sensor response correlating with both H2 concentration and SOFC cell potential.

The challenges come from the complexity of the physics from the tool-rock interaction to the fracture process and propagation of the quasibrittle rocks. This study was aimed at developing a finite element procedure that was capable of providing reasonable estimates of cutting forces and, at the same time, capturing the essential characteristics of the fragmentation process. Published laboratory rock scratch tests were used as modeling targets since these tests encompass all essential characteristics of rock cutting. Both shallow cuts and deep cuts from a rectangular cutter were analyzed first, followed by modeling of shallow cuts from a disc cutter. It was concluded that rock cutting could be reasonably modeled by using a plasticity-damage model, an element erosion scheme that removes an element when its energy release equals fracture energy, together with a proper selection of modeling parameters.

AN - 1756508239; 2016-005528 AB - Shale gas development in the United States has revolutionized energy production and supply, making the nation energy independent for the first time in decades. However, many people remain concerned that the large-scale hydraulic fracturing necessary to recover hydrocarbons from shale may degrade the environment, including groundwater. Improving the understanding of how groundwater may be impacted by shale gas development requires field monitoring at multiple sites on different shale plays under a variety of climates and hydrologic conditions. Such monitoring has been difficult to achieve because of a lack of access to commercial sites and an absence of funding to drill dedicated research wells.

Drilling challenges at such extreme conditions prompted NETL to develop a specialized ultra-deep drilling simulator (UDS) for investigating drill behavior in such conditions. Using the UDS apparatus, complex laboratory tests were performed on Carthage marble (Warsaw limestone) and Crab Orchard sandstone, which represent the rocks in the basins of the Tuscaloosa trend in southern Louisiana and the Arbuckle play in Oklahoma and North Texas. Additionally, numerical models of the UDS were developed for performing parametric analyses that would be impossible with the UDS alone. Subsequently, it was found that the input properties for these two rock types at such extreme pressure and temperature conditions were unavailable. Therefore, a suite of unconfined compressive strength, indirect tensile strength, and triaxial compression tests (sigma (sub 1) > sigma (sub 2) = sigma (sub 3) ) were performed on Carthage marble and Crab Orchard sandstone for investigating their behavior in HPHT environments. The HPHT experiments were performed at confining pressures ranging from atmospheric to 200 MPa, and with temperatures ranging from 25 to 180 degrees C. The influences of confining pressure and temperature on the mechanical properties of two rocks were investigated.

At a given CO sub(2) pressure, the turnover temperature (T sub(t)) of the reaction of an individual solid that can capture CO sub(2) is fixed. Such T sub(t) may be outside the operating temperature range ( Delta T sub(o)) for a practical capture technology. To adjust T sub(t) to fit the practical Delta T sub(o), in this study, three scenarios of mixing schemes are explored by combining thermodynamic database mining with first principles density functional theory (DFT) and phonon lattice dynamics calculations. Our calculated results demonstrate that by mixing different types of solids, it's possible to shift T sub(t) to the range of practical operating temperature conditions. According to the requirements imposed by the pre- and post- combustion technologies and based on our calculated thermodynamic properties for the CO sub(2) capture reactions by the mixed solids of interest, we were able to identify the mixing ratios of two or more solids to form new sorbent materials for which lower capture energy costs are expected at the desired pressure and temperature conditions.

AN - 1701894513; 26154523 AB - Natural gas extraction from Marcellus Shale generates large quantities of flowback water that contain high levels of salinity, heavy metals, and naturally occurring radioactive material (NORM). This water is typically stored in centralized storage impoundments or tanks prior to reuse, treatment or disposal. The fate of Ra-226, which is the dominant NORM component in flowback water, in three centralized storage impoundments in southwestern Pennsylvania was investigated during a 2.5-year period. Field sampling revealed that Ra-226 concentration in these storage facilities depends on the management strategy but is generally increasing during the reuse of flowback water for hydraulic fracturing. In addition, Ra-226 is enriched in the bottom solids (e.g., impoundment sludge), where it increased from less than 10 pCi/g for fresh sludge to several hundred pCi/g for aged sludge. A combination of sequential extraction procedure (SEP) and chemical composition analysis of impoundment sludge revealed that Barite is the main carrier of Ra-226 in the sludge. Toxicity characteristic leaching procedure (TCLP) (EPA Method 1311) was used to assess the leaching behavior of Ra-226 in the impoundment sludge and its implications for waste management strategies for this low-level radioactive solid waste. Radiation exposure for on-site workers calculated using the RESRAD model showed that the radiation dose equivalent for the baseline conditions was well below the NRC limit for the general public.

This study uses the transient plane source (TPS) technique to measure the thermal conductivity of methane hydrate-bearing sediments with various hydrate/water/gas saturations. We propose a simplified method to obtain thermal properties from single-sided TPS signatures. Results reveal that both volume fraction and distribution of the pore constituents govern the thermal conductivity of unsaturated specimens. Thermal conductivity hysteresis is observed due to water redistribution and fabric change caused by hydrate formation and dissociation. Measured thermal conductivity increases evidently when hydrate saturation S sub(h)>30-40%, shifting upward from the geometric mean model prediction to a Pythagorean mixing model. These observations envisage a significant drop in sediment thermal conductivity when residual hydrate/water saturation falls below ~40%, hindering further gas production.

AN - 1762378599; PQ0002505260 AB - The Marcellus Shale is an important hydrocarbon source rock and an unconventional reservoir whose origin has engendered much recent debate among geologists. Our analysis of the formation in West Virginia and adjacent States aims to identify and describe the several lithofacies in the eastern Appalachian basin and to interpret their depositional setting. The study is based on field, hand-sample, and microscopic observations, supplemented by X-ray diffraction, thermogravimetric, and gamma-ray-scintillometer data. We identify five major lithofacies: (1) calcitic coarse mudstone, quartz-silty and sparsely fossiliferous; (2) skeletal wackestone-packstone limestone, exhibiting a low to moderate faunal diversity; (3) calcitic carbonaceous medium mudstone, containing a high organic-carbon content and low-density, low-diversity fossil community; (4) siliceous carbonaceous fine mudstone, exceedingly radioactive with a high organic-carbon content and usually barren of benthic fossils; and (5) argillaceous coarse mudstone, quartz-silty, micaceous, and kaolinitic. Most layers of Facies 4 mudstone-the quintessential black shale of the Marcellus- formed in a stagnant, anoxic environment beneath a stratified water column and starved of terrigenous sediment.

This has become particularly common in the U.S. Gulf of Mexico. In this study we develop a spatial vulnerability approach and example assessment to support future spill prevention and improve future response readiness. This effort, which is part of a larger integrated assessment modeling spill prevention effort, incorporated economic and environmental data, and utilized a novel new oil spill simulation model from the U.S. Department of Energy's National Energy Technology Laboratory, the Blowout and Spill Occurrence Model (BLOSOM). Specifically, this study demonstrated a novel approach to evaluate potential impacts of hypothetical spill simulations at varying depths and locations in the northern Gulf of Mexico. The simulations are analyzed to assess spatial and temporal trends associated with the oil spill. The approach itself demonstrates how these data, tools and techniques can be used to evaluate potential spatial vulnerability of Gulf communities for various spill scenarios. Results of the hypothetical scenarios evaluated in this study suggest that under conditions like those simulated, a strong westward push by ocean currents and tides may increase the impacts of deep water spills along the Texas coastline, amplifying the vulnerability of communities on the local barrier islands. Ultimately, this approach can be used further to assess a range of conditions and scenarios to better understand potential risks and improve informed decision making for operators, responders, and a of stakeholders to support spill prevention as well as response readiness.

A literature review on many previously conducted investigations shows that the mechanical properties of a clayey cap rock, such as Young's moduli and Poisson's ratios, are relatively constrained to a small range of potential values in comparison to the permeability, which can vary greatly by many orders of magnitude. We found that the shear stress on the interface between the aquifer and cap rock results in very different temporal behaviors in response to different cap rock permeability. The largest shear stress changes concentrate on the near well region and remain stationary over a long period of time if the cap rock has very low permeability. The shear stresses increase greatly in the near well region at early times but the largest increases tend to migrate to the far side for semi-pervious or pervious cap rock conditions. Shear stress near the well may experience a reversion at the interface due to the delayed expansion of the cap rock if the cap rock is semi-pervious and more expansive than the aquifer formation. Because of the difficulty in measuring the stresses at depth, these stress changes may only be inferred from in-direct signals, such as induced seismicity. This poses the possibility that we may be able to inversely evaluate whether a cap rock formation is tight (very impermeable), or semi-pervious or even permeable by detecting the temporal and spatial occurrences of seismic swarms on the rock interface associated with fluid injection.

Optical-based approaches offer significant safety advantages as compared to electrical-based sensors and Pd or AuPd-alloys are commonly utilized as the functional sensor layer due to a well-known, characteristic, and selective interaction with H2. In this work, optical fiber-based sensors comprised of Pd and AuPd alloy nanoparticle incorporated SiO2 thin films deposited onto unclad multimode silica-based optical fiber evanescent wave absorption spectroscopy sensing elements have been investigated. Selective, sensitive, and monotonic H2 sensing responses have been demonstrated at levels significantly greater than the lower explosive limit in the presence of CO and O2 near room temperature. A tendency for partial oxidation of the noble metal nanoparticles upon exposure to oxidizing atmospheres is confirmed directly through X-ray photoelectron spectroscopy, particularly at elevated temperatures. Monotonic H2 sensing responses are also observed at elevated temperatures in cases where oxygen is not introduced into the atmosphere. However, more complex sensing responses in multi-component elevated temperature gas streams containing oxidizing and reducing species can be observed which likely result from oxidation and reduction of noble metal nanoparticles. These results demonstrate that the incorporation of noble metals such as Pd and Pd-alloy nanoparticles into inert dielectric matrices such as SiO2 can impart new optical sensing functionality potentially useful for H2 sensing applications.

The model predicted a permeability decrease from 1.60 mD to 1.02 mD for the Mount Simon sandstone sample in a static batch reactor after 180 days of exposure to CO (sub 2) -saturated brine, which is consistent with measured permeability results. Model-predicted solution chemistry results were also consistent with laboratory-measured solution chemistry data. SiO (sub 2) (am) was the primary mineral that causes permeability decrease, followed by kaolinite. Both SiO (sub 2) (am) formation and kaolinite formation were attributed to the dissolution of quartz and feldspar. This study shows that the formation of SiO (sub 2) (am) and kaolinite in the pore space of host rock is possible under typical CO (sub 2) sequestration conditions. SiO (sub 2) (am) and kaolinite precipitation at the CO (sub 2) plume extent could reduce the permeability of host rock and improve lateral containment of free-phase CO (sub 2) , contributing to overall security of CO (sub 2) storage.

Calcium is primarily used in the formation of gels for biomass immobilization due to its lack of toxicity, but these cations are known to show differing affinities for alginate. Marcellus flowback water from southwestern PA is of high salinity (37 g/L Na) and contains high concentrations of divalent ions Ca>Ba>Sr>Fe>Mn in the ratio of 1843:479:389:20:1. In this study, we examined the selectivity for sequestration of these ions within alginate gel by polymerization and further diffusion and potential displacement reactions. The gel beads were formed by dropping two percent aqueous sodium alginate directly into Marcellus flowback water. The major divalent ions were concentrated Ba>Sr>Ca in alginate gel relative to in situ values. Applications of this technique for water treatment purposes and improving the accuracy of ICP-MS analysis of rare earth and other elements are presented.

The distilled kerosene fraction was further refined by adding concentrated sulfuric acid to oxidize and remove higher molecular weight hydrocarbons and tars to clarify the kerosene and reduce smoke production during burning. Waste tar-laden and diluted sulfuric acid from Titusville, PA refineries was sent by rail to a factory two miles away where the tar was removed and concentrated sulfuric acid was produced by distillation. Today, the factory site remains unvegetated nearly 100 years after its closing, and the soil is highly contaminated with lead and acid tar. The acid tar is believed to provide a semi-continuous source of sulfuric acid, organic acids, and other heavy metals. The periodic warming of tar deposits exposes new surface area to contact with rainwater and generation of more contaminants associated with acid tar. In this report, we present the initial characterization of representative tar samples from the site. The tar had a dry wt of ca. 65%, a bulk density of 1.7, and contained ca. 2 and 21 g/kg total Pb and sulfate as sulfuric acid, respectively, along with detectable concentrations of As and Sb, common Pb alloying elements. Organic analysis of the tar was performed using liquid chromatography/quadrupole time-of-flight mass spectrometry (LC/Q-TOF-MS), and detected a wide range of compounds, including polyaromatic hydrocarbons. Results of these studies will be used to design feasible bioremediation approaches for the reclamation of the contaminated site.

Alginate hydrogel beads have been used as tracers to mimic the free-phase transport of organic compounds less dense than water (LNAPLs) by adding flotation agents (glass beads, gas inclusions) to the alginate matrix. In this study, we added relatively dense barite (BaSO4) powder to produce alginate hydrogel beads that could be designed to mimic the density of NAPLs between 1.01 and 1.83 g cm-3. Beads mimicking the density of free-phase organic contaminants relevant to Superfund sites were produced in the laboratory. Increased alginate concentrations produced stronger gel beads with greater resistance to sediment abrasion. Fluorescent pigment powders were added to differentiate beads representing specific organic compounds. Experimentally measured minimum stream flow velocities needed to transport barite-modified hydrogel beads were consistent with anticipated and measured bead densities.

The CarboQC carbonation meter is a method of CO2 analysis in water that is based on the ideal gas law by measuring equilibrium temperature and pressure resulting from the multiple expansion of a sealed sample volume. This method is effective using carbonated beverages and most natural waters because the solubility of potentially interfering O2 and N2 gases is over 50 times lower in water than it is for CO2. However, hydrogen sulfide (H2S), which is even more soluble than CO2 in water, is occasionally encountered in very high concentrations in groundwater samples, especially those associated with high-S petroleum deposits or natural gas production. In this study, we examined the effects of H2S associated with water samples from a natural spring in Virginia and saline produced waters from enhanced oil recovery (EOR) wells in Texas on the measurement of CO2 using the CarboQC meter. Both copper sulfate and zinc acetate were tested as ways of eliminating the H2S fraction via precipitation of metal sulfides and determining the CO2 concentration by difference. Copper sulfide was rapidly precipitated in EOR well samples containing 500-800 mg/L H2S, but the reaction simultaneously lowered the pH to ca. 1.5. As a result, detectable CO2 levels were actually increased due to the net acidification of the sample. The potential for this analytical approach to be effective in such waters is considered and discussed relative to recently observed effects on the mutual interaction between the two gases and their respective solubilities in water.

Reactive transport modeling and simulations can anticipate expected geochemical transformations due to CO2 leaks within a given aquifer, but field experiments are still necessary to critique model predictions and to document in situ reaction rates. Geological formations associated with storage sites may include a wide range of reactive silicate, oxide, oxyhydroxide, carbonate, and sulfide minerals, and the stability of these minerals may be affected when aqueous chemical equilibria are modified by leaking CO2. In this study, we propose the use of laser-induced breakdown spectroscopy (LIBS) to monitor the precipitation and dissolution of carbonate minerals in the presence of CO2. The technique has successfully been used to conduct laboratory-scale experiments to measure calcium and other cations in aqueous samples. Stability fields for a wide range of carbonate minerals over a pH range of 5-8 were determined by geochemical modeling. Experiments using ICP analysis detected changes in dissolved divalent ions due to precipitation and dissolution reactions when CO2 gas was added incrementally. The aim of this research is to develop a method for in situ monitoring of CO2 leakage into groundwater aquifers.

The most difficult challenge is accessing defect free and optimized MMM membranes. Defects are generally due to incompatible interfaces between the polymer and the filler particle. Herein, we present a new approach to modify and optimize the surface of UiO-66-NH sub(2) based MOF particles to improve its interaction with Matrimid super( registered ) polymer. A series of surface modified UiO-66-NH sub(2) particles were synthesized and characterized using super(1)H NMR spectroscopy, mass spectrometry, XPS, and powder X-ray diffraction. MMMs containing surface optimized MOF particles exhibit improved thermal and mechanical properties. Most importantly, the MMMs show significantly enhanced gas separation properties; CO sub(2) permeability was increased by similar to 200% and CO sub(2)/N sub(2) ideal selectivity was increased by similar to 25%. These results confirm the success of the proposed technique to mitigate defective MOF/Matrimid super( registered ) interfaces. JF - Journal of materials chemistry.

The study had two research objectives: 1) to determine the maximum height of fractures created by hydraulic fracturing at this location; and 2) to determine if natural gas or fluids from the hydraulically fractured Marcellus Shale had migrated 3,800 ft upward to an overlying Upper Devonian/Lower Mississippian gas field during or after hydraulic fracturing. Microseismic monitoring using vertical geophone arrays located 10,288 microseismic events during hydraulic fracturing; all events were at least 2,000 ft below producing zones in the overlying Upper Devonian/Lower Mississippian gas field, and more than 5,000 ft below drinking water aquifers. Monitoring for evidence of fluid and gas migration was performed during and after the hydraulic fracturing of six horizontal Marcellus Shale gas wells and included: 1) gas pressure and production histories of three Upper Devonian/Lower Mississippian wells; 2) chemical and isotopic analysis of the gas produced from seven Upper Devonian/Lower Mississippian wells; 3) chemical and isotopic analysis of water produced from five Upper Devonian/Lower Mississippian wells; and 4) monitoring for perfluorocarbon tracers in gas produced from two Upper Devonian/Lower Mississippian wells. Current findings are: 1) no evidence of gas migration from the Marcellus Shale; and 2) no evidence of brine migration from the Marcellus Shale. Four perfluorocarbon tracers were injected with hydraulic fracturing fluids into 10 stages of a 14-stage, horizontal Marcellus Shale gas well during stimulation. Gas samples collected from two Upper Devonian/Lower Mississippian wells that directly overlie the tracer injection well were analyzed for presence of the tracer. No tracer was found in 17 gas samples taken from each of the two wells during the 2-month period after completion of the hydraulic fracturing. Conclusions of this study are: 1) the impact of hydraulic fracturing on the rock mass did not extend to the Upper Devonian/Lower Mississippian gas field; and 2) there has been no detectable migration of gas or aqueous fluids to the Upper Devonian/Lower Mississippian gas field during the monitored period after hydraulic fracturing.

Consequently, we evaluate diel cycles of DIC, CO (sub 2) , and delta (super 13) C (sub DIC) in mine drainage in north-central West Virginia in late winter, mid spring, and summer at two sites along the drainage stream. The upstream site (50 m from the mine portal) is lined with limestone riprap and is exposed to less direct sunlight, has less emergent vegetation, and exhibits a faster flow rate than the downstream site (138 m from the mine portal), which is in an altered natural wetland. The differences in characteristics were expected to affect the diel cycling of CO (sub 2) and DIC, and thus impact other solute compositions. The data were fit using a cosine model to assess the magnitude and phase of diel cycles, and the goodness of fit of the model was determined using an F-test statistic. DIC concentrations were higher at the upstream site (2.09 mM - 3.35 mM) than the downstream site (1.11 mM - 1.77) as CO (sub 2) degasses downstream. Over the three sampling periods, DIC and CO (sub 2) concentrations remained approximately constant at the upstream site but decreased slightly over time at the downstream site as temperature increased from winter to summer. The downstream site in late winter exhibited the best fit cycle with the DIC and CO (sub 2) increasing during the nighttime concurrent with a decrease in pH and delta (super 13) C (sub DIC) values. These changes are consistent with the release of CO (sub 2) during plant and sedimentary respiration, while the daytime increase in delta (super 13) C (sub DIC) values during the day is consistent with photosynthesis. Significant cycles (at a < 0.01) include (1) DIC-late winter and summer at the downstream site; (2) CO (sub 2) -only during late winter at both sites; and, (3) delta (super 13) C (sub DIC) -during spring and summer at the downstream site. Mechanisms likely controlling diel cycles of these parameters are temperature-dependent CO (sub 2) degassing, photosynthesis- respiration diel cycles in plants and sediments, and interactions with the metals present at high concentrations in the mine water.

The rapid growth of these technologies has placed considerable economic pressure on sourcing REEs, with the current global supply dominated by mineral deposits in China. In light of this global demand for REEs, alternative sources are an area of active exploration. One potential source is ancient sedimentary black shale deposits that are currently being exploited for natural gas and oil resources. Past environmental conditions that promoted the accumulation of these black shale units were also interconnected with the cycling of sedimentary phosphorus, which is thought to be a major control on the accumulation of REEs in sediments. Drilling operations to extract natural gas from black shale units present a concomitant potential to remobilize the REEs and bring them to the surface for further extraction. However, the geochemical reactions that determine the mobility of REEs between the native black shale rock and the introduced hydraulic fracturing drilling fluids are not well understood. We present the results of our experiment as a basis for understanding these reactions between the drilling fluid and the targeted rock formations. We reacted black shale samples from the Marcellus Formation in southwestern Pennsylvania with a NaCl brine and a synthesized hydraulic fracturing fluid (FF) for a duration of one week under high temperatures and pressures that approximated those from 2.5 km below the surface. Preliminary analysis of the reacted fluids shows evidence for the dissolution of carbonates with an increase in dissolved Ca (44,000-190,000 mu g/L) after one week. The presence of the synthesized FF versus the NaCl brine does not appear to have a noticeable effect on the major cation solution chemistry. The REEs show little change in the fluid phase during reactions with the NaCl brine, but do show slight decreases (<8 mu g/L for all REEs) during the reaction with synthesized FF. These preliminary results suggest that the net mobility of REEs during reactions between fluid and rock is minor, although this could be an artifact of the particular rock samples utilized that may not be representative of the Marcellus Formation as a whole.

The intent was to engage tribal college students in the oil and gas resource evaluation process, which could perhaps lead to interest and future careers in energy exploration and production. The project was funded by the American Indian Higher Education Consortium (AIHEC) and the American Indian Science & Engineering Society (AISES), with in-kind contributions from NETL that included gas shale expertise, geological characterization, and geochemical analyses. The tribal government desired an objective, practical assessment of the resource from the college. Potential development could lead to more jobs, economic opportunities, and affordable energy on the reservation. The Niobrara is a significant play in Colorado and Wyoming, but is not produced commercially in South Dakota. Project objectives were to characterize the stratigraphy, composition, depositional environments, reservoir properties, regional trends, structural features, and potentially-productive areas of the formation on the reservation. Several professors and research scientists provided guidance to undergraduate STEM students, graduate geology students, and post-graduate interns. Niobrara drill cores were sampled at the USGS core library, and the state geological survey provided access to new core from the Niobrara Formation south of Presho, SD. Although relatively shallow under the reservation, the Niobrara may contain as much as 6% organic matter with a thermal maturity in the biogenic gas window. Any energy development on tribal land would require environmental monitoring, which has also engaged students. The Niobrara at Rosebud is not anticipated to produce large amounts of gas that would justify a pipeline connection. The gas will have to be used locally, prompting additional research on utilization technology. The relatively inexpensive drilling costs may provide the tribe with a secure and economical energy supply, suggesting an approach for stranded gas development that could be applied elsewhere.

However, gas-hydrate recovery is both a scientific and a technical challenge and much remains to be learned about the geologic, engineering, and economic factors controlling the ultimate energy resource potential of gas hydrate. The amount of natural gas contained in the world's gas-hydrate accumulations is enormous, but these estimates are speculative and range over three orders of magnitude from about 2,800 to 8,000,000 trillion cubic meters of gas. By comparison, conventional natural gas accumulations (reserves and undiscovered, technically recoverable resources) for the world are estimated at approximately 440 trillion cubic meters. Gas recovery from gas hydrate is hindered because the gas is in a solid form and because gas hydrate commonly occurs in remote Arctic and deep marine environments. Proposed methods of gas recovery from gas hydrate generally deal with disassociating or "melting" in situ gas hydrate by heating the reservoir beyond the temperature of gas-hydrate formation, or decreasing the reservoir pressure below hydrate equilibrium. The pace of energy-related gas hydrate assessment projects has accelerated over the past several years. The Indian National Gas Hydrate Program Expedition 01 was designed to study the gas-hydrate occurrences off the Indian Peninsula and along the Andaman convergent margin with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings. During Indian National Gas Hydrate Program Expedition 01, dedicated gas-hydrate coring, drilling, and downhole logging operations were conducted from 28 April 2006 to 19 August 2006.

We performed a 4-variable parametric analysis of the AD-SOFC system in order to determine the optimal design operation conditions, depending on the objective function of interest We present results on the exergy efficiency (%), power normalized capital cost (kW super(-1)), and the internal rate of return on investment, IRR, (% yr super(-1)) as a function of the current density, the stack pressure, the fuel utilization, and the total air stoichiometric ratio. To the authors' knowledge, this is the first AD-SOFC paper to include the cost of the AD when conducting economic optimization of the AD-SOFC plant. Our calculations show that adding a new AD-SOFC system to an existing waste water treatment (WWT) plant could yield positives values of IRR at today's average electricity prices and could significantly out-compete other options for using biogas to generate electricity. AD-SOFC systems could likely convert WWT plants into net generators of electricity rather than net consumers of electricity while generating economically viable rates of return on investment if the costs of SOFC systems are within a factor of two of the DOE/SECA cost targets.

2016-097442 AB - The Indian monsoon drives seasonal changes in precipitation and weathering across India as well as circulation and productivity in the northern Indian Ocean. Variation in paleo-monsoon intensity and its effect on productivity and lithogenic fluxes is poorly constrained in the Bay of Bengal. In this paper, we present analysis of a sediment record from the offshore Mahanadi Basin recovered during the Indian National Gas Hydrate Program Expedition 01 (Site NGHP-01-19B). We reconstruct variation in biogenic and lithogenic components during the last 110 kyr using measurements of total organic carbon (TOC), total nitrogen (TN), TOC/TN, CaCO (sub 3) , biogenic silica (BSi), delta (super 13) TOC, delta (super 15) TN, bulk mineralogy from X-ray diffraction, bulk and lithogenic grain size distribution, magnetic susceptibility, bulk density, and Ca, Br, and Zr/Rb from x-ray fluorescence (XRF). The mass-accumulation rate (MAR) of CaCO (sub 3) , a function of marine productivity, drastically increased between 70 and 10 ka and is correlated to previously-documented elevated Asian dust fluxes and increased Bay of Bengal salinity during a weakened southwest monsoon. Decreased freshwater input over this period likely diminished stratification, allowing for increased mixing and nutrient availability, thus enhancing productivity despite weaker southwest monsoon winds. The MAR of lithogenic material is highest during the Holocene suggesting that sediment supply driven by monsoon intensity is a stronger control on margin sedimentation than sea level at the Mahanadi Basin. Over the entire record, magnetic susceptibility and XRF Zr/Rb are strongly correlated with CaCO (sub 3) , suggesting higher primary mineral input under a weakened southwest monsoon. TOC/TN and delta (super 13) TOC also increase under glacial conditions, suggesting higher relative input of terrestrial C4 organic matter. These results highlight the Mahanadi Basin as a supply-dominated margin where terrigenous sedimentation is strongly influenced by monsoon intensity, and that productivity is limited by variation in monsoon-driven stratification on glacial-interglacial timescales rather than a direct response to monsoon winds.

In hydrate-bearing sediments, the potential for sampling disturbance may be aggravated, since pressure and temperature changes can lead to hydrate dissociation and gas exsolution. Pressure core technology attempts to recover and characterize hydrate-bearing sediments while preserving them under in situ pressure and temperature conditions, which is an essential requirement to assess the mechanical, physical, chemical, and biological properties of natural hydrate-bearing sediments. Previous studies on near-surface sampling effects are extended in this study to evaluate additional sampling disturbances relevant to hydrate-bearing sediments: (1) hydrate dissociation due to mechanical extension, (2) negative pore pressure generation during unloading (Mandel-Cryer effect), (3) secondary hydrate formation, (4) changes in hydrate mass as a function of changes in pressure and temperature within the stability field, (5) hydrate anomalous preservation and its benefits for pressure core handling and testing, and (6) relaxation/aging following sampling. Results provide valuable insight to sampler design, coring and operation procedures, high pressure chamber design, and pressure core testing techniques. Abstract Copyright (2014) Elsevier, B.V.

The stratigraphic record at Site 17A in the Andaman Sea, eastern Indian Ocean, illustrates the need to better understand the role pore-scale phenomena play in the distribution and presence of marine gas hydrates in a variety of subsurface settings. In this paper we integrate field-generated datasets with newly acquired sedimentology, physical property, imaging and geochemical data with mineral saturation and ion activity products of key mineral phases such as amorphous silica and calcite, to document the presence and nature of secondary precipitates that contributed to anomalous porosity preservation at Site 17A in the Andaman Sea. This study demonstrates the importance of grain-scale subsurface heterogeneities in controlling the occurrence and distribution of concentrated gas hydrate accumulations in marine sediments, and document the importance that increased permeability and enhanced porosity play in supporting gas concentrations sufficient to support gas hydrate formation. The grain scale relationships between porosity, permeability, and gas hydrate saturation documented at Site 17A likely offer insights into what may control the occurrence and distribution of gas hydrate in other sedimentary settings.

Their hydraulic properties are critical parameters for determining fluid migration and leakage, and are subject to alterations when exposed to reactive flow, e.g. CO2-acidified brine in the case of carbon storage. Our previous studies have shown how mineral heterogeneity could lead to increased roughness that mitigates the increase in fracture permeability. This study shows that, even in rocks with mineral homogeneity, fracture geometry is subject to complex alterations. In this presentation, we report an experimental study of CO2-acidified brine in fractured Indiana Limestone, with comprehensive characterization of effluent chemistry analyzed by ICP-OES, and 3D geometry evolution using micro-computed topography (xCT). Significant carbonate dissolution was observed but the reaction extent revealed by the effluent chemistry was less than what was predicted by simple reaction transport models. xCT imaging revealed the formation of wormhole channels in the fracture, and the channels grew larger downstream and more prominent over time. Using the fracture geometries derived from the xCT images, we simulated the flow field and inferred the evolution of fracture hydraulic properties. To interpret the process of wormholing and its impacts on fracture hydraulic properties, we used reactive transport modeling to simulate the interplay between fracture geometry, fluid flow and geochemical reactions. Our simulations predicted that wormholes were formed in fractures with initial roughness representative of natural subsurface systems. The presence of wormholes caused a disproportionately larger permeability increase than would be expected given the extent of volume change.

In reactive fractures, mineral reactions also can alter fracture properties locally, therefore leading to evolving spatial heterogeneity. Here we use two-dimensional (2D) reactive transport modeling to 1) understand the evolving spatial heterogeneity due to the preferential dissolution of carbonate and 2) quantify the dependence of calcite dissolution on characteristics of spatial heterogeneity, including fracture roughness (i.e., aperture standard derivation, surface parameter and fractal dimension), flow connectivity (i.e., ratio of effective permeability k (sub eff) over geometric mean of local permeability k (sub G) ), and transport connectivity indicators (e.g., ratio of late 5% arrival time t (sub late5%) over average arrival time t (sub ave) ). The fractured core samples from Brady's Hot Springs geothermal field are composed of primarily carbonate, clay, and quartz. The computational domains were set up using fracture images obtained from CT scanning at the resolution of 31.6 mu m. The two samples have similar initial average aperture, porosity, permeability, and mineralogical composition. They differ in the spatial patterns: one has narrow large-aperture zones distributed widely (AD sample); the other has a major large-aperture zone in the middle of the sample (AC sample). Simulation results show that highly connected flow path forms quickly in the AD sample, leading to an increase of average chemical aperture, effective permeability, and flow velocity by five times after 75 days of injecting salt water. In contrast, these properties remain constant in the AC sample. Other parameters that quantitatively characterize the spatial heterogeneity, including connectivity and the tail slope of the breakthrough curves, also change dramatically, indicating major alteration in fracture properties due to calcite dissolution.

Wellbore alteration has been observed under supercritical CO (sub 2) exposure condition in previous experimental and field studies. One such study also showed that a reduction in both tensile and compressive strength when specimens were exposed to CO2-O (sub 2) gases at 50 degrees C and 85 degrees C as compared to specimens only exposed to CO (sub 2) gases; secondary mineral precipitation (SMP) and high temperature was speculated as the causes. In this study, experiments were designed to justify how different variables influenced SMP, and to quantify its effect on mechanical properties of Class H Portland cement. Chemical and mechanical alterations of Class H cement were investigated to verify the impact of SMP during this process. Cement prisms were investigated under different scenarios including influence of brine composition (simulated Mt. Simon basin), high temperature (up to 85 degrees C); high pressure (up to 4200 psi); CO (sub 2) sequestration; CO (sub 2) -O (sub 2) co-sequestration. Modulus of rupture and compressive strength of the cement prisms were tested under each scenario and several exposure durations. Initial results indicated that high temperature and synthetic brine composition had a negative influence on compressive strength. Pore solution analysis was conducted to examine the ionic exchange and geochemical alteration between the cement and brine. Specimens decreased in sodium and potassium, significantly increased in calcium, and slightly increased in sulfate after CO (sub 2) injected into system. Scanning electronic microscopy visually identified SMP and the alteration depth of specimens exposed to CO (sub 2) gas and CO (sub 2) -O (sub 2) gases with time of exposure, respectively. The predicted degree of SMP, change of pore solution, and mechanic strength based on temperature, pressure, brine composition, and gas exposure conditions will be presented.

In many oil and gas well applications, the most common proppant materials are sand, ceramic particles, resin-coated sands, glass beads or even walnut shells. More dense proppants require additives to create viscous fluids which can transport them further along wells and into fractures, but are generally preferred over neutrally buoyant options due to their increased strength. Currently, proppant strength and generation of broken fragments ("fines") is analyzed via a standardized crush test between parallel plates. To augment this type of information, we present here the results of various experiments involving resin-coated proppants held at increasing pressures in fractured samples of Marcellus shale. The shale/proppant samples were imaged continuously with an industrial tomography scanner during pressurization up to 10,000 psi. This technique allows for in situ characterization of fracture/proppant interactions and fracture void volume and average aperture with varying confining pressures.

Produced water from oil wells tapping a carbonate-hosted reservoir at an active EOR site in the Permian Basin of Texas both before and after injection were sampled to evaluate geochemical and isotopic changes associated with water-rock-CO2 interaction. Produced waters from the carbonate reservoir rock are Na-Cl brines with TDS levels of 16.5-34 g/L and detectable H2S. These brines are potentially diluted with shallow groundwater from earlier EOR water flooding. Initial lithium isotope data (delta 7Li) from pre-injection produced water in the EOR field fall within the range of Gulf of Mexico Coastal sedimentary basin and Appalachian basin values (Macpherson et al., 2014, Geofluids, doi: 10.1111/gfl.12084). Pre-injection produced water 87Sr/86Sr ratios (0.70788-0.70795) are consistent with mid-late Permian seawater/carbonate. CO2 injection took place in October 2013, and four of the wells sampled in May 2014 showed CO2 breakthrough. Preliminary comparison of pre- and post-injection produced waters indicates no significant changes in the major inorganic constituents following breakthrough, other than a possible drop in K concentration. Trace element and isotope data from pre- and post-breakthrough wells are currently being evaluated and will be presented.

As such, an understanding of what influences fracture permeability is critically important to describing sub-surface flows. Numerous studies have been reported which illustrate the importance of rock fracture geometry on the permeability of fractures, in particular the influence of zero aperture locations within the fracture aperture. increasing the tortuosity of flow through a fracture and subsequently decreasing the fracture permeability. Fractures and faults can shear due to increased transverse stresses, or an increase of fluid pressure within a fracture reducing the effective forces stopping fracture slippage. This behavior has been widely observed in many seismic events. How small scale shearing events influence the permeability of fracture is not well known though, as few experimental tests have been performed that enable the dynamic change in a fractured rock position while simultaneously measuring the permeability across the fracture. This talk describes resent research at the National Energy Technology Laboratory in Morgantown, West Virginia where fractured rock cores have been experimentally sheared and the permeability through the fracture has been measured. In addition, these fractured cores were imaged with computed tomography scanning to understand what geometric alterations to the fracture structure influence the shearing induced changes to fracture permeability. Both shale and sandstone fractured cores have been evaluated with this unique core flow apparatus, and relationships between the shearing distance, rock type, and initial fracture geometry are being developed to provide guidance on understanding and modeling sheared fracture permeability changes in CO2 sequestration and other sub-surface activities.

The hydraulic aperture of a fracture quantifies how much fluid can be transported through a fracture, similarly to how permeability describes fluid flow through porous media. The advantage of defining the fracture hydraulic aperture as opposed to permeability, is that this property can be easily scaled up to fracture reservoir simulators. Many parameters affect the hydraulic aperture, however, including the fracture roughness, the physical aperture distribution, and the tortuosity of flow paths within the fracture.The computed tomography (CT) and flow facility at NETL has conducted an analysis of the changes in both physical and hydraulic aperture as fractures were subjected to varying external confining stresses. Changes in fracture geometry were tracked through the use of non-destructive CT imaging, allowing the determination of the physical aperture distribution, while hydraulic fracture apertures were derived from experimental fracture flow measurements. In order to evaluate the effects of fracture roughness and geometry, two fractures with different degrees of roughness were used. Tests were conducted with locally sourced shale. Experimental results show that the volume change in the fracture is a non-linear function of the confining pressure, and both physical and hydraulic apertures decrease rapidly as the fracture is first compressed.

A new critical state model was developed that incorporates the spatially mobilized plane (SMP) concept, which has been proven effective in modeling mechanical behavior of sands. While this new model was built on the basic constructs of the critical state model, important enhancements were introduced. The model adopted the t-stress concept, which defined the normal and shear stress on the SMP, in describing the plastic behavior of the soil. In this connection the versatile Matsuoka-Nakai yield criterion was also employed, which defined the general three dimensional yield behavior. The resulting constitutive law was associated in the t-stress space, but became non-associated in the conventional p-q stress space as it should be for sands. The model also introduced a generalized degree of hydrate saturation concept that was modified from the pioneering work of the Cambridge group. The model gives stress change when the sands are subjected to straining, and/or to hydrate saturation changes. The performance of the model has been found satisfactory using data from laboratory triaxial tests on reconstituted samples and core samples taken from Nankai Trough, Japan. The model has been implemented into FLAC3D. A coupling example with the multiphase flow code, TOUGH+, is presented which simulates the mechanical behavior of a sample when the surrounding temperature has been raised, and the hydrate undergoes state change and no longer resides in the stability zone.

The interpretation of the REE content in a gas-bearing black shale deposited in a marine environment must therefore take into account the paleoredox conditions of deposition as well as any diagenetic remobilization and authigenic mineral formation. We analyzed 15 samples from a core of the Marcellus Shale (Whipkey ST1, Greene Co., PA) for REEs, TOC, gas-producing potential, trace metal content, and carbon isotopes of organic matter in order to determine the REE systematics of a black shale currently undergoing shale gas development. We also conducted a series of sequential leaching experiments targeting the phosphatic fractions in order to evaluate the dominant host phase of REEs in a black shale. Knowledge of the REE system in the Marcellus black shale will allow us to evaluate potential REE release and behavior during hydraulic fracturing operations. Total REE content of the Whipkey ST1 core ranged from 65-185 mu g/g and we observed three distinct REE shale-normalized patterns: middle-REE enrichment (MREE/MREE* nearly equal 2) with heavy-REE enrichment (HREE/LREE approximately 1.8-2), flat patterns, and a linear enrichment towards the heavy-REE (HREE/LREE approximately 1.5-2.5). The MREE enrichment occurred in the high carbonate samples of the Stafford Member overlying the Marcellus Formation. The HREE enrichment occurred in the Union Springs Member of the Marcellus Formation, corresponding to a high TOC peak (TOC approximately 4.6-6.2 wt%) and moderate carbonate levels (CaCO3 approximately 4-53 wt%). Results from the sequential leaching experiments suggest that the dominant host of the REEs is the organic fraction of the black shale and that the detrital and authigenic fractions have characteristic MREE enrichments. We present our conclusions on the impact of depositional setting and diagenetic remobilization and authigenic mineral formation on the REE system in the Marcellus Shale.

Here we present evidence for microbial activity in HF production fluids. Fluids collected from a Marcellus shale HF well were supplemented with 13C-labeled carbon sources and 15N-labeled ammonium at 25 degrees C under aerobic or anaerobic conditions. Samples were analyzed for 13C and 15N incorporation at sub-micrometer scale by ion imaging with the JAMSTEC NanoSIMS to determine percent carbon and nitrogen assimilation in individual cells. Headspace CO2 and CH4 were analyzed for 13C enrichment using irm-GC/MS. At 32 days incubation carbon assimilation was observed in samples containing 1 mM 13C-labeled glucose under aerobic and anaerobic conditions with a maximum of 10.4 and 6.5% total carbon, respectively. Nitrogen assimilation of 15N ammonium observed in these samples were 0.3 and 0.8% of total nitrogen, respectively. Head space gas analysis showed 13C enrichment in CH4 in anaerobic samples incubated with 1 mM 13C-labeled bicarbonate (2227 ppm) or methanol (98943 ppm). Lesser 13C enrichment of CO2 was observed in anaerobic samples containing 1 mM 13C-labeled acetate (13.7 ppm), methanol (29.9 ppm) or glucose (85.4 ppm). These results indicate metabolic activity and diversity in microbial communities present in HF flowback fluids. The assimilation of 13C-labeled glucose demonstrates the production of biomass, a critical part of cell replication. The production of 13CO2 and 13CH4 demonstrate microbial metabolism in the forms of respiration and methanogenesis, respectively. Methanogenesis additionally indicates the presence of an active archaeal community. This research shows that HF production fluid chemistry does not entirely inhibit microbial activity or growth and encourages further research regarding biogeochemical processes occurring in Marcellus shale HF wells. Biogeochemical activity may impact the efficacy of HF and natural gas production as well as the chemistry of produced fluids which have become an environmental and public health concern.

However, experimental studies to determine fitting parameters of those equations are not available in the literature. The objective of this research is to obtain reliable parameters for capillary pressure functions and relative permeability equations applicable to hydrate dissociation and gas production. In order to achieve this goal, (1) micro X-ray Computer Tomography (CT) is used to scan the specimen under 10 MPa effective stress, (2) a pore network model is extracted from the CT image, (3) hydrate dissociation and gas expansion are simulated in the pore network model, (4) the parameters for the van Genuchten-type soil water characteristic curve and relative permeability equation during gas expansion are suggested. The research outcome will enhance the ability of numerical simulators to predict gas and water production rate.

Cores were subsequently stored at approximately 20 MPa and approximately 5 degrees C, which maintained hydrate in the cores within stability conditions. Pressure core physical properties were measured at 10 MPa and approximately 6 degrees C, also within the methane hydrate stability field, using the IPTC and other Pressure Core Characterization Tools (PCCTs). Discrete IPTC measurements were carried out in strata ranging from silty sands to clayey silts within the turbidite sequences recovered in the cores. As expected, hydrate saturations were greatest in more permeable coarser-grained layers. Key results include: 1) Where hydrate saturation exceeded 40% in sandy sediments, the gas hydrate binds sediment grains within the matrix. The pressure core analyses yielded nearly in situ mechanical properties despite the absence of effective stress in the IPTC. 2) In adjacent fine-grained sediment (hydrate saturation <15%), hydrate did not significantly bind the sediment. IPTC results in these locations were consistent with the zero effective-stress limit of comparable measurements made in PCCT devices that are designed to restore the specimen's in situ effective stress. In sand-rich intervals with high gas hydrate saturations, the measured compressional and shear wave velocities suggest that hydrate acts as a homogeneously-distributed, load-bearing member of the bulk sediment. The sands with high gas hydrate saturations were prone to fracturing (brittle failure) during insertion of the cone penetrometer and electrical conductivity probes. Authors would like to express their sincere appreciation to MH21 and the Ministry of Economy, Trade and Industry for permitting this work to be disclosed at the 2014 Fall AGU meeting.

In addition, contamination events are often elusive. As a result, it is often challenging to pinpoint the contamination of natural waters by specific types of water sources. The strontium isotope ratio R87Sr, defined as 87Sr/86Sr, has shown promise in discerning contamination from different types of wastewaters related to Marcellus Shale development. The R87Sr of potential end members, including Marcellus shale produced water (0.710-0.712) and Upper Devonian/Lower Mississippian formation brine (0.720-0.721), have been shown to be distinct from those in natural waters. Here we use reactive transport modeling (CrunchFlow) to understand key process and factors that govern the evolution of R87Sr, and the conditions under which we can discern contamination sources in natural water systems. Simulation results show that ion exchange reaction plays an important role in the evolution of R87Sr while release rate has a relatively minor impact on R87Sr evolution. Even with large dilution factor where the volumetric flow rate of natural waters is orders of magnitude higher than the release rates of contamination source water, the R87Sr is still sensitive to different types of source contamination waters. Insights gained here suggest that strontium isotopes can potentially be used as a tracers for different type of water contamination. The modeling tool developed can offer a powerful tool for understanding, predicting, monitoring of natural water contamination.

For sediments containing the same amount of hydrates, their overall physical properties may vary several orders of magnitude depending on hydrate pore habit. We investigate the interplay among hydrate formation methods, hydrate pore habits, and fundamental physical properties of hydrate bearing sediments. We have developed a new method to synthesize noncementing hydrate in sands, a multi-properties characterization chamber to test the hydrate bearing sediments, and pore network models to simulate fluid flow processes in hydrate bearing sediments. We have found that (1) the growth pattern of hydrate crystal in the pore spaces of water saturated sediments is dominated by the relative magnitude of the capillary force (between hydrate crystal and pore fluid) and the skeleton force, which will result in pore-filling or grain-displacing type of hydrate pore character; (2) the existing capillary tube models of water permeability in hydrate bearing sediments are sensitive to pore geometry and hydrate pore habit; and (3) preliminary CT results suggest that hydrate nucleation in partially water saturated sands tends to agglomerate in patches, rather than in an uniformly-distributed contact-cementing morphology. Additional CT results with a small amount of fines (5 wt%) and visualization via micro-CT of hydrate pore habits in sediments using different hydrate formation methods will be discussed.

observations and new insights for hydrate film models AN - 1629947488; 2014-097293 AB - Predicting the fate of subsea hydrocarbon gases escaping into seawater is complicated by potential formation of hydrate on rising bubbles that can enhance their survival in the water column, allowing gas to reach shallower depths and the atmosphere. The precise nature and influence of hydrate coatings on bubble hydrodynamics and dissolution is largely unknown. Here we present high-definition, experimental observations of complex surficial mechanisms governing methane bubble hydrate formation and dissociation during transit of a simulated oceanic water column that reveal a temporal progression of deep-sea controlling mechanisms. Synergistic feedbacks between bubble hydrodynamics, hydrate morphology, and coverage characteristics were discovered. Morphological changes on the bubble surface appear analogous to macroscale, sea ice processes, presenting new mechanistic insights. An inverse linear relationship between hydrate coverage and bubble dissolution rate is indicated. Understanding and incorporating these phenomena into bubble and bubble plume models will be necessary to accurately predict global greenhouse gas budgets for warming ocean scenarios and hydrocarbon transport from anthropogenic or natural deep-sea eruptions.

AN - 1560578686; 24494801 AB - The use of atomistic Kinetic Monte Carlo method was explored to examine the influence of sulfur poisoning on CO adsorption on Pd(100) surface. The model explicitly incorporates key elementary processes such as CO adsorption and CO desorption including diffusion of surface CO and S species. Relevant energetic and kinetic parameters were derived using information calculated from density functional theory as a starting point. Kinetic Monte Carlo simulation was performed to determine relevant observables such as CO saturation coverage as a function of amount of preadsorbed sulfur and to predict temperature programmed desorption spectra.

A mobile, autonomous air quality monitoring laboratory was constructed to collect measurements of ambient concentrations of pollutants associated with oil and natural gas E&P activities. This air-monitoring laboratory was deployed to the Allegheny National Forest (ANF) in northwestern Pennsylvania for a campaign that resulted in the collection of approximately 7 months of data split between three monitoring locations between July 2010 and June 2011. The three monitoring locations were the Kane Experimental Forest (KEF) area in Elk County, which is downwind of the Sackett oilfield; the Bradford Ranger Station (BRS) in McKean County, which is downwind of a large area of historic oil and gas productivity; and the U.S. Forest Service Hearts Content campground (HC) in Warren County, which is in an area relatively unimpacted by oil and gas development and which therefore yielded background pollutant concentrations in the ANF. Concentrations of criteria pollutants ozone and NO sub(2) did not vary significantly from site to site; averages were below National Ambient Air Quality Standards. Concentrations of volatile organic compounds (VOCs) associated with oil and natural gas (ethane, propane, butane, pentane) were highly correlated. Applying the conditional probability function (CPF) to the ethane data yielded most probable directions of the sources that were coincident with known location of existing wells and activity. Differences between the two impacted and one background site were difficult to discern, suggesting the that the monitoring laboratory was a great enough distance downwind of active areas to allow for sufficient dispersion with background air such that the localized plumes were not detected.

This inherently random process often involves long induction times particularly in quiescent conditions. An experimental study was conducted to explore the kinetics of hydrate formation in the presence of mineral grains and when subjected to mechanical agitation. Results show that tetrahydrofuran THF hydrate nucleation is facilitated in the presence of most minerals, and induction times are a function of mineralogy and surface characteristics. While mechanical vibration does not suppress the inherent stochastic nature of nucleation, mechanical agitation triggers nucleation when the imposed acceleration exceeds 10m/s2.

Most geochemical studies on CO (sub 2) storage in saline formations are focused on the interactions of pure CO (sub 2) and do not consider the potential impacts of contaminants such as SO (sub 2) found in typical post-composition flue gas streams. This paper reports on results of a combined CO (sub 2) -co-contaminant-brine-rock experimental and a simple modeling study of the potential impact of flue gas contaminants on saline formations. Chemical reactions of the sandstone from Mount Simon formation exposed to CO (sub 2) mixed with other gas species under sequestration conditions were studied (i.e. solid material -- representative Mount Simon sandstone; liquid -- synthetic Illinois Basin brine; T and P -- 50 degrees C, 110 bar; gas composition -- 1% SO (sub 2) , 4% O (sub 2) , 95% CO (sub 2) ). The experimental study indicates that the co-injection of 1% SO (sub 2) would lead to substantially reduced brine pH due to the formation of sulfuric acid and the formation of bassanite (major) and anhydrites. Preliminary equilibrium computational modeling yielded similar results. Abstract Copyright (2010), John Wiley & Sons, Ltd.

Here we investigate the relationship between apparent water permeability (k') and hydrate saturation (S (sub h) ), accounting for hydrate pore-scale growth habit and meso-scale heterogeneity. Results from capillary tube models rely on cross-sectional tube shapes and hydrate pore habits, thus are appropriate only for sediments with uniform hydrate distribution and known hydrate pore character. Given our pore network modeling results showing that accumulating hydrate in sediments decreases sediment porosity and increases hydraulic tortuosity, we propose a modified Kozeny-Carman model to characterize water permeability in hydrate-bearing sediments. This model agrees well with experimental results and can be easily implemented in reservoir simulators with no empirical variables other than S (sub h) . Results are also relevant to flow through other natural sediments that undergo diagenesis, salt precipitation, or bio-clogging. Abstract Copyright (2014), . American Geophysical Union.

National attention related to CBNG development has focused on produced water management, which is the single largest cost for on-shore domestic producers. Low-cost treatment technologies allow operators to reduce their disposal costs, provide treated water for beneficial use, and stimulate oil and gas production by small operators. Subsurface drip irrigation (SDI) systems are one potential treatment option that allows for increased CBNG production by providing a beneficial use for the produced water in farmland irrigation. Water management practices in the development of CBNG in Wyoming have been aided by integrated geophysical, geochemical, and hydrologic studies of both the disposal and utilization of water. The U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) and the U.S. Geological Survey (USGS) have utilized multi-frequency airborne, ground, and borehole electromagnetic (EM) and ground resistivity methods to characterize the near-surface hydrogeology in areas of produced water disposal. These surveys provide near-surface EM data that can be compared with results of previous surveys to monitor changes in soils and local hydrology over time as the produced water is discharged through SDI. The focus of this investigation is the Headgate Draw SDI site, situated adjacent to the Powder River near the confluence of a major tributary, Crazy Woman Creek, in Johnson County, Wyoming. The SDI system was installed during the summer of 2008 and began operation in October of 2008. Ground, borehole, and helicopter electromagnetic (HEM) conductivity surveys were conducted at the site prior to the installation of the SDI system. After the installation of the subsurface drip irrigation system, ground EM surveys have been performed quarterly (weather permitting). The geophysical surveys map the heterogeneity of the near-surface geology and hydrology of the study area. The geophysical data are consistent between surveys using different techniques and between surveys carried out at different times from 2007 through 2011. This paper summarizes geophysical results from the 4-year monitoring study of the SDI system. Abstract Copyright (2014) Elsevier, B.V.

These factors are all important considerations for developing production and water management strategies. Produced water ranges from nearly potable sodium-bicarbonate water to hypersaline sodium-chloride brine. The hydrodynamic framework of the basin is dominated by structurally controlled fresh-water plumes that formed by meteoric recharge along the southeastern margin of the basin. The produced water contains significant quantities of hydrocarbons and nitrogen compounds, and the produced gas appears to be of mixed thermogenic-biogenic origin. Late-stage microbial methanogenesis began following unroofing of the basin, and stable isotopes in the produced gas and in mineral cements indicate that late-stage methanogenesis occurred along a CO (sub 2) -reduction metabolic pathway. Hydrocarbons, as well as small amounts of nitrate in the formation water, probably helped nourish the microbial consortia, which were apparently active in fresh to hypersaline water. The produced water contains NH (sub 4) (super +) and NH (sub 3) , which correlate strongly with brine concentration and are interpreted to be derived from silicate minerals. Denitrification reactions may have generated some N (sub 2) , which is the only major impurity in the coalbed gas. Carbon dioxide is a minor component of the produced gas, but significant quantities are dissolved in the formation water. Degradation of organic compounds, augmented by deionization of NH (sub 4) (super +) , may have been the principal sources of hydrogen facilitating late-stage CO (sub 2) reduction.

Natural gas is mainly being produced from Devonian shales in the Horn River Basin and from the Triassic Montney shales and siltstones, both located in northeastern British Columbia and, to a lesser extent, in the Devonian Duvernay Formation in Alberta (western Canada). Other shales with natural gas potential are currently being evaluated, including the Upper Ordovician Utica Shale in southern Quebec and the Mississippian Frederick Brook Shale in New Brunswick (eastern Canada). This paper describes the status of shale gas exploration and production in Canada, including discussions on geological contexts of the main shale formations containing natural gas, water use for hydraulic fracturing, the types of hydraulic fracturing, public concerns and on-going research efforts.

Since groundwater decontamination is difficult, or nearly impossible, it is essential to evaluate exploration and production conditions that would prevent or at least minimize risks of groundwater contamination. The current consensus in recent literature is that these risks are primarily related to engineering issues, including casing integrity and surface activities, such as truck traffic (equipment and fluid haulage), waste management (mainly drill cuttings), and water storage and treatment when hydraulic fracturing is utilized. Concerns have also been raised with respect to groundwater contamination that could result from potential fracture or fault interconnections between the shale unit and surficial aquifers, which would allow fracturing fluids and methane to reach the surface away from the wellbore. Despite the fact that groundwater resources are relatively well characterized in some regions, there is currently no recognized method to evaluate the vulnerability or risks to aquifers resulting from hydrocarbon industry operations carried out at great depths. This paper focuses on the Utica Shale of the St. Lawrence Platform (Quebec), where an environmental study aiming to evaluate potential risks for aquifers related to shale gas development has been initiated. To provide the context of these research efforts, this paper describes the regional tectono-stratigraphic evolution and current stress regime of the Cambrian-Ordovician St. Lawrence Platform, as well as the Utica Shale internal stratigraphy, mineralogy and thermal maturation. Then, the hydrogeological context of the St. Lawrence Platform is discussed. Finally, the methodology for this environmental study, based on geological, geophysical, geomechanical, hydrogeological and geochemical data, is presented. Abstract Copyright (2014) Elsevier, B.V.

Hydraulic fracturing applied to vertical tight sand and coal bed methane wells achieved some degree of success during a period of high energy prices in the early 1980s, but shale gas remained largely untapped until the late 1990s with the application of directional drilling, a mature technology adapted from deepwater offshore platforms that allowed horizontal wells to penetrate kilometers of organic-rich shale, and staged hydraulic fracturing, which created high permeability flowpaths from the horizontal wells into a much greater volume of the target formations than previous completion methods. These new engineering techniques opened up vast unconventional natural gas and oil reserves, but also raised concerns about potential environmental impacts. These include short-term and long-term impacts to air and water quality from rig operations, potential migration of gas, fluids and chemicals through the ground, and effects on small watersheds and landscapes from roads, pads and other surface structures. Engineering risk assessment commonly uses integrated assessment models (IAMs), which define sources of risk from features, events and processes. The risk from each system element is assessed using high-fidelity models. Output from these is simplified into reduced-order models, so that a large, integrated site performance assessment can be run using the IAM. The technique has been applied to engineered systems in geologic settings for sequestering carbon dioxide, and it is also applicable to shale gas, albeit with some modifications of the various system elements. Preliminary findings indicate that shale gas well drilling and hydraulic fracturing techniques are generally safe when properly applied. Incident reports recorded by state environmental agencies suggest that human error resulting from the disregard of prescribed practices is the greatest cause of environmental incidents. This can only be addressed through education, regulations and enforcement. Abstract Copyright (2014) Elsevier, B.V.

Shallow coal seams regularly contain abundant resources of biogenic gas; as such water associated with biogenic gas in these coal beds is isotopically distinct from other waters. The production of gas from coal beds requires the removal of large volumes of produced water. Thus a method of discerning coalbed reservoir water from other natural waters (surface and groundwater) is important to both the coalbed natural gas (CBNG) industry and associated environmental and regulatory agencies. Although isotopic tracers have been employed to identify coalbed natural gas produced waters, the isotopic variability within the reservoir has not been documented and explained. In this study, we present the isotopic compositions of dissolved inorganic carbon, oxygen and hydrogen for water produced from 197 CBNG wells in the Powder River Basin of Wyoming and Montana. This extensive database allows us to distinguish variations in isotopic compositions that may occur by multiple processes. These include variations that identify efficient dewatering of coal beds, variations characterizing incomplete hydraulic isolation of coal beds from adjacent strata and the subsequent mixing of groundwaters, variations related to well completion design, and variations associated with geochemical and biogenic processes that occur along groundwater flow paths. These data suggest that little change in delta (super 13) C (sub DIC) occurs within the reservoir as a result of water and gas production; thus, the carbon isotopic composition informs other processes within the reservoir unrelated to coalbed natural gas recovery. The delta (super 13) C (sub DIC) and delta D of groundwater vary along flow-path across the basin, reflecting different methanogenic pathways that are associated with different isotopic fractionations, and the pathways that dominate in different areas within the basin. In areas where several producing coal seams are present, the delta (super 13) C (sub DIC) and delta D of produced waters from each seam are distinct. Therefore on a local scale, the isotopic composition of produced water can identify the particular coal seam from which water and gas are withdrawn. The methods and results presented in this case study provide examples that illustrate how water quality and isotopic data can be used to determine the hydraulic connectivity between coal and non-coal strata, identify and quantify water from individual coal horizons, as well as predict and understand the isotopic variability of the reservoir.

Formations analyzed include the Antrim, Bakken, Barnett, Eagle Ford, Haynesville, Marcellus, New Albany, Utica and Woodford. These mineralogic and trace element data can be used to assess the potential for environmental impacts during hydraulic fracturing. Impacts addressed in this study include: 1) the potential for acid rock drainage generation during gas shale weathering, 2) the distribution of trace elements in gas shales and comparison with regulatory guidelines, and 3) the implications for environmental management of well cuttings. The use of the mineralogic data to assess the fracability of the gas shales is also considered. Compilations of the mineralogy and geochemistry of gas shales can be a valuable resource for managing real and perceived environmental problems associated with their exploitation. Comprehensive environmental assessment to fully address these issues, in addition to other potential environmental impacts, will require collection and collation of additional data on the mineralogy and trace element geochemistry of gas and other hydrocarbon producing shales.

The Marcellus play in the northeastern U.S.A. documents how fast this technology developed: the number of unconventional Marcellus wells in Pennsylvania (PA) increased from 8 in 2005 to approximately 7234 today. Publicly available databases in PA show only rare evidence of contamination of surface and groundwaters. This could document that incidents that impact PA waters have been relatively rare and that contaminants were quickly diluted. However, firm conclusions are hampered by i) the lack of information about location and timing of incidents; ii) the tendency to not release water quality data related to specific incidents due to liability or confidentiality agreements; iii) the sparseness of sample and sensor data for the analytes of interest; iv) the presence of pre-existing water impairments that make it difficult to determine potential impacts from shale-gas activity; and v) the fact that sensors can malfunction or drift. Although the monitoring data available to assess contamination events in PA are limited, the state manages an online database of violations. Overall, one fifth of gas wells drilled were given at least one non-administrative notice of violation (NOV) from the PA regulator. Through March 2013, 3.4% of gas wells were issued NOVs for well construction issues and 0.24% of gas wells received NOVs related to methane migration into groundwater. Between 2008 and 2012, 161 of the approximately 1000 complaints received by the state described contamination that implicated oil or gas activity: natural gas was reported for 56% and brine salt components for 14% of the properties. Six percent of the properties were impacted by sediments, turbidity, and/or drill cuttings. Most of the sites of groundwater contamination with methane and/or salt components were in previously glaciated northern PA where fracture flow sometimes allows long distance fluid transport. No cases of subsurface transport of fracking or flowback fluids into water supplies were documented. If Marcellus-related flowback/production waters did enter surface or groundwaters, the most likely contaminants to be detected would be Na, Ca, and Cl, but those elements are already common in natural waters. The most Marcellus-specific "fingerprint" elements are Sr, Ba, and Br. For example, variable Br concentrations measured in southwestern PA streams were attributed to permitted release of wastewaters from unconventional shale gas wells into PA streams through municipal or industrial wastewater treatment plants before 2011. Discharge has now been discontinued except for brines from a few plants still permitted to discharge conventional oil/gas brines after treatment. Overall, drinking water supply problems determined by the regulator to implicate oil/gas activities peaked in frequency in 2010 while spill rates increased through 2012. Although many minor violations and temporary problems have been reported, the picture that emerges from PA is that the fast shale-gas start may have led to relatively few environmental incidents of significant impact compared to wells drilled; however, the impacts remain difficult to assess due to the lack of transparent and accessible data.

Since 2008, a rapid increase in Marcellus Shale gas production has led to a commensurate rise in associated wastewater while generation of produced water from conventional oil and gas activities has continued. In this study, we assess whether disposal practices from treatment of produced waters from both shale gas and conventional operations in Pennsylvania could result in the accumulation of associated alkali earth elements. The results from our 5 study sites indicate that there was no increase in concentrations of total Ra (Ra-226) and extractable Ba, Ca, Na, or Sr in fluvial sediments downstream of the discharge outfalls (p>0.05) of publicly owned treatment works (POTWs) and centralized waste treatment facilities (CWTs). However, the use of road spreading of brines from conventional oil and gas wells for deicing resulted in accumulation of Ra-226 (1.2X), and extractable Sr (3.0X), Ca (5.3X), and Na (6.2X) in soil and sediment proximal to roads (p<0.05). Although this study is an important initial assessment of the impacts of these disposal practices, more work is needed to consider the environmental consequences of produced waters management.

The chemistry of the returning fluid reflects the original composition of the injection water, mobilized constituents in the shale formation, and co-mingled formation waters liberated by hydraulic fracturing. Produced water from unconventional gas wells tapping the Middle Devonian Marcellus Formation is characterized by high total dissolved solids (TDS), including very high strontium concentrations. In this study, the strontium isotope composition ( (super 87) Sr/ (super 86) Sr) was measured in produced waters from four horizontally drilled, hydraulically fractured Marcellus shale gas wells in southwestern Pennsylvania, sampled from the first day after commencement of flowback to as much as 27 months later. The (super 87) Sr/ (super 86) Sr of the waters tended to change rapidly over the first few days of water return, and then approached (but did not reach) a constant range of values from 0.7113 to 0.7114, which appears to be characteristic of this part of the Marcellus play. In contrast, the concentration of Sr rose more slowly and appeared to hit a steady state value (up to 3000 mg/L) by the end of the first year. Taken together with results from earlier work, these data suggest mixing between injected frac fluid and high-TDS formation water, highly enriched in Sr, and isotopically relatively uniform throughout the Marcellus shale gas play. This brine could exist within porous lenses of organic matter in the shale, in pre-existing fractures within the shale, and/or originate from fluids that migrated from adjacent formations at some point during the post-depositional history of the basin.

Disposal of produced waters from gas extraction in coal and shale is an important environmental issue because of the large volumes of water involved and the variable quality of this water. Organic substances in produced water may be environmentally relevant as pollutants, but have been little studied. Results from five CBM plays and two gas shale plays (including the Marcellus Shale) show a myriad of organic chemicals present in the produced and formation water. Organic compound classes present in produced and formation water in CBM plays include: polycyclic aromatic hydrocarbons (PAHs), heterocyclic compounds, alkyl phenols, aromatic amines, alkyl aromatics (alkyl benzenes, alkyl biphenyls), long-chain fatty acids, and aliphatic hydrocarbons. Concentrations of individual compounds range from <1 to 100mu g/L, but total PAHs (the dominant compound class for most CBM samples) range from 50 to 100mu g/L. Total dissolved organic carbon (TOC) in CBM produced water is generally in the 1-4 mg/L range. Excursions from this general pattern in produced waters from individual wells arise from contaminants introduced by production activities (oils, grease, adhesives, etc.). Organic substances in produced and formation water from gas shale unimpacted by production chemicals have a similar range of compound classes as CBM produced water, and TOC levels of about 8 mg/L. However, produced water from the Marcellus Shale using hydraulic fracturing has TOC levels as high as 5500 mg/L and a range of added organic chemicals including, solvents, biocides, scale inhibitors, and other organic chemicals at levels of 1000s of mu g/L for individual compounds. Levels of these hydraulic fracturing chemicals and TOC decrease rapidly over the first 20 days of water recovery and some level of residual organic contaminants remain up to 250 days after hydraulic fracturing. Although the environmental impacts of the organics in produced water are not well defined, results suggest that care should be exercised in the disposal and release of produced waters containing these organic substances into the environment because of the potential toxicity of many of these substances.

These produced waters or brines must be treated and/or disposed and provide a daily challenge for operators and resource managers. Some elements of salts are regulated with water quality criteria established for the protection of aquatic wildlife, e.g. chloride (Cl (super -) ), which has an acute standard of 860 mg/L and a chronic standard of 230 mg/L. However, data for establishing such standards has only recently been studied for other components of produced water, such as bicarbonate (HCO (sub 3) (super -) ), which has acute median lethal concentrations (LC50s) ranging from 699 to >8000 mg/L and effects on chronic toxicity from 430 to 657 mg/L. While Cl (super -) is an ion of considerable importance in multiple geographical regions, knowledge about the effects of hardness (calcium and magnesium) on its toxicity and about mechanisms of toxicity is not well understood. A multiple-approach design that combines studies of both individuals and populations, conducted both in the laboratory and the field, was used to study toxic effects of bicarbonate (as NaHCO (sub 3) ). This approach allowed interpretations about mechanisms related to growth effects at the individual level that could affect populations in the wild. However, additional mechanistic data for HCO (sub 3) (super -) , related to the interactions of calcium (Ca (super 2+) ) precipitation at the microenvironment of the gill would dramatically increase the scientific knowledge base about how NaHCO (sub 3) might affect aquatic life. Studies of the effects of mixtures of multiple salts present in produced waters and more chronic effect studies would give a better picture of the overall potential toxicity of these ions. Organic constituents in hydraulic fracturing fluids, flowback waters, etc. are a concern because of their carcinogenic properties and this paper is not meant to minimize the importance of maintaining vigilance with respect to potential organic contamination.

Objectives of this research were to 1) examine the chemistry of CBNG produced water in outfalls and corresponding disposal ponds and 2) determine possible leaching of trace elements from the disposal pond sediments into shallow aquifers. The CBNG outfall water, disposal pond water, and sediment samples were collected from the Powder River Basin (PRB), WY during the summer months of 2006 to 2009. Water samples were analyzed for pH, major cations, anions, and trace elements. Geochemical analysis was performed using MINTEQA2 model to determine speciation, complexation, and mineral precipitation and dissolution processes to determine the mobility of trace elements in CBNG disposal ponds. Two types of SAR calculations were made: 1) practical SAR (SARp) was calculated based on Na (super +) , Ca (super 2+) , and Mg (super 2+) concentrations and 2) true SAR (SARt) was calculated based on MINTEQA2 calculated activity of Na (super +) , Ca (super 2+) , and Mg (super 2+) . Sediment samples were analyzed for trace elements using toxicity characteristic leaching procedure (TCLP) to predict potential mobility of trace elements into the shallow aquifer. Research results suggest the pH of the CBNG produced water outfalls increases substantially in corresponding disposal ponds due to degassing of CO (sub 2) (carbon dioxide) from the disposal ponds. Observed high SAR values in CBNG disposal ponds compared to outfalls were attributed to increase in Na (super +) and decrease in Ca (super 2+) concentrations. The decrease in Ca (super 2+) concentration is attributed to the precipitation of calcite. Trace element concentrations such as As (arsenic), Cr (chromium), and Cu (copper) appear to increase in disposal ponds. Barium (Ba) and Mn (manganese) concentrations in the disposal ponds decreased substantially by precipitating as carbonate minerals into the sediments. Results of this study suggest that very minimum or no leaching of trace elements could occur from disposal pond sediments. However, further research is required to understand the role of SAR and sediment mineralogy in leaching of trace elements from CBNG disposal pond in the PRB, WY.

The data were originally published as part of an industry report. The analysis was adapted to consider the compositional nature of the data and avoid potentially spurious correlations present in raw concentration data through the application of log-ratio transformations. Techniques such as robust variation arrays, robust principal component analysis, and relative variation plots were applied to log-ratio transformed data. Results from this battery of multivariate tools indicate that two primary processes affect the chemical evolution of the water returned to the surface during the first 90 days of production: mixing of injected water with formation brines of evaporated paleoseawater origin and injection of sulfate-rich water during hydraulic fracturing may stimulate sulfate reduction at some sites. Spatial variability in sulfate/alkalinity ratios appears to influence variations in geochemical controls on strontium versus barium with elevated proportions of strontium being found in more bicarbonate-poor environments, while barium is a larger proportion in sulfate-poor areas. Comparison of results using a log-ratio approach versus the more common analysis of concentration data reveals both similarities and some marked differences in the resulting interpretations. Results from this work are important in terms of both demonstrating methods to avoid mathematical inconsistencies from using raw brine geochemical data and to further investigate the geochemical controls on produced waters generated from shale gas reservoirs.

The dynamic model can describe both substrate and pH changes in the anode chamber of a double-chamber MFC. It was developed using finite differences and incorporates basic mass transfer concepts. Model simulation results could fit the experimental data for substrate consumption well, while there was a moderate discrepancy (maximum 0.11 pH unit) between the simulated pH and the experimental data. A parametric sensitivity analysis showed that increases in acetate and propionate consumption rates can cause great decrease in chemical oxygen demand (COD) in the anode chamber, while an increase in glucose consumption rate does not result in significant changes of COD reduction. Therefore, the rate limitation steps of glucose degradation are the oxidations of secondary degradation products of glucose (acetate and propionate). Due to the buffering effect of the nutrient solution, the increases in glucose, acetate and propionate consumption rates did not result in much change on pH of the anode chamber.

Upon injection of CO (sub 2) , the pore fluids in deep formations can be changed from oil/saline water to CO (sub 2) or CO (sub 2) dominated. The type of fluid is important not only because the fluid must fracture the rock, but also because rocks saturated with different pore fluids behave differently. We investigated the influence of fluid properties on fracture propagation behavior by using the cohesive zone model in conjunction with a poroelasticity model. Simulation results indicate that the pore pressure fields are very different for different pore fluids even when the initial field conditions and injection schemes (rate and time) are kept the same. Low viscosity fluids with properties of supercritical CO (sub 2) will create relatively thin and much shorter fractures in comparison with fluids exhibiting properties of water under similar injection schemes. Two significant times are recognized during fracture propagation: the time at which a crack ceases opening and the later time point at which a crack ceases propagating. These times are very different for different fluids. Both fluid compressibility and viscosity influence fracture propagation, with viscosity being the more important property. Viscosity can greatly affect hydraulic conductivity and the leak-off coefficient. This analysis assumes the in-situ pore fluid and injected fluid are the same and the pore space is 100% saturated by that fluid at the beginning of the simulation.

Success of sequestering CO sub(2) in underground reservoirs is strongly dependent on the prevention of leakage back into the atmosphere and the ability to mitigate should significant leakage occur. Both detection of leakage and reliable risk mitigation plans require a robust monitoring system. The space and time span of CO sub(2) sequestration projects is large, which results in trade-offs between cost and robustness of monitoring. In order to make a cost-effective decision without compromising monitoring effectiveness, knowledge of CO sub(2) transport in the vadose zone and seepage mechanisms into the atmosphere is essential. This study focuses on the simulations of hypothetical CO sub(2) leakage into the ~100 m thick vadose zone at an actual site in the San Juan Basin, the United States. Hypothetical leaks were assumed to occur through abandoned wellbores whose integrity had been compromised below the water table. Results show that, at the leak rates analyzed, CO sub(2) did not express itself at the wellhead for extended periods due to the extremely thick vadose zone. It was also seen that even after decades of simulated leakage, point measurements of CO sub(2) flux into the atmosphere may not reach levels distinguishable from the background. The regional seepage pattern, however, is both measurable and distinguishable. This finding can be used for designing cost-effective and robust near-surface monitoring networks and algorithms.

An ideal catalyst would be capable of using as much of the solar spectrum as possible, in particular the visible region. One interesting class of materials that have the potential to provide this photoactivity is known as delafossites. These materials have the general formula ABO sub(2) and are based on the mineral CuFeO sub(2), also known as delafossite. They are especially interesting due to the ability to alter the band structure of these materials using chemical substitution. In particular, substitution on the B-site in these materials can be used to tune the physical properties of delafossites for specific applications. In this work, NaInO sub(2) and NaIn sub(0.9)Fe sub(0.1)O sub(2) have been studied and Fe substitution was found to decrease the band gap energy from 3.9 eV to 2.8 eV. The catalytic activity, measured by methylene blue dye degradation, of these delafossite materials was analysed and the reduction in band gap energy was found to result in increased visible light photoactivity. Computationally, thousands of supercells were examined in order to determine the most energetically favourable substituted structures and generate density of states plots in order to determine that the experimentally observed results were due to Fe-states increasing the energy of the highest occupied molecular orbitals.

This study reports on a three-step laboratory process for forming noncementing methane hydrate in sandy sediments: (1) initial HBS formation under excess-gas conditions; (2) slow saline water (5 wt % CaCl (sub 2) ) injection under strictly controlled pressure-temperature (P-T) conditions; and (3) a temperature warming/cooling cycle. Changes in compressional wave velocity (V (sub p) ) of sediment, as well as P-T condition, were monitored throughout the tests. The evolution of V (sub p) , in good agreement with rock physics model calculations, suggested that the transition from cementing hydrate into noncementing hydrate occurs during saline injection as well as temperature warming/cooling cycle. The proposed process appeared to be an efficient and consistent substitute for the existing methods, to form noncementing hydrate habit in sandy sediments.

The effect of CO sub(2) gradients on the microbial community from a brine aquifer was examined at reservoir pressure (14 MPa) and temperature (40 degree C). The community was exposed to pCO sub(2) at 0, 0.1, 1.4 and 14 MPa for up to 56 days and was examined using 16S rRNA gene clone libraries and qPCR. Diversity indices (equitability) were also determined. In addition, the effect of lowered pH without CO sub(2) exposure was examined. Exposure to CO sub(2) resulted in a decrease in microbial diversity and a decrease in 16S rRNA gene concentrations. After 56 days, no 16S genes were recovered following exposure to 1.4 MPa pCO sub(2) or greater. Exposure to 0.1 MPa pCO sub(2) resulted in 16S gene concentrations an order of magnitude less than 0 MPa pCO sub(2). The equitability of 0 MPa exposure (0.54) decreased with 0.1 MPa exposure to 0.29. Microbial community with the lowered pH (pH = 4.4) and 0 MPa pCO sub(2) resulted in 5 orders of magnitude increased 16S gene concentration than reactors with CO sub(2) exposure, indicating that CO sub(2) was detrimental independent of pH. This suggests that even buffered reservoirs may have a decreased microbial population due to injected CO sub(2). Halotolerant strains Halomonasand Marinobacterappeared to be the most tolerant to CO sub(2) exposure and decreased pH. This is the first study to examine the initial microbial community response to a gradient of CO sub(2) that would follow geologic carbon sequestration.

The Eastern Gas Shales Project, funded by the U.S. Department of Energy in the 1980s, investigated the gas potential of organic-rich, Devonian black shales in the Appalachian, Michigan, and Illinois basins. One of these eastern shales is the Middle Devonian Marcellus Shale, which has been extensively developed for natural gas and natural gas liquids since 2007. The Marcellus is one of the basal units in a thick Devonian shale sedimentary sequence in the Appalachian basin. The Marcellus rests on the Onondaga Limestone throughout most of the basin, or on the time-equivalent Needmore Shale in the southeastern parts of the basin. Another basal unit, the Huntersville Chert, underlies the Marcellus in the southern part of the basin. The Devonian section is compressed to the south, and the Marcellus Shale, along with several overlying units, grades into the age-equivalent Millboro Shale in Virginia. The Marcellus-Millboro interval is far from a uniform slab of black rock. This field trip will examine a number of natural and engineered exposures in the vicinity of the West Virginia-Virginia state line, where participants will have the opportunity to view a variety of sedimentary facies within the shale itself, sedimentary structures, tectonic structures, fossils, overlying and underlying formations, volcaniclastic ash beds, and to view a basaltic intrusion.

The effects of friction and particle-size distribution (PSD) on some design-significant parameters, such as minimum fluidization and bubbling velocities, are also investigated. For these types of particles, cohesive forces are observed as necessary to fully exhibit the role friction plays in commonly observed phenomena, such as pressure overshoot and hysteresis around minimum fluidization. This study also shows that a full-experimental PSD consisting of a dozen particle sizes may be sufficiently represented by a few particle diameters. Reducing the number of particle types may benefit the continuum approach, which is based on the kinetic theory of granular flow, by reducing computational expense, while still maintaining the accuracy of the predictions.

The most commonly used primary components of growth substrates are expanded shales and clays, which are produced by heating in a high-temperature rotary kiln, requiring significant energy input. In this study, we examined the potential supplementation of conventional green roof growth substrates using available coal combustion by-products (CCBs) such as fly ash, and waste Marcellus gas well drill cuttings. These materials may represent satisfactory replacements for a fraction of the less energy efficient growth substrate materials. They also have the potential to introduce unacceptable levels of inorganic and organic contaminants to roof runoff, adversely modify soil and runoff pH, and limit plant growth. Over 50 fly and bottom ashes from coal combustion power plants were leached with natural rainwater - these produced a wide range in pH and metal concentrations and varied in their ability to retain water. Soluble components of CCBs were generally released in distinctive and explainable patterns based on the initial pH of the starting material and could be grouped by their relative abundance in solution. Soluble Ca, S, Na, K, Sr, and Ba were found in greatest abundance, with Ca and Na release being primarily associated with high pH CCB materials. A wide variety of trace elements, including Mn, Cr, Mo, Co, As, Li, Cu, Sn, U, Cd and Fe, were detected. Heavy metal release was usually associated with low pH CCB materials, whereas As and Cr were released from high pH materials. Lettuce seed germination was optimal in circumneutral pH soil mixtures produced from neutral pH CCBs or from appropriate mixtures of low and high pH CCBs. Marcellus shale drill cuttings were the only soil amendments to completely inhibit plant germination, possibly due to incorporated organic drilling mud components. Plant pot studies on a building green roof demonstrated the ability of sedum cuttings to become established in selected CCB-amended substrate mixtures adjusted to produce a circumneutral pH.

The charcoal from approximately one acre of woodland was needed to fuel the average iron furnace for one day, so the availability of forested land and the supply of charcoal were factors that frequently limited the life of a furnace. Many individual charcoal hearths, which were flat, cleared areas where cut wood was stacked and prepared for charcoal production, are known to be present on the mountain slopes around remaining furnace ruins, but relatively few have been specifically identified. The community of Greenwood Furnace in northeastern Huntingdon County, Pennsylvania, was a busy industrial complex based around charcoal iron production, and required the production of large amounts of charcoal from the surrounding forests. In our study, many charcoal hearths were readily viewed in shaded relief images of the LiDAR digital elevation model (DEM) as circular features resembling small craters. The LiDAR data was primarily acquired to produce an accurate and high-resolution bare earth model of Pennsylvania (3.2-foot pixel, 1-meter equivalent raster GeoTIFF DEM). Approximately 500 historic charcoal hearths were readily identified in a 10359 hectare (40 square mile) area surrounding Greenwood Furnace and were manually identified as shaded relief images. Strings of hearths were readily evident along similar topographic contour lines on the adjacent hillsides. Adjusting the sun angle for azimuth and altitude was very effective in confirming hearth sites. In this study, we employed various methods of spatial analysis such as pattern and cluster analysis, to evaluate the observed distribution of relic charcoal hearth sites. These results are related to the regional topography and the economics of charcoal transportation as they influenced the life of the iron furnace.

The benefits of green roofs can include: 1) The capture and evaporation of precipitation, reducing the volume and speed of storm water runoff leaving the site; 2) The lowering of the temperature of storm water runoff, which helps maintain the cool stream temperatures needed by fish; 3) The improvement of air quality by reducing smog; 4) The reduction of "heat island" effects by cooling of the ambient air; 5) Increasing the amount of vegetation and wildlife habitat; 6) Thermal insulation of existing roofs, with lower cooling and heating costs for buildings; and 7) Longer lifespans of existing roofs due to reduced exposure to the weather. Green roof growth substrates must be relatively light-weight, retain moisture, be composed of non-toxic materials that do not pollute the associated rainfall and runoff, and allow plant growth. The most commonly used substrates are produced by heating in a high-temperature rotary kiln, which requires significant energy input. We are examining the impacts of supplementing conventional green roof growth substrates with available waste products from coal-fired power plants and gas well operations, such as fly and bottom ashes and drill cuttings. These materials may represent satisfactory substitutes for a fraction of less energy efficient growth substrate materials. However, they also have the potential to introduce unacceptable levels of inorganic and organic contaminants to roof runoff, adversely modify soil and runoff pH, and limit plant growth. The screening of over 50 fly and bottom ashes from coal combustion power plants leached with natural rainwater showed a wide range in resulting pHs, metal concentrations, and ability to retain water. Drill cuttings from a Marcellus gas well in southwestern PA likewise indicated the potential mobility of several heavy metals and oxyanions, including As, Cd, Cr, Pb, Se and U. Preliminary results of plant toxicity and growth studies on mixtures of these materials and growth substrate are presented, and scenarios for the geochemical immobilization of potentially toxic compounds via the control of pH and other variables are discussed.

After water is discharged from a mine portal, dissolved CO (sub 2) degasses rapidly as a function of distance and topography and becomes more aerated in the process. The accurate monitoring of CO (sub 2) in such environments by conventional methods, such as alkalinity titration, is difficult due to the geochemical instability of the water during sample processing. Earlier work in our laboratories showed that a volume expansion method used in the beverage industry worked well in determining CO (sub 2) in mine waters under field conditions, but it still suffered from the need to collect grab samples and transfer them to a carbonation meter, a step that results in the loss of some CO (sub 2) . Additionally, the ability to collect CO (sub 2) data remotely to determine natural fluctuations over time is desirable. Here we report on the preliminary use of a non-dispersive infrared (NDIR) CO (sub 2) sensor enclosed in a gas-permeable membrane to make measurements directly in the discharge of an abandoned bituminous coal mine in southwestern PA. Results showed that this method was superior to both alkalinity titration and volume expansion as a method of CO (sub 2) detection in this environment. Long-term measurements in the fluctuation of dissolved CO (sub 2) were possible, especially in waters nearest the portal, where the active precipitation of iron did not interfere with gas transfer across the synthetic membrane covering the NDIR sensor. Additional examples of the benefits of this analytical approach will be presented.

This paper presents time-lapse inorganic water chemistry data sampled from three adjacent horizontal natural gas wells for ten days directly after hydraulic fracturing and again after forty-four days. These data are compared to historic well data from conventional Paleozoic oil and gas reservoirs in Pennsylvania. Similarities between the two data sets indicate that the flowback water sampled for this study is a mixture of in-situ brines and drilling fluids. Alkalinity (as CaCO (sub 3) ) generally decreases in wells 1 and 2 (range: 152-410 mg/L ). In well 3, alkalinity decreases from 403 mg/L to 267 mg/L and then spikes to 903 mg/L. The concentration of most inorganic constituents (Ba, Br, Ca, Cl, K, Li, Mn, Na, S, Sr) increases steadily in all wells. Exceptions to this trend are Fe, Mg, and SO (sub 4) . During the first ten days, Fe concentrations in wells 1 and 2, rise and fall twice. Concentrations range from 0.496 mg/L to 84.5 mg/L. After the second fall, Fe concentrations in the wells increase by day forty-four to 72.2 mg/L and 87.3 mg/L, respectively. Fe concentration in well 3 rises from 11.5 mg/L to 94.2 mg/L, with a rapid increase during day seven. Mg concentrations in all three wells rise and then fall (range: 165- 585 mg/L) within the first four days and then increase by day forty-four (range: 937-985 mg/L). SO (sub 4) concentrations increase rapidly and then decrease by day forty-four (range: 8.10-42.5 g/L). SO (sub 4) M/S (sub total) M ratios indicate that SO (sub 4) accounts for 4.70% to 54.8% of S (sub total) .x/Br ratios show similar trends to concentration, suggesting that the reaction between in-situ brines and drilling fluids may not represent a simple dilution as previously believed.

Previously, the double perovskite BaYMn sub(2)O sub(5+ delta ) was shown to rapidly and reversibly store and release oxygen with unprecedented kinetics. In this work, four double perovskite materials, BaLaFe sub(2)O sub(5+ delta ), BaLaCo sub(2)O sub(5+ delta ), BaYCo sub(2)O sub(5+ delta ), and BaYFe sub(2)O sub(5+ delta ), were synthesized and characterized. TGA experimental results for all four samples demonstrate rapid and reversible oxygen storage. The two Fe-containing compounds are the most stable for multiple adsorption/desorption cycles with both nitrogen/air and hydrogen/air at multiple temperatures and have been demonstrated to oxidize methane.

We studied carbon dioxide (CO2) interaction with source clay samples from The Clay Minerals Society. The manometric, infrared (IR) and X-ray diffraction (XRD) data indicated that montmorillonite can permanently trap CO2 molecules in its interlayer, after dynamic exposure to supercritical CO2. Such trapping is quite secure and appears to result in partial carbonate formation. Molecular dynamics simulations were carried out to investigate CO2 intercalation into the interlayer and its interaction with interlayer species. Previously reported results of simulations using simplified smectite models suggested that the experimentally observed red shift of the asymmetric-stretch vibrational mode for the trapped carbon dioxide can be attributed to induced polarization of the CO2 molecule by the interlayer water molecules. Modified smectite models were designed to account for the naturally occurring structural disorder that allows guest molecules to occupy localized interlamellar voids. In such models, energy dependences and structural rearrangements of the interlayer species are governed by rotational misalignment in turbostratically disordered clay. CO2 invasion in the interlayer disrupts the long-range ordering of water molecules and cations thus forcing the system to adopt energetically unfavorable configurations. New findings indicate that interaction between intercalated CO2 and H2O is limited and, with the increasing interlayer hydration, CO2 preferentially accumulates in interlamellar voids. The vibrational spectra produced by the new model, assuming that clay systems can exist in fractional hydration states, show either a combination of undisturbed and red-shifted asymmetric-stretch modes or a broad peak consistent with the multiple smeared peaks, which explain the multi-mode features that have appeared in experimental IR spectra.

Water that is co-produced during gas extraction is likely influenced by fluid/rock interactions during hydraulic fracturing (HF) and monitoring changes in Sr isotope ratios can provide insight into reactions occurring within the shale formation. However, questions persist as to what controls the Sr isotopic composition of Marcellus Shale fluids, especially during HF. Here we compare laboratory experiments, simulating the dissolution of the Marcellus Shale during HF, with a time-series of water samples taken from a Marcellus Shale gas wells after HF has occurred. For the laboratory experiments, a core sample of Marcellus Shale from Greene County, PA was crushed and placed into a high P and T reaction vessel. Solutions were added in two different experiments: one with synthetic brine, and another using brine+HF fluid. The HF fluid was made up of components listed on fracfocus.org. Experiments were run for approximately 16 days at 27.5 MPa and 130 degrees C. Aqueous samples were periodically removed for analysis and Sr isotope ratios were measured by MC-ICP-MS. Using just brine, the pH of the solution decreased from 7.6 to 5.3 after 24 hrs, then reached a steady state at approximately 6.1. Sr/Ca molar ratios in the fluid started at 2.3 after 24 hours and decreased to 1.8 over approximately 16 days. During this time only 6% of the total inorganic carbon (TIC) dissolved from the shale. The epsilon Sr values started at +43.2 and decreased to +42.4. In the experiment using brine+HF fluid, the pH started at 1.8 and rose slowly to a steady value of 5.6 by day 6. The Sr and Ca concentrations were higher than the brine experiment, but the Sr/Ca ratios remained lower at approximately 0.3 through the experiment. The increased Ca release, as well as the dissolution of over 60% of the TIC, suggests the dissolution of a carbonate mineral component due to the HF fluid. The epsilon Sr started at +36.5 at 24 hours and decreased to +35.5 at the end. At the field scale, the Sr/Ca molar ratios in produced water samples collected from four hydraulically fractured Marcellus Shale gas well over a 2 to 3 year period had median values of 0.07 to 0.08. The epsilon Sr values were also lower than the laboratory experiments with median values ranging from +26.6 to +31.3. Differences in the Sr isotopic results between the laboratory experiments, in combination with the TIC data, suggest the presence of at least two distinct Sr reservoirs in the sample: 1) water-soluble or exchangeable Sr, and 2) Sr incorporated into carbonate minerals. The lower epsilon Sr values using brine+HF fluid may be explained by the increased dissolution of carbonates. These results suggest that carbonate minerals within the Marcellus Shale may help control Sr isotopic composition of produced waters from these formations. However, deviations in Sr isotope values measured at the field sites may suggest an additional Sr source, such as interaction with other fluids within the formation.

The approach that is being used is to divide the storage and containment system into components (e.g., reservoirs, seals, wells, groundwater aquifers), to develop detailed models for each component, to generate reduced order models (ROMs) based on the detailed models, and to reconnect the reduced order models within an integrated assessment model (IAM). CO2-PENS, developed at Los Alamos National Lab, is being used as the IAM for the simulations in this study. The benefit of this approach is that simulations of the complete system can be generated on a relatively rapid time scale so that Monte Carlo simulation can be performed. In this study, hundreds of thousands of runs of the IAMs have been generated to estimate likelihoods of the quantity of CO2 released to the atmosphere, size of aquifer impacted by pH, size of aquifer impacted by TDS, and size of aquifer with different metals concentrations. Correlations of the output variables with different reservoir, seal, wellbore, and aquifer parameters have been generated. Importance measures have been identified, and inputs have been ranked in the order of their impact on the output quantities. Presentation will describe the approach used, representative results, and implications for how the Monte Carlo analysis is implemented on uncertainty quantification.

The NETL-Regional University Alliance (NETL-RUA) has a broad research portfolio connected with development of hydraulically-fractured shale resources in the Appalachian Basin. Through a combined field, experimental, modeling, and existing data evaluation effort, the following questions are being addressed: 1) Which subsurface features control the extent to which fractures migrate out of the target fracture zone? 2) Can we improve methods for analyzing natural geochemical tracers? What combination of natural and synthetic tracers can best be used to evaluate subsurface fluid and gas migration? 3) How is wellbore integrity affected by existing shallow gas? Can we predict how shallow groundwater hydrology changes due to drilling? 4) Where are existing wellbores and natural fractures located? What field methods can be used to identify the location of existing wells? To date the NETL-RUA team has focused on four key areas: fracture growth, natural isotopic tracers, impacts of well drilling on shallow hydrology, and statistics on wellbores (locations and conditions). We have found that fracture growth is sensitive to overburden geomechanical features, and that the maximum fracture height outside of the Marcellus Shale aligns with prior assessments (e.g., Fisher et al., 2012). The team has also developed methodologies for the rapid preparation of produced-water samples by MC-ICP-MS and ICP-MS; we are using these methodologies to investigate the potential of key geochemical indicators and species of interest (Sr, Ra) as indicators of fluid and gas migration in the Appalachian Basin. Experimental work on subsurface geochemical reactions in the presence of hydraulic fracturing fluid is underway to evaluate potential impacts on produced water chemistry and fracture stability within the shale formation. Additional laboratory experiments, coupled with modeling efforts, are evaluating the effects of well drilling on shallow groundwater hydrology, and the potential for shallow gas to affect cement hydration. At the field scale, the density and distribution of existing wellbores are being assessed through detection with remote magnetometer surveys, and compilation and analysis of existing wellbore databases. Results from these varied research efforts will be used in future predictive assessments of the behavior of engineered shale gas systems.

Application of these elements as naturally occurring tracers during shale gas development is reliant on accurate quantitation of trace metals in hypersaline brines. We have modified and validated a liquid-liquid technique for extraction and pre-concentration of REE from saline produced waters from shale gas extraction wells with quantitative analysis by ICP-MS. This method was used to analyze time-series samples of Marcellus shale flowback and produced waters. Additionally, the total REE content of core samples of various strata throughout the Appalachian Basin were determined using HF/HNO3 digestion and ICP-MS analysis. A primary goal of the study is to elucidate systematic geochemical variations as a function of location or shale characteristics.

Evidence indicates that shale environments are marked by extreme conditions such as high temperature and pressure, low porosity, permeability and connectivity, and the presence of heavy metals and radionuclides. It has been postulated that many of these shales are naturally sterile due to the high pressure and temperature conditions under which they were formed. However, it has been shown in the Antrim and New Albany shales that microbial communities do exist in these environments. Here we review geochemical and microbiological evidence for the possible habitation of the Marcellus shale by microorganisms and compare these conditions to other shales in the U.S. Furthermore, we describe the development of sampling and analysis techniques used to evaluate microbial communities present in the Marcellus Shale and associated hydraulic fracturing fluid. Sampling techniques thus far have consisted of collecting flowback fluids from wells and water impoundments and collecting core material from previous drilling expeditions. Furthermore, DNA extraction was performed on Marcellus shale sub-core with a MoBio PowerSoil kit to determine its efficiency. Assessment of the Marcellus Shale indicates that it has low porosity and permeability that are not conducive to dense microbial populations; however, moderate temperatures and a natural fracture network may support a microbial community especially in zones where the Marcellus intersects more porous geologic formations. Also, hydraulic fracturing extends this fracture network providing more environments where microbial communities can exist. Previous research which collected flowback fluids has revealed a diverse microbial community that may be derived from hydrofrac fluid production or from the subsurface. DNA extraction from 10 g samples of Marcellus shale sub-core were unsuccessful even when samples were spiked with 8 X 108 cells/g of shale. This indicated that constituents of shale such as high levels of carbonates, humic acids and metals likely inhibited components of the PowerSoil kit. Future research is focused on refining sample collection and analyses to gain a full understanding of the microbiology of the Marcellus Shale and associated flowback fluids. This includes the development of an in situ osmosampler, which will collect temporally relevant fluid and colonized substrate samples. The design of the osmosampler for hydraulic fracturing wells is being adapted from those used to sample marine environments. Furthermore, incubation experiments are underway to study interactions between microbial communities associated with hydraulic fracturing fluid and Marcellus Shale samples. In conclusion, evidence suggests that the Marcellus shale is a possible component of the subsurface biosphere. Future studies will be valuable in determining the microbial community structure and function in relation to the geochemistry of the Marcellus Shale and its future development as a natural gas resource.

The depositional environment governs its solid-phase association in the sediment, which in turn will influence degree of remobilization during hydraulic fracturing. Organic carbon (OC), trace element (TE) and REE distributions have been used as tracers for assessing deep water redox conditions at the time of deposition in the Midcontinent Sea of North America (Algeo and Heckel, 2008), during large-scale oceanic anoxic events (e.g., Bunte, 2009) and in modern OC-rich sediments underlying coastal upwelling areas (e.g., Brumsack, 2006). We will present REE and As data from a collection of six different locations in the continental US (Kansas, Iowa, Oklahoma, Kentucky, North Dakota and Pennsylvania), ranging in age from Devonian to Upper Pennsylvanian, and from a Cretaceous black shale drilled on the Demerara Rise during ODP Leg 207. We interpret our data in light of the depositional framework previously developed for these locations based on OC and TE patterns, to document the mechanisms leading to REE and As accumulation, and explore their potential use as environmental proxies and their diagenetic remobilization during burial, as part of our future goal to develop a predictive evaluation of arsenic release from shales and transport with flowback waters. Total REE abundance (Sigma REE) ranged from 35 to 420 ppm in an organic rich sample from Stark shale, KS. PAAS-normalized REE concentrations ranged from 0.5 to 7, with the highest enrichments observed in the MREE (Sm to Ho). Neither the Sigma REE nor the MREE enrichments correlated with OC concentrations or postulated depositional redox conditions, suggesting a principal association with aluminosilicates and selective REE fractionation during diagenesis. In the anoxic reducing environments in which black shales were deposited, sulfide minerals such as FeS2 trap aqueous arsenic in the crystal lattice, but As is also known to bind to the charged surfaces of clay minerals. Our arsenic concentration data show that the highest abundances (up to 70 ppm) are found in sediments with the highest total sulfur concentration (to 2.6 ppm), but there was no clear correlation with organic carbon or aluminosilicate content. We compare our results with preliminary data from a series of flowback waters sampled from ten producing wells in Pennsylvania and from high-pressure high-temperature experimental leaching of Marcellus Shale samples.

It is used for modeling flows, pressures and compositions in such natural gas reservoirs, storage reservoirs, and carbon dioxide reservoir storage. It was first developed in 1997 and is subject to continuous improvements. Originally, communication between rock matrix and fracture network was by flows from and to immediately adjacent fractures and matrix. We report on the capability of flows occurring across a rock matrix.

Therefore, CO2 injected into deep ocean sediments may be buoyancy-trapped and may not require an impermeable caprock to prevent upward migration. Overlying sediments provide a diffusion-limited transport barrier, but more critically must provide the geomechanical stability to allow for CO2 injection. While there are some permeable sandy sediments at the necessary seafloor depths, the dominant pelagic lithologies are impermeable clays and low-permeability calcareous oozes. Pelagic calcareous ooze diagenesis generally results solely from the compressional weight of overlying sediments. Nearly-monotonically decreasing porosity and hence decreasing permeability lead to increasing stresses and material strengths with depth below the seafloor. Permeabilities in pelagic calcareous sediments are in the 1-100 microDarcy range, comparable to permeabilities found in tight oil and shale gas fields where fracturing is required to increase production. Previously (1) we used LANL's Finite Element Heat and Mass Transfer Code (FEHM) to show that in this system shear failure will precede hydraulic fracturing and that the shear failure breakdown zone propagates to the seafloor ahead of the CO2 front. FEHM models the flow of both CO2 and water while solving for the geomechanical stress state. Shear failure due to injection overpressure is simulated as an increase in permeability along failed nodes. Here we present updated results for CO2 injection from a vertical well into an idealized 3-D model with and without shear failure. The effect of variations in injection interval depth, seafloor depth, injection rate, fracturing pressure, permeability, porosity, and rock strength are presented. Finally, we present a comparison of several different reservoir engineering scenarios with the aim of maximizing total injected CO2 while avoiding CO2 reaching the seafloor.

This study evaluates the redox effects that co-contaminants such as H (sub 2) S present to the CO (sub 2) -cement reaction system via synchrotron X-ray XANES mapping specific to the iron and sulfur edge energies. Portland Class H cement was exposed to various proportions of H (sub 2) S:CO (sub 2) in 1% NaCl saturated brine (1%, 21 mol%, and 40% H (sub 2) S) under supercritical conditions (50 degrees C and 15 MPa). The reaction of cement with H (sub 2) S-CO (sub 2) results in the formation of pyrite associated with the Fe-rich cement clinker phase, brownmillerite (also termed ferrite). Ferrite has not reacted in previous exposures to CO (sub 2) alone, which was confirmed by synchrotron spectroscopic analysis of cement exposed to supercritical CO (sub 2) alone. Thus it is hypothesized that the reaction is a result of redox conditions introduced by H (sub 2) S. The synchrotron X-ray microprobe fluorescence (mu XRF) imaging and spectroscopy capabilities at beamlines 2-3 and 14-3 at SSRL were used to collect multiple energy (ME) maps for both Fe and S in order to evaluate reaction fronts in the cement matrix and to monitor the chemical changes in the cement associated with exposure to CO (sub 2) (and H (sub 2) S) at sequestration conditions. The use of this micro-spectroscopy technique allows for in-situ identification of any reaction intermediates (including amorphous materials) for the Fe and S phases in the cement. The coupled mu XANES and mu XRF data were used to generate iron and S speciation maps of the cement cores. Synchrotron microprobe capabilities at 2-3 were used to collected ME maps of Fe, and show differences in Fe oxidation between the rims (Fe (super 2+) ) and cores (Fe (super 3+) ) of the cement thin section. Analysis of Fe XANES indicates that there are potentially 4+ distinct coordination environments for the Fe in the cement cores studied: pyrite, ferrihydrite, brownmillerite (Fe (super 3+) , and/or Fe (super 2+) ) and potentially amorphous Fe-S. In a similar manner, S was evaluated by collecting multiple energy maps through the S-edge using beamline 14-3 at SSRL. The S ME maps revealed much broader reaction fronts as revealed by the iron mapping alone. Analysis of S XANES spectra is ongoing, but preliminary results indicate that possibly 6 different binding environments are likely in the cements depending on the H (sub 2) S concentration: FeS, FeS (sub 2) , S, a sulfite phase, and potentially two different sulfates (gypsum and ettringite). The results indicate that S oxidation state likely grades from S (super +6) in the core of the cement to S (super -1) in the rim of the cement, with S oxidation states ranging from S (super 4+) to S (super 0) in zones in between. This work will serve to better understand the geochemical reactions in the cement upon addition of S co-constituents in order to better assess potential impacts on long-term cement integrity.

During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compounds, and result in biocorrosion that complicates water and waste management and increases production costs. Here, we describe the microbial ecology at multiple depths of three flowback impoundments from the Marcellus shale that were managed differently. 16S rRNA gene clone libraries revealed that bacterial communities in the untreated and biocide-amended impoundments were depth dependent, diverse, and most similar to species within the taxa gamma -proteobacteria, alpha -proteobacteria, delta -proteobacteria,Clostridia,Sy nergistetes,Thermotogae,Spirochetes, and Bacteroidetes. The bacterial community in the pretreated and aerated impoundment was uniform with depth, less diverse, and most similar to known iodide-oxidizing bacteria in the alpha -proteobacteria. Archaea were identified only in the untreated and biocide-amended impoundments and were affiliated to the Methanomicrobia class. This is the first study of microbial communities in flowback water impoundments from hydraulic fracturing. The findings expand our knowledge of microbial diversity of an emergent and unexplored environment and may guide the management of flowback impoundments.

20467561 AB - Invert emulsions are used to drill for oil and gas when good wellbore stability and high temperature tolerance are required. These drilling fluids contain a solid phase and two immiscible liquid phases stabilised with a polymeric surfactant. In ultra deep drilling, due to high temperature, the surfactant degrades causing phase separation. However, fine particles can be used as stabilisers, and the result is a Pickering emulsion. Here, we demonstrate that the use of a combination of hydrophobic nanoparticles and organically modified nanoclay results in stable water-in-oil invert emulsions model drilling fluids. These gel-like model fluids have the desired plastic viscosity and yield stress suitable for drilling fluid applications that can be modified by adjusting the nanoparticle-content. Aging experiments at 225 degree C showed that they also have high-temperature stability for demanding drilling operations.

In this work, we investigated the sorption and swelling behavior of several Eastern and Western US coal samples from the Central Appalachian Basin and from the San Juan Basin. The CO (sub 2) sorption isotherms have been completed at 55 degrees C for wet and dry samples. The role of mineral components in coal, coal swelling, effects of temperature and moisture, and the error propagation have been analyzed. Changes in void volume due to dewatering and other factors such as caging of carbon dioxide molecules in coal matrix were identified among the main factors affecting accuracy of the carbon dioxide sorption isotherms. The (helium) void volume in the sample cells was measured before and after the sorption isotherm experiments and was used to build the volume-corrected data plots.

In general, dry. regenerate flue gas cleanup techniques that use a sorbent can have various advantages, such as simultaneous removal of pollutants, production of a salable by-product, and low costs when compared to commercially available wet scrubbing technology. Due to the temperature of reaction, the placement of the process into an advanced power system could actually increase the thermal efficiency of the plant The Moving-Bed Copper Oxide Process is capable of simultaneously removing sulfur oxides and nitric oxides within the reactor system. In this regenerable sorbent technique, the use of the copper oxide sorbent was originally in a fluidized bed, but the more recent effort developed the use of the sorbent in a moving-bed reactor design. A pilot facility or life-cycle test system was constructed so that an integrated testing of the sorbent over absorption/regeneration cycles could be conducted. A parametric study of the total process was then performed where all process steps, including absorption and regeneration, were continuously operated and experimentally evaluated. The parametric effects, including absorption temperature, sorbent and gas residence times, inlet SO sub(2) and NO sub(X) concentration, and flyash loadings, on removal efficiencies and overall operational performance were determined. Although some of the research results have not been previously published because of previous collaborative restrictions, a summary of these past findings is presented in this communication. Additionally, the potential use of the process for criteria pollutant removal in oxy-firing of fossil fuel for carbon sequestration purposes is discussed.

While co-feeding has the potential to reduce the net carbon footprint of commercial gasification operations, success of this strategy requires investigation of the effects of coal/biomass co-feeding on reaction kinetics and product distributions. Southern yellow pine was pyrolyzed in a semi-batch type drop tube reactor with either Powder River Basin sub-bituminous coal or Mississippi lignite at several temperatures and feed ratios. Product gas composition of expected primary constituents (CO, CO(2), CH(4), H(2), H(2)O, and C(2)H(4)) was determined by in situ mass spectrometry while minor gaseous constituents were determined using a GC-MS. Product distributions are fit to linear functions of temperature, and quadratic functions of biomass fraction, for use in computational co-pyrolysis simulations. The results are shown to yield significant nonlinearities, particularly at higher temperatures and for lower ranked coals. The co-pyrolysis product distributions evolve more tar, and less char, CH(4), and C(2)H(4), than an additive pyrolysis process would suggest. For lignite co-pyrolysis, CO and H(2) production are also reduced. The data suggests that rapid pyrolysis of biomass produces hydrogen that stabilizes large radical structures generated during the early stages of coal pyrolysis. Stabilization causes these structures to be released as tar, rather than crosslinking with one another to produce secondary char and light gases. Finally, it is shown that, for the two coal types tested, co-pyrolysis synergies are more significant as coal rank decreases, likely because the initial structure in these coals contains larger pores and smaller clusters of aromatic structures which are more readily retained as tar in rapid co-pyrolysis.

Solid-liquid transitions are observed for cyclooctane, cis-1,2-dimethylcyclohexane, trans-1,4-dimethylcyclohexane, p-xylene. o-xylene, and 2-methylnaphthalene. However, methylcyclohexane, ethylcyclohexane, cis-1,4-dimethylcyclohexane, and m-xylene remained liquid over the same operating pressure and temperature ranges. The experimental solid-liquid transition data are well represented with two empirical equations, the Simon equation and a 2nd-order polynomial equation. Data obtained in this study agree with literature data within (plus-or-minus sign)0.4% for 2-methylnaphthalene and (plus-or-minus sign)0.2% for p-xylene.

This paper presents an analytical solution for the steady Darcy flow of an incompressible fluid through a homogeneous, isotropic porous medium filling a channel bounded by symmetric wavy walls. This packed channel may represent an idealized packed fracture, a situation which is of interest as a potential pathway for the leakage of carbon dioxide from a geological sequestration site. The channel walls change from parallel planes, to small amplitude sine waves, to large amplitude nonsinusoidal waves as certain parameters are increased. The direction of gravity is arbitrary. A plot of piezometric head against distance in the direction of mean flow changes from a straight line for parallel planes to a series of steeply sloping sections in the reaches of small aperture alternating with nearly constant sections in the large aperture bulges. Expressions are given for the stream function, specific discharge, piezometric head, and pressure.

AN - 1370123919; 23734594 AB - The unique physical and chemical properties of single-walled carbon nanotubes (SWNTs) make them ideal building blocks for the construction of hybrid nanostructures. In addition to increasing the material complexity and functionality, SWNTs can probe the interfacial processes in the hybrid system. In this work, SWNT-TiO2 core/shell hybrid nanostructures were found to exhibit unique electrical behavior in response to UV illumination and acetone vapors. By experimental and theoretical studies of UV and acetone sensitivities of different SWNT-TiO2 hybrid systems, we established a fundamental understanding on the interfacial charge transfer between photoexcited TiO2 and SWNTs as well as the mechanism of acetone sensing. We further demonstrated a practical application of photoinduced acetone sensitivity by fabricating a microsized room temperature acetone sensor that showed fast, linear, and reversible detection of acetone vapors with concentrations in few parts per million range.

The U.S. electricity generation sector faces uncertainties that include future demand, the costs of supply, and the effects of regulation policies. National policies that aim to promote "clean" energy sources may have different impacts for different areas of the country, so it is important to understand the regional effects in addition to the larger national picture. The primary purpose of this paper is to shed some light on the uncertainties associated with the outcomes of possible regulations. The study does not intend to make predictions of the probability or direction of environmental policy in the U.S. Rather, we examine a number of different scenarios and explore their possible impacts on the future of energy system. We focus on future projections for electricity generation mix, electricity costs, emissions and emissions abatement costs under different scenarios. We have examined the key regulations through analyzing various assumptions using the MARKet AUocation (MARKAL) model and the Environmental Protection Agency's Nine Region MARKAL Database (EPAUS9r). We have analyzed how command-and-control regulations and market-based environmental policy approaches could change the mix of fuels used for electricity generation, the amount of CO sub(2) emissions, and the cost of electricity in different parts of the U.S. In particular, we explore how some proposed features of different policies designs affect those outcomes and identify underlying causes of uncertainty about such outcomes. The analyzed policies lead to 6-25% reduction in total CO sub(2) emissions by 2035. The policies also result in modest increases on electricity costs nationally, but this masks a wide variety of effects across regions. The relationship between the policy's effects on costs depends on the design of the policy, regional resource endowments, and the existing generation mix of the region. Generally, the regions with existing high electricity marginal costs would tend to see only minor costs increases and the regions with low electricity marginal costs would see substantial costs increases. Modeling results illustrate that different regions have different preferences in environmental regulations policies and design.

Dry, 1 in. unconfined cores of Pittsburgh and Sewickly bituminous coals were exposed to supercritical CO(2) at 15.3 MPa (2200 psig) and 328 K (55 degree C) for 104 days. Prior to CO(2) exposure, coal structure and porosity - specifically macropores (>50 nm) - were imaged using FE-SEM. After CO(2) exposure, the imaged features were relocated, reimaged, and analyzed for structural changes. Brunauer-Emmett-Teller (BET) surface areas were evaluated from the adsorption isotherms of N(2) at 77 K and P/P(0) = 0.1-0.3. Micropore surface areas were determined from the low-pressure adsorption isotherms of CO(2) at 293 K using the Dubinin-Polanyi equation. FE-SEM analysis indicated that there were no significant changes observed in the pore areas in all coal samples after CO(2) exposure. Meso- and micropore characteristics were slightly affected by supercritical CO(2) exposure.

This study extends the curvature algorithm to a new curvature gradient algorithm and integrates both algorithms for fracture detection using a 3D seismic test data set over Teapot Dome (Wyoming). In fractured reservoirs at Teapot Dome formed by tectonic folding and faulting, curvature helps define the crestal portion of reservoirs that is associated with strong seismic amplitude and high oil productivity. In contrast, curvature gradient helps define the regional northwest-trending and the cross-regional northeast-trending lineaments that are associated with weak seismic amplitude and low oil productivity. In concert with previous reports from image logs, cores, and outcrops, an integrated seismic curvature and curvature gradient analysis suggests that curvature might help define areas of enhanced potential to form tensile fractures, whereas curvature gradient might help define zones of enhanced potential to develop shear fractures. In fractured reservoirs at Teapot Dome where faulting and fault-related folding contribute dominantly to the formation and evolution of fractures, curvature and curvature gradient attributes can be potentially applied to differentiate fracture mode, to predict fracture intensity and orientation, to evaluate fracture volume and connectivity, and to model fracture networks.

AN - 1321338515; 23427809 AB - A simple and scalable synthetic strategy was developed for the fabrication of one-dimensional SiC nanostructures-nanorods and nanowires. Thin sheets of single-walled carbon nanotubes (SWNTs) were prepared by vacuum filtration and were washed repeatedly with sodium silicate (Na2SiO3) solution. The resulting "glassy buckypaper" was heated at 1300-1500 °C under Ar/H2 to allow a solid state reaction between C and Si precursors to form a variety of SiC nanostructures. The morphology and crystal structures of SiC nanorods and nanowires were characterized using scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), energy-dispersive X-ray spectroscopy (EDX), electron diffraction (ED), and X-ray diffraction (XRD) techniques. Furthermore, electrical conductance measurements were performed on SiC nanorods, demonstrating their potential applications in high-temperature sensors and control systems.

However, effects from past and ongoing coal, oil, and gas production present a challenge in defining geochemical baselines that are necessary for accurate assessment of surface water impacts from unconventional shale gas development. In this study, focused on the Allegheny River basin of western Pennsylvania within the Marcellus exploration region, we use strontium (Sr) isotopes combined with elemental analysis to assess its ability to distinguish between sources such as Marcellus-derived produced waters, abandoned coal mine drainage (AMD), fluids from conventional Upper Devonian gas production, and fly ash impoundments. Preliminary results from stream water collected from approximately 45 sites along the Allegheny River and seven of its tributaries show that Sr varies across the watershed, with lower concentrations (mean [Sr] = 82 mu g/L) in the upper reaches and tributaries, and increasing concentrations downstream, reaching approximately 200 mu g/L where the Allegheny River enters the Ohio River near Pittsburgh. Anomalous Sr concentrations (as high as 2,500 mu g/L) are observed in two tributaries with high densities of centralized wastewater treatment (CWT) facilities. Preliminary Sr isotope data for two seasons indicate that most of the Allegheny River and its tributaries cluster around a narrow range of (super 87) Sr/ (super 86) Sr values, from 0.7125 to 0.7130 (= +47.3 to +53.8, where is the deviation of the (super 87) Sr/ (super 86) Sr from that of seawater in parts per ten thousand). However, values as high as +62 and as low as +35 are observed in tributaries with high Sr concentrations. While Sr concentrations are expected to vary across the watershed due to differences in silicate and carbonate weathering sources (as indicated by Mg/Na and Ca/Na ratios), in some cases anomalous Sr concentrations and isotopic compositions are consistent with mixing with fluids derived from natural gas production. The results also suggest that Sr isotope analysis combined with geochemical data can distinguish influx of produced water from Marcellus shale vs. Upper Devonian sources into streams.

The I2B coal seam in the Charqueadas coal field has been considered a target for enhanced coal bed methane production and CO (sub 2) sequestration. A detailed experimental study of the samples from this seam was conducted at the NETL with assistance from the Pontificia Universidade Catolica Do Rio Grande Do Sul. Such properties as sorption capacity, internal structure of the samples, porosity and permeability were of primary interest in this characterization study. The samples used were low rank coals (high volatile bituminous and sub-bituminous) obtained from the I2B seam. It was observed that the temperature effect on adsorption capacity correlates negatively with as-received water and mineral content. Langmuir CO (sub 2) adsorption capacity of the coal samples ranged 0.61-2.09 mmol/g. The upper I2B seam appears to be overall more heterogeneous and less permeable than the lower I2B seam. The lower seam coal appears to have a large amount of micro-fractures that do not close even at 11 MPa of confining pressure. Abstract Copyright (2013) Elsevier, B.V.

We will present pre- and post-hydraulic fracturing strontium (Sr) isotope data from a well-characterized Marcellus Shale horizontal drilling site in Greene County, Pennsylvania, in which vertical gas wells tapping the overlying Upper Devonian sands are in close proximity. The Upper Devonian gas-producing formations are >3,000 ft. above the Marcellus Formation and approximately 2,000 ft. below fresh water aquifers. This provides an opportunity to test the assumption that hydraulic fracturing is confined to the target formation, and that injected and formation waters do not migrate to overlying units. In order for Sr isotopes to be an effective tracer for fluid migration and mixing, there must be a large enough difference between the (super 87) Sr/ (super 86) Sr ratio of the end-member fluids. Samples collected at gas-water separators and/or stock tanks from four wells tapping Upper Devonian sands at this site yield (super 87) Sr/ (super 86) Sr values from 0.7199 to 0.7209 (typical analytical uncertainty + or -0.00002). This is significantly different from produced waters from horizontal wells in the Marcellus Formation from the same site, which range from 0.7113 to 0.7116, well within the range of values previously determined for Marcellus produced waters across Pennsylvania (0.7101-0.7121; Chapman et al., 2012, Env. Sci. Technol. 46, 3545-3553). Because Marcellus Formation produced waters can have Sr concentrations that are an order of magnitude greater than those of the Upper Devonian waters in this region, (super 87) Sr/ (super 86) Sr ratios of the latter are sensitive to small (>1-2%) intrusions of the former.

A comparison of background ambient concentrations of pollutants associated with natural gas operations with concentrations of the pollutants measured during the various phases of hydrofracturing operations enabled an evaluation of the impact the activities had on local air quality. Instruments in the laboratory measured the ambient concentrations of methane, carbon dioxide, carbon isotopes in methane and carbon dioxide, volatile organic compounds, nitrogen oxides, ozone, particulate matter, sulfur dioxide, ammonia, organic and elemental carbon aerosols, as well as several meteorological parameters. Monitoring commenced on March 8, 2012 and ended on June 19, 2012. During this time, there were periods of no well pad activity that could be compared to periods of hydraulic fracturing activities. Three of six horizontal wells were hydraulically fractured from April 24 to May 7, and the other three wells where hydraulically fractured from June 4-11. During periods of low or no activity on the well pad, measured pollutants registered typical atmospheric background values with few exceptions. However, significant increases in concentrations of methane, NOx, PM10, and several VOCs were observed during the two hydraulic fracturing operations. Methane concentration and isotope data were used to distinguish between biogenic and thermogenic methane. This technique provides a fingerprint of fugitive methane emissions from the wells. During the fracturing of the first three wells, peaks in methane concentration correlated with changes in the methane isotopic signature to reflect influence of thermogenic methane. A similar pattern was observed during the fracturing of the second three wells, although the most significant evidence of thermogenic methane occurred afterward during flowback. Preliminary results from this project suggest that although measurements did not at any time exceed applicable exposure limits or air quality standards, there were discernible differences in measurements collected during the various phases of operation at the well pad. A complete evaluation of all the collected data will be presented, with estimates of well pad emissions distinguished from background conditions.

In the early years of shale gas development, water for hydraulic fracturing was largely obtained from municipal taps, resulting in public concerns about impacts on local drinking water supplies, especially in semi-arid locations like Texas. Drillers have since discovered that much cheaper water of far lower quality will work for hydraulic fracturing in most shales, and a combination of recovered flowback fluid and lower-quality water such as wastewater treatment effluent are now generally used. Transporting large volumes of water to well sites has also changed, where the current practice is to use a centralized impoundment to collect raw water and then send it to nearby well sites via a temporary, overland pipeline. This greatly reduces the number of tanker trucks driving on fragile dirt roads in sensitive stream headwater areas. Such improvements are largely the result of economics as well as regulations. However, some new problems have arisen. For example, disposal of high TDS flowback from the Marcellus Shale was initially done using a conventional wastewater treatment plant, which allowed the dissolved salts to pass through into freshwater streams, often resulting in fish kills. Regulatory changes and higher disposal costs have reduced this impact by encouraging drillers to recycle and dispose of their flowback water via Underground Injection Control (UIC) wells. This has resulted in a new problem of induced seismicity caused by large volumes of injected wastewater. Several new issues have come to light from recent research. These include the potential for the drilling process itself to create groundwater surges in shallow aquifers, entraining pre-existing methane gas, minerals, and sediment. This can affect the taste and appearance of groundwater in nearby water wells, and may increase methane concentrations to explosive levels. Another concern is that toxic metals and radionuclides associated with black shale may oxidize at the surface and leach from any drill cuttings left behind. These issues will need to be addressed by industry practice, regulations, or both, but as evidenced by previous challenges, they can also be viewed as opportunities to improve economics and public opinion.

The water column modeling system is comprised of multiple models for the plume phase, the advection and diffusion dominated transport phase, an intermediary model between the two, and other models for handling the physical properties of oil/gas and the weathering of crude oil. The plume model simulates the buoyant jets and plumes emerging from a deepwater blowout source using Lagrangian control-volume analysis to track the movement and shape of the plume as it travels through the water column. The control-volumes are driven by buoyancy and the entrainment of ambient seawater, taking into account the ambient conditions, droplet sizes, gas bubbles, and gas hydrates. A newly developed jet coefficient and a 3-phase approach to droplet terminal velocities allow the model to balance between jet-like and plume-like behavior. The plume model performed capably when validated against the North Sea field experiments, and the use of the jet coefficient has provided improved simulations. Once reaching a terminal level, the intermediary model converts the control-volumes into Lagrangian parcel elements based on a probability density surface created from a moving oil concentration centroid, allowing for skewed and non-normal distribution of crude concentrations and droplet sizes. From there, the transport and weathering model takes over to simulate the final fate and distribution of oil, accounting for non-surfacing plumes and control volume sources. The development of this modeling system from the ground up has allowed for the adaptation of the entire system towards ultra-deepwater blowouts instead of simply assigning a deepwater plume model to a traditional oil spill process model.

Natural gas and produced water samples were collected from two vertical Marcellus Shale wells and seven Upper Devonian wells before and after the hydraulic fracturing of the nearby horizontal Marcellus Shale wells. Analyses of samples collected prior to hydraulic fracturing demonstrate that the gas composition, carbon and hydrogen isotope signatures of methane and ethane, oxygen and hydrogen isotope signatures of water, and carbon isotope signatures of dissolved inorganic carbon in the water and gas produced from Upper Devonian sands are different from that produced from the Marcellus Shale. Hence, we propose that spatiotemporal stable isotope monitoring of different water and gas sources before, during, and after hydraulic fracturing can provide insight into possible gas and fluid migrations. The analyses of produced gas and water samples collected post-hydraulic fracturing is currently underway and will be discussed.

Each of the 10 outcrop and 4 core samples was separated into coarse and fine components which were analyzed separately. Samples were prepared using high-purity corundum as an internal standard and X-ray diffraction data were analyzed using RockJock11 software. Illite is present in all examined samples at concentrations ranging from approximately 20 wt% to greater than 60 wt%. Preliminary examination of the illite diffraction suggests that there are few if any smectite layers present. On the other hand, chlorite is present in some samples and absent in others. Calcite also varies widely from below the detection limit to greater than 50 wt%. Dolomite is present at trace concentrations. Quartz varies from roughly 20 wt% to more than 35 wt%. As an independent check on the presence of expandable layers in the clay-fraction of the samples, cation exchange capacity (CEC) was measured using UV-VIS spectrophotometry of a copper complex (Cu-ethylenediamine) which adsorbs strongly to the exchange sites present in the sample. CEC values from the Marcellus Shale are within the typical ranges of kaolinite and illite and are consistent with the absence of smectite.

Formation water from conventional oil and gas production is usually from sandstone or carbonate. Produced waters from shale hydraulic fracturing provide a new opportunity for understanding water-rock interaction in shale reservoir rocks. We used multi-collector ICP-MS to determine the stable isotope ratio of lithium in formation waters from conventional oil and gas reservoirs in the Gulf Coast Sedimentary Basin (GCSB), and in produced waters from hydraulically fractured shales of the Middle and Upper Devonian Marcellus Formation in the northern Appalachian Basin in Pennsylvania. Marcellus produced waters and some GCSB formation waters contain elevated Li/Cl*10,000 ( approximately 10 to 15 vs. <1 to approximately 12 for other oil-and-gas-associated waters and seawater) as well as elevated Li/Mg and Br/Cl. For most fluids analyzed, delta 7Li varies approximately inversely with concentration, similar to other published data for formation waters. The delta 7Li of the shale fluids analyzed ranges from approximately 8 to 13 per mil, much lighter than average seawater ( approximately NE31 per mil), and cluster at the lowest delta 7Li and highest Li concentrations of formation waters published so far. One sample of GCSB formation water has an anomalously low concentration of Li for its delta 7Li value, possibly due to contribution of clay dehydration water. The deep-basin settings of the Marcellus produced-water and GCSB formation water suggest strong influence on Li from clay minerals because clays are the probably the largest reservoir of Li. Previously published experiments on smectite-to-illite transformation, an important diagenetic reaction in sedimentary basins, suggest that fluids should be isotopically heavier than the transformed illite and that Li should partition into the clays. If seawater or evaporated seawater are buried with the sediments, then produced waters should have delta 7Li heavier than seawater, not lighter, and total Li concentration should be lower. Our data suggest that either the experimental data do not represent in situ processes, or that there is another source of isotopically light Li being added to pore water in sedimentary basins.

We have analyzed Marcellus ES&H incidents reported by Pennsylvania Department of Environmental Protection between 2008 and 2011. PA DEP incident reports were categorized from administrative to severe along a five point scale. Administrative incidents, classified as incorrect permits, improper signage, etc., were excluded from analysis. Of the 35 counties with active drilling during the study period, eight had no incidents reported, and the overall number of reported incidents decreased between 2008 and 2011. Although the overall reporting rate declined over the study period, reports of significant and serious incidents increased in 74% of counties. This increase may not necessarily reflect a growth in serious ES&H violations, because simultaneous changes in inspection and reporting practices in Pennsylvania may have changed detection efficiency. Reporting rates were examined in the context of the regulatory environment, including changes in inspection effort, inspection practices, and public awareness of Marcellus drilling activities, to assess whether the observed trends may be confounded by these processes. Benefits of understanding Marcellus ES&H incident reporting in Pennsylvania include identification of engineering and operational risks, and the promotion of public confidence in shale gas development practices.

Current practices employ large volumes of water with chemical additives, and also result in the production of flowback waters that require treatment before reuse or disposal. An understanding of changes in fluid chemistry due to fracturing fluid-shale reactions provides direct input for reservoir design, and also may guide development of strategies for managing and disposal of solid and liquid wastes. In this study we investigated Marcellus Shale metal extractability and reactivity with fracturing fluids through bulk extractions, and fracture fluid-shale reactions in high pressure, high temperature autoclave systems. The primary goals for this study are to evaluate the role of shale-fluid reactions on controlling flowback water chemistry, and to evaluate the potential for metals to be extracted from organic-rich shales under various environmental conditions. Metal extractability studies focused on Marcellus Shale core and outcrop powders and rock chips were performed under different temperature and pressure conditions with a variety of extractants. Reactions between synthetic fracturing fluids (designed based on information from FracFocus) and Marcellus Shale core are ongoing in high pressure, high temperature autoclave systems to evaluate changes to both trace element and total dissolved solids composition of the fluid, and changes to rock morphology and mineralogy, over time. Experimental results will be used to identify the primary solid phases controlling changes to fluid chemistry. Our results to date show that, despite no statistical differences in trace metal concentrations in core and outcrop samples, extractability varies as a function of sample type and, generally, metal extractability is higher in outcrop samples. For example, in batch extractions using powdered rock samples the extractability of U by oxidation of the organic matter with H (sub 2) O (sub 2) is higher in outcrops ( approximately 10%) compared to cores ( approximately 0%) . For our rocking autoclave experiments, we anticipate that reactions between synthetic fracturing fluid and natural carbonate and clay minerals present in our samples will result in observable geochemical changes. Ongoing studies will 1) determine the rate of metal leaching and the influence of increased surface area on metal extractability, and 2) identify the primary reactions that occur between fracturing fluids and shales.

Reservoir storage capacities and long-term security of geologic carbon sequestration will be dependent on the trapping mechanisms and mineral transformation in the deep subsurface. A critical need exists to understand the evolution of microbial populations that influence the biogeochemistry in these reservoirs. As the CO (sub 2) front moves through the storage aquifer, microbial communities may preside in residual brine left behind in cracks, dead flow zones, and upstream to the front; this brine will have a gradient of dissolved CO (sub 2) concentration. The evolution of microbial ecology along this CO (sub 2) concentration gradient was investigated using fluid-slurry samples obtained from a proposed carbon sequestration site. The native species of these samples were investigated with varying pCO (sub 2) from 0% to 100% under reservoir temperature and pressure for up to 56 days. Microbial growth occurred with 0% and 1% pCO (sub 2) , while microbial population decreased by four orders of magnitude with 10% and 100% pCO (sub 2) . This suggests that any biological processes that may have been involved in the security of the reservoir pre-CO (sub 2) -injection will be hindered near the CO (sub 2) plume, but may be important where CO (sub 2) is attenuated. Batch reactors with 0% pCO (sub 2) , but lowered pH had increased microbial population by one order of magnitude, suggesting that microbial shifts will occur even in highly buffered reservoirs due to exposure to CO (sub 2) . Halotolerant microorganisms Halomonas and Marinobacter were the most tolerant to the conditions that would follow CO (sub 2) injection. Findings provide insight into the populations that may survive in the deep subsurface following the supercritical fronts. These populations will eventually give rise to the community that will impact the trapping mechanisms, storage capacities, and long-term security of the CO (sub 2) deposits. Knowledge of the surviving microbial populations will enable improved models for predicting the fate of CO (sub 2) following injection and lead to better strategies for ensuring the security of CO (sub 2) in the subsurface.

The Marcellus Shale Test Site comprises eight Marcellus Shale wells (six horizontal wells and two vertical wells) at 8100-8200 ft total vertical depth. All six horizontal wells were drilled from one pad: three wells were drilled northwest and three were drilled southeast. Two existing vertical Marcellus Shale wells were optimally located to serve as microseismic monitoring wells during hydraulic fracturing; one vertical well was located amidst the three northwestern horizontal wells while the second vertical well was located amidst the three southeastern horizontal wells. During hydraulic fracturing, eight wireline geophone tools spaced 100 ft apart were deployed in the vertical Marcellus Shale well that was nearest to the horizontal wells being completed. The two lowermost geophones were located in the Hamilton Formation, above the Marcellus Shale but below the Tully Limestone; the upper six geophones were located in shale formations above the Tully Limestone. Microseismic data were acquired during the pumping of 56 stages; more than 10,000 microseismic events were located. This study's objective is to examine the upward growth of fractures during hydraulic fracturing and is primarily focused on microseismic events located above the Tully Limestone. Such events were observed during the pumping of all stages of all wells. Most events above the Tully Limestone were observed during the pumping of the northwestern wells where events were clustered along two near-vertical planes with azimuths of about 10 degrees and 50 degrees . Microseismic event clusters attained a maximum height of 1920 ft above the Marcellus Shale, which coincides with the maximum height of faults in the area as interpreted from 3-D surface seismic. For the southeastern wells, microseismic events above the Tully Limestone were infrequent and scattered; no event clusters were observed. Microseismic results indicate a maximum fracture height growth of about 1900 ft upward to a depth of about 6200 ft at this location. More than 5500 ft of strata separate the uppermost created fracture from the nearest drinking water aquifer.

In this project we are looking for artifacts of hydrate occurrence in marine sediment cores to better understand their formation, source, and distribution in sediment. Currently, no artifacts of natural gas hydrate have been identified for standard sediment cores, aside from pore water salinity measurements collected shortly after core recovery. In marine muds natural gas hydrate occur as fractures and veins which dissociate during core removal. We hypothesize that the dissociating gas hydrate may leave behind physical and chemical artifacts in sediment cores such as fractures, tunnels, carbon isotope anomalies, salinity variability in areas surrounding fractures, as well as mineralization artifacts such as pyrite and calcite precipitation resulting from the biogeochemical transformation of methane. Cores used in this project are from the Gulf of Mexico Gas Hydrate Join Industry Project Leg 1, collected in Hole KC151-2 in Keathley Canyon Block 151. We examined the interior of the core for fractures using x-ray computed tomography. In situ gas hydrate filled fractures have been observed on logging-while-drilling resistivity images in Keathley Canyon; these fractures are near vertical with apertures on the millimeter-scale. Similar near-vertical fractures have been attributed to gas hydrate rather than fractures formed during the removal process. These fractures were sampled for carbon isotope analysis using a Picarro CO (sub 2) elemental analyzer to measure delta (super 13) C of organic and total carbon present and compare these data with carbon isotope data from un-fractured core sections. Preliminary results indicate an isotopically light ratio of -21 to -31 consistent with marine alga. Other samples will be collected from the potential hydrate fractures for wet chemistry analysis to compare salinity levels of the fracture surface versus the background salinity level for Hole KC151-2. We hypothesize this will be markedly different as the dissociating hydrate will flush the fracture with fresh water. Further samples will be taken from the core surrounding the fractures and from cores that do not contain hydrate fractures to analyze the mineralization artifacts present using the scanning electron microscope. We hope to develop a set of criteria that can be used to identify former occurrence of natural gas hydrate in sediment core.

Two wells (KGS 1-32 and 1-28) have been drilled to provide data for site specific determination of the storage potential of the Arbuckle. Cores from specific depths within Arbuckle (4164'-5130') were utilized for study and flow-through experiments. Examination of formation rocks by thin section studies, SEM, XRD and CT scans were carried out to characterize the mineralogy of the cores. Dominant mineralogy throughout the formation is dolomite with sporadic large chert nodules and occasional zones of argillaceous and pyritic minerals. Silica occurs as authigenic megaquartz, radial chalcedony, microcrystalline quartz and porous silica. Carbonate-silica contacts contain extensive heterogeneity with sulfide minerals and argillaceous material in between. Extensive vugs and microfractures are common. This study focuses on three zones of interest: Mississippian pay zone (3670'-3700'), potential baffle in Arbuckle (4400'-4550') and proposed CO (sub 2) injection zone (4900'-5050'). Drill stem tests and swabbed brine samples collected from 13 depths throughout the aquifer reveal a saline brine ( approximately 50,000-190,000 TDS) dominated by Na (super +) , Ca (super 2+) and Cl (super -) . Elemental ratios of major cations with Cl (super -) demonstrate a typical saline aquifer system. Ca/Cl and Mg/Cl ratios suggest effect of dolomitization within the brines. Cl/Br ratios reveal hydrochemical separation of the upper and lower Arbuckle and delta (super 18) O and delta (super 2) H isotopes and Li/Cl ratios support the separation of upper and lower Arbuckle by a baffle zone. Swabbed waters provide Fe speciation data and reveal the importance of it in the system. Laboratory experiments carried out at 40 degrees C and 2100 psi using formation core plug and collected brine identify reaction pathways to be anticipated when supercritical CO (sub 2) is injected. Results showed varying concentrations of elements with Ca (super 2+) , Mg (super 2+) , Na (super +) and Cl (super -) increasing during the first 15 hours, while Fe, S, and SO (sub 4) (super 2-) decrease. For the next 15 hours a reverse trend of the same elements was observed. Alkalinity and pH show inverse relationship throughout the experiment. We conclude that dominant reactions will occur between brine, CO (sub 2) and dolomite, calcite, chert, pyrite and argillaceous minerals. There is no perceived threat to freshwater resources in Kansas due to CO (sub 2) injection.

High sodium adsorption ratios (SAR) of the waters could degrade agricultural land, especially if directly applied to soil surface. One method of disposing of the produced water, while deriving beneficial use, is subsurface drip irrigation (SDI), where acidified CBM waters are applied year-round to cropland via buried tubing (0.92 m below ground surface). This research examined the impacts to soil chemistry and shallow groundwater resulting from 3 years of SDI operation at a study site in Johnson County, Wyoming. The site spreads across an alluvial terrace system where depth to groundwater is generally shallow ( approximately 3 m). Excess irrigation water led to a rising water table, and even temporarily reached the depth of drip tubing. The rise corresponded to increasing groundwater salinity in some wells. Native magnesium-, sodium- and sulfate-bearing salts in soil contributed more to increased groundwater salinity than evaporated CBM water. Native salts have a laterally heterogeneous distribution in soils but redistribution by rising groundwater generates a more homogenous environment. Solutes in soil were also redistributed vertically, resulting in greatest salt concentrations in soil between drip tubing and the water table due to restricted drainage and root water uptake. Importantly, maximum soil SAR occurred around 0.75 m depth and little increase has occurred at the soil surface, illustrating natural buffering of the system.

The chemistry of the returning waters reflects the original composition of the injection fluid, constituents in the shale formation that were mobilized by the fluid, and the co-mingled formation waters liberated by hydraulic fracturing. Previous work (Chapman et al., 2012, Env. Sci. Technol. 46, 3545-3553) demonstrated that the Sr isotope compositions of Marcellus formation waters collected over a distance of approximately 375 km fall within a relatively small range (0.7101-0.7121), providing a unique signature for interaction of Marcellus produced water with surface and ground waters. Strontium concentrations and isotope compositions are controlled primarily by mixing with formation waters, which contain very high levels of Sr (up to 5000 ppm), but other chemical species vary depending on the content of the fracturing fluid, shale, and formation water. We will report strontium isotope and geochemical data from several horizontally drilled wells in the Marcellus Formation, with a focus on the changes in chemistry and isotope composition over time as the returned waters shift from mixed injection fluids and formation waters to predominantly formation waters. Returned waters from four wells in southwestern Pennsylvania demonstrate that the Sr isotope composition reaches a constant value within 2-10 days of water return, while the Sr concentration rises more slowly and appears to hit a steady state value within 30 days. As production continues the returned waters primarily reflect the formation water end-member, allowing better understanding of shale water chemistry and evolution.

However, fluid/rock reactions during HF may lead to changes in produced water chemistry such as an increase in total dissolved solids (TDS). Sr isotopes are an effective tool for differentiating Marcellus Shale derived-fluids from other high TDS sources (Chapman et al. 2012, doi: 10.1021/es204005g), but questions remain as to what controls Sr concentrations and isotopic values in Marcellus Shale fluids. Here, we present Sr isotopic data from Marcellus Shale dissolution experiments using synthetic brines and HF fluids. A core sample of Marcellus Shale from Greene County, PA was crushed and placed into a high P and T reaction vessel. Solutions were added in two different experiments: one with synthetic brine, and another using brine+HF fluid. The HF fluid was made up of components listed on fracfocus.org. Experiments were run for approximately 16 days at 27.5 MPa and 130 degrees C. Aqueous samples were periodically removed for analysis and Sr isotope ratios were measured by MC-ICP-MS. Using just brine, the pH decreased from 7.6 to 5.3 after 24 hrs, but then became steady at approximately 6.1. Sr (aq) concentrations started at 2.5 mmol/L after 24 hrs and then rose to approximately 3 mmol/L over approximately 380 hours. During this time only 6% of the total inorganic carbon (TIC) dissolved from the shale. The epsilon Sr values (deviation of the (super 87) Sr/ (super 86) Sr ratio from that of seawater in parts per ten thousand) started at +43.2 and decreased to +42.4. In the experiment using brine+HF fluid, the pH rose from 1.8 to 5.6 by day six. Sr concentrations were higher after approximately 24 hours (3.9 mmol/L) and increased to 4.5 mmol/L by the end on day 16. Over 60% of the TIC dissolved from the shale during the reaction. The epsilon Sr started at +36.5 at 24 hours and decreased to +35.5 by the end. Differences in the Sr isotopic results between the experiments, in combination with the TIC data, suggest the presence of at least two distinct Sr reservoirs in the sample: 1) water-soluble or exchangeable Sr, and 2) Sr incorporated into carbonate minerals. The lower epsilon Sr values using brine+HF fluid may be explained by the increased dissolution of carbonates. These results suggest that carbonate minerals within the Marcellus Shale may help control Sr isotopic composition of produced waters from these formations.

Previous studies have identified that trace metals are present in the Marcellus shale in core and outcrop materials. Little work has been done evaluating fine-grained drill cuttings from the Marcellus, and the geochemical signals that might result under environmental conditions at the earth's surface and under landfill conditions. Leaching studies were performed along with characterization of the solids to help identify potential trace metal point-sources. Samples of drill cuttings from two different locales in Pennsylvania (Southwestern PA and North Central PA) were evaluated. Drill cuttings represent the fine grained rock pieces that are broken away from the formation by the action of the drill bit and often include remnants of various types of drilling fluids (e.g. water-based, and nonwater based) and additives despite rinsing in the field. The additives may vary greatly between sites. The drill cutting solids were analyzed via X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The SW PA site utilized nonwater based drill cuttings and analysis of the solids show an abundance of barite in addition to the typical shale mineralogy of quartz, clay, calcite and pyrite. The NC PA samples did not contain barite, but contained added salts. The dried drill cuttings were leached with DI water in different L:S ratios, and under various pH conditions. In addition, the drill cuttings were exposed to both synthetic rain water and natural rain water collected in the Pittsburgh area. TCLP and sequential extractions are underway. The natural pH of the solids from both locales were alkaline ( approximately 9.0-9.4), and both samples show a high buffering capacity. There was a marked color difference between leachates from the nonwater based drill cuttings versus the water based drill cuttings. The potential influence of organic compounds and overall geochemical trends at different pH are being evaluated for both non-water based and water-based drill cuttings.

A key element of the program, which is important in advancing geologic carbon storage technology towards commercialization, involves small and large scale field tests being carried out through the Regional Carbon Sequestration Partnerships (RCSPs) initiative. These tests highlight DOE's awareness of the importance of addressing CO (sub 2) mitigation on a regional level to most effectively manage differences in geology, climate, population density, infrastructure, and socioeconomic development. Regarding differences in geology, the depositional environment has a major influence on the properties and architecture of reservoirs, affecting how CO (sub 2) is trapped, and how it moves and interacts with other formation fluids and solids. The effectiveness of CO (sub 2) injection and storage and the ability of technologies to monitor and simulate storage will differ among depositional environments. This paper summarizes lessons learned to date from DOE's field testing in a variety of depositional environments. The Storage Program is considering 11 different classes of geologic formations, based on depositional environment, as having potential for storage. The RCSPs have completed 18 small scale field projects involving CO (sub 2) injection into eight of the 11 classes; one small scale test in basalt is on-going. Eight projects were in oil and gas fields; five in saline formations; and five in unmineable coal seams. Currently, under the RCSP initiative, a number of large-scale (1 million metric tons CO (sub 2) injected) field projects are underway in regionally significant geologic formations representing six different depositional environments, focusing on saline formations and oil fields.

The Marcellus is a variably calcareous shale with intercalated limestone. Based on core extracted in Greene County, southwestern Pennsylvania, uranium (U) concentrations in Marcellus Formation samples range from 3 to 47 ppm. Sequential extraction experiments indicate that 30 to 95% of the U is held in the silicate fraction. Although there is a positive correlation of whole rock U concentration with TOC as observed by others, U associated with the oxidizable (organic) fraction contributes less than 25% (and usually <10%) of the total. Up to 64% of the U was found in the 1.0 N acetic acid leachate, which has implications for uranium release into the environment from relatively soluble carbonate minerals in drilling waste. The source of NORM in Marcellus produced water is primarily radium [1], the daughter product of U and Th. The low U concentrations measured in produced water samples from three Marcellus Shale gas wells (0.1 to 0.5 mu g/L) may result from U reduction and precipitation as UO (sub 2) or U (sub 3) O (sub 8) , consistent with relatively high Mn (super 2+) (1-8 g/L) and Fe (super 2+) (20-120 g/L) concentrations. (super 238) U/ (super 235) U ratios of Marcellus shale obtained by MC-ICPMS using the double spike method fell in a narrow range of 137.80 to 137.85, similar to other black shales. (super 238) U/ (super 235) U ratios in the carbonate fraction of calcareous shale units were in the range of marine carbonate; however carbonate cements extracted from black shale units were isotopically heavier by an average of 0.7 ppm. (super 238) U/ (super 235) U ratios in the organic matter and silicate fractions generally overlap and are lower than coexisting carbonate cement by about 0.3 ppm.

Preliminary experiments on metal mobilization on carbonate rocks upon contact with CO (sub 2) -saturated brine have indicated arsenic release in excess of the U.S. EPA standards for drinking water. The most common sources of arsenic in sedimentary geologic formations are arsenopyrite (FeAsS) and arsenian pyrite. This study aims to determine the maximum long-term dissolution rates of arsenopyrite under a range of conditions representative of deep and shallow geologic formations. For this purpose, a small-scale flow-through system was developed and used to simulate the dissolution of arsenopyrite under a wide range of temperature, pressure and solution chemistry conditions. The effects of flow rate, pressure and different oxidants on arsenopyrite were separately tested. The dissolution studies focused on determining the mineral dissolution rate based on total As release with the system at steady state operation. However, measurements of Fe and S were also collected for comparison with previous studies. The dissolution rate computed from steady state As concentrations resulting from reaction of the mineral with 10 (super -4) M Fe (super 3+) as oxidizing agent at ambient conditions was 10 (super -8.3) mol/m (super 2) s, which is comparable to reported rates of arsenopyrite dissolution rates under similar conditions.

Dissolution of minerals induces the release of various metals that may participate in subsequent dissolution and precipitation reactions, and that may be of concern if reacted formation fluids migrate out of the target storage zone. The objective of this study is to study the release of As and Fe, present in the reservoir and cap rocks of the Lower Tuscaloosa reservoir. XANES analysis of the samples indicated a relationship between As and Fe in these samples. To assess the potential release of As and Fe, and to measure the effect of CO (sub 2) on their release rates, dissolution experiments were conducted with caprock and reservoir rock samples obtained at different depths. The dissolution was studied at representative conditions of the reservoir (i.e. 60 degrees C, 100 bars, synthetic brine of 1.4M NaCl) utilizing a small-scale flow-through system. The dissolution was conducted with deoxygenated 1.4M NaCl solution for 10 hours prior to CO (sub 2) injection into the NaCl solution. The solution chemistry was defined pre- and post-CO (sub 2) injection by ICP-MS analysis. Accordingly, rock samples were analyzed pre- and post-CO (sub 2) injection by XRD and SEM. Preliminary dissolution experiments showed that upon CO (sub 2) injection, rates of metal release increased significantly before reaching a new equilibrium (Figure 1). Figure 1.

It is not well known how very high levels of electrolytes influence the solubility of hydrocarbons. The objective of this study is to determine if existing salting-out parameters, called Setschenow constants, are applicable to predict the decrease in aqueous solubility of petroleum hydrocarbons, including polycyclic aromatics hydrocarbons (PAHs), phenols, and thiophenes, due to high levels of electrolytes in concentrated oilfield brines. We measured the solubility of important organic compounds found in oilfield brines, such as naphthalene. Electrolytes studied include NaCl and CaCl (sub 2) , which are the most common salts found in oilfield brines (1). The organic compounds in the brines were extracted with a 100 mu m polydimethylsiloxane (PDMS) fiber using solid phase microextraction (SPME) and analyzed by an Agilent 6890 gas chromatograph coupled with a flame ionization detector (GC-FID). We hypothesize that existing Setschenow constants measured at lower ionic strengths (e.g. up to seawater) will also predict the salting-out effect at very high ionic strengths expected in brines (5M) for a range of compound classes of interest. These results are expected to have implications for enhanced oil recovery, CCUS, and any other industry that deals with produced waters. If valid, the solubility of these compounds can be readily modeled using existing Setchenow constants determined at lower ionic strengths.

The interpretation incorporated geophysical logs from 38 wells located in a 23km (super 2) area surrounding the pilot site, which lies near the southern edge of the high rate Fruitland coal production fairway located along the axis of the San Juan Basin. Log interpretations revealed three coal-bearing zones (upper, middle and lower) within the Fruitland Formation that are approximately 7, 4.7 and 8.5m (23, 15.5 and 28ft) thick, respectively. The interpretations indicate that each of these coal zones is split by a parting into upper and lower beds making a total of six mappable coal beds in the area surrounding the CO (sub 2) injection well. The combined thickness of the upper two coal beds in the upper coal zone varies between 3.5 and 4.8m (11.5 to 15.7ft); and that of the middle beds, from 2 to 4.3m (6.6 to 14.1ft) thick. The thickness of the individual coal beds in the lower coal zone varies from about 2.7 to 4.25m (9 to 14ft) for the upper bed and from about 3 to 5.5m (10 to 18ft) for the basal coal bed. Partings separating the upper and lower coal beds in each zone are on average about 2m (7ft) in the upper and middle zones; and about 1m (3.5ft) in the lower zone. Seismic response of the upper, middle and lower coal zones was interpreted and correlated through the 23km (super 2) area. The stratigraphic complexity of this coalbed methane reservoir is also accompanied by considerable structural disharmony between the three coal zones. The reservoir complexity revealed in this study may account for lower than expected CO (sub 2) injectivity and preferential injection into the lower coal zone during the pilot test.

There is also evidence for carbonate formation supported by fluids that have been modified by reactions with the incoming Juan de Fuca Plate ( (super 87) Sr/ (super 86) Sr=0.7071; Teichert et al., 2005) or with terrigenous turbidites ( (super 87) Sr/ (super 86) Sr=0.70975 to 0.71279; Sample et al., 1993). We report on the strontium isotopic composition of carbonates and fluids from IODP Site U1329 and nearby Barkley Canyon (offshore Vancouver Island), which have strontium isotope ratios as low as 0.70539. Whereas the strontium and oxygen isotopic compositions of carbonates from paleoseeps in the uplifted Coast Range forearc indicate formation in ambient bottom seawater, several samples from the Pysht/Sooke Fm. show a (super 87) Sr-depleted signal ( (super 87) Sr/ (super 86) Sr=0.70494 and 0.70511) similar to that of the anomalous Site U1329 and Barkley Canyon carbonates. Our data, when analyzed in the context of published elemental and isotopic composition of these carbonates (Joseph et al., 2012), point to two formation mechanisms: 1) shallow precipitation driven by the anaerobic oxidation of methane (AOM) with delta (super 13) C values as low as -50 ppm and contemporaneous (super 87) Sr/ (super 86) Sr seawater ratios, and 2) carbonate precipitation driven by fluids that have circulated through the oceanic crust, which are depleted in (super 87) Sr. Carbonates formed from the second mechanism precipitate both at depth and at sites of deep-sourced fluid seepage on the seafloor. The (super 87) Sr-depleted carbonates and pore fluids found at Barkley Canyon represent migration of a deep, exotic fluid similar to that found in high permeability conglomerate layers at 188mbsf of Site U1329, and which may have fed paleoseeps in the Pysht/Sooke Fm. These exotic fluids likely reflect interaction with the 52-57Ma igneous Crescent Terrane, which supplies fluids with high calcium, manganese and strontium enriched in the non-radiogenic nucleide. Tectonic compression and dehydration reactions then force these fluids updip, where they pick up the thermogenic hydrocarbons and (super 13) C-enriched dissolved inorganic carbon that are manifested in fluids and carbonates sampled at Barkley Canyon and at Site U1329. The Crescent Terrane may have sourced cold seeps in this margin since at least the late Oligocene. Abstract Copyright (2012) Elsevier, B.V.

However, numerous inputs to the watershed, including legacy and ongoing coal, oil and gas production, as well as rural and industrial sources present challenges to the accurate identification of contaminant sources and the assessment of their impact on water quality. We have initiated a strontium (Sr) isotopic and geochemical study of the Allegheny River watershed in western Pennsylvania. Sr isotopes are a sensitive tracer that can distinguish between contaminant sources such as Marcellus derived produced waters, abandoned coal mine drainage (AMD), fluids from conventional Upper Devonian gas reservoirs, and fly ash impoundments. Preliminary results from analyses of stream water collected from approximately 45 sites along the length of the Allegheny River and seven of its tributaries show that Sr varies across the watershed with lower concentrations (mean [Sr] = 82 ppb) in the upper reaches and tributaries, and increasing concentrations downstream, reaching approximately 200 ppb near Pittsburgh, where the Allegheny River enters the Ohio River. Anomalous Sr concentrations are observed in two creeks in the eastern portion of the watershed, where Sr concentrations reach as high as 2.5 ppm and 1.3 ppm respectively. Preliminary Sr isotope data indicate that most of the Allegheny River and its tributaries cluster around a narrow range of (super 87) Sr/ (super 86) Sr values, from 0.7125 to 0.7130 (epsilon (super Sr) (sub sw) = +47.3 to +53.8, where epsilon (super Sr) (sub sw) is the deviation of the (super 87) Sr/ (super 86) Sr ratio from that of seawater in parts per ten thousand). However, both higher (up to +62.2) and lower (down to +35.2) epsilon (super Sr) (sub sw) values are observed in the two tributaries with the elevated Sr concentrations. While Sr concentrations are likely to vary across the watershed due to differences in silicate and carbonate sources (as indicated by Mg/Na and Ca/Na ratios) the observed patterns of anomalous Sr concentrations and large deviations in epsilon (super Sr) (sub sw) suggest non-weathering sources. A full set of geochemical data and multiple season sampling will be required to characterize and identify these sources.

The large scale implementation of CCS mandates better understanding of the risks associated with CO2 injection, especially in regards to potential leakage of the stored CO2. Organics, in the residual oil and dissolved in the brine, can partition into supercritical CO2 (sc-CO2) and move with that phase if it leaks. This review presents an overview of the thermodynamic models and trends in experimental partitioning data needed to understand what compounds may be expected to move with the sc-CO2. There are two main types of thermodynamic models used for predicting the solubility of organic compounds in sc-CO2, equations of state and quantitative structure activity relationships. Both can predict the partitioning behavior of one compound in sc-CO2, however only equations of state can predict solubility in multicomponent systems. In addition, equations of state have been developed to determine the effect of electrolytes on the partitioning behavior of organics dissolved in brines. There are three main trends in the partitioning behavior of organics in sc-CO2: Pure phase solubility follows trends in vapor pressure; compounds with higher volatility have higher solubility in sc-CO2. Second, the partitioning from water to sc-CO2 follows trends in Henry's constants, which follow the relative solubility of a compound in both the sc-CO2 and aqueous phases. Thirdly, the solubility of a compound can be enhanced by the presence of another; highly volatile compounds enhance the solubility of compounds with lower volatility. Finally, the review presents the gaps in experimental research that can be used to improve the modeling of the partitioning behavior of organics in sc-CO2, specifically in regards to co-solvency effects and the effects of electrolytes on the partitioning of dissolved organic compounds between oilfield brines and sc-CO2.

Simulated experimental downhole conditions include a pressure of 28.6 MPa and a temperature of 50 degrees C. Brine composition was formulated from the NETL NATCARB database, resulting in a simple solution of 1 M (NaCl, MgCl (sub 2) , CaCl (sub 2) ). It was determined that the brine chemistry plays a vital role in determining the degree and type of alteration of cement in carbon sequestration conditions. The implications of co-sequestration (CO (sub 2) /O (sub 2) /SO (sub 2) mixtures) from of oxy-fueled combustion, coal gasification and sour gas have been considered. Geochemical modeling was conducted to understand the interaction between formation brine, cement and co-contaminant gases, using a gas composition of 95.5% CO (sub 2) , 4% O (sub 2) , and 1.5% SO (sub 2) . The modeling results are significant in determining the validity of co-sequestering coal flue gas containing SOx gases or sour hydrocarbon gas which could potentially produce pyrite or other sulfur-bearing species in the cement via mineralization trapping. Thermodynamic components of aqueous species, gases, and minerals were used to calculate the pH and mineral saturation indices using CHIM-XPT. The computed pH of the solution is 4.34. The total sulfate molality within the brine is 0.0095 M. In experimental conditions of 600 mL of brine, 0.0057 moles of sulfate will be converted into 5.7 mL of sulfuric acid. The modeling shows that an excess of 31% O (sub 2) forms, indicating that H (sub 2) S from SO (sub 2) disporportionation is oxidized to sulfate, thus no gaseous H (sub 2) S will form. Remaining SO (sub 2) in the experimental headspace has a predicted mole fraction is 10 (super -46) . Additional SO (sub 2) gas added to the system produces the reaction to precipitate gypsum. Additional gas reactions precipitate gypsum, anhydrite, calcite, and dolomite.

Single phase and multiphase fluid flow models coupled with a geomechanical model were used to determine the pressure response, overburden ground movements, and CO2 leakage rate. Several different hypothetical fracture/fault scenarios were considered to study the influence of a fracture, fracture location, and fracture permeability. The injection of CO2 could increase the reservoir pressure and may lead to activation of an existing dormant fracture/fault present in the overburden caprock layer. The activation of this dormant fracture or fault may cause changes in fluid pressure, CO2 plume migration and ground deformations. In this study, a hypothetical CO2 injection scenario with the activation of a caprock fracture was considered. Results on the pressure changes, plume migration, leakage rate and overburden ground movements are presented in this paper. Results show that the pressure signature at a point in a monitoring overburden layer is distinctly different in the presence of a caprock fracture. Also, a change in the pressure signature at a given time is an indication of fracture activation. Results from the fluid flow model, both single-phase and multiphase, coupled with a geomechanical model show that ground deformation patterns may also be useful in identifying fracture activation and in developing geophysical monitoring technologies.

Several challenges must be overcome, however, to enable the routine use of isotopic tracers, including the ability to rapidly analyze numerous aqueous samples with potentially complex chemical compositions. In a field situation, it might be necessary to analyze tens of samples over a short period of time to identify subsurface reactions and respond to unexpected fluid movement in the host formation. These conditions require streamlined Sr separation chemistry for samples ranging from pristine groundwaters to those containing high total dissolved solids, followed by rapid measurement of isotope ratios with high analytical precision. We have optimized Sr separation chemistry and MC-ICP-MS methods to provide rapid and precise measurements of isotope ratios in geologic, hydrologic, and environmental samples. These improvements will allow an operator to independently prepare samples for Sr isotope analysis off-site using fast, low cost chemical separation procedures and commercially available components. Existing vacuum-assisted Sr separation procedures were modified by using inexpensive disposable parts to eliminate cross contamination. Experimental results indicate that the modified columns provide excellent separation of Sr from chemically complex samples and that Sr can be effectively isolated from problematic matrix elements (e.g., Ca, Ba, K) associated with oilfield brines and formation waters. The separation procedure is designed for high sample throughput in which batches of 24 samples can be processed in approximately 2 hours, and are ready for Sr isotope measurements by MC-ICP-MS immediately after collection from the columns. Precise Sr isotope results can be achieved by MC-ICP-MS with a throughput of 4 to 5 samples per hour. Our mean measured value of NIST Sr isotope standard SRM 987 is 0.710265 + or - 0.000014 (2sigma , n=94). A range of brines and CO (sub 2) -rich fluids analyzed by this method yielded results within the analytical uncertainty of (super 87) Sr/ (super 86) Sr ratios previously determined by standard column separation and thermal ionization mass spectrometry. This method provides a fast and effective way to use Sr isotopes for monitoring purposes related to geological CO (sub 2) storage.

Microorganisms are numerous in the subsurface and may play a pivotal role in the sequestration of CO (sub 2) . The Wallula pilot well in Eastern Washington state provided the opportunity to investigate how a native microbial community will respond to the injection of supercritical CO (sub 2) (scCO (sub 2) ) into basalt. Formation water from the depth of planned CO (sub 2) sequestration was used to inoculate basalt cores contained in pressure vessels maintained at the temperature (35 degrees C) and pressure (82.7 bar) of the sequestration interval and then the cores were exposed to scCO (sub 2) for as long as 146 days. Petrographic and scanning electron microscopy (SEM) analyses revealed the presence of thick ferro-magnesium carbonate lining the vugs in basalts exposed to scCO (sub 2) and microorganisms. SEM analysis also demonstrated the presence of possible biofilms within the fissures of the basalt core. Molecular analyses showed that microbes survived the scCO (sub 2) exposure and that cell numbers slowly increased over time after the initial exposure to scCO (sub 2) . Microbial community analysis revealed a shift in the community from being initially dominated by Proteobacteria to being dominated by Firmicutes, particularly the genus Alkaliphilus. These results indicate that microbes may assist in sealing fractures in geologic media and suggest the importance of subsurface monitoring of native microbial communities in formation waters exposed to CO (sub 2) during carbon sequestration.

Both private and public entities worldwide rely on CO2 storage potential estimates for broad energy-related government policy and business decisions. High-level estimates of CO2 geologic storage potential, however, have a high degree of uncertainty because the assessments rely on simplifying assumptions due to the deficiency or absence of data from the subsurface associated with areas of potential storage in saline formations and the natural heterogeneity of geologic formations in general, resulting in undefined rock properties. As site characterization progresses to individual CO2 storage sites, additional site-specific data will likely be collected and analyzed that will allow for the refinement of high-level CO2 storage resource estimates and development of CO2 storage capacities. Until such detailed characterization can be documented, dependable high-level CO2 storage estimates are essential to ensure successful widespread deployment of CCUS technologies. Initiatives for assessing CO2 geologic storage potential have been conducted since 1993. Although dependable high-level CO2 storage estimates are essential to ensure successful deployment of CCUS technologies, it is difficult to assess the uncertainty of these estimates without knowing how the current methodologies targeted at high-level CO2 storage resource estimates for saline formations compare to one another. In this study, we compare high-level CO2 methodologies for development of geologic storage estimates for CO2 in saline formations to assess the uncertainty associated with various methodologies.

Increases in TDS of ground or surface waters in the drilling region can potentially be attributed to produced water leakage or improper disposal. However, the Appalachian Basin has a long history of fossil fuel exploration and production that predates the Marcellus Shale gas play, with potential impacts to streams and aquifers from coal mine drainage, fly ash disposal ponds, and brines and drilling-related fluids from shallow legacy gas wells. Multiple geochemical and isotopic tools, along with a detailed understanding of water-rock interaction in the subsurface environment, are needed to sort out the contributions from these different sources. Isotope tracers can add an extra dimension to standard geochemical monitoring tools. For example, we carried out a strontium isotope study of Marcellus produced waters to aid in identification of leakage and verification of safe disposal. In order for the isotope ratio of strontium ( (super 87) Sr/ (super 86) Sr) to be used successfully as a natural tracer in ground and surface waters, the values of the potential endmembers must be distinct. Produced water samples from four counties in Pennsylvania spanning a distance of approximately 375 km yield a relatively restricted range of (super 87) Sr/ (super 86) Sr values from 0.7100 to 0.7121, consistent with leaching experiments on Marcellus Formation drill cuttings. Strontium isotope data from other potential TDS sources over a wide geographic and stratigraphic range, including produced waters from upper Devonian Venango and Bradford sands, indicate that most are isotopically distinct from Marcellus waters, and that influxes from these sources at any given location tend to fall within a fairly narrow range. This demonstrates that the Sr isotope ratio is likely to be a sensitive tracer for verification of safe produced water disposal. Ongoing work includes further development of the Sr, Li, U, and Nd isotope systems to gain insight into water-shale interaction and the geologic history of gas-producing shales, as well as baseline characterization of surface waters in the heart of the Marcellus gas producing region.

However, in coal mining areas of the Appalachians, methane can also originate from shallow gas bearing strata, coalbeds and gas storage fields. Therefore, an increase in methane concentrations cannot always be attributed to Marcellus Shale drilling activity. To understand any methane leaks associated with Shale gas drilling there is a need to 1) understand baseline variations in dissolved methane concentrations, and 2) develop a suite of natural geochemical tracers that can track sources of dissolved methane in the groundwaters and surface waters of the area. In this study, groundwater samples were collected from aquifers overlying Marcellus shale in north-central West Virginia, with no active shale gas drilling in the study area during collection. Samples were analyzed for C and H isotopic signatures and concentrations of dissolved methane, dissolved CO (sub 2) concentrations, and C isotopic signatures of dissolved inorganic carbon. To understand the isotopic compositions of possible sources of methane in study area, samples were collected from producing wells in shallow Devonian sands and Marcellus Shale, deeper gas producing formations, and a coalbed methane well. The isotopic and geochemical data suggests that dissolved methane in the sampled groundwaters is primarily generated by deeper thermogenic sources and/or microbial sources via CO (sub 2) reduction in deeper marine formations. Furthermore, samples with higher methane concentrations do not show a clear correlation with abandoned oil and gas wells, coalbed methane wells and/or abandoned mine lands. We propose that methane from deeper sources is migrating into the sampled groundwater aquifers through natural fractures and faults over geological time scales.

However, hydraulic fracturing of shale to stimulate natural gas, natural gas liquids, and oil production also liberates formation waters, and these waters are co-produced at the well head with the gas and/or liquid products. Produced water from shale formations represents a new opportunity for understanding water-rock interaction in sedimentary rocks. We used quadrupole ICP-MS and multi-collector ICP-MS to determine concentration and isotope ratio of lithium, respectively, in produced waters from hydraulically fractured shales of the Middle Devonian Marcellus Formation from four counties in Pennsylvania spanning 375 km (super 2) . In comparison with existing data from conventional oil and gas reservoir formation waters, the Marcellus produced waters contain elevated Li/Cl * 10,000 ( approximately 10 to 15 vs. <1 to approximately 12). Other ratios (Li/Mg, Br/Cl) are also higher than most formation waters and geothermal fluids. In published analyses of formation waters, delta (super 7) Li varies inversely with concentration. The d (super 7) Li measurements of the shale fluids analyzed for this study ( approximately 6.5 to 11ppm) are much lighter than average seawater ( approximately 31ppm) and cluster at the lowest delta (super 7) Li and highest Li concentrations of formation waters published so far. These geochemical characteristics of Marcellus produced waters suggest strong influence from clay minerals and provide a distinctive and potentially useful diagnostic tracer for contamination investigations.

While accurate measurements can be made in the analytical laboratory, we have developed a rapid, portable technique that can be used to obtain accurate and precise data in the field as well. Sample analysis is completed by mixing 100 mL of water with 10 mL of 1 M sodium citrate buffer (pH approximately 4.5) in a closed system and then measuring the CO (sub 2) in solution using an Anton Paar CarboQC (super TM) carbonation meter. The final pH of the sample-buffer mixture is measured and the DIC is calculated using the measured concentration of [CO (sub 2) ], the temperature-corrected dissociation constants for carbonic acid, the pH, activity coefficients for the carbonate ions, and accounting for the dilution caused by the volume of the buffer. In addition to lowering the pH of the final solution so that most of the DIC has been converted into CO (sub 2) ; the buffer also establishes the same high ionic strength in the mixtures so that the activity coefficients are effectively constant over the entire natural range of DIC tested. Calculated DIC for standard sodium bicarbonate solutions was accurate within 0.5 mM C up to a concentration of 15 mM. In the field, a closed mixing system for water and buffer is accomplished by first collecting the water sample in a 140 mL syringe, after which a smaller syringe is connected to the larger syringe and the buffer injected. In this way, the increased mixed volume is accommodated by movement of the piston in the large syringe, no headspace is generated during mixing, and no CO (sub 2) is lost prior to analysis using the carbonation meter. The method has been tested using alternative buffers (phosphate, phosphate-citrate, acetate) with similar results. The potential interaction between CO (sub 2) and organic buffers has also been evaluated by the addition of varying amounts of methanol (0.05 to 0.5 mL) as an organic modifier. To supplement the testing of known standards, DIC was determined in samples collected from a variety of geochemical settings and compared with laboratory analysis.

The center is designed to meet or exceed green and sustainable building standards and practices: the Living Building Challenge; LEED (super R) Platinum and a 4-star SITES Certification for landscapes. Collaborative scientific research between Phipps and NETL will monitor water quality variables associated with various water management systems on-site. These systems lessen the load on municipal sewage treatment and potable water systems, and include rainwater harvesting, a lagoon system for storm water treatment, a constructed wetland system for sanitary water treatment, rain gardens, green roofs and permeable paving. Chemical analyses of water discharging from each treatment and management operation within the facility are presented that identify the major and minor trace elements associated with each treatment or water management process. Plans for the future collection and analysis of water, sediment and plant samples collected within the water management systems to better indicate system effectiveness over time and space are presented. The efficiency of carbon cycling and capture within the treatment systems will be estimated based on chemical analyses, CO2 respiration, and stable isotope analyses. Plant- and microbe-based treatment processes are expected to vary in effectiveness as a function of seasonal variations in temperature and plant growth. The analysis of selected trace elements and nutrients within the treatment systems will provide more detailed information on the role and rates of biological processes in precipitation, conversion and immobilization of dissolved species of concern. The concentration and fate of water pollutants in treated water used for greenhouse plant watering that may influence plant growth, such as fluoride associated with treated drinking water, will be specifically determined in these analyses.

Accurate assessment of contaminant sources in the watershed, and their impact on the river water quality, is complicated by complexity of inputs such as industrial waste water treatment facilities, legacy acid mine drainage (AMD), oil and gas production, and coal combustion waste sites. Our goal is to establish a baseline for water quality and identify contaminant sources that lead to perturbations to background conditions by combining geochemical and Sr isotopic analysis of daily sampling of Allegheny River water at the Pittsburgh Water Treatment Plant intake with seasonal synoptic measurements across 45 sites within the watershed. Sr isotopes are a natural tracer with the potential to identify inputs to streams from Marcellus produced waters, AMD, and fluids associated with Upper Devonian gas formations in the Allegheny River watershed (Chapman et al. 2012, Env. Sci. Tech. 46:3545). Preliminary results from Allegheny River intake samples over a two month period indicate that Sr concentrations ranged from 140 ppb to 260 ppb, and (super 87) Sr/ (super 86) Sr values ranged from 0.7124 to 0.7127 (epsilon (sub sr) (super sw) = +45.5 to +49.8, where epsilon (sub sr) (super sw) is the deviation of the (super 87) Sr/ (super 86) Sr ratio from that of seawater in parts per ten thousand). In comparison, samples taken in April and July 2012 from seven Allegheny headwater tributaries had lower Sr concentrations (mean approximately 73 ppb; range = 30 to 115 ppb) and epsilon (sub sr) (super sw) values varied from +49.1 and +52.6. Ongoing geochemical and isotopic analysis and additional sampling is underway to identify and quantify contaminant fluxes and model the long-term influence of inputs into the watershed.

This number is well known for many sedimentary rocks under water- and/or oil-saturated conditions. However, due to the difficulty in conducting laboratory tests on supercritical CO (sub 2) -saturated rock because of the specific requirements in terms of pressure and temperature to ensure the supercritical status of CO (sub 2) , this number is not available for a supercritical CO (sub 2) -saturated rock. A finite element method (FEM) approach was developed in an effort to solve this problem. We first calibrated our numerical rock models according to the poroelastic properties of Berea sandstone and Indiana limestone, and conducted a series of numerical tests to measure their Skempton's B coefficients under water-saturated conditions. The test results, which were found to be very close to the laboratory measurements, gave us confidence to extend this testing approach to a CO (sub 2) -saturated rock by changing the pore fluid from water to supercritical CO (sub 2) . The numerical test results showed that the Skempton's B coefficient for supercritical CO (sub 2) -saturated rock is considerably different (lower) than that of water-saturated conditions. This implies that the poromechanical conditions of supercritical CO (sub 2) -saturated rock are significantly different from those of water- or oil-saturated rock, and the change of pore fluids from water/oil to supercritical CO (sub 2) may introduce a significant change in the poromechanical properties of the rock.

Despite its location near the base of a talus slope, the cave demonstrated the thermal characteristics of an apparently static cave, with limited connections to the external environment other than through the cave entrance. Congelation ice that lasted until late spring formed as drip or flowstone and ponded ice from the limited influx of infiltrating water during late winter/early spring. A closed period of thermal stratification and slow warming of cave air was followed by an open period in winter months during which the cave was cooled by the influx of cold dry air. Unlike the occasionally strong and localised cooling induced by the flow of cold air from vents at the base of talus slopes, static cold traps retain their cold air and have little apparent effect on surrounding biota, instead providing potential refugia for organisms that prefer colder temperatures.

In the presence of climate change, the need to make accurate and clearly understandable assessments of carbon sequestration potential, which can be used by the government and industry to plan for technology deployment, has never been greater. We compare three CO (sub 2) storage assessment methodologies: the approach applied by the U.S. Department of Energy in its Carbon Atlas III, the modified U.S. Geological Survey methodology, and the CO (sub 2) Geological Storage Solutions methodology. All three methodologies address storage resources in porous geologic media in sedimentary basins, namely oil and gas reservoirs and saline formations. Based on our analyses, these methodologies are similar in terms of computational formulation. We find that each of the proposed methodologies is science and engineering based. As such, they are important in identifying the geographical distribution of CO (sub 2) storage resource and regional carbon sequestration potential at the national and basin-scale levels for use in energy-related government policy and business decisions. Policy makers need these high-level estimates to evaluate the prospective function that carbon capture and sequestration technologies can play in reducing CO (sub 2) emissions over the long term. The value of these high-level assessments of CO (sub 2) storage resource is to help inform decision makers in governments and industry as to whether carbon capture and sequestration is a climate mitigation option worth pursuing in particular regions.

Baselines studies were also conducted using no catalyst, weak capture agents (CaSiO sub(3)) and strong in situcapture agent for acid gases (CaO). While a similar gas composition can be achieved using CaO rather than alkali hydroxides, the rate of syngas production is greater when using molten alkali hydroxides than when using CaO as the in situcapture agent for acid gases, such as HCl, H sub(2)S and CO sub(2). Parametric studies were conducted to understand the effects of temperature, pressure, catalyst composition, steam flow rate and the ratio of coal to alkali hydroxide on the performance of the molten catalytic gasifier in terms of kinetics and syngas composition. To measure the amount and the rate of coal conversion, we have developed a method for quantifying the coal conversion as the reduction charge remaining, which is related to the chemical oxygen demand remaining in the coal. At temperatures between 800 degree C and 900 degree C, we measured first-order steam-coal gasification rates using sub-bituminous coal of 2 h super(-1) in a fixed bed reactor while capturing significant quantities of both H sub(2)S and CO sub(2), and while also generating 20% methane plus ethane in the syngas on a dry volume basis.

Unlike a point of incidence, the Fresnel zone is complicated by its textural characters that are defined by the dip and azimuth of microreflectors in the zone. The Fresnel-zone texture makes seismic amplitude interpretation more complicated than previously documented. A conceptual model suggests that seismic amplitude variations with offset (AVO), azimuth (AVAz), and frequency (spectral decomposition) were physically related to textural roughness, textural anisotropy, and textural scale of the Fresnel zone, respectively. Textural roughness is defined by the dip deviation of microreflectors and contributes to the AVO intercept and gradient. Textural anisotropy is defined by the degree of the preferred orientation of the microreflectors and directly affects the AVAz signature. Textural scale is defined by the spacing of the microreflectors and controls the selective frequency tuning in spectral decomposition data. The Fresnel-zone texture gives rise to amplitude variations that can not be accurately modeled by using a 1D reflectivity-wavelet convolution algorithm, and thus poses challenges to the reliability of many previous predictions of rock properties and thickness from amplitude. The AVO, AVAz, and spectral decomposition data should be used to characterize Fresnel-zone texture for predicting depositional facies, deformational fabrics, and hydraulic properties in the subsurface.

A comprehensive logging-while-drilling dataset was collected from seven wells at three sites, including two wells at the Walker Ridge 313 site. By constraining the saturations and thicknesses of hydrate-bearing sands using logging-while-drilling data, two-dimensional (2D), cylindrical, r-z and three-dimensional (3D) reservoir models were simulated. The gas hydrate occurrences inferred from seismic analysis are used to delineate the areal extent of the 3D reservoir models. Numerical simulations of gas production from the Walker Ridge reservoirs were conducted using the depressurization method at a constant bottomhole pressure. Results of these simulations indicate that these hydrate deposits are readily produced, owing to high intrinsic reservoir-quality and their proximity to the base of hydrate stability. The elevated in situ reservoir temperatures contribute to high (5-40 MMscf/day) predicted production rates. The production rates obtained from the 2D and 3D models are in close agreement. To evaluate the effect of spatial dimensions, the 2D reservoir domains were simulated at two outer radii. The results showed increased potential for formation of secondary hydrate and appearance of lag time for production rates as reservoir size increases. Similar phenomena were observed in the 3D reservoir models. The results also suggest that interbedded gas hydrate accumulations might be preferable targets for gas production in comparison with massive deposits. Hydrate in such accumulations can be readily dissociated due to heat supply from surrounding hydrate-free zones. Special cases were considered to evaluate the effect of overburden and underburden permeability on production. The obtained data show that production can be significantly degraded in comparison with a case using impermeable boundaries. The main reason for the reduced productivity is water influx from the surrounding strata; a secondary cause is gas escape into the overburden. The results dictate that in order to reliably estimate production potential, permeability of the surroundings has to be included in a model. Abstract Copyright (2012) Elsevier, B.V.

The site descriptions assist in the understanding of the geological development of gas-hydrate-bearing sands and in the assessment of their energy production potential. Three sand-rich units are described from the Walker Ridge site, including multiple ponded sand-bodies representing turbidite channel and associated levee and terminal lobe environments within the Terrebonne basin on the lower slope of the GoM. Older units display fewer but greater-reservoir-quality channel and proximal levee facies as compared to thinner, more continuous, and unconfined sheet-like sands that characterize the younger units, suggesting a decrease in depositional gradient with time in the basin. The three wells in the Green Canyon 955 site penetrated proximal levee sands within a previously recognized Late Pleistocene basin floor turbidite-channel-levee complex. Reservoirs encountered in GC955 exhibit thin-bedded internal structure and complex fault compartmentalization. Two wells drilled in the Alaminos Canyon 21 site tested a large, shallow, sand unit within the Diana mini-basin that exhibits steep lateral margins, non-sinuous elongate form, and flat base with hummocky upper surface. These features suggest deposition as a mass-transport deposit consisting of remobilized sand-rich turbidites or as a large basin-floor fan that was potentially eroded and buried by later-stage, mud-prone, mass-transport deposits.

We focus specifically on sand reservoirs in Hole Alaminos Canyon 21 A (AC21-A), Hole Green Canyon 955 H (GC955-H) and Hole Walker Ridge 313 H (WR313-H). Using a new logging-while-drilling directional resistivity tool and a one-dimensional inversion developed by Schlumberger, we resolve the resistivity of the current flowing parallel to the bedding, R (sub prallel) and the resistivity of the current flowing perpendicular to the bedding, R (sub perpendicular) . We find the sand reservoir in Hole AC21-A to be relatively isotropic, with R (sub parallel) and R (sub perpendicular) values close to 2Omega m. In contrast, the gas hydrate-bearing sand reservoirs in Holes GC955-H and WR313-H are highly anisotropic. In these reservoirs, R (sub parallel) is between 2 and 30Omega m, and R (sub perpendicular) is generally an order of magnitude higher. Using Schlumberger's WebMI models, we were able to replicate multiple resistivity measurements and determine the formation resistivity the gas hydrate-bearing sand reservoir in Hole WR313-H. The results showed that gas hydrate saturations within a single reservoir unit are highly variable. For example, the sand units in Hole WR313-H contain thin layers (on the order of 10-100 cm) with varying gas hydrate saturations between 15 and 95%. Our combined modeling results clearly indicate that the gas hydrate-bearing sand reservoirs in Holes GC955-H and WR313-H are highly anisotropic due to varying saturations of gas hydrate forming in thin layers within larger sand units.

Throughout the 1980s and 1990s, work focused on massive gas hydrates deposits that were found to form at and near the seafloor in association with hydrocarbon seeps. However, as global scientific and industrial interest in assessment of the drilling hazards and resource implications of gas hydrate accelerated, focus shifted to understanding the nature and abundance of "buried" gas hydrates. Through 2005, despite the drilling of more than 1200 oil and gas industry wells through the gas hydrate stability zone, published evidence of significant sub-seafloor gas hydrate in the GoM was lacking. A 2005 drilling program by the GoM Gas Hydrate Joint Industry Project (the JIP) provided an initial confirmation of the occurrence of gas hydrates below the GoM seafloor. In 2006, release of data from a 2003 industry well in Alaminos Canyon 818 provided initial documentation of gas hydrate occurrence at high concentrations in sand reservoirs in the GoM. From 2006 to 2008, the JIP facilitated the integration of geophysical and geological data to identify sites prospective for gas hydrate-bearing sands, culminating in the recommendation of numerous drilling targets within four sites spanning a range of typical deepwater settings. Concurrent with, but independent of, the JIP prospecting effort, the Bureau of Ocean Energy Management (BOEM) conducted a preliminary assessment of the GoM gas hydrate petroleum system, resulting in an estimate of 607 trillion cubic meters (21,444 trillion cubic feet) gas-in-place of which roughly one-third occurs at expected high concentrations in sand reservoirs. In 2009, the JIP drilled seven wells at three sites, discovering gas hydrate at high saturation in sand reservoirs in four wells and suspected gas hydrate at low to moderate saturations in two other wells. These results provide an initial confirmation of the complex nature and occurrence of gas hydrate-bearing sands in the GoM, the efficacy of the integrated geological/geophysical prospecting approach used to identify the JIP drilling sites, and the relevance of the 2008 BOEM assessment.

Primary seafloor hazards include infrastructure, hardgrounds, chemosynthetic communities, and areas of high slope or potential seafloor instability. Shallow subsurface hazards include strata that may contain overpressured water, free gas, or gas hydrate. Among these issues, the potential hazards posed by gas hydrate have historically been the most difficult to quantify and constrain. This paper reviews the history of gas hydrate shallow hazard assessment, much of which has been framed by difficulties in remote detection and quantification of typical low-saturation, mud-hosted hydrate occurrences. Recent drilling results indicate that such accumulations can be safely drilled using existing industry protocols. However, assessment of drilling hazards associated with high saturation, sand-hosted hydrates warrant further investigation, and therefore was a key focus of the Gulf of Mexico Gas Hydrate Joint Industry Project Leg II (JIP Leg II) program conducted in 2009. Pre-drill site hazard assessment for JIP Leg II utilized standard industry methods in which geohazards associated with gas hydrate and free gas were identified in a primarily-qualitative manner using seismic amplitude analysis, seismic stratigraphic interpretation, and geo-pressure analysis. While these methods can reliably detect shallow hydrocarbons, including highly-concentrated gas hydrates, they are not sufficient to determine if free gas may exist below gas hydrate, particularly where they occur in close vertical succession. Such undetected free gas occurrences can pose potential drilling hazards that can be quantitatively assessed using advanced seismic methods. Abstract Copyright (2012) Elsevier, B.V.

The three-dimensional nanofiber network cathode has several advantages: (i) high porosity; (ii) high percolation; (iii) continuous pathway for charge transport; (iv) good thermal stability at the operating temperature; and (v) excellent scaffold for infiltration. The fuel cell with the monolithic LSCF nanofiber cathode exhibits a power density of 0.90 W cm super(-2) at 1.9 A cm super(-2) at 750 degree C. The electrochemical performance of the fuel cell has been further improved by infiltration of 20 wt% of gadolinia-doped ceria (GDC) into the LSCF nanofiber cathode. The fuel cell with the LSCF-20% GDC composite cathode shows a power density of 1.07 W cm super(-2) at 1.9 A cm super(-2) at 750 degree C. The results obtained show that one-dimensional nanostructures such as nanofibers hold great promise as electrode materials for intermediate-temperature SOFCs.

Each hydrofracture requires millions of gallons of water amended with various chemicals to maximize gas extraction. Flowback water from the wells is typically high in salts dissolved from the formation and much of it is stored in surface ponds for further treatment and recycling. The storage of water can result in stagnant conditions and the generation of noxious odors, so aeration units are occasionally used to circulate and aerate the water. In this study, we examined the physical and biogeochemical changes in a produced water storage pond in Greene County, PA after 9 days of aeration. Physical parameters (including temperature, conductivity, pH, oxidation-reduction potential (ORP), and dissolved oxygen (DO)) were measured and water samples collected from selected depths along defined transects by boat. In the laboratory, element concentrations were measured by ICP-OES, anions by ion chromatography, dissolved sulfide by iodometric titration, and dissolved iron by phenanthroline complexation. Bacteria were examined using direct staining and fluorescent in situ hybridization (FISH) methods. All parameters measured were consistent with the existence of initially stratified conditions in the pond, with fresher water on the immediate surface, underlain by highly saline anoxic waters. Aeration resulted in the complete mixing of the water column and changes in the concentration of redox-sensitive chemical species. Water chemistry was dominated by Na (367 mM), Ca (119 mM) and Cl (508 mM) with smaller contributions from Mg (29 mM) and SO (sub 4) (23.1 mM). Dissolved sulfide concentrations prior to aeration were very high (ca. 1 mM), but were negligible following aeration. Bacterial analyses suggested a shift from a population dominated by sulfate-reducing bacteria at depth to a more diverse one throughout the water column following aeration. The aeration method employed was therefore effective at disrupting the stratification of the water column and the reduction of the sources and causative agents of noxious dissolved sulfide odor from the pond.

The community of Greenwood Furnace flourished here from 1834 to 1904 as a busy industrial complex based on iron production. The charcoal hearths and associated wagon roads are viewable in shaded relief images of the LiDAR digital elevation model (DEM) as circular features resembling small craters. Strings of hearths are readily evident along similar topographic contour lines on the adjacent hillsides. Approximately 500 historic charcoal hearths were identified in a 40 square mile area surrounding Greenwood Furnace. Today, the area around Greenwood Furnace supports a mixed hardwood forest and the charcoal hearths easily go unnoticed when hiking through these woods.

Such deposits in eastern North America are especially well-known in the karst region of western Virginia, often associated with the discharge of thermal spring waters, but reports of tufa formations outside of this specific region are few. Recently, we have studied a perched springline tufa that is associated with the Benwood Limestone member of the Upper Pennsylvanian, Monongahela Group. Like many sites in this region, the steep elevational drop in discharged water and enhanced carbon dioxide release are related to human disturbances of natural terrain during the past 150 years, such as highway and railroad construction and the strip mining of bituminous coal. Preliminary core material was collected from the tufa site and analyzed by computed tomography (CT) scanning. The core scans showed the limestone material to be extremely vuggy and porous. The CT scanning produced 3D volume reconstructions with resolution in the 20-30 micron range making it possible to nondestructively extract various physical characteristics of the tufa samples. For each sample the porosity and pore size distribution were extracted as well as the surface area of the porosity and the connectivity of the functional pore spaces. The observed limestone structure is consistent with the active and continuous calcification of the moss that grows in dense mats on the surface of the tufa deposit. Such core scans may provide the basis for future descriptive modeling in the fields of karst geology and carbon dioxide sequestration.

One alloy, Haynes 282, has shown robust capability in terms of starting microstructure (gamma prime size & volume fraction). Another alloy, Nimonic 105, has exhibited the potential for improved creep behavior in the peak aged condition as well as when aged. These alloys are among several that offer the best potential for building steam turbine components for a power plant operating at =1400 degree F. Design strategy, strengthening concepts and creep behavior will be discussed for each alloy, highlighting differences in each alloy and their respective strengths relative to use as steam turbine components. Suggestions for improving alloy performance will also be discussed.

Gas separation membranes can be utilized to achieve this goal. Although a variety of hydrogen separation membrane materials exist today, none of them is shown to be suitable to be employed in contaminant laden syngas at elevated temperatures. Cu-Pd alloys with ordered bcc (B2) phase have demonstrated some promise for being resistant against surface poisoning and corrosion. In these alloys, the superior hydrogen flux increases up to temperatures at which the alloy transforms primarily into fcc structure where a sharp drop in flux occurs. First principles DFT calculations and experiments (XRD, SEM, TEM) have shown that magnesium additions to the Cu-Pd alloy extend the stability of the B2 phase field, potentially improving the hydrogen permeability at higher temperatures.

While renewable energy resources will continue to grow in importance, environmentally responsible fossil energy production will be necessary to provide a bridge to the next energy revolution. This drive to increase process efficiencies and reduce the environmental impact in fossil-based energy production will require processes with increased operating temperatures and pressures, and increasingly aggressive operating environments. The practical result is a requirement for affordable and reliable high-performance materials and materials systems to enable these next-generation fossil energy systems. This talk will focus on the research being performed within the National Energy Technology Laboratory's Office of Research & Development to meet this requirement for high performance yet affordable materials.

Due to the complexity of a typical multi-oxidant environment, it is very challenging if not impossible to predict the corrosion product with confidence. The computational approach available is largely based on thermodynamic calculations without any consideration of kinetics effect. To address the kinetic effect, a multi-faceted modeling approach is being developed at NETL/DOE to study oxidation kinetics under different length scales. Some progresses are discussed in this presentation based on results from mean-field and phase-field methods. The computational tools can be used to simulate environmental effect on oxidation behavior.

AN - 923191141; 22280145 AB - Controlled self-assembly of zero-dimensional gold nanoparticles and construction of complex gold nanostructures from these building blocks could significantly extend their applications in many fields. Carbon nanotubes are one of the most promising inorganic templates for this strategy because of their unique physical, chemical, and mechanical properties, which translate into numerous potential applications. Here we report the bottom-up synthesis of gold nanowires in aqueous solution through self-assembly of gold nanoparticles on single-walled carbon nanotubes followed by thermal-heating-induced nanowelding. We investigate the mechanism of this process by exploring different graphitic templates. The experimental work is assisted by computational studies that provide additional insight into the self-assembly and nanowelding mechanism. We also demonstrate the chemical sensitivity of the nanomaterial to parts-per-billion concentrations of hydrogen sulfide with potential applications in industrial safety and personal healthcare.

During the development of a Pd/ gamma -Al sub(2)O sub(3) sorbent for warm (200 degree C) fuel gas cleanup, the catalytic formation of carbonyl sulfide (COS), was observed. This is attributed to a heterogeneous reaction involving fuel gas components (CO/CO sub(2)/H sub(2)/H sub(2)S/H sub(2)O) and Pd/ gamma -Al sub(2)O sub(3). The concentration of COS increases 200-fold when exposed to the Pd/ gamma -Al sub(2)O sub(3) sorbent. A Langmuir-Hinshelwood reaction mechanism is proposed and a kinetic model is developed based on experimental results. The effect of gamma -Al sub(2)O sub(3), a common catalyst for hydrolysis of COS, and H sub(2)O on the COS concentration is discussed.

A controlled release of CO2 with an added perfluorocarbon tracer was conducted in July 2009 in a multi-laboratory study of atmospheric transport and detection technologies. Tracer plume dispersion was measured with various meteorological conditions using a tethered balloon system with Multi-Tube Remote Samplers (MTRS) at elevations of 10m, 20m, and 40m above ground level (AGL), as well as a ground-based portable tower with monitors containing sorbent material to collect the tracer at 1m, 2m, 3m, and 4m AGL. Researchers designed a horizontal grid of sampling locations centered at the tracer plume source, with the tower positioned at 10m and 30m in both upwind and downwind directions, and the MTRS spaced at 50m and 90m downwind and 90m upwind. Tracer was consistently detected at elevated concentrations at downwind sampling locations. With very few exceptions, higher tracer concentrations correlated with lower elevations. Researchers observed no statistical difference between sampling at 50m and 90m downwind at the same elevation. The US EPA AERMOD model applied using site-specific information predicted transport and dispersion of the tracer. Model results are compared to experimental data from the 2009 ZERT experiment. Successful characterization of the tracer plume simulated by the ZERT experiment is considered a step toward demonstrating the feasibility of remote sampling with unmanned aerial systems (UAS's) at future sequestration sites.

Class C fly ash tended to release the highest quantity of minor and trace elements-including alkaline earth elements, sodium, chromium, copper, manganese, lead, titanium, and zinc-during sequential extraction, with bottom ash yielding the lowest. Strontium isotope ratios ( (super 87) Sr/ (super 86) Sr) in bulk-CUB samples (total dissolution of CUB) are generally higher in class F ash than in class C ash. Bulk-CUB ratios appear to be controlled by the geologic source of the mineral matter in the feed coal, and by Sr added during desulfurization treatments. Leachates of the CUB generally have Sr isotope ratios that are different than the bulk value, demonstrating that Sr was not isotopically homogenized during combustion. Variations in the Sr isotopic composition of CUB leachates were correlated with mobility of several major and trace elements; the data suggest that arsenic and lead are held in phases that contain the more radiogenic (high- (super 87) Sr/ (super 86) Sr) component. A changing Sr isotope ratio of CUB-interacting waters in a disposal environment could forecast the release of certain strongly bound elements of environmental concern. This study lays the groundwork for the application of Sr isotopes as an environmental tracer for CUB-water interaction.

The activation energy was deduced from the particle cohesive energy and the ignition temperature was calculated using the condition that the heat generated by the combustion reactions is sufficient to counterbalance the particle heat loss to the surrounding. Heat loss was assumed to be in the transient regime and the combustion heat generation was calculated using the simplest Arrhenius-type model. Using aluminum as an example, the results showed that for particles of sizes larger than 50 nm, increasing the particle size had a little effect on the number of the surface atoms, the activation energy and the ignition temperature. As the particle size decreases the number of the surface atoms increases and the corresponding activation energy, E sub(d)/E sub( infinity ) and the ignition temperature decrease.

In this study, we use controlled experiments and computed tomography (CT) imaging to investigate the preferential mode of gas migration in three-dimensional samples of water-saturated silica-sand, silica-silt, kaolin-clay, as well as multi-layered sediments. Our experimental system allows independent control of radial and axial confining stresses and pore pressure while performing continuous x-ray CT scanning. The CT image analysis of the gas migration provides the first experimental confirmation, in three-dimensional systems, that capillary invasion preferentially occurs in coarse-grained sediments whereas grain displacement and conduit openings are dominant in fine-grained sediments [1]. Our findings rationalize prior field observations and pore-scale modeling results which suggest the strong control of grain size and sediment mechanics on the nature of gas invasion into water-filled porous media. These data provide critical experimental evidence to explain the means by which conduits for the transit of methane gas may be established through the gas hydrate stability zone in oceanic sediments, and cause large episodic releases of carbon into the deep ocean.

These lakes form in permafrost regions and grow as the water amplifies subsurface heating and causes further degradation of the permafrost. Areas of thawed ground (thaw-bulbs, or taliks) can develop beneath them. When a talik intersects fractures or permeable zones linked to free-gas accumulations, coal beds, or permafrost-associated gas hydrate, methane can be released from the lake. In 2009, a four-core transect extending from an active gas seep in Qalluuraq Lake (Lake Q), an Alaskan thermokarst lake, was taken for lithological analysis to complement paleoecological and biogeochemical studies investigating the current and historical flux of methane from this lake. As part of this study, we completed sedimentological analyses to constrain the lithology of the system and evaluate potential near-lake floor geologic controls on methane seepage at this site. Visual descriptions were completed for each core. Grain size, x-ray diffraction (XRD), petrographic, elemental (C and N) and accelerator mass spectrometer (AMS) radiocarbon analyses were also conducted on subsamples from the cores. The major lithology of all four cores is a quartz-rich, chert-bearing, medium-grained sand. Organic material, including grasses, seed pods, and reworked coal fragments, was observed in some intervals as laminae or as dispersed material. XRD and petrographic analyses indicate quartz is the dominant mineral in every core, though some of the AMS dates on organic laminae in the cores fit with paleoecological reconstructions from the site relating to wetland succession. Though the modern Lake Q is a lacustrine environment, likely formed via thermokarst processes, its underlying sediment is fluvially reworked marine sand. Our analyses indicate that these sediments are part of the Gubik Formation, a Quaternary age sedimentary formation blanketing much of the ANS and representing a variety of depositional environments, including nearshore marine, fluvial, lacustrine, eolian, thermokarst, and glacial. Methane ebullition, resulting from wetlands initiation approximately 12,000 cal yr BP, appears to have winnowed fine-grained organic material from the active seep sediments. The resulting coarse-grained and moderately well-sorted seep sediments are an unrestricted conduit that facilitates the gas and fluid flux to the lake and atmosphere.

Direct observations of CO (sub 2) flowing through shallow drinking water aquifers are invaluable for informing credible risk assessments. To this end, we have sampled shallow wells in a natural analog site in New Mexico, USA, where CO (sub 2) from natural sources is upwelling from depth, and have conducted laboratory experiments on aquifer sediments. Collectively, this work has generated insights into the processes controlling major ion and trace element geochemistry in a CO (sub 2) -rich system. One finding has been that impacts related to upwelling saline water far exceed those related to in-situ CO (sub 2) -induced trace metal mobilization. We have also developed 3-D reactive-transport simulations to represent the key aspects of this particular type of drinking water aquifer. In this paper we will summarize field and laboratory findings, and compare reactive-transport simulations with field data. We will then show how field-tested simulations can be used to predict the temporal evolution of shallow groundwater in hypothetical CO (sub 2) leakage scenarios. These simulations highlight the importance of transient, non-equilibrium effects. These effects should be carefully considered in risk assessments and monitoring network design. We conclude by presenting sensitivity analysis results showing the most important uncertain model parameters; these results can be used to guide future laboratory and field studies.

Estimating carbon dioxide solubility (TPX) in brine under carbon sequestration conditions with high temperature, pressure and salinity is crucial in choosing suitable carbon sequestration reservoirs and determining the carbon dioxide storage capacity of each. Multiple mathematical models are available for predicting the solubility of CO (sub 2) in brine. Although comparisons of each model with a particular experimental data set collected under certain TPX conditions have been published by the model developers, few studies have been done to compare these models using a comprehensive experimental data set and rigorous statistical methods. In this study, available CO (sub 2) solubility experimental data and nine mathematical models for the prediction of CO (sub 2) solubility in brine were collected. Five of these predictive models are empirical or semi-empirical and the remainders are based on different equations of state. Statistical criteria, such as the AIC and BIC were employed to determine the goodness of fit of each mathematical model with the CO (sub 2) solubility experimental data set. Results of this analysis determine the best mathematical predictive model for the calculation of carbon dioxide solubility under carbon sequestration conditions. Preliminary analysis shows that simplified models with fewer variables perform equally well with those having more. The study also presents a quantitative approach to determine the best CO (sub 2) solubility predictive model through use of a regression tree.

NRAP is conducting risk and uncertainty analysis in the areas of reservoir performance, natural leakage pathways, wellbore integrity, groundwater protection, monitoring, and systems level modeling. The mission of NRAP is "to provide the scientific underpinning for risk assessment with respect to the long-term storage of CO (sub 2) , including assessment of residual risk associated with a site post-closure". Additionally, NRAP will develop a strategic, risk-based monitoring protocol, such that monitoring at all stages of a project effectively minimizes uncertainty in the predicted behavior of the site, thereby increasing confidence in storage integrity. NRAP's research focus in the area of groundwater protection is divided into three main tasks: 1) development of quantitative risk profiles for potential groundwater impacts; 2) filling key science gaps in developing those risk profiles; and 3) field-based confirmation. Within these three tasks, researchers are engaged in collaborative studies to determine metrics to identify system perturbation and their associated risk factors. Reservoir simulations are being performed to understand/predict consequences of hypothetical leakage scenarios, from which reduced order models are being developed to feed risk profile development.

Fractures in these caprocks, whether preexisting or newly created due to CO (sub 2) injection, may serve as leakage pathways for the injected CO (sub 2) . The hydrodynamic properties of these fractures, e.g. permeability and relative permeability, are primarily controlled by fracture geometries, aperture and roughness, which are subject to alteration caused by reactions between CO (sub 2) -acidified brine and minerals along the fracture faces. In this study, computational fluid dynamics simulations were performed on fracture geometries representing the initial and final conditions of an experiment in which a fractured carbonate caprock sample was exposed to CO (sub 2) -acidified brine flow. This experiment exhibited a net decrease in average fracture aperture. X-ray computed micro-tomography scans taken before and after the experiment were thresholded and used to reconstruct the fracture geometries. The generated meshes were refined and used in OpenFOAM for single-phase flow simulations to estimate intrinsic permeabilities. The simulation results carry important implications regarding the impact of geochemical reactions along the fracture pathway on hydrodynamic properties. Results from this study will provide important insights for leakage risk assessment of CO (sub 2) storage sites with potentially fractured caprocks.

a three-way analysis of the impacts to shallow groundwater composition and storage AN - 1400616457; 2013-052975 AB - Since 1987, coalbed methane (CBM) production in the Wyoming portion of the Powder River basin has generated 1.2 X 10 (super 11) m (super 3) (4,240 bcf) of natural gas and 1.0 X 10 (super 9) m (super 3) (35.3 bcf) of co-produced water. Year-round introduction of the produced waters with potentially soil-damaging Na-rich composition into infiltration impoundments and ephemeral hydrologic systems have led to serious concerns related to the handling of the water. An alluvial aquifer site where treated Na-HCO (sub 3) - to Na-SO (sub 4) -type CBM water is added into the unsaturated zone ( approximately 0.9m depth) through the use of a subsurface drip irrigation (SDI) system has been studied to assess the impact to groundwater levels and composition. The SDI system is designed to provide water for alfalfa, which has roots that can reach the depth of the SDI emitters, whereas the Na-rich solutes are stored below the more Na-sensitive upper layers of the soil column. In the first two years of SDI operation, little net change in groundwater levels in wells outside of the SDI areas was observed, whereas groundwater levels have increased in some SDI areas of the site by more than 0.6 m. Changes in groundwater specific conductance, an indicator of solute load, have varied substantially, with both increasing and decreasing trends observed within SDI and non-SDI wells. To better understand the nature of these changes, concentration data (Ba, Cl, Fe, HCO (sub 3) , H (sub 2) O, Mg, Na, Si, SO (sub 4) , and Sr) for water samples collected from 14 monitoring wells during eight rounds of quarterly groundwater sampling were arranged in a three-way array (wells x constituents x sampling events). Because the focus of this study is the chemical composition of groundwater samples, analyses focused on the molar proportions of the chemical constituents, rather than the raw molar concentration data. In attempt to find underlying multivariate structure and to identify processes controlling the data, the three-way array was examined using the recently developed Tucker models for compositional data. Results from this investigation show the potential controls and impacts of SDI application of CBM waters on a shallow groundwater system.

In order to assess the effect of Marcellus Shale development on water quality, there is a need to develop tools that can be used to track the source and fate of these highly saline waters co-produced as a result of shale gas extraction. In the area of Marcellus Shale development, the co-produced water can have similar chemical constituents found in saline formations and/or coal mines originating from several thousand acres of abandoned coal mines or deep coal mines in this region. Hence, it can be difficult to decouple the contribution of co-produced water from coal mine waters and/or saline formation waters to the surface waters and aquifers based on the general geochemical characteristics alone. We tested the applicability of a multiple stable isotope approach to distinguish different water sources in an area of accelerating shale gas development. Water samples were collected from fresh surface waters, coal mine discharges and co-produced water from a Marcellus well in Pennsylvania. Preliminary data shows that O and H isotopic composition of water (delta (super 18) O (sub H2O) and delta D (sub H2O) ), C isotope composition dissolved inorganic carbon (delta (super 13) C (sub DIC) ), and S and O isotope composition of dissolved sulfate (delta (super 34) S (sub SO4) and delta (super 18) O (sub SO4) ) of different end-members are very distinct. The isotopic variations most likely originate due to the variations in water-rock interactions, recharge sources, recharge pathways, and age of the waters. These distinctions may be used to fingerprint different water sources in this area.

The goal of the Eastern Gas Shales Project (EGSP) was to assess the technical challenges of recovering natural gas from extensive, organic-rich, Devonian-age shales in the Eastern United States. This program became the responsibility of the U.S. Department of Energy when it was created in August 1977. The major components of the EGSP were resource characterization and inventory, the development of extraction technology, and transfer of that technology to industry. From 1976 to 1982, the EGSP used cooperative agreements with drillers to collect and characterize oriented core from 38 wells targeting a variety of Devonian shales in the Appalachian, Michigan and Illinois Basins. Marcellus Shale core from an EGSP well drilled in 1978 in Morgantown, WV was analyzed by the Institute of Gas Technology in 1986. Results suggested that this shale was capable of containing much more gas than had been previously estimated, and that the resource might be quite large. Shale gas development awaited improved production techniques. Mitchell Energy had been experimenting on the Barnett Shale in the Fort Worth Basin since the early 1980s, finally beginning successful shale gas production in 1997 from horizontal wells that used directional drilling technology and staged hydraulic fracturing. The Fayetteville and Haynesville Shales in Arkansas were recognized as sharing many of the same gas productive characteristics as the Barnett Shale, leading to the subsequent development of these formations. Range Resources drilled the Renz #1 well in Washington Co, PA in 2004 to test Ordovician prospects. The target unit had poor gas shows, but evidence of gas in the overlying Marcellus led Range to review DOE reports on shale gas, and then hydraulically fracture the Marcellus in Renz #1. After getting an initial production of 300,000 cubic feet per day, Range drilled and stimulated the first horizontal well in the shale in 2005. Gulla #9 had an initial production of 4 million cubic feet per day. Other Marcellus wells soon followed, developing the play remarkably within five years.

In this paper, a method is developed for determining temperature-dependent critical values of soil CO (sub 2) flux for preliminary leak detection inference. The method is illustrated using surface CO (sub 2) flux measurements obtained from the AmeriFlux network fit with alternative models for the soil CO (sub 2) flux versus soil temperature relationship. The models are fit first to determine pooled parameter estimates across the sites, then using a Bayesian hierarchical method to obtain both global and site-specific parameter estimates. Model comparisons are made using the deviance information criterion (DIC), which considers both goodness of fit and model complexity. The hierarchical models consistently outperform the corresponding pooled models, demonstrating the need for site-specific data and estimates when determining relationships for background soil respiration. A hierarchical model that relates the square root of the CO (sub 2) flux to a quadratic function of soil temperature is found to provide the best fit for the AmeriFlux sites among the models tested. This model also yields effective prediction intervals, consistent with the upper envelope of the flux data across the modeled sites and temperature ranges. Calculation of upper prediction intervals using the proposed method can provide a basis for setting critical values in CO (sub 2) leak detection monitoring at sequestration sites.

The system had to be able to reach a depth of approximately 2,000', core the entire interval, leave a 12-1/4" borehole suitable for hydrologic testing, and introduce no contaminants, such as drilling mud, into the environment. Air was also considered a contaminant since its water content was different than that in the in situ hydrologic system. To achieve this "first of a kind" level of minimum drilling impact, a dual-wall drilling system was utilized that allowed high pressure air injection and a vacuum return up the center of the drill-pipe to pull cuttings and air to the surface. Another mitigation feature included cooling of the compressed air for coring and sending it through a separator in order to ensure the core did not become saturated from condensed water. The manufacturer, Lang Exploratory Drilling, built and commercialized a rig similar to the LM-300 for rapidly drilling dewatering holes for the mining industry. With the advent of the "Unconventional Era" in oil and gas, exploration success is now all about site characterization. Further commercialization efforts have been successful using the same "purpose built" approach to rig design as the LM-300. DOE's National Energy Technology Laboratory (NETL) funded the first demonstration of hybrid coiled tubing drilling systems in the lower 48 U.S. The result of that demonstration was the commercialization of over 1 Tcf of shallow tight gas in the Niobrara Formation of western Kansas and eastern Colorado. Coiled tubing drilling is now rapidly penetrating gas shale markets in the U.S.. The use of small "purpose built" coiled tubing drilling rigs also continues to be a key enabler to the future of high resolution seismic, permanently installed state-of-art geophones for micro-seismic monitoring and active seismic using "downward looking VSP" technology also demonstrated by NETL.

The instrument response to liquid phase standards is analyzed to produce empirical factors relating ion generation and transmission efficiencies to standard operating parameters. Empirical factors generated for liquid phase samples are then used to produce semi-quantitative analysis of both mixed liquid/gas samples and pure gas samples. The method developed is similar to the semi-quantitative analysis algorithms in the commercial software, which have here been expanded to include gas phase elements such as Xe and Kr. Equations for prediction of relative ionization efficiencies and isotopic transmission are developed for several combinations of plasma operating conditions, which allows adjustment of limited parameters between liquid and gas injection modes. In particular, the plasma temperature and electron density are calculated from comparison of experimental results to the predictions of the Saha equation. Comparisons between operating configurations are made to determine the robustness of the analysis to plasma conditions and instrument operating parameters. Using the methods described in this research, the elemental concentrations in a liquid standard containing 45 analytes and treated as an unknown sample were quantified accurately to +/-50% for most elements using 133Cs as a single internal reference. The method is used to predict liquid phase mercury within 12% of the actual concentration and gas phase mercury within 28% of the actual concentration. The results verify that the calibration method facilitates accurate semi-quantitative, gas phase analysis of metal species with sufficient sensitivity to quantify metal concentrations lower than 1ppb for many metallic analytes.

[Part 3 of 22] T2 - TEXAS CLEAN ENERGY PROJECT, ODESSA, ECTOR COUNTY, TEXAS. AN - 888700702; 15006-6_0003 AB - PURPOSE: The provision of $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) 15 miles southwest of the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Summit Texas Clean Energy, LLC (Summit) would build the poly-generation (polygen) plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 along a Union Pacific Railroad line. The plant would be designed and constructed to capture approximately 90 percent of its CO2. During the demonstration phase of operations, the project would sequester 2.5 to 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and linear facilities, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This final EIS evaluates the proposed project, operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. The Department of Energy's preferred alternative is to provide financial assistance for Summit's proposed project. The assistance would amount to approximately 26 percent of the project's total capital cost of at least $1.73 billion (2009 dollars) and would be provided on a costshare basis. POSITIVE IMPACTS: The TCEP would generate up to 1.7 billion net kilowatt-hours of electricity per year for delivery to the electric grid while also benefiting the recovery of oil and gas in portions of the Permian Basin. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. NEGATIVE IMPACTS: Construction would result in the permanent loss of up to 600 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen dioxide at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced and non-captured CO2 emissions from operations would be approximately 300,000 tons per year. Ground water quality impacts could result from the limited potential for upward migration of CO2 or displacement of native fluids. High-intensity lighting would have adverse impacts on night sky viewing conditions.

[Part 4 of 22] T2 - TEXAS CLEAN ENERGY PROJECT, ODESSA, ECTOR COUNTY, TEXAS. AN - 888700549; 15006-6_0004 AB - PURPOSE: The provision of $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) 15 miles southwest of the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Summit Texas Clean Energy, LLC (Summit) would build the poly-generation (polygen) plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 along a Union Pacific Railroad line. The plant would be designed and constructed to capture approximately 90 percent of its CO2. During the demonstration phase of operations, the project would sequester 2.5 to 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and linear facilities, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This final EIS evaluates the proposed project, operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. The Department of Energy's preferred alternative is to provide financial assistance for Summit's proposed project. The assistance would amount to approximately 26 percent of the project's total capital cost of at least $1.73 billion (2009 dollars) and would be provided on a costshare basis. POSITIVE IMPACTS: The TCEP would generate up to 1.7 billion net kilowatt-hours of electricity per year for delivery to the electric grid while also benefiting the recovery of oil and gas in portions of the Permian Basin. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. NEGATIVE IMPACTS: Construction would result in the permanent loss of up to 600 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen dioxide at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced and non-captured CO2 emissions from operations would be approximately 300,000 tons per year. Ground water quality impacts could result from the limited potential for upward migration of CO2 or displacement of native fluids. High-intensity lighting would have adverse impacts on night sky viewing conditions.

This final EIS evaluates the proposed project, operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. The Department of Energy's preferred alternative is to provide financial assistance for Summit's proposed project. The assistance would amount to approximately 26 percent of the project's total capital cost of at least $1.73 billion (2009 dollars) and would be provided on a costshare basis. POSITIVE IMPACTS: The TCEP would generate up to 1.7 billion net kilowatt-hours of electricity per year for delivery to the electric grid while also benefiting the recovery of oil and gas in portions of the Permian Basin. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. NEGATIVE IMPACTS: Construction would result in the permanent loss of up to 600 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen dioxide at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced and non-captured CO2 emissions from operations would be approximately 300,000 tons per year. Ground water quality impacts could result from the limited potential for upward migration of CO2 or displacement of native fluids. High-intensity lighting would have adverse impacts on night sky viewing conditions.

The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Summit Texas Clean Energy, LLC (Summit) would build the poly-generation (polygen) plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 along a Union Pacific Railroad line. The plant would be designed and constructed to capture approximately 90 percent of its CO2. During the demonstration phase of operations, the project would sequester 2.5 to 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2.

[Part 14 of 22] T2 - TEXAS CLEAN ENERGY PROJECT, ODESSA, ECTOR COUNTY, TEXAS. AN - 888696136; 15006-6_0014 AB - PURPOSE: The provision of $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) 15 miles southwest of the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Summit Texas Clean Energy, LLC (Summit) would build the poly-generation (polygen) plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 along a Union Pacific Railroad line. The plant would be designed and constructed to capture approximately 90 percent of its CO2. During the demonstration phase of operations, the project would sequester 2.5 to 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and linear facilities, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This final EIS evaluates the proposed project, operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. The Department of Energy's preferred alternative is to provide financial assistance for Summit's proposed project. The assistance would amount to approximately 26 percent of the project's total capital cost of at least $1.73 billion (2009 dollars) and would be provided on a costshare basis. POSITIVE IMPACTS: The TCEP would generate up to 1.7 billion net kilowatt-hours of electricity per year for delivery to the electric grid while also benefiting the recovery of oil and gas in portions of the Permian Basin. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. NEGATIVE IMPACTS: Construction would result in the permanent loss of up to 600 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen dioxide at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced and non-captured CO2 emissions from operations would be approximately 300,000 tons per year. Ground water quality impacts could result from the limited potential for upward migration of CO2 or displacement of native fluids. High-intensity lighting would have adverse impacts on night sky viewing conditions.

The TCEP would consist of the polygen plant and linear facilities, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This final EIS evaluates the proposed project, operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. The Department of Energy's preferred alternative is to provide financial assistance for Summit's proposed project. The assistance would amount to approximately 26 percent of the project's total capital cost of at least $1.73 billion (2009 dollars) and would be provided on a costshare basis. POSITIVE IMPACTS: The TCEP would generate up to 1.7 billion net kilowatt-hours of electricity per year for delivery to the electric grid while also benefiting the recovery of oil and gas in portions of the Permian Basin. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. NEGATIVE IMPACTS: Construction would result in the permanent loss of up to 600 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen dioxide at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced and non-captured CO2 emissions from operations would be approximately 300,000 tons per year. Ground water quality impacts could result from the limited potential for upward migration of CO2 or displacement of native fluids. High-intensity lighting would have adverse impacts on night sky viewing conditions.

This challenge is enormous. For comparison, replacing one-third of the world's total energy demand with a CO sub(2)-free alternative would require the construction of approximately 2,500 new 1-GW nuclear power plants -- roughly one per week for 50 years -- or one hydroelectric plant the size of China's Three Gorges Dam every four months over the same period (1). To compound the difficulty of this challenge, the world's demand for energy is expected to more than double by 2050.

The uncoated alloy showed a considerable amount of spallation and buckling whereas the Pt-NiAl coated alloy remained protective throughout hundred 1 h-cycles. The interfacial failure is mainly ascribed to the increased thermal strain by the encapsulation of external SiO sub(2) particulates in an outward-growing Cr sub(2)O sub(3) layer. However, the particles were not embedded in the thermally grown oxide of the Pt-NiAl coated alloy due to the slow inward-growing characteristics of Al sub(2)O sub(3) scales. The buckling of the Cr sub(2)O sub(3) scale with embedded SiO sub(2) was analyzed with (1) a classical buckling criterion using the instantaneous coefficients of thermal expansion of the constituents, and (2) finite element analyses (FEA) to estimate the local interfacial shear stresses. It turns out that the thermal strain with embedded SiO sub(2) is larger than the experimentally determined critical thermal strain ( epsilon sub(b)) explaining the buckling of the oxide scale observed in the experiment. The FEA results demonstrate that local shear stresses at the metal/oxide interface are significantly amplified near the SiO sub(2) particles showing that the buckling of oxide can be readily initiated especially in the vicinity of the embedded particles.

A thermodynamic analysis of a solid oxide fuel cell with a liquid metal anode is developed. Pertinent thermochemical and thermophysical properties of liquid tin in particular are detailed. An experimental setup for analysis of LTA-SOFC anode kinetics is described, and data for a planar cell under hydrogen indicated an effective oxygen diffusion coefficient of 5.3 x 10[super]-5 cm[super]2 s[super]-1 at 800 [deg]C and 8.9 x 10[super]-5 cm[super]2 s[super]-1 at 900 [deg]C. This value is similar to previously reported literature values for liquid tin. The oxygen conductivity through the tin, calculated from measured diffusion coefficients and theoretical oxygen solubility limits, is found to be on the same order of that of yttria-stabilized zirconia (YSZ), a traditional SOFC electrolyte material. As such, the ohmic loss due to oxygen transport through the tin layer must be considered in practical system cell design since the tin layer will usually be at least as thick as the electrolyte.

When Pd is well dispersed in the pores of the support, contact interaction with the support is maximized, Pd is less susceptible to poisoning by sulfur, and the sorbent has better long-term activity for adsorption of arsine and hydrogen selenide, but poorer adsorption capacity for Hg. As the contact interaction between Pd and the support is lessened the Pd becomes more susceptible to poisoning by sulfur, resulting in higher capacity for Hg, but poorer long-term performance for adsorption of arsenic and selenium.

Therefore the membranes were based on "CO sub(2)-philic" polymers that exhibit thermodynamically favorable Lewis acid:Lewis base and hydrogen bonding interactions with CO sub(2). CO sub(2)-philic polymers that are solid at ambient temperature include polyfluoroacrylate (PFA); polyvinyl acetate (PVAc); and amorphous polylactic acid (PLA). Literature CO sub(2) permeability values for PVAc and PLA are disappointingly low. The cast PFA membranes from this study had low permeabilities (45 barrers at 25 C) and very low CO sub(2)/H sub(2) selectivity of 1.4. CO sub(2)-philic polymers that are liquid at ambient conditions include polyethylene glycol (PEG), polypropylene glycol (PPG), polybutylene glycol with a linear -((CH sub(2)) sub(4)O)-repeat unit (i.e., polytetramethylene ether glycol (PTMEG)), polybutylene glycol (PBG) with a branched repeat unit, perfluoropolyether (PFPE), poly(dimethyl siloxane) (PDMS), and polyacetoxy oxetane (PAO). A small compound, glycerol triacetate (GTA) was also considered because it is similar in chemical structure to a trimer of PVAc. These liquids were tested as supported liquid membranes (SLM) and also (with the exception of PAO and GTA) as rubbery, crosslinked materials. Mixed gas permeability was measured using equimolar mixtures of CO sub(2) and H sub(2) feed streams at one atmosphere total pressure in steady-state flux experiments over the 298-423 K temperature range. The most promising SLMs were those composed of PEG, PTMEG, GTA, and PDMS. For example, at 37 C the PEG-, PTMEG-, GTA- and PDMS-based SLMs exhibited CO sub(2)/H sub(2) selectivity values of 11, 9, 9, and 3.5, respectively, and CO sub(2) permeability values of 800, 900, 1900, and 2000 barrers, respectively. Crosslinked versions of the PEG, PTMEG and PDMS membranes at 37 C exhibited selectivity values of 5, 6, and 3.5, respectively, and CO sub(2) permeability values of 50, 300, and 3000 barrers, respectively.

[Part 10 of 19] T2 - TEXAS CLEAN ENERGY PROJECT, ODESSA, ECTOR COUNTY, TEXAS. AN - 873128301; 14838-2_0010 AB - PURPOSE: The provision of approximately $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) to be located near the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Because of its multiple production capabilities, the plant is referred to as a poly-generation (polygen) plant. Summit Texas Clean Energy, LLC (Summit) would build the polygen plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 (I-20) along a Union Pacific Railroad (UPRR) line. The plant would be designed and constructed to capture approximately 90 percent of its CO2 and, during the demonstration phase of the plants operations, would sequester approximately 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and the linear facilities that would be constructed and operated to serve the plant, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This draft EIS evaluates the proposed project , operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. Under the proposed action, the Department of Energy would provide approximately 26 percent of the total capital cost of at least $1.73 billion (2009 dollars) on a costshare basis. POSITIVE IMPACTS: The TCEP would generate 1.7 billion net kilowatt-hours of electricity per year, which would be delivered to the electric grid system to help meet future demand. Operation would benefit the recovery of oil and gas in the portions of the Permian Basin that would receive CO2 from the TCEP. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. The technical, environmental, and financial data generated from the design, construction, and operation of the polygen plant would result in a commercial reference plant for the technology. NEGATIVE IMPACTS: Construction of the plant and linear facilities would result in the permanent loss of up to 876 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen oxides at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced after 95 percent removal through the syngas cleanup system. Annual non-captured CO2 emissions from operations would be approximately 300,000 tons per year. There would be a risk for potential ground water quality impacts associated with the limited potential for upward migration of CO2, or displaced native fluids through improperly abandoned deep wells or through natural fractures and faults in the rock. High-intensity lighting would have adverse impacts on night sky viewing conditions.

The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Because of its multiple production capabilities, the plant is referred to as a poly-generation (polygen) plant. Summit Texas Clean Energy, LLC (Summit) would build the polygen plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 (I-20) along a Union Pacific Railroad (UPRR) line. The plant would be designed and constructed to capture approximately 90 percent of its CO2 and, during the demonstration phase of the plants operations, would sequester approximately 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and the linear facilities that would be constructed and operated to serve the plant, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This draft EIS evaluates the proposed project , operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. Under the proposed action, the Department of Energy would provide approximately 26 percent of the total capital cost of at least $1.73 billion (2009 dollars) on a costshare basis. POSITIVE IMPACTS: The TCEP would generate 1.7 billion net kilowatt-hours of electricity per year, which would be delivered to the electric grid system to help meet future demand. Operation would benefit the recovery of oil and gas in the portions of the Permian Basin that would receive CO2 from the TCEP. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. The technical, environmental, and financial data generated from the design, construction, and operation of the polygen plant would result in a commercial reference plant for the technology. NEGATIVE IMPACTS: Construction of the plant and linear facilities would result in the permanent loss of up to 876 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen oxides at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced after 95 percent removal through the syngas cleanup system. Annual non-captured CO2 emissions from operations would be approximately 300,000 tons per year. There would be a risk for potential ground water quality impacts associated with the limited potential for upward migration of CO2, or displaced native fluids through improperly abandoned deep wells or through natural fractures and faults in the rock. High-intensity lighting would have adverse impacts on night sky viewing conditions.

The technical, environmental, and financial data generated from the design, construction, and operation of the polygen plant would result in a commercial reference plant for the technology. NEGATIVE IMPACTS: Construction of the plant and linear facilities would result in the permanent loss of up to 876 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen oxides at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced after 95 percent removal through the syngas cleanup system. Annual non-captured CO2 emissions from operations would be approximately 300,000 tons per year. There would be a risk for potential ground water quality impacts associated with the limited potential for upward migration of CO2, or displaced native fluids through improperly abandoned deep wells or through natural fractures and faults in the rock. High-intensity lighting would have adverse impacts on night sky viewing conditions.

AN - 873128231; 14838-2_0014 AB - PURPOSE: The provision of approximately $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) to be located near the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Because of its multiple production capabilities, the plant is referred to as a poly-generation (polygen) plant. Summit Texas Clean Energy, LLC (Summit) would build the polygen plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 (I-20) along a Union Pacific Railroad (UPRR) line. The plant would be designed and constructed to capture approximately 90 percent of its CO2 and, during the demonstration phase of the plants operations, would sequester approximately 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and the linear facilities that would be constructed and operated to serve the plant, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This draft EIS evaluates the proposed project , operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. Under the proposed action, the Department of Energy would provide approximately 26 percent of the total capital cost of at least $1.73 billion (2009 dollars) on a costshare basis. POSITIVE IMPACTS: The TCEP would generate 1.7 billion net kilowatt-hours of electricity per year, which would be delivered to the electric grid system to help meet future demand. Operation would benefit the recovery of oil and gas in the portions of the Permian Basin that would receive CO2 from the TCEP. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. The technical, environmental, and financial data generated from the design, construction, and operation of the polygen plant would result in a commercial reference plant for the technology.

[Part 1 of 19] T2 - TEXAS CLEAN ENERGY PROJECT, ODESSA, ECTOR COUNTY, TEXAS. AN - 873128132; 14838-2_0001 AB - PURPOSE: The provision of approximately $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) to be located near the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Because of its multiple production capabilities, the plant is referred to as a poly-generation (polygen) plant. Summit Texas Clean Energy, LLC (Summit) would build the polygen plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 (I-20) along a Union Pacific Railroad (UPRR) line. The plant would be designed and constructed to capture approximately 90 percent of its CO2 and, during the demonstration phase of the plants operations, would sequester approximately 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and the linear facilities that would be constructed and operated to serve the plant, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This draft EIS evaluates the proposed project , operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. Under the proposed action, the Department of Energy would provide approximately 26 percent of the total capital cost of at least $1.73 billion (2009 dollars) on a costshare basis. POSITIVE IMPACTS: The TCEP would generate 1.7 billion net kilowatt-hours of electricity per year, which would be delivered to the electric grid system to help meet future demand. Operation would benefit the recovery of oil and gas in the portions of the Permian Basin that would receive CO2 from the TCEP. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. The technical, environmental, and financial data generated from the design, construction, and operation of the polygen plant would result in a commercial reference plant for the technology. NEGATIVE IMPACTS: Construction of the plant and linear facilities would result in the permanent loss of up to 876 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen oxides at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced after 95 percent removal through the syngas cleanup system. Annual non-captured CO2 emissions from operations would be approximately 300,000 tons per year. There would be a risk for potential ground water quality impacts associated with the limited potential for upward migration of CO2, or displaced native fluids through improperly abandoned deep wells or through natural fractures and faults in the rock. High-intensity lighting would have adverse impacts on night sky viewing conditions.

[Part 18 of 19] T2 - TEXAS CLEAN ENERGY PROJECT, ODESSA, ECTOR COUNTY, TEXAS. AN - 873127862; 14838-2_0018 AB - PURPOSE: The provision of approximately $450 million in federal financial assistance for the planning, design, and construction of the Texas Clean Energy Project (TCEP) to be located near the city of Odessa in Ector County, Texas is proposed. The TCEP would use coal-based integrated gasification combined-cycle technology to generate 400 megawatts (MW) of electricity, and would capture carbon dioxide (CO2) for use in enhanced oil recovery (EOR) and eventual geologic sequestration. It would also produce urea, argon, and sulfuric acid for sale in commercial markets. Because of its multiple production capabilities, the plant is referred to as a poly-generation (polygen) plant. Summit Texas Clean Energy, LLC (Summit) would build the polygen plant on a 600-acre site adjacent to the community of Penwell and north of Interstate 20 (I-20) along a Union Pacific Railroad (UPRR) line. The plant would be designed and constructed to capture approximately 90 percent of its CO2 and, during the demonstration phase of the plants operations, would sequester approximately 3 million tons of CO2 per year by transporting it in pipelines to existing oil fields in the Permian Basin of West Texas for use in EOR operations by third-party buyers of the CO2. Following a three-year testing and operation demonstration phase, the polygen plant would continue in commercial operation for 30 to 50 years. The TCEP would consist of the polygen plant and the linear facilities that would be constructed and operated to serve the plant, including an electric transmission line, one or more process waterlines, a natural gas pipeline, a CO2 pipeline connector, a rail line connector, and two access roads that would connect the plant to existing roads. This draft EIS evaluates the proposed project , operational options that Summit is considering (four waterline options and six transmission line interconnection options), and a No Action Alternative. Under the proposed action, the Department of Energy would provide approximately 26 percent of the total capital cost of at least $1.73 billion (2009 dollars) on a costshare basis. POSITIVE IMPACTS: The TCEP would generate 1.7 billion net kilowatt-hours of electricity per year, which would be delivered to the electric grid system to help meet future demand. Operation would benefit the recovery of oil and gas in the portions of the Permian Basin that would receive CO2 from the TCEP. Implementation would demonstrate the commercial-readiness of clean coal technologies fully integrated with a polygen plant. The technical, environmental, and financial data generated from the design, construction, and operation of the polygen plant would result in a commercial reference plant for the technology. NEGATIVE IMPACTS: Construction of the plant and linear facilities would result in the permanent loss of up to 876 acres of mesquite shrub-grassland vegetation and its associated habitat functions for terrestrial species, including Texas horned lizard and 11 state-listed rare species. Direct impacts to air quality would result from construction activities and stationary source emissions (combustion turbine, flare, gasifier, cooling towers, sulfur recovery system, and coal handling) during project operations. Incremental increases of constituents would be up to nine percent for particulate matter with diameter equal to or less than 10 micrometers and up to 200 percent for nitrogen oxides at the points of maximum impact. An estimated 0.02 ton of mercury emissions per year would be produced after 95 percent removal through the syngas cleanup system. Annual non-captured CO2 emissions from operations would be approximately 300,000 tons per year. There would be a risk for potential ground water quality impacts associated with the limited potential for upward migration of CO2, or displaced native fluids through improperly abandoned deep wells or through natural fractures and faults in the rock. High-intensity lighting would have adverse impacts on night sky viewing conditions.

Thousands of wells are either in production or are planned for drilling. A typical well requires millions of gallons of water for the fracturing process, with varying amounts of flowback water coming back off the formation. Currently, much of the flowback water is stored in surface impoundments where it is treated and eventually re-injected. The rapid pace of the development of the Marcellus Shale necessitates equally rapid and thorough assessment of the environmental impacts of the drilling process. Our research aims to provide fundamental knowledge of the microbiology of these waters while also monitoring remediation efforts. Water samples were collected at various stages, from fracture water, flowback water, and short-term and long-term impoundments. The presence and number of microbes was determined using fluorescent DNA staining and microscopy. The microbial community was assessed using Fluorescent in situ Hybridization (FISH) with a suite of group-specific probes. Molecular microbial ecology techniques are planned to obtain a more detailed assessment of the microbial community. Targeted enrichments were done to isolate microbes potentially mediating important biogeochemical reactions in the impoundment waters. Lab-controlled experiments using these microbial enrichments can assess the impact of proposed biocides on the microbial community under various field-relevant conditions. Preliminary results suggest major differences in microbial communities among flowback waters from distinct wells with unique impoundment and treatment histories.

At various times during the past 200 years, Pennsylvania has had at least 30 spas that catered to the health and entertainment needs of both invalids and healthy people, and the waters of over 50 additional mineral springs were bottled and sold for their alleged health benefits as well. Spring waters in Pennsylvania vary in their temperature and chemical composition, which consists of varying concentrations of iron, magnesium, sulfur, hydrogen sulfide, radioactivity and salts. Specific springs became well-known for the treatment of specific diseases, while others were more renowned for their recreational activities. In this paper, the historical development of mineral springs in Pennsylvania is presented. We present information on the current status of these springs, from those that maintain viable commercial enterprises (e.g. Bedford Springs and Cambridge Springs), to those that are preserved as historical landmarks (e.g. Reading Mineral Springs and Frankfort Springs), and we relate our attempts at finding the remains of some long-lost and well-hidden sites, such as Parker Mineral Springs in McKean County.

The work falls into four categories: 1) chemical and microbiological characterization of flowback and produced waters; 2) development of more effective technologies to treat or manage produced and flowback waters; 3) monitoring of air emissions from Marcellus Shale gas wells to determine impact on regional air quality; and 4) determining the impact of Marcellus development on sensitive indicator species. Marcellus Shale gas flowback and produced waters are being characterized to achieve a holistic understanding of the chemistry of these waters and the microbial consortia that live in them. This information will be used to design effective treatment for the produced/flowback waters and to determine the chemical and isotopic signature for such waters so that they can be identified when commingled with surface water or shallow groundwater. NETL is monitoring air emissions from oil and gas operations using a mobile laboratory that is equipped to measure 52 VOC's, ozone, SO (sub 2) , NO (sub x) , PM (sub 2.5) and PM (sub 10) , particle and gas phase ions (sulfate, nitrate, nitrite, phosphate, bromide, and fluoride), ammonia, organic and elemental carbon in aerosols, visibility impairment (haze), methane, and radon. NETL also has been examining the impact of access road and drill pad construction on sensitive species. Specifically, NETL has funded West Virginia University to examine the impact of Marcellus Shale gas development on two migratory songbirds whose populations have been in decline since 1960. Further, NETL in conjunction with Penn State's Dirt and Gravel Roads Group, Clarion University and the U.S. Geological Survey have been looking at the impact of different methods of access road construction on sedimentation in nearby streams and the resulting impact on macroinvertebrate populations. The current status of these studies including significant outcomes will be presented.

This study examined the current impacts of unpaved roads built to service the oil industry in the Allegheny National Forest on sedimentation and stream ecology. Two adjacent watersheds, similar in size and topography but having low and very high road density, were identified for study. The Grunder Run study area has a contributing drainage of 12.4 square km, with a road density of 6.9 km per square km of drainage, and represented a watershed developed for oil and gas extraction. The Hedgehog Run study area served as a forested control site with a contributing drainage of 11.1 square km and road density of 1.2 km per square km. Both streams were instrumented with stream flow and water quality monitors with data transmitted via satellite telemetry. A rainfall simulation device was used to create repeatable rainfall events (1.5 cm per 30 min) and to collect sediment load data from selected 30.5 m sections of road. Of 14 sites measured, average sediment runoff equaled 11.2 kg per study, or 370 kg per kilometer for each 30 min simulated rainfall event. As a practical tool for the preliminary evaluation of sediment runoff potential, an index was developed using a GIS model based on high resolution elevation data derived from LIDAR to evaluate topographic parameters that significantly affect rainfall/runoff relationships for road segments. The model is being used to prioritize unpaved road-segments prior to the implementation of restoration and sedimentation management plans. Macroinvertebrates were collected during the early summer, late summer and fall from two sites each in study area. Surprisingly, macroinvertebrate fauna in both watersheds were similar in terms of overall taxa richness, EPT (mayfly/stonefly/caddisfly) richness values, and diversity indices. Preliminary analyses indicate that the presence/absence of selected macroinvertebrate indicator species may provide more specific indication of road-generated sediment impact than do total population indices.

Black shale cuttings from deep horizontal boreholes are different. When cuttings are brought to the surface, the reduced minerals in them are exposed to air and fresh water for the first time. Oxides of many elements are more water-soluble and mobile than the metallic or reduced forms. The concerns are magnified by the large quantities of drill cuttings. The mass of black shale removed from a lateral borehole that is 30 cm across and up to 2 km long may exceed several hundred tons. Samples of drill cuttings, core, and outcrops of the lower, middle and upper parts of the Marcellus Shale were chemically analyzed. Carbon, sulfur and hydrogen were assayed by Controlled Atmosphere Programmed Temperature Oxidation (CAPTO). Scanning electron microscopy and elemental analyses were run on select samples. A leaching procedure followed by Inductively Coupled Plasma (ICP) analyses was used to detect "toxic" metals such as arsenic, lead, mercury, and selenium. An ICP analysis of a composite sample was performed to determine bulk rock elemental composition. Radioactivity was measured using a low background radiation analyzer. The CAPTO analyses showed organic and inorganic carbon in the samples, hydrogen as free moisture, hydrocarbons and bound water on clays, and sulfur in both sulfides and sulfates. The ICP analysis of the composite sample showed the major components of the rock to be Al, Ca, Fe, K, Mg, Na, S, Si, and Ti, which is not unexpected for pyritic, clay-rich, black shale. Minor elements detected by the ICP at levels above the minimum reporting limit included As, B, Ba, Cd, Co, Cr, Cu, Li, Mn, Mo, Ni, P, Pb, Sn, Sr, V, Zn, and Zr. The alpha radiation counts on the bulk rock samples ranged from background levels to about 8 times above background. Analysis on the leachate prepared for the ICP tests showed alpha counts at background levels. The preliminary results suggest that black shales do contain small but detectable amounts of heavy metals and other elements that can be detrimental to the environment if mobilized and concentrated. Additional analyses are needed to better define the fate and transport of leachate from black shale cuttings, and identify potential environmental hazards.

Three initial water saturations were used to form three different methane-hydrate saturations in each medium. X-ray computed tomography (CT) was used to observe location-specific density changes caused by hydrate formation and flowing water. Gas-permeability measurements in each test for the dry, moist, frozen, and hydrate-bearing states are presented. As expected, the effective permeabilities (intrinsic permeability of the medium multiplied by the relative permeability) of the moist sands decreased with increasing moisture content. In a series of tests on a single sample, the effective permeability typically decreased as the pore space became more filled in the order of dry, moist, frozen, and hydrate-bearing. In each test, water was flowed through the hydrate-bearing medium and we observed the location-specific changes in water saturation using CT scanning. We compared our data to a number of models, and our relative permeability data compare most favorably with models in which hydrate occupies the pore bodies rather than the pore throats. Inverse modeling (using the data collected from the tests) will be performed to extend the relative permeability measurements.

These materials were of great interest to the early geologists of the region. This field trip discusses these products in the context of early grain milling, iron furnaces, and allied industries of Ohio and Pennsylvania in the late eighteenth and early nineteenth century, with a focus on two publicly accessible sites: McConnells Mill Park in western Pennsylvania, and Mill Creek Park in eastern Ohio. These parks contain publicly accessible gristmills and iron furnaces, and outcrops. We also provide new observations on cultural materials related to these industries, especially iron-furnace slag and millstones.

One promising approach is CO (sub 2) capture and permanent storage in deep geologic formations, such as depleted oil and gas reservoirs, unminable coal seams, and deep brine-containing (saline) formations. However, successful implementation of geologic storage projects will require robust monitoring, verification, and accounting (MVA) tools. This article deals with all aspects of MVA activities associated with such geologic CO (sub 2) storage projects, including site characterization, CO (sub 2) plume tracking, CO (sub 2) flow rate and injection pressure monitoring, leak detection, cap-rock integrity analysis, and long-term postinjection monitoring. Improved detailed decision tree diagrams are presented covering the five stages of a geologic storage project. These diagrams provide guidance from the point of site selection through construction and operations to closure and postclosure monitoring. Monitoring, verification, and accounting techniques (both well-established and promising new developments) appropriate for various project stages are discussed. Accomplishments of the Department of Energy (DOE) Regional Carbon Sequestration Partnerships field projects serve as examples of the development and application to geologic storage of MVA tools, such as two-dimensional and three-dimensional seismic and microseismic, as well as the testing of new cost-effective monitoring technologies. Although it is important that MVA and computer simulation efforts be carefully integrated to ensure long-term success of geologic storage projects, this article is limited to a discussion of MVA activities. This article is an extension of a report published in 2009 by the DOE National Energy Technology Laboratory titled, "Best Practices for Monitoring, Verification, and Accounting of CO (sub 2) Stored in Deep Geologic Formations," to which interested readers are referred for more details on MVA tools. Ultimately, a robust MVA program will be critical for establishing carbon capture and storage as a viable greenhouse gas mitigation strategy.

S. Department of Energy, and the U. S. Geological Survey completed the BPXA-DOE-USGS Mount Elbert Gas Hydrate Stratigraphic Test Well (Mount Elbert well) in the Milne Point Unit on the Alaska North Slope. The program achieved its primary goals of validating the pre-drill estimates of gas hydrate occurrence and thickness based on 3-D seismic interpretations and wireline log correlations and collecting a comprehensive suite of logging, coring, and pressure testing data. The upper section of the Mount Elbert well was drilled through the base of ice-bearing permafrost to a casing point of 594 m (1950 ft), approximately 15 m (50 ft) above the top of the targeted reservoir interval. The lower portion of the well was continuously cored from 606 m (1987 ft) to 760 m (2494 ft) and drilled to a total depth of 914 m. Ice-bearing permafrost extends to a depth of roughly 536 m and the base of gas hydrate stability is interpreted to extend to a depth of 870 m. Coring through the targeted gas hydrate bearing reservoirs was completed using a wireline-retrievable system. The coring program achieved 85% recovery of 7.6 cm (3 in) diameter core through 154 m (504 ft) of the hole. An onsite team processed the cores, collecting and preserving approximately 250 sub-samples for analyses of pore water geochemistry, microbiology, gas chemistry, petrophysical analysis, and thermal and physical properties. Eleven samples were immediately transferred to either methane-charged pressure vessels or liquid nitrogen for future study of the preserved gas hydrate. Additional offsite sampling, analyses, and detailed description of the cores were also conducted. Based on this work, one lithostratigraphic unit with eight subunits was identified across the cored interval. Subunits II and Va comprise the majority of the reservoir facies and are dominantly very fine to fine, moderately sorted, quartz, feldspar, and lithic fragment-bearing to -rich sands. Lithostratigraphic and palynologic data indicate that this section is most likely early Eocene to late Paleocene in age. The examined units contain evidence for both marine and non-marine lithofacies, and indications that the depositional environment for the reservoir facies may have been shallower marine than originally interpreted based on pre-drill wireline log interpretations. There is also evidence of reduced salinity marine conditions during deposition that may be related to the paleo-climate and depositional conditions during the early Eocene.

The well was conducted as part of a Cooperative Research Agreement (CRA) project co-sponsored since 2001 by BP Exploration (Alaska), Inc. (BPXA) and the U. S. Department of Energy (DOE) in collaboration with the U. S. Geological Survey (USGS) to help determine whether ANS gas hydrate can become a technically and commercially viable gas resource. Early in the effort, regional reservoir characterization and reservoir simulation modeling studies indicated that up to 0.34 trillion cubic meters (tcm; 12 trillion cubic feet, tcf) gas may be technically recoverable from 0.92 tcm (33 tcf) gas-in-place within the Eileen gas hydrate accumulation near industry infrastructure within ANS MPU, Prudhoe Bay Unit (PBU), and Kuparuk River Unit (KRU) areas. To further constrain these estimates and to enable the selection of a test site for further data acquisition, the USGS reprocessed and interpreted MPU 3D seismic data provided by BPXA to delineate 14 prospects containing significant highly-saturated gas hydrate-bearing sand reservoirs. The "Mount Elbert" site was selected to drill a stratigraphic test well to acquire a full suite of wireline log, core, and formation pressure test data. Drilling results and data interpretation confirmed pre-drill predictions and thus increased confidence in both the prospect interpretation methods and in the wider ANS gas hydrate resource estimates. The interpreted data from the Mount Elbert well provide insight into and reduce uncertainty of key gas hydrate-bearing reservoir properties, enable further refinement and validation of the numerical simulation of the production potential of both MPU and broader ANS gas hydrate resources, and help determine viability of potential field sites for future extended term production testing. Drilling and data acquisition operations demonstrated that gas hydrate scientific research programs can be safely, effectively, and efficiently conducted within ANS infrastructure. The program success resulted in a technical team recommendation to project management to drill and complete a long-term production test within the area of existing ANS infrastructure. If approved by stakeholders, this long-term test would build on prior arctic research efforts to better constrain the potential gas rates and volumes that could be produced from gas hydrate-bearing sand reservoirs.

We have previously demonstrated that the embedding of metal nanoparticles into a nanostructured ceramic matrix can result in unusually active and sinter-resistant nanocomposite oxygen carrier materials for CLC which maintain high reactivity and high-temperature stability even when sulfur contaminated fuels are used in CLC. Here, we propose a novel process scheme for in situ desulfurization of syngas with simultaneous CO sub(2)-capture in chemical looping combustion by using these robust nanocomposite oxygen carriers simultaneously as sulfur-capture materials. We found that a nanocomposite Cu-BHA carrier can indeed strongly reduce the H sub(2)S concentration in the fuel reactor effluent. However, during the process the support matrix is also sulfidized and takes part in the redox process of CLC. This results in SO sub(2) production during the reduction of the oxygen carrier and thus limits the degree of desulfurization attainable with this kind of carrier. Nevertheless, the results suggest that simultaneous desulfurization and CO sub(2) capture in CLC is feasible with Cu as oxygen carrier as long as appropriate carrier support materials are chosen, and could result in a novel, strongly intensified process for low-emission, high efficiency combustion of sulfur contaminated fuel streams.

Four such MDT tests, ranging from six to twelve hours duration, and including a series of flow, sampling, and shut-in periods of various durations, were conducted. Locations for the testing were selected based on NMR and other log data to assure sufficient isolation from reservoir boundaries and zones of excess free water. Test stages in which pressure was reduced sufficiently to mobilize free water in the formation (yet not cause gas hydrate dissociation) produced readily interpretable pressure build-up profiles. Build-ups following larger drawdowns consistently showed gas-hydrate dissociation and gas release (as confirmed by optical fluid analyzer data), as well as progressive dampening of reservoir pressure build-up during sequential tests at a given MDT test station. History matches of one multi-stage, 12-h test (the C2 test) were accomplished using five different reservoir simulators: CMG-STARS, HydrateResSim, MH21-HYDRES, STOMP-HYD, and TOUGH+HYDRATE. Simulations utilized detailed information collected across the reservoir either obtained or determined from geophysical well logs, including thickness (11.3m, 37 ft.), porosity (35%), hydrate saturation (65%), both mobile and immobile water saturations, intrinsic permeability (1000mD), pore water salinity (5ppt), and formation temperature (3.3-3.9 degree C).

Here, we investigate, by means of controlled experiments and computed tomography (CT) imaging, the preferential mode of gas migration in three-dimensional samples of water-saturated silica-sand and silica-silt sediments. Our experimental system allowed us to independently control radial and axial confining stresses and pore pressure while performing continuous x-ray CT scanning. The CT image analysis of the three-dimensional gas migration provides the first experimental confirmation that capillary invasion preferentially occurs in coarse-grained sediments whereas grain displacement and conduit openings are dominant in fine-grained sediments. Our findings allow us to rationalize prior field observations and pore-scale modeling results, and provide critical experimental evidence to explain the means by which conduits for the transit of methane gas may be established through the gas hydrate stability zone in oceanic sediments, and cause large episodic releases of carbon into the deep ocean.

A numerical study was also performed to develop and analyze empirical relations that describe the impacts of hydrate accumulation habits within pore space (e.g., pore filling or grain cementing) on multiphase fluid migration. In the experimental study, water was injected into a hydrate-bearing sand sample that was monitored using an X-ray CT scanner. The CT images were converted into numerical grid elements, providing intrinsic sample data including porosity and phase saturations. The impacts of hydrate accumulation were examined by adapting empirical relations into the flow simulations as additional relations governing the evolution of absolute permeability of hydrate bearing sediment with hydrate deposition. The impacts of pore space hydrate accumulation habits on fluid migration were examined by comparing numerical predictions with experimentally measured water saturation distributions and breakthrough curves. A model case with 3-D heterogeneous initial conditions (hydrate saturation, porosity, and water saturation) and pore body-preferred hydrate accumulations best captured water migration behavior through the hydrate-bearing sample observed in the experiment. In the best matching model, absolute permeability in the hydrate bearing sample does not decrease significantly with increasing hydrate saturation until hydrate saturation reaches about 40%, after which it drops rapidly, and complete blockage of flow through the sample can occur as hydrate accumulations approach 70%. The result highlights the importance of permeability modification due to hydrate accumulation habits when predicting multiphase flow through high-saturation, reservoir quality hydrate-bearing sediments.

Hydrogen still permeates through the bi-layered Pd sub(4)S/Pd structure, indicating that the Pd sub(4)S surface is active for H sub(2) dissociation; the low hydrogen permeability of the Pd sub(4)S film is responsible for the decreased rate of hydrogen transport. In this work, the hydrogen permeability of Pd sub(4)S was determined experimentally in the 623-773 K temperature range. Bi-layered Pd sub(4)S/Pd foils were produced by exposing pure Pd foils to H sub(2)S. H sub(2) fluxes through the bi-layered Pd sub(4)S/Pd foils were measured during exposure to both pure H sub(2) and a 1000 ppm H sub(2)S in H sub(2) gas mixture. Our results show that H sub(2)S slows hydrogen permeation through Pd mainly by producing a Pd sub(4)S film on the Pd surface that is roughly an order-of-magnitude less permeable to hydrogen (k sub(Pd4S) = 10 super(-7.5) exp(-0.22 eV/k sub(BT)) molH sub(2)/m/s/Pa super(1/2)) than pure Pd. The presence of H sub(2)S in the gas stream results in greater inhibition of hydrogen transport than can be explained by the very low permeability of Pd sub(4)S. H sub(2)S may block H sub(2) dissociation sites at the Pd sub(4)S surface. Research highlights: Direct measurements of the hydrogen permeability of Pd sub(4)S show that H sub(2)S degrades the performance of Pd membranes primarily by producing a Pd sub(4)S film with low intrinsic H atom permeability - about an order-of-magnitude lower than that of Pd. The Pd sub(4)S films allow H atom transport; they do not completely block the H sub(2) flux across the membrane. In addition to causing formation of low-permeability Pd sub(4)S, H sub(2)S in the feed gas also lowers H sub(2) flux directly, possibly by blocking H sub(2) dissociation sites.

In this literature review on oil shale dielectric properties, we found that at low temperatures ( 200 C) and constant frequency, e' generally increases with temperature regardless of grade while e" fluctuates. At these temperatures, maximum values for both e' and e" differ based upon oil shale grade. Formation fluids, mineral-bound water, and oil shale varve geometry also affect measured dielectric properties. This review presents and synthesizes prior work on the influence of applied frequency, oil shale grade, water, and temperature on the dielectric properties of oil shales that can aid in the future development of frequency- and temperature-specific in situ retorting technologies and oil shale grade assay tools.

This model has been validated through comparison with several experiments. For a range of stable viscosity ratios (M-mu (sub injected,nwf) /mu (sub defending,wf) > or =1), we had increased the capillary number, N (sub c) and studied the way in which the flows deviate from fractal capillary fingering at a characteristic time and become compact for realistic capillary numbers. This crossover has enabled predictions for the dependence of the flow behavior upon capillary number and viscosity ratio. Our results for the crossover agreed with earlier theoretical predictions, including the universality of the leading power-law indicating its independence of details of the porous medium structure. In this article, we have observed a similar crossover from initial fractal viscous fingering (FVF) to compact flow, for large capillary numbers and unstable viscosity ratios M<1. In this case, we increased the viscosity ratio from infinitesimal values, and studied the way in which the flows deviate from FVF at a characteristic time and become compact for non-zero viscosity ratios. This crossover has been studied using both our pore-level model and micro-fluidic flow-cell experiments. The same characteristic time, tau =1/M (super 0.7) , satisfactorily describes both the pore-level results for a range of large capillary numbers and the micro-fluidic flow cell results. This crossover should lead to predictions similar to those mentioned above.

Determining the source of these dissolved salts and understanding local and basinal variations in TDS have direct relevance to exploration methodologies and water management and reclamation. A series of flowback waters have been collected from drilling operations in a geographic region spanning approximately 375 km, from northeastern to southwestern Pennsylvania. Most (super 87) Sr/ (super 86) Sr values fall within a narrow range, from 0.7101 to 0.7112; samples from two adjacent wells in Westmoreland County, Pennsylvania, define a second grouping (0.7120-0.7121). This bimodal distribution of flowback values could be a result of hydrofracturing water interacting with different producing members of the Marcellus Formation, or lateral (facies) variations in the isotopic composition of formation salts. The relatively tight clustering of values among geographically distant sites argues against variable influxes of brines from adjacent formations. Marcellus flowback waters contain notably elevated levels of barium and strontium (up to 12, 000 and 5, 000 mg/L, respectively, for the samples in this study). The Ba/Sr ratios of the flowback fluids measured here also vary systematically with geographic location, The combination of Ba/Sr and (super 87) Sr/ (super 86) Sr provide a method for uniquely identifying regional variations in flowback waters. The (super 87) Sr/ (super 86) Sr ratios of Marcellus waters measured here fall well above Phanerozoic seawater values. Thus, while the Marcellus brines may have a significant seawater component, this has clearly been augmented by a high- (super 87) Sr/ (super 86) Sr source, possibly originating from dissolution of radiogenic minerals within the shale. Ongoing leaching studies of core material from the Marcellus Formation and adjacent units will provide additional insight into the origins of salts in Marcellus waters.

The HEM surveys identified areas of concern in each of the impoundments investigated. In most cases, these were areas where filtrate was emerging high on the downstream embankment and represented an erosion risk. Of greater concern, the HEM survey identified thick bodies of slurry that remained unconsolidated and were buried deep beneath the embankment"s crest of some impoundments. Ground confirmation activities indicated that HEM survey interpretations provided an accurate representation of the conductivity distribution within coal-waste impoundments. We then interpreted the conductivity/depth images from the HEM surveys to provide a snapshot of hydrologic conditions that existed within the impoundment at the time of the survey. Resistivity profiles were obtained at the inactive impoundment along segments of flight lines from the HEM survey. HEM and resistivity surveys detected a conductive layer at a depth that was interpreted to be unconsolidated coal slurry. The methods also detected conductive bodies at a depth that were interpreted to be flooded mine works. Resistivity surveys from these segments corroborated HEM data, thereby providing independent confirmation of the HEM data and its processing. The resistivity and HEM surveys indicated a resistive surface layer where the coarse coal refuse was placed. Beneath the resistive surface layer is a conductive layer of unconsolidated or partially consolidated coal slurry. These highly loaded bodies of unconsolidated slurry are susceptible to solifluction, which can threaten embankment stability. Underground mine workings were identified in the HEM data from one impoundment.

The CO (sub 2) flux was measured at two Allegheny County, PA discharges that drain abandoned mines in the Pittsburgh coal seam. Both calcium sulfate-type waters emanate from collapsed mine portals located on a hillside above the Youghiogheny River and flow over waterfalls of approximately 10 to 15 meters before discharging into the river. Site 1 portal water had a pH of 6.1 and 159 mg/L CaCO (sub 3) alkalinity; Site 2 portal water had a pH of 5.1, but no measurable alkalinity. An Anton Paar CarboQC (super TM) CO (sub 2) meter was used to measure the concentration of dissolved CO (sub 2) . The flux of CO (sub 2) was calculated using discharge data and the difference in dissolved CO (sub 2) from the portals to the bottom of each waterfall. The CO (sub 2) concentrations at the source portals were ca. 0.21 g/L at Site 1 and ca. 0.14 g/L at Site 2. The CO (sub 2) concentrations decreased by approximately 85% from the portals to the bottoms of the falls at both sites. The estimated CO (sub 2) flux was 225 kg/day at Site 1 and 20 kg/day at Site 2. The ratio of CO (sub 2) (dissolved)/CO (sub 2) (atmospheric) was nearly equal 300 and 230 at Sites 1 and 2, respectively. Using data for Pennsylvania (Cravotta, 2008), we calculated CO (sub 2) fluxes for 90 other mine drainage sources and obtained values ranging between 5 and 30,000 kg/day, with an average of 1,300 kg/day. The estimated total daily flux from all sites with available data was ca. 110,000 kg. The calculation assumed that the CO (sub 2) in these mine waters completely degassed to atmospheric equilibrium and therefore represents a maximum flux value. The data indicate that mine drainage can contain dissolved CO (sub 2) orders of magnitude greater than atmospheric equilibrium; further study is needed to evaluate its importance to the overall carbon cycle.

Changes in formation brine chemistry during CO (sub 2) injection were monitored in field-collected brine samples (see complementary abstract by Thordsen et al.). Our investigation focuses on laboratory-scale experiments using natural samples from the Tuscaloosa formation. Results from our work will be compared with results from the field study to determine whether laboratory-scale experiments may be used to predict changes in CO (sub 2) storage formation fluid chemistry due to CO (sub 2) -water-rock interactions. Core samples from the Tuscaloosa loose sediment injection zone were collected and preserved, and natural brines were collected via U-tube, prior to CO (sub 2) injection. XRD analysis of the sandstone showed mainly quartz, chert and feldspar with some volcanic rock and metamorphic rock fragments. Iron-chlorite (chamosite) was present at about 14 % wt. of the core sample, and only a small fraction can be attributed to carbonate minerals. The brine was a natural Na-Ca-Cl brine with 152,000 mg/L TDS. The experiment was conducted using a rocking autoclave at 350 bar pressure and 125 degrees C constant temperature for a reaction period of 120 days, which included 40 days of brine-rock mixing in the absence of CO (sub 2) to ensure steady-state conditions prior to CO (sub 2) injection. After CO (sub 2) injection, solution pH decreased, and we observed increases in major cations (Ca, Mg, K). Fe(II) and total Fe increased immediately after injection; Fe(II) declined to pre-CO (sub 2) levels within 48 hours, and total Fe rose towards the end of the experiment. These data suggest a rapid reaction of Fe(II)-bearing carbonate minerals and/or iron-chlorite phases upon CO (sub 2) injection, with subsequent geochemical reactions involving Fe-bearing solid phases. Additionally, iron-chlorite dissolution in the presence of CO (sub 2) is possible since Al, Si, and Mg concentration changed over time. These results suggest a rapid initial reaction of Lower Tuscaloosa natural brine and sandstone upon CO (sub 2) injection, with subsequent precipitation and dissolution reactions occurring in the presence of CO (sub 2) -charged brine.

Recent CLC studies have considered the more technically difficult problem of reactions between abundant solid fuels (i.e. coal and waste streams) and solid metal oxides. A definitive reaction mechanism has not been reported for CLC reaction of solid fuels. It has often been assumed that the solid/solid reaction is slow and therefore requires that reactions be conducted at temperatures high enough to gasify the solid fuel, or decompose the metal oxide. In contrast, data presented in this paper demonstrates that solid/solid reactions can be completed at much lower temperatures, with rates that are technically useful as long as adequate fuel/metal oxide contact is achieved. Density functional theory (DFT) simulations as well as experimental techniques such as thermo-gravimetric analysis (TGA), flow reactor studies, in situ X-ray photo electron spectroscopy (XPS), in situ X-ray diffraction (XRD) and scanning electron microscopy (SEM) are used to evaluate how the proximal interaction between solid phases proceeds. The data indicate that carbon induces the Cu-O bond breaking process to initiate the combustion of carbon at temperatures significantly lower than the spontaneous decomposition temperature of CuO, and the type of reducing medium in the vicinity of the metal oxide influences the temperature at which the oxygen release from the metal oxide takes place.

This acidification has the potential to enhance water-rock interactions such as dissolution and precipitation of carbonate minerals. As a result, the integrity of the caprock may be altered by the acidified brine, thereby affecting the potential for leakage of the injected CO (sub 2) . To investigate the impact of leakage of CO (sub 2) -acidified brine through caprock fractures, a flow-through experiment was conducted on a fractured sample of caprock. This caprock is a specimen of the Amherstburg formation in the Michigan sedimentary basin, and is a fine-grained carbonate composed primarily of calcite and dolomite. This formation overlies the Bass Islands Dolostone, the target formation for an injection demonstration project. The core sample was artificially fractured prior to the experiment and encased in epoxy to prevent lateral flow. Experimental temperature and pressure conditions were 40 degrees C and 10 MPa, corresponding to injection at depths of approximately 1 km. The initial brine composition was representative of water previously reacted with the injection formation minerals under CO (sub 2) -saturated conditions. The flow-through experiment was conducted within a medical-grade CT scanner allowing for continued scanning of the core during active injection. Additionally, pre- and post-injection scans were taken with a micro-CT scanner providing voxel resolution of 27 mu m, roughly five times better than that achieved via the medical scanner. Mineral dissolution along the fracture network is evident in both the CT imaging and analysis of brine effluent composition. After one week of brine flow, the micro-CT scans show increases in fracture aperture as large as 2 mm which in some cases is more than a 20-fold increase in aperture width. Further work will apply synchrotron-based X-ray diffraction CT and X-ray fluorescence imaging methods in an attempt to couple geochemical and spatial alterations within single pores along a flowpath. The ability to observe geochemical reactions at different scales provides the unique opportunity to relate how mineral dissolution and precipitation at the pore-scale impacts core-scale flow characteristics relevant to understanding the evolution of caprock integrity.

A previously-developed gasification CFD model was modified to account for coal particle density and size distributions as produced from a typical rod mill. Postprocessing tools were developed for analysis of particle-wall impact properties. For the two-stage upflow gasifier, three different simulations are presented: two (Case 1 and Case 2) used the same devolatilization and char conversion models from the literature, while Case 3 used a different devolatilization model. The Case 1 and Case 3 solutions used average properties of a Pittsburgh #8 seam coal (d =108I14m, SG=1.373), while Case 2 was obtained by injecting and tracking all of the series of 28 different coal particle density and size mass fractions obtained by colleagues at PSU as a part of the current work, for this same coal. Simulations using the two devolatilization models (Case 1 and Case 3) were generally in reasonable agreement. Differences were observed between the single-density solution and the density/size partitioned solution (Case 1 and Case 2). The density/size partitioned solution predicted nominally 10% less CO and over 5% more H2 by volume in the product gas stream. Particle residence times and trajectories differed between these two solutions for the larger density/size fractions. Fixed carbon conversion was 4.3% higher for the partitioned solution. Particle-wall impact velocities did not vary greatly. Grid independence studies for the two-stage upflow gasifier geometry showed that the grid used in the comparison studies was adequate for predicting exit gas composition and wall impact velocities. Validation studies using experimental data for the Pittsburgh #8 coal from the SRI International pressurized coal flow reactor (PCFR) at 30 atmospheres indicated adequate agreement for gasification and combustion cases, but poor agreement for a pyrolysis case. Simulation of a single-stage downflow gasifier yielded an exit gas composition that was in reasonable agreement with published data. Entrained-flow gasifiers are simulated via CFD, including coal particle density/size variations. The two-stage gasifier density/size partitioned solution predicted 10% less exit CO and 5% more H2 than a single-density solution. Particle residence times differed for the larger density/size fractions. Fixed carbon conversion was 4.3% higher. Simulation of a single-stage gasifier yielded exit gas composition in reasonable agreement with published data.

To provide solutions for energy and the environment, the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) and its research partners in industry and academia are relying increasingly on the use of sophisticated computer-aided process design and optimization tools. In this paper, we describe recent progress toward developing an Advanced Process Engineering Co-Simulator (APECS) for the high-fidelity design, analysis, and optimization of energy plants. The APECS software system combines steady-state process simulation with multiphysics-based equipment simulations, such as those based on computational fluid dynamics (CFD). These co-simulation capabilities enable design engineers to optimize overall process performance with respect to complex thermal and fluid flow phenomena arising in key plant equipment items, such as combustors, gasifiers, turbines, and carbon capture devices. In this paper we review several applications of the APECS co-simulation technology to advanced energy systems, including coal-fired energy plants with carbon capture. This paper also discusses ongoing co-simulation R&D activities and challenges in areas such as CFD-based reduced-order modeling, knowledge management, advanced analysis and optimization, and virtual plant co-simulation. Continued progress in co-simulation technology - through improved integration, solution, and deployment - will have profound positive impacts on the design and optimization of high-efficiency, near-zero emission fossil energy systems.

A serial batch characterization method has been developed at the National Energy Technology Laboratory that can be completed in 2-3days to serve as a screening tool. The procedure provides an estimate of cumulative metals release under varying pH conditions, and leaching the sample at increasing liquid/solid ratios can indicate the rate at which this process will occur. This method was applied to eight fly ashes, adapted to the acidic or alkaline nature of the ash. The leachates were analyzed for 30 elements. The test was run in quadruplicate, and the relative standard deviation (RSD) was used as a measure of method reproducibility. RSD values are between 0.02 and 0.70, with the majority of the RSD values less than 0.3. The serial batch leaching procedure was developed as a simple, relatively quick, yet comprehensive method of estimating the risk of heavy metal release from fly ash when it is exposed to natural fluids, such as acid rain or groundwater. Tests on a random selection of coal fly ashes have shown it to be a reasonably precise method for estimating the availability and long-term release of cations from fly ash.

Both structure and reducibility of the oxides could be tailored by adjusting the la content across the entire range of La:Ce-ratios. The reducibility of the Au-free oxides shows an optimum at [inline image]25% la content, which can be traced back to improved oxygen mobility due to formation of oxygen vacancies and to the formation of more strongly bound oxygen upon la addition. Deposition of Au onto these oxides gives rise to an additional, low-temperature reduction peak, presumably due to hydrogen spill-over from the noble metal onto the oxide support. The WGS activity of Au/La sub(x)Ce sub(1-x)O sub(2-0.5x) catalysts correlates closely with the reducibility of the oxide supports, and hence with la content, demonstrating that carefully controlled synthesis of nanostructured catalysts with uniform, tailored composition allows for fine control of reactive properties of these materials, and might ultimately open the way towards a more rational design of catalysts.

The effluents from 15 different gasification facilities were considered to assess the impact of fuel composition on anode susceptibility to contamination. For each syngas case, the study considers the magnitude of contaminant exposure resulting from operation of a warm gas cleanup unit at two different temperatures and operation of a nickel-based SOFC at three different temperatures. Contaminant elements arsenic (As), phosphorous (P), and antimony (Sb) are predicted to be present in warm gas cleanup effluent and will interact with the nickel (Ni) components of a SOFC anode. Phosphorous is the trace element found in the largest concentration of the three contaminants and is potentially the most detrimental. Poisoning was found to depend on the composition of the syngas as well as system operating conditions. Results for all trace elements tended to show invariance with cleanup operating temperature, but results were sensitive to syngas bulk composition. Synthesis gas with high steam content tended to resist poisoning.

Computed tomography scanning provides a unique view of rock fractures, allowing the measurement of fracture wall-roughness, without destroying the initial rock sample. For this computational fluid dynamics study, we used several different methods to obtain three-dimensional meshes of a computed tomography scanned fracture in Berea sandstone. These volumetric meshes had different wall-roughnesses, which we characterized using the Joint Roughness Coefficient and the fractal dimension of the fracture profiles. We then related these macroscopic roughness parameters to the effective flow through the fractures, as determined from Navier-Stokes numerical models. Thus, we used our fracture meshes to develop relationships between the observed roughness properties of the fracture geometries and flow parameters that are of importance for modeling flow through fractures in field scale models. Fractures with high Joint Roughness Coefficients and fractal dimensions were shown to exhibit tortuous flow paths, be poorly characterized by the mean geometric aperture, and have a fracture transmissivity 35 times smaller than the smoother modeled fracture flows.

Integrated gasification combined cycle (IGCC) plant designs can create a high-hydrogen fuel using a water-gas shift reactor and subsequent CO2 separation. The IGCC's air separation unit produces a volume of N2 roughly equivalent to the volume of H2 in the gasifier product stream, which can be used to help reduce peak flame temperatures and NOx in the diffusion flame combustor. Placement of this diluent in either the air or fuel streams is a matter of practical importance, and it has not been studied to date for LDI combustion. The current work discusses how diluent placement affects diffusion flame temperatures, residence times, and stability limits, and their resulting effects on NOx emissions. From a peak flame temperature perspective, greater NOx reduction should be attainable with fuel dilution rather than air or independent dilution in any diffusion flame combustor with excess combustion air, due to the complete utilization of the diluent as a heat sink at the flame front, although the importance of this mechanism is shown to diminish as flow conditions approach stoichiometric proportions. For simple LDI combustor designs, residence time scaling relationships yield a lower NOx production potential for fuel-side dilution due to its smaller flame size, whereas air dilution yields a larger air entrainment requirement and a subsequently larger flame, with longer residence times and higher thermal NOx generation. For more complex staged-air LDI combustor designs, the dilution of the primary combustion air at fuel-rich conditions can result in the full utilization of the diluent for reducing the peak flame temperature, while also controlling flame volume and residence time for NOx reduction purposes. However, differential diffusion of hydrogen out of a diluted hydrogen/nitrogen fuel jet can create regions of higher hydrogen content in the immediate vicinity of the fuel injection point than can be attained with the dilution of the air stream, leading to increased flame stability. By this mechanism, fuel-side dilution extends the operating envelope to areas with higher velocities in the experimental configurations tested, where faster mixing rates further reduce flame residence times and NOx emissions. Strategies for accurate computational modeling of LDI combustors' stability characteristics are also discussed. JF - Journal of Engineering for Gas Turbines and Power.

15122152 AB - In recent years, various models have been developed for describing the reaction mechanisms in solid oxide fuel cell (SOFC) especially for the cathode electrode. However, many fundamental issues regarding the transport of oxygen and electrode kinetics have not been fully understood. This review tried to summarize the present status of the SOFC cathode modeling efforts, and associated experimental approaches on this topic. In addition, unsolved problems and possible future research directions for SOFC cathode kinetics had been discussed.

Experimental results showed significant improvements to carbon monoxide (CO) conversions and production of hydrogen (H sub(2)) when CO sub(2) sorbents are incorporated into the water gas shift reaction. Results suggested that the performance of the sorbent is linked to the presence of a Ca(OH) sub(2) phase within the sorbent. Promoting calcium oxide (CaO) sorbents with sodium hydroxide (NaOH) as well as pre-treating the CaO sorbent with steam appeared to lead to formation of Ca(OH) sub(2), which improved CO sub(2) sorption capacity and WGS performance. Results suggest that an optimum amount of NaOH exists as too much leads to a lower capture capacity of the resultant sorbent. During capture, the NaOH-promoted sorbents displayed a high capture efficiency (nearly 100%) at temperatures of 300-600 degree C. Results also suggest that the CaO sorbents possess catalytic properties which may augment the WGS reactivity even post-breakthrough. Furthermore, promotion of CaO by NaOH significantly reduces the regeneration temperature of the former.

However, the presence of trace contaminants, i.e., sulfur dioxide and nitric oxides, will impact the electrolyte within the cell. If a lower temperature cell could be devised that would utilize the benefits of commercially-available, upstream desulfurization and denitrification in the power plant, then this CO sub(2) separation technique can approach more viability in the carbon sequestration area. Recent work has led to the assembly and successful operation of a low temperature electrochemical cell. In the proof-of-concept testing with this cell, an anion exchange membrane was sandwiched between gas-diffusion electrodes consisting of nickel-based anode electrocatalysts on carbon paper. When a potential was applied across the cell and a mixture of oxygen and carbon dioxide was flowed over the wetted electrolyte on the cathode side, a stream of CO sub(2) to O sub(2) was produced on the anode side, suggesting that carbonate/bicarbonate ions are the CO sub(2) carrier in the membrane. Since a mixture of CO sub(2) and O sub(2) is produced, the possibility exists to use this stream in oxy-firing of additional fuel. From this research, a novel concept for efficiently producing a carbon dioxide rich effluent from combustion of a fossil fuel was proposed. Carbon dioxide and oxygen are captured from the flue gas of a fossil-fuel combustor by one or more electrochemical cells or cell stacks. The separated stream is then transferred to an oxy-fired combustor which uses the gas stream for ancillary combustion, ultimately resulting in an effluent rich in carbon dioxide.

These catalysts were compared to bulk, unsupported BNHA; 3 wt% Ni/alumina; and 3 wt% Ni/GDC (the latter two prepared by conventional impregnation) for the partial oxidation (POX) of n-tetradecane. The reaction studies included examining the effect of 50 ppm S as dibenzothiophene (DBT) and 5 wt% 1-methylnaphthalene (MN) on the product yield under POX conditions. Temperature programmed oxidation (TPO) was used to characterize carbon formation in the reactor. The materials were characterized by BET, ICP-OES, XRD, and SEM/EDS prior to the reaction tests. Characterization of the two GDC-supported BNHA catalysts prior to the reaction studies indicated no significant differences in the bulk composition, surface area, and crystal structure. However, SEM images showed a larger amount of exposed GDC support surface area for the material prepared by IWI. Both of the GDC-supported BNHA materials demonstrated greatly reduced deactivation, with significantly reduced carbon formation compared to bulk BNHA. This was attributed to the oxygen-conducting property of the GDC, which reduced the rate of deactivation of the reaction sites by DBT and MN. The material prepared by IWI demonstrated more stable hydrogen and carbon monoxide yield than the material prepared by SSM. Although both catalysts deactivated in the presence of DBT and MN, the activity of the catalyst prepared by IWI recovered activity more quickly after the contaminants were removed. This material also maintained >50% of its initial hydrogen yield for more than 4 h after exposure to DBT and MN, while the hydrogen for the material prepared by SSM dropped to this same level within 2 h. Incipient wetness impregnation appears to provide a higher degree of interaction between the oxygen-conducting GDC support and the hexaaluminate, resulting in less rapid deactivation, which appears to be due primarily to carbon deposition.

The interactions of mercury and arsenic with Pd/Al sub(2)O sub(3) model thin film sorbents and Pd/Al sub(2)O sub(3) powders have been studied to determine the relative affinities of palladium for mercury and arsenic, and how they are affected by temperature and the presence of hydrogen sulfide in the fuel gas. The implications of the results on strategies for capturing the toxic metals using a sorbent bed are discussed.

2012-016342 AB - A controlled release of CO (sub 2) was conducted at a field site in Bozeman, Montana, USA in July of 2008 in a multi-laboratory study of near surface transport and detection technologies. The development of a subsurface CO (sub 2) plume near the middle packer section of the horizontal release was studied using soil-gas and surface flux measurements of CO (sub 2) . A perfluorocarbon tracer was added to the CO (sub 2) released from this section of the horizontal well, and the development of atmospheric plumes of the tracer was studied under various meteorological conditions using horizontal and vertical grids of monitors containing sorbent material to collect the tracer. This study demonstrated the feasibility of using remote sensing for the ultra low level detection of atmospheric plumes of tracers as means to monitor the near surface leakage of sequestered CO (sub 2) .

A slotted horizontal well divided into six zones was installed in the shallow subsurface. The scale and CO (sub 2) release rates were chosen to be relevant to developing monitoring strategies for geological carbon storage. The field site was characterized before injection, and CO (sub 2) transport and concentrations in saturated soil and the vadose zone were modeled. Controlled releases of CO (sub 2) from the horizontal well were performed in the summers of 2007 and 2008, and collaborators from six national labs, three universities, and the U.S. Geological Survey investigated movement of CO (sub 2) through the soil, water, plants, and air with a wide range of near surface detection techniques. An overview of these results will be presented.

However, carbon dioxide buoyancy may lead to its migration away from a storage site and into the shallow subsurface and atmosphere if permeable pathways (such as well bores, fractures, or faults) are present. Subsurface pressure changes due to carbon dioxide injection may also cause brines to migrate out of storage formations and into other hydrologic units. The protection of groundwater quality, along with the development of groundwater-specific monitoring and mitigation tools, is necessary for the implementation of successful carbon dioxide storage. Previous work in our laboratory has shown that gel-immobilized redox- and pH-sensitive mineral species can be used to evaluate geochemical conditions in sediment porewaters and in the waters of flooded bituminous coal mines. In this study, we used the geochemical model MINTEQA2 to evaluate a wide variety of potential indicator compounds that would be expected to demonstrate increased solubility in groundwater upon the addition of carbon dioxide. The most promising of these compounds included a wide variety of metal oxides and carbonates. These were prepared and tested under controlled laboratory conditions simulating carbon dioxide-impacted brine and groundwater. A prototype field sensor based on the spectrophotometric analysis of gel-immobilized compounds in a multiwell plate format is presented.

The formation underlies nearly 50,000 square miles of land and may contain more than 400 trillion cubic feet of recoverable natural gas. Recent advances in directional drilling and reservoir stimulation technology have made the Marcellus Shale an attractive exploration target. The Marcellus is a Middle Devonian age, organic-rich black shale. Hydraulic fracturing is required to produce economical quantities of gas from such a fine-grained rock. Water or other liquids under high pressure are used to create fractures in the Marcellus Shale. These hydraulic fractures often intersect pre-existing natural fractures, providing a network of permeable flowpaths for natural gas transport to a well. Directional drilling that penetrates long horizontal distances through the shale allows multiple stages of vertical hydraulic fractures to be generated from the lateral borehole, creating permeable pathways into a very large volume of rock. Several million gallons of water are needed to hydraulically fracture a typical horizontal Marcellus Shale well. Obtaining the required volume of water resources, and transporting these to often remote, rural well sites can have significant environmental impacts. Fluids recovered from the well after the treatment must be handled and disposed of properly. These fluids commonly contain a mix of the proprietary chemicals used for the fracturing, plus any produced formation brines. The formation brines often have high TDS, including sodium, chloride, barium, strontium, and other metals, plus unknown organic constituents and radionuclides that may exceed drinking-water standards. Although natural gas as a fuel generally has less of an environmental impact than other fossil hydrocarbons, large-scale production of gas from the Marcellus Shale may affect watersheds, water supplies, and require the disposal of large quantities of potentially contaminated fluids. Investigations focused on improving the predictability of the shale gas resource, along with a better understanding of the geochemistry and evolution of formation brines may help resolve these environmental concerns.

The possibility of more stringent environmental regulations for greenhouse gas emissions in the utility sector has provided a window of opportunity for integrated gasification combined cycles (IGCCs) equipped with carbon capture and sequestration (CCS) to participate significantly in this expansion. This paper analyzes several advanced technologies under development in the Department of Energy (DOE) research and development (R&D) portfolio that have the potential to improve process efficiency, reduce capital and operating expense, and increase plant availability resulting in a significant reduction in the cost of electricity for plants that capture carbon.

A technical challenge surrounding the geologic sequestration of CO (sub 2) is tracking the movement of the fluids pumped underground. Monitoring, verification, and accounting activities related to CO (sub 2) storage are important for assuring that any sequestered CO (sub 2) does not escape to the surface and can be considerably aided by reflection seismic-based detection methods. Through the use of lab-scale velocity measurements under in-situ conditions, combined with multiple 3D reflection seismic surveys, we hope to effectively track the movements of CO (sub 2) after injection.

LOUIS COUNTIES, MINNESOTA. [Part 10 of 14] T2 - MESABA ENERGY PROJECT, TACONITE TAX RELIEF AREA, ITASCA AND ST. LOUIS COUNTIES, MINNESOTA. AN - 756826894; 14097-090393_0010 AB - PURPOSE: The granting of funds for the construction of a coal-based integrated gasification combined cycle (IGCC) electric power plant demonstration project to be located in the Taconite Tax Relief Area (TTRA) of Itasca and St. Louis counties, Minnesota is proposed. The TTRA encompasses 13,000 square miles in northeastern Minnesota from Crosby to the north shore of Lake Superior. Excelsior Energy Inc. would design, construct, and operate the Mesaba Energy Project in two phases; each phase would nominally generate 600 megawatts (MW) of electricity for export to the electrical grid, for a total output of 1,200 MW at full buildout. IGCC meets the goals of the Clean Coal Power Initiative (CCPI) Program by utilizing an estimated 240-year domestic supply of reliable, low-cost coal in an environmentally acceptable manner. The project would demonstrate advanced IGCC technologies to produce electricity, including advanced gasification and air separation systems, feedstock flexibility, improved environmental performance characteristics, and improved thermal efficiency. The technologies would be more efficient, economical, reliable, and environmentally favorable than conventional coal-fueled steam electric generation plants. After a one-year demonstration period, if economically feasible, the Mesaba IGCC power plant could be operated commercially for a period of 20 years or longer. Mesaba would employ IGCC technology, using Conoco-Phillips E-Gas technology. Gasification is the process of converting coal, petroleum coke, or blends of these feedstocks to a gaseous fuel called synthesis gas. A combined-cycle electric power plant uses both a steam turbine generator and a combustion generator at one location to generate electricity. Combining the gasification process with the combined-cycle power plant is known as IGCC, which is an inherently lower-polluting and more energy-efficient technology for producing electricity from solid feedstocks. Coal would be delivered to the site by a subsidiary of CN Railway. Electricity would be transmitted to the regional grid by power lines constructed within the TTRA. The Department of Energy (DOE) would provide $36 million in co-funding, through a cooperative agreement with Excelsior under the CCPI Program for the design and one-year first-phase operational demonstration testing period. The DOE may also provide a loan guarantee to Excelsior pursuant to the Energy Policy Act of 2005 to guarantee a portion of the private sector financing of the project; however, this potential loan guarantee is not part of DOE's proposed action. The cost of the first phase is estimated at $2.16 billion. In addition to the proposed action, this final EIS considers a No Action Alternative and alternative sites for the demonstration project. POSITIVE IMPACTS: The proposed power plant would demonstrate the commercial readiness of the Conoco-Philips E-Gas gasification technology in a fully integrated and quintessential IGCC utility-scale application. Such a demonstration would accelerate the commercialization of clean coal technologies capable of achieving substantial efficiencies, environmental performance, and cost-competitiveness. NEGATIVE IMPACTS: The plant footprint would occupy 192 acres, which would be cleared of vegetation and the associated wildlife habitat. Site grading and preparation would require 2.97 million cubic yards of cut land and 1.75 million cubic yards of fill. Natural gas pipeline rights-of-way would displace 142 to 171 acres of prime farmland, and transmission line rights-of-way would disturb up to 151 acres of prime farmland. The power plant site and related transmission and pipeline facilities would lie within the Western Mesabi Iron Range Early Mining Landscape District and several individual historic sites would be directly affected.

AN - 756826840; 14097-090393_0002 AB - PURPOSE: The granting of funds for the construction of a coal-based integrated gasification combined cycle (IGCC) electric power plant demonstration project to be located in the Taconite Tax Relief Area (TTRA) of Itasca and St. Louis counties, Minnesota is proposed. The TTRA encompasses 13,000 square miles in northeastern Minnesota from Crosby to the north shore of Lake Superior. Excelsior Energy Inc. would design, construct, and operate the Mesaba Energy Project in two phases; each phase would nominally generate 600 megawatts (MW) of electricity for export to the electrical grid, for a total output of 1,200 MW at full buildout. IGCC meets the goals of the Clean Coal Power Initiative (CCPI) Program by utilizing an estimated 240-year domestic supply of reliable, low-cost coal in an environmentally acceptable manner. The project would demonstrate advanced IGCC technologies to produce electricity, including advanced gasification and air separation systems, feedstock flexibility, improved environmental performance characteristics, and improved thermal efficiency. The technologies would be more efficient, economical, reliable, and environmentally favorable than conventional coal-fueled steam electric generation plants. After a one-year demonstration period, if economically feasible, the Mesaba IGCC power plant could be operated commercially for a period of 20 years or longer. Mesaba would employ IGCC technology, using Conoco-Phillips E-Gas technology. Gasification is the process of converting coal, petroleum coke, or blends of these feedstocks to a gaseous fuel called synthesis gas. A combined-cycle electric power plant uses both a steam turbine generator and a combustion generator at one location to generate electricity. Combining the gasification process with the combined-cycle power plant is known as IGCC, which is an inherently lower-polluting and more energy-efficient technology for producing electricity from solid feedstocks. Coal would be delivered to the site by a subsidiary of CN Railway. Electricity would be transmitted to the regional grid by power lines constructed within the TTRA. The Department of Energy (DOE) would provide $36 million in co-funding, through a cooperative agreement with Excelsior under the CCPI Program for the design and one-year first-phase operational demonstration testing period. The DOE may also provide a loan guarantee to Excelsior pursuant to the Energy Policy Act of 2005 to guarantee a portion of the private sector financing of the project; however, this potential loan guarantee is not part of DOE's proposed action. The cost of the first phase is estimated at $2.16 billion. In addition to the proposed action, this final EIS considers a No Action Alternative and alternative sites for the demonstration project. POSITIVE IMPACTS: The proposed power plant would demonstrate the commercial readiness of the Conoco-Philips E-Gas gasification technology in a fully integrated and quintessential IGCC utility-scale application. Such a demonstration would accelerate the commercialization of clean coal technologies capable of achieving substantial efficiencies, environmental performance, and cost-competitiveness. NEGATIVE IMPACTS: The plant footprint would occupy 192 acres, which would be cleared of vegetation and the associated wildlife habitat. Site grading and preparation would require 2.97 million cubic yards of cut land and 1.75 million cubic yards of fill. Natural gas pipeline rights-of-way would displace 142 to 171 acres of prime farmland, and transmission line rights-of-way would disturb up to 151 acres of prime farmland. The power plant site and related transmission and pipeline facilities would lie within the Western Mesabi Iron Range Early Mining Landscape District and several individual historic sites would be directly affected.

AN - 756826814; 14097-090393_0008 AB - PURPOSE: The granting of funds for the construction of a coal-based integrated gasification combined cycle (IGCC) electric power plant demonstration project to be located in the Taconite Tax Relief Area (TTRA) of Itasca and St. Louis counties, Minnesota is proposed. The TTRA encompasses 13,000 square miles in northeastern Minnesota from Crosby to the north shore of Lake Superior. Excelsior Energy Inc. would design, construct, and operate the Mesaba Energy Project in two phases; each phase would nominally generate 600 megawatts (MW) of electricity for export to the electrical grid, for a total output of 1,200 MW at full buildout. IGCC meets the goals of the Clean Coal Power Initiative (CCPI) Program by utilizing an estimated 240-year domestic supply of reliable, low-cost coal in an environmentally acceptable manner. The project would demonstrate advanced IGCC technologies to produce electricity, including advanced gasification and air separation systems, feedstock flexibility, improved environmental performance characteristics, and improved thermal efficiency. The technologies would be more efficient, economical, reliable, and environmentally favorable than conventional coal-fueled steam electric generation plants. After a one-year demonstration period, if economically feasible, the Mesaba IGCC power plant could be operated commercially for a period of 20 years or longer. Mesaba would employ IGCC technology, using Conoco-Phillips E-Gas technology. Gasification is the process of converting coal, petroleum coke, or blends of these feedstocks to a gaseous fuel called synthesis gas. A combined-cycle electric power plant uses both a steam turbine generator and a combustion generator at one location to generate electricity. Combining the gasification process with the combined-cycle power plant is known as IGCC, which is an inherently lower-polluting and more energy-efficient technology for producing electricity from solid feedstocks. Coal would be delivered to the site by a subsidiary of CN Railway. Electricity would be transmitted to the regional grid by power lines constructed within the TTRA. The Department of Energy (DOE) would provide $36 million in co-funding, through a cooperative agreement with Excelsior under the CCPI Program for the design and one-year first-phase operational demonstration testing period. The DOE may also provide a loan guarantee to Excelsior pursuant to the Energy Policy Act of 2005 to guarantee a portion of the private sector financing of the project; however, this potential loan guarantee is not part of DOE's proposed action. The cost of the first phase is estimated at $2.16 billion. In addition to the proposed action, this final EIS considers a No Action Alternative and alternative sites for the demonstration project. POSITIVE IMPACTS: The proposed power plant would demonstrate the commercial readiness of the Conoco-Philips E-Gas gasification technology in a fully integrated and quintessential IGCC utility-scale application. Such a demonstration would accelerate the commercialization of clean coal technologies capable of achieving substantial efficiencies, environmental performance, and cost-competitiveness. NEGATIVE IMPACTS: The plant footprint would occupy 192 acres, which would be cleared of vegetation and the associated wildlife habitat. Site grading and preparation would require 2.97 million cubic yards of cut land and 1.75 million cubic yards of fill. Natural gas pipeline rights-of-way would displace 142 to 171 acres of prime farmland, and transmission line rights-of-way would disturb up to 151 acres of prime farmland. The power plant site and related transmission and pipeline facilities would lie within the Western Mesabi Iron Range Early Mining Landscape District and several individual historic sites would be directly affected.

[Part 3 of 14] T2 - MESABA ENERGY PROJECT, TACONITE TAX RELIEF AREA, ITASCA AND ST. LOUIS COUNTIES, MINNESOTA. AN - 756826553; 14097-090393_0003 AB - PURPOSE: The granting of funds for the construction of a coal-based integrated gasification combined cycle (IGCC) electric power plant demonstration project to be located in the Taconite Tax Relief Area (TTRA) of Itasca and St. Louis counties, Minnesota is proposed. The TTRA encompasses 13,000 square miles in northeastern Minnesota from Crosby to the north shore of Lake Superior. Excelsior Energy Inc. would design, construct, and operate the Mesaba Energy Project in two phases; each phase would nominally generate 600 megawatts (MW) of electricity for export to the electrical grid, for a total output of 1,200 MW at full buildout. IGCC meets the goals of the Clean Coal Power Initiative (CCPI) Program by utilizing an estimated 240-year domestic supply of reliable, low-cost coal in an environmentally acceptable manner. The project would demonstrate advanced IGCC technologies to produce electricity, including advanced gasification and air separation systems, feedstock flexibility, improved environmental performance characteristics, and improved thermal efficiency. The technologies would be more efficient, economical, reliable, and environmentally favorable than conventional coal-fueled steam electric generation plants. After a one-year demonstration period, if economically feasible, the Mesaba IGCC power plant could be operated commercially for a period of 20 years or longer. Mesaba would employ IGCC technology, using Conoco-Phillips E-Gas technology. Gasification is the process of converting coal, petroleum coke, or blends of these feedstocks to a gaseous fuel called synthesis gas. A combined-cycle electric power plant uses both a steam turbine generator and a combustion generator at one location to generate electricity. Combining the gasification process with the combined-cycle power plant is known as IGCC, which is an inherently lower-polluting and more energy-efficient technology for producing electricity from solid feedstocks. Coal would be delivered to the site by a subsidiary of CN Railway. Electricity would be transmitted to the regional grid by power lines constructed within the TTRA. The Department of Energy (DOE) would provide $36 million in co-funding, through a cooperative agreement with Excelsior under the CCPI Program for the design and one-year first-phase operational demonstration testing period. The DOE may also provide a loan guarantee to Excelsior pursuant to the Energy Policy Act of 2005 to guarantee a portion of the private sector financing of the project; however, this potential loan guarantee is not part of DOE's proposed action. The cost of the first phase is estimated at $2.16 billion. In addition to the proposed action, this final EIS considers a No Action Alternative and alternative sites for the demonstration project. POSITIVE IMPACTS: The proposed power plant would demonstrate the commercial readiness of the Conoco-Philips E-Gas gasification technology in a fully integrated and quintessential IGCC utility-scale application. Such a demonstration would accelerate the commercialization of clean coal technologies capable of achieving substantial efficiencies, environmental performance, and cost-competitiveness. NEGATIVE IMPACTS: The plant footprint would occupy 192 acres, which would be cleared of vegetation and the associated wildlife habitat. Site grading and preparation would require 2.97 million cubic yards of cut land and 1.75 million cubic yards of fill. Natural gas pipeline rights-of-way would displace 142 to 171 acres of prime farmland, and transmission line rights-of-way would disturb up to 151 acres of prime farmland. The power plant site and related transmission and pipeline facilities would lie within the Western Mesabi Iron Range Early Mining Landscape District and several individual historic sites would be directly affected.

13403409 AB - The U.S. Department of Energy's National Energy Technology Laboratory, under the Office of Fossil Energy's Innovations for Existing Plants Program, carried out a comprehensive Hg research and development program for coal-fired power generation facilities since the mid-1990s. Working collaboratively with the U.S. Environmental Protection Agency, the Electric Power Research Institute, power plant operators, state and local agencies, and a host of research organizations and academic institutions, the Program identified the major factors that affect mercury speciation and capture in coal combustion flue gas and funneled this knowledge into the development of a suite of mercury control technologies for the diverse fleet of U.S. coal-fired power plants. The high performance observed during full-scale field testing has given coal-fired power plant operators the confidence to begin deploying technology. As of March 2009, more than 130 full-scale activated carbon injection systems have been ordered by the U.S. coal-fired power generators. These contracts include both new and retrofit installations and represent over 55 GW of coal-based electric generating capacity.

2011-057669 AB - The Marcellus Shale occurs in the Appalachian Basin of the Eastern United States in New York, Pennsylvania, West Virginia, western Maryland, and eastern Ohio. This shale contains significant natural gas resources; published estimates suggest that up to 363 trillion cubic feet (TCF) of gas ultimately may be recoverable. Recent advances in drilling technology, combined with higher wellhead prices have made the Marcellus Shale an attractive exploration target. The Marcellus Shale was deposited as an organic-rich mud across the Appalachian Basin in the Middle Devonian. The production of commercial quantities of gas from such a fine-grained rock requires the creation of high permeability flowpaths within the formation to allow the gas to flow to a well. In the Marcellus, this is generally done by hydraulic fracturing, where water or other liquids under high pressure are used to create fractures in the rock. Along with pre-existing natural fractures, the hydraulic fractures act to provide a network of flowpaths for transporting gas to a well. Using directional drilling to penetrate long horizontal distances through the shale allows a series of hydraulic fractures to be generated from the horizontal borehole, contacting a very large volume of rock. Several million gallons of water are required to drill and hydraulically fracture a typical horizontal Marcellus Shale gas well. Flowback fluids recovered from these wells, including the proprietary liquids used for the fracturing and any produced formation brines, must be handled and disposed of properly. The formation brines may contain high concentrations of sodium, chloride, bromide, and other inorganic constituents, such as arsenic, barium, various heavy metals, and radionuclides that significantly exceed drinking-water standards. Large-scale production of gas from the Marcellus Shale may impact local water supplies, and also result in large quantities of potentially contaminated fluids that require disposal. New and ongoing investigations focused on improving the predictability of the gas resource, along with a better understanding of the geochemistry and evolution of formation brines may help to resolve these water resource concerns.

These studies were intended to identify potential leakage pathways for injected CO (sub 2) due to degradation of the well bore. Two distinct test series were conducted on core samples of the Mt. Simon sandstone from the Illinois Basin, IL, and the Grand Ronde basalt from the Pasco Basin, WA. LaFarge Class H well bore cement was used for both series. Reservoir rock/cement cores were immersed within a CO (sub 2) -saturated brine for up to 2000 hours at 35 degrees C and 100 atm CO (sub 2) . Results suggest that the impact of SCCO (sub 2) injection is reservoir-specific, being highly dependent on the reservoir brine and rock type. Brine pH can be significantly altered by CO (sub 2) injection, which in turn can dramatically impact the dissolution characteristics of the reservoir rock. Finally, well bore cement alteration was identified, particularly for fresh cast cement allowed to cure at SCCO (sub 2) conditions. However, this alteration was generally limited to an outer rind of carbonate and Ca-depleted cement which appeared to protect the majority of the cement core from further attack. These studies indicate that at the cement-rock interface, the annular space may be filled by carbonate which could act as an effective barrier against further CO (sub 2) migration along the well bore.

These amines were immobilized within polystyrene (PS)-, silicon dioxide (SiO2)-, or polymethylmethacrylate (PMMA)-based substrates at various weight ratios. Testing was conducted in various reactor systems, where the reactive water required for the capture of carbon dioxide (CO2) was tracked during the adsorption/desorption cycles by mass spectrometer gas analysis. The water management for these sorbents was quantified and used to assess the technical feasibility of the operating conditions for the capture of CO2 from simulated flue gas streams. In addition, the heats of reaction and performance capture loading capacities of these sorbents were also determined by differential scanning calorimetry (DSC) and thermogravimetric analyses (TGAs), respectively, in both dry and humidified CO2 gas streams. The regenerable solid amine sorbents investigated in this study exhibit acceptable CO2-capture loading capacities of 2.5-3.5 mol of CO2/kg of sorbent by TGA and a laboratory-scale fixed-bed reactor. These sorbents were stable over the adsorption/desorption temperature range of 25-105 C for 10 cyclic tests. According to the DSC analysis, the heat of reaction generated by these sorbents was in the range of 400-600 Btu/lb. CO2, which will require a reactor with heat management capabilities.

The gas hydrate occurs within very fine grained, immature volcaniclastic sands of the Oligocene Frio sand. Analysis of well data acquired from the Alaminos Canyon Block 818 #1 ("Tigershark") well shows a total gas hydrate occurrence 13 m thick, with inferred gas hydrate saturation as high as 80% of sediment pore space. Average porosity in the reservoir is estimated from log data at approximately 42%. Permeability in the absence of gas hydrates, as revealed from the analysis of core samples retrieved from the well, ranges from 600 to 1500 millidarcies. The 3-D seismic data reveals a strong reflector consistent with significant increase in acoustic velocities that correlates with the top of the gas-hydrate-bearing sand. This reflector extends across an area of approximately 0.8 km (super 2) and delineates the minimal probable extent of the gas hydrate accumulation. The base of the inferred gas-hydrate zone also correlates well with a very strong seismic reflector that indicates transition into units of significantly reduced acoustic velocity. Seismic inversion analyses indicate uniformly high gas-hydrate saturations throughout the region where the Frio sand exists within the gas hydrate stability zone. Numerical modeling of the potential production of natural gas from the interpreted accumulation indicates serious challenges for depressurization-based production in settings with strong potential pressure support from extensive underlying aquifers.

The resulting ash composition distribution, by particle size and density, of ground Pittsburgh Seam coal was determined. The thermodynamically stable phases were calculated for each particle classification for a range of temperatures, with attention paid to the form of the non-slag phases, which must dissolve in the slag layer on the gasifier wall. Undissolved particles can be carried with the gas, resulting in fouling of downstream components. Results are separated into a comparison of the liquid versus solid phases formed, and a comparison of the phases formed for each particle type. Certain particle compositions form stable crystalline oxide phases that are usually incorporated into the slag at higher temperatures, while others can form metallic iron, which is stable even at high temperatures.

A series of tests were conducted to investigate a novel reaction concept designed to achieve neutralization of mixtures of acidic oil field produced brine and caustic industrial byproducts while sequestering substantial quantities of anthropogenic carbon dioxide (CO(2)) in a mixed-flow reactor. Experiments were conducted to determine the CO(2)-bearing capacity of reactive mixtures of brine from the Oriskany Sandstone Formation with three caustic industrial byproducts: flue gas desulfurization (FGD) spray dryer ash, Class C fly ash subbituminous coal combustion byproduct, and bauxite residue slurry from the alumina production process. Reactions were conducted in a closed, well-mixed (1,500 rpm) reactor with gas composed of 29.46% vol./vol. CO(2) balanced by nitrogen gas (N(2)) fed at a rate of 300mL/min. Reactions were carried out at ambient conditions. Results show linear relationships between caustic byproduct addition and CO(2)-bearing capacity, with relatively small impact of brine addition as compared to deionized water addition. FGD spray dryer ash/brine mixtures exhibited higher CO(2) reactivity than those using Class C fly ash (0.759 moles CO(2) at 23.6% solids by weight and 0.036 moles CO(2) at 23.3% solids by weight, respectively). Bauxite residue exhibited moderate capacities in mixtures with higher percent solids (0.335 moles CO(2) in 40% solids bauxite residue slurry). Carbonation capacity of caustic byproduct/ acidic brine mixtures was shown to increase linearly with respect to percent caustic byproduct addition, but enhanced mineral carbonate precipitation resulting from synergistic reaction of brine cations with increased dissolved carbonate species was not observed in the short term.

The release of metals from the nine samples of residues generated in three coal integrated gasification combined cycle (IGCC) installations was determined. Cations tended to be more soluble than from PC fly ash samples. Except for Hg, total cation solubility was due to the relatively high concentration in a few leachate samples. For several IGCC by-product samples generated from a mixture of coal and pet coke, the amount of As, Ni, and Zn extracted from the IGCC residues exceeded primary or secondary drinking water standards in the early leachate samples.

Following saturation of the material's immobilized tertiary amines, CA-bearing carrier water is separated and recycled to the absorption stage while CO sub(2)-loaded material is thermally regenerated. Process application of this concept would involve operation of two or more columns in parallel with thermal regeneration with low-pressure steam taking place after the capacity of a column of amine-bearing polymeric material was exceeded. PABB CO sub(2)-bearing capacity was evaluated by thermogravimetric analysis (TGA) for beads of three acrylamido buffering monomer ingredient concentrations: 0 mol/kg bead, 0.857 mol/kg bead, and 2 mol/kg bead. TGA results demonstrate that CO sub(2)-bearing capacity increases with increasing PABB buffering concentration and that up to 78% of the theoretical CO sub(2)-bearing capacity was realized in prepared PABB samples (0.857 mol/kg recipe). The highest observed CO sub(2)-bearing capacity of PABB was 1.37 mol of CO sub(2) per kg dry bead. TGA was also used to assess the regenerability of CO sub(2)-loaded PABB. Preliminary results suggest that CO sub(2) is partially driven from PABB samples at temperatures as low as 55 C, with complete regeneration occurring at 100 C. Other physical characteristics of PABB are discussed. In addition, the effectiveness of bovine carbonic anhydrase for the catalysis of CO sub(2) dissolution is evaluated. Potential benefits and drawbacks of the proposed process are discussed.

There are three options for capturing CO2 from point sources: post-combustion capture, pre-combustion capture, and oxy-combustion. Several processes are available to capture CO2, and new or improved processes are under development. However, CO2 capture is the most expensive part of CCS, typically accounting for 75% of overall cost. CCS will benefit significantly from the development of a lower cost post-combustion CO2 capture process that can be retrofitted to existing power plants. Once captured, the CO2 is compressed to about 150 atm and pipelined at supercritical conditions to a suitable storage site. Oil and gas reservoirs, because they have assured seals and are well characterized, are promising early opportunity sites. Saline formations are much more extensive and have a huge potential storage capacity, but are much less characterized. Several commercial and a number of pilot CCS projects are underway around the world. Information from these projects will form the basis for the development of CCS as a climate change mitigation strategy. These projects are contributing to the development of suitable regulations, determining best operating practices, improving mathematical models, and providing information to the public and other stakeholders. Based on current knowledge, CCS appears to be a promising option for reducing GHG emissions.

Electroplating of metals or alloys followed by oxidation offers a cost-effective method. In this study, pure Co and Mn/Co alloys formed by electrodeposition are used to protect the substrate, SUS 430. On-cell tests, using uncoated, cobalt-coated and MnCo-coated interconnects were conducted at 375 mA cm super(-2) for 323, 500 and 820 h, respectively. The results show that cell power degrades at a rate of 33% in 320 h using an uncoated interconnect. Significant improvements are obtained for cell tests utilizing unoptimized coated interconnects with the degradation rate of 5% and 9% per 1000 h for cobalt and MnCo coatings, respectively. Based on the results from SEM and XRD studies, the advantages of both coatings are to successfully inhibit Cr diffusion to the scale surface. However, thin ([not, vert, similar]2 mu m) cobalt coating allows fast scale growth, while thicker cobalt coatings have the potential to fail due to mismatch in the coefficient of temperature expansion (CTE) between Co sub(3)O sub(4) and the SUS 430 substrate. In spite of higher degradation rate for the MnCo coatings evaluated here, the addition of Mn into the cobalt coating not only aids in suppression of scale growth, but also reduces the CTE mismatch. Furthermore, no performance decay after two thermal cycles was observed. Finally, the cell degradation was observed to have a correlation with the cell cathode interlayer microstructure.

Each method was tested in triplicate, according to the published procedure, and leachate was analyzed for 23 elements. The procedures were compared on the basis of elemental availability, defined as the cumulative elemental release per kg of sample, and the variation in extraction with increased L/S as a surrogate for long term release. Higher availability values were obtained with the SBLP and MWLP, which cover a range of pH's and 3TIER, which uses EDTA to form soluble complexes. SGLP, a high pH procedure, and TCLP, mildly acidic, generally produced lower availability values. Cumulative elemental extraction as a function of L/S in SBLP, MWLP and 3TIER generally agreed within an order of magnitude.

Samples of fly ash, FGD gypsum, and wallboard made from FGD gypsum were tested under both dark and illuminated conditions with or without the addition of water to the sample. Mercury releases varied widely, with 7-day experiment averages ranging from -6.8 to 73 ng/m2 h for the fly ash samples and -5.2 to 335 ng/m2 h for the FGD/wallboard samples. Initial mercury content, fly ash type, and light exposure had no observable consistent effects on the mercury flux. For the fly ash samples, the effect of a mercury control technology was to decrease the emission. For three of the four pairs of FGD gypsum and wallboard samples, the wallboard sample released less (or absorbed more) mercury than the gypsum.

The differences in texture and porosity between coal powder and lumps may affect the transport and interaction of fluids and coal. In this work, the information about the coal texture and micro- and meso-porosity was obtained via the BET, BJH, and Dubinin-Astakhov analyses. We further investigated the free-fluid-phase volume (free-volume) effects due to helium interaction with the powder and the lumps. During the manometric experiment, helium penetration into the dry coal matrix resulted in slow relaxation of pressure. After exposure of coal to helium, there have been no significant changes of the macroscopic dimensions observed and the relaxation process can be attributed to microscopic "free-volume" effects. Evolution of the sorption-desorption rates indicates that exposure to helium may change the texture and apparent (helium) density of dry coal.

We formed methane hydrate in three different kinds of silica sand (Korean sand, F110 sand, and a mixture of F110 sand and fine silt). Hydrate formation and phase saturation were monitored using temperature and pressure measurements as well as x-ray computed tomography (CT). The van Genuchten model relative permeability parameter, m, (van Genuchten, 1980) was estimated using differential pressure (Delta P) across the sand column under steady state flow and average hydrate saturation measured with CT images. We compared the estimated parameters in terms of hydrate saturations (20-35%) and sand types. Further estimations of the relative permeability parameter are underway using numerical inversion of transient CT measured water saturation data and independently measured capillary pressure.

The U.S. Department of Energy's National Energy Technology Laboratory has utilized multi-frequency airborne, ground electromagnetic, ground resistivity, and borehole methods to characterize the near-surface hydrogeology of several areas within the PRB from 2004 through 2008. Results from the geophysical surveys demonstrate the heterogeneity of the near-surface geology and hydrology of the basin. A current study in progress is characterizing hydrologic properties at a site along the Powder River designed for produced water disposal through sub-surface drip irrigation (SDI). The study integrates hydrologic and geophysical methods to characterize changes in the near-surface produced by the SDI. The geophysical data is consistent between surveys utilizing different geophysical techniques and between surveys carried out at different times. Findings suggest that the geophysical methods applied as part of this research are suitable to address a number of issues of produced water management issues for CBNG production. Among these issues are the salinity of near surface waters both in the ground water and vadose zone and the nature and distribution of clay minerals. Geophysical surveys along with surface-water and ground-water characterization and monitoring are being used to map the nature of subsurface soil and water at the SDI site. The site study began in the spring of 2007 and will continue over the proposed 5 years that the SDI system will be used for CBNG produced water disposal. Results of the study have applications in assessing impacts of CBNG-produced water utilization and disposal within the basin.

A continuously cored section targeting two potential gas hydrate bearing reservoirs was taken between 1990 to 2494 feet. Coring was initiated below the base of permafrost and extended into the gas hydrate stability zone. Total core recovered was approximately 430 feet, or 85% of the total cored interval. Geochemistry, microbiology, physical properties and other subsamples were taken during field operations along with a basic field visual description of the core. In April 2008, detailed lithostratigraphic description of the split core sections was completed. In addition, more than 500 sedimentological subsamples for select xrd/xrf, grain size, and petrographic analyses were taken. Lithostratigraphic analyses of the cores confirm that the major gas hydrate bearing reservoirs, Units "C" and "D," were comprised of individual coarsening upward, very fine to fine grained, quartz rich to quartz-feldspathic and chert-bearing sands in amalgamated, massively bedded or faintly subhorizontally laminated beds. The C and D Units each had sharp upper contacts capped by marine shales and silts which is consistent with descriptions of the marine facies in the Sagavanirktok Formation from other studies. The results of these and ongoing lithostratigraphic analyses are being integrated with the wealth of other data available from the Mount Elbert site, including wireline log measurements and results from other core analyses. Relationships between hydrate-rich, hydrate-poor, and non-hydrate bearing intervals will help refine numerical and conceptual models and improve understanding of the controls on hydrate occurrences in natural systems.

While comparable seal analysis should also play a role in geologic CO (sub 2) storage, additional questions, not part of typical hydrocarbon seal analysis, must be addressed. These include: 1) What is the impact of CO (sub 2) -rich fluids on chemical alterations of caprock minerals and sealing capacity? 2) What rate and amount of CO (sub 2) leakage would be acceptable? 3) What geomechanical impacts accompany CO (sub 2) injection? 4) Can impact on fluid flow of preexisting seal fractures and flaws be adequately characterized prior to CO (sub 2) injection? The Southwest and Southeast Regional Carbon Sequestration Partnerships, funded by the U.S. Department of Energy and managed by DOE's National Energy Technology Laboratory, are investigating these questions by studying four formations identified as potential regional seals for geologic CO (sub 2) storage: the Gothic Shale in Utah; the Kirtland Shale/Formation in New Mexico; the Tuscaloosa Marine Shale in Mississippi; and the Selma Chalk in Mississippi. For these we compare results of typical seal analysis including lithofacies interpretation, mercury injection capillary pressure measurements, rock properties, XRD mineralogy, SEM/EDX, and thin section petrology while investigating the unique questions posed by CO (sub 2) storage. The comparison emphasizes differences in geologic controls on sealing capacity for continental and marine formations. CO (sub 2) column heights are compared for each site based on capillary pressure measurements. Fracture analyses and geomechanical testing of cores yield information on seal structural properties. Numerical models of poroelastic and inelastic processes evaluate deformational trends within seals, adjacent target reservoirs, and overburden. Coupled fluid flow and geomechanical modeling address impact of fractures on multiphase fluid transport. Chemical reactivity is addressed through geochemical modeling. Through this study we identify key considerations for effective seals for long-term geologic storage of CO (sub 2) .

The objective of JIP Leg 2 is to test various exploration models for the occurrence of high-concentrations of gas hydrate within sand reservoirs in the Gulf of Mexico and to provide data to support potential future drilling and coring operations. The expedition, which will occur aboard the Helix Q4000 semi-submersible, is planned for roughly three weeks duration, and will include up to 9 exploratory holes at two or possibly three different sites in the Walker Ridge and Green Canyon areas. The logging-while-drilling program will include both 6 3/4" and 4 3/4" tools on a common bottom-hole assembly to enable collection of a full range of LWD data. This presentation will discuss the operations and initial scientific findings from the JIP Leg 2 expedition.

2011-046805 AB - Selenium found in coal utilization by-products, such as fly ash, can be released into the environment. Analysis of the species present is crucial because Se toxicity and mobility are species dependent. The leaching of Se from four fly ash samples was measured in column experiments using acetic acid, nitric acid and sodium carbonate solutions. The extractants were analyzed for total Se as well as oxyanions selenite (SeO (sub 3) (super -2) ) and selenate (SeO (sub 4) (super -2) ). Speciation was conducted using a reverse-phase column coupled to a Perkin Elmer ICP-MS with DRC system. These oxyanions have been reported as the most likely Se species associated with fly ash samples (Mattigod and Quinn, 2003). Total selenium was also analyzed using the ICP-MS. Initial results produced an increased leachability of the inorganic species with sodium carbonate compared to the other solutions. There is mass balance deficit between the total Se and the sum of the inorganic Se-species concentrations for nearly all supernants analyzed. This indicates that there is a loss of species during the extraction or speciation, or there are other species present that are not accounted for using this method such as elemental selenium or organic phases, or instrument interferences. The presence of a deficit has been reported by other researchers (EPRI, 2006) although many studies have been focused on these species alone (EPRI, 2006; NSMP, 2006). Recovery and analysis of the wash solution, extension of analysis time, and analytical adjustments will help in determining if the loss of species is due to precipitation or lack of identification.

Our findings suggest that high permeability and shallow (100-250 m) depths of these Indiana coals allowed inoculation with methanogenic microbial consortia, thus leading to widespread microbial methane generation along the eastern marginal part of the Illinois Basin. Low maturity coals in the Illinois Basin with a vitrinite reflectance R (sub o) nearly equal 0.6% contain significant amounts of coal gas ( nearly equal 3 m (super 3) /t, 96 scf/t) with > or = 97 vol.% microbial methane. The amount of coal gas can vary significantly within a coal seam both in a vertical seam section as well as laterally from location to location.

The goal was to determine the rate of reaction of hydrated cement exposed to supercritical CO2 and to CO2-saturated brine to assess the potential impact of degradation in existing wells on CO2 storage integrity. Two different forms of chemical alteration were observed. The supercritical CO2 alteration of cement was similar in process to cement in contact with atmospheric CO2 (ordinary carbonation), while alteration of cement exposed to CO2-saturated brine was typical of acid attack on cement. Extrapolation of the hydrated cement alteration rate measured for 1 year indicates a penetration depth range of 1.00 c 0.07 mm for the CO2-saturated brine and 1.68 c 0.24 mm for the supercritical CO2 after 30 years. These penetration depths are consistent with observations of field samples from an enhanced oil recovery site after 30 years of exposure to CO2-saturated brine under similar temperature and pressure conditions. These results suggest that significant degradation due to matrix diffusion of CO2 in intact Class H neat hydrated cement is unlikely on time scales of decades.

8106163 AB - Fine particulate matter (PM2.5) concentrations associated with 202 24-hr samples collected at the National Energy Technology Laboratory (NETL) paniculate matter (PM) characterization site in south Pittsburgh from October 1999 through September 2001 were used to apportion PM2.5 into primary and secondary contributions using Positive Matrix Factorization (PMF2). Input included the concentrations of PM2.5 mass determined with a Federal Reference Method (FRM) sampler, semi-volatile PM2.5 organic material, elemental carbon (EC), and trace element components of PM2.5. A total of 11 factors were identified. The results of potential source contributions function (PSCF) analysis using PMF2 factors and HYSPLIT-calculated back-trajectories were used to identify those factors associated with specific meteorological transport conditions. The 11 factors were identified as being associated with emissions from various specific regions and facilities including crustal material, gasoline combustion, diesel combustion, and three nearby sources high in trace metals. Three sources associated with transport from coalfired power plants to the southeast, a combination of point sources to the northwest, and a steel mill and associated sources to the west were identified. In addition, two secondary-material-dominated sources were identified, one was associated with secondary products of local emissions and one was dominated by secondary ammonium sulfate transported to the NETL site from the west and southwest. Of these 11 factors, the four largest contributors to PM2.5 were the secondary transported material (dominated by ammonium sulfate) (47%), local secondary material (19%), diesel combustion emissions (10%), and gasoline combustion emissions (8%). The other seven factors accounted for the remaining 16% of the PM2.5 mass. The findings are consistent with the major source of PM2.5 in the Pittsburgh area being dominated by ammonium sulfate from distant transport and so decoupled from local activity emitting organic pollutants in the metropolitan area. In contrast, the major local secondary sources are dominated by organic material.

On the other hand, deep saline reservoirs have not been as well characterized as oil and gas reservoirs. While detailed characterization of proposed sequestration sites will be necessary, it is important to assess the impact of detailed information on predictions of a site's long-term performance assessment and subsequently risk assessment. In this paper we discuss this issue through application of a systems level performance assessment model to a CO2-EOR (enhanced oil recovery) site, SACROC. SACROC is the oldest CO2-EOR field in the United States, in operation for over 35 years. As part of the U.S. Department of Energy's Regional Partnership program, a sequestration pilot test is planned at SACROC. As a part of this project characterization data such as, seismic surveys, well logs, production histories, geochemical information, and other data have been collected. The characterization data has been used to construct a geologic model of the site which will be used to predict the movement of CO2 and other fluids (such as reservoir brine) in the subsurface. The Los Alamos National Laboratory (LANL) and the National Energy Technology Laboratory (NETL) are collaborating on developing approaches to geologic CO2 sequestration risk assessment. As part of this collaboration we are applying CO2-PENS, a CO2 sequestration site performance assessment model developed by LANL, to multiple sequestration pilot tests. CO2-PENS is a coupled process-systems model that integrates field/laboratory observations with numerical models and abstractions to predict long-term performance of a geologic CO2 sequestration site. The model accounts for CO2 migration in the primary reservoir and beyond through potential leakage pathways such as wellbores, faults etc. For this work, we describe how we apply CO2-PENS to the SACROC site. We describe incorporation of potential leakage pathways in CO2-PENS, and how the probability of possible CO2 and brine leaks at the site is quantified. We discuss how results of predictions of CO2 plume migration through the geologic model described above are incorporated in CO2-PENS. Finally we demonstrate what impact a detailed geologic characterization has on the predicted CO2 migration through leakage pathways. This is done by generating geologic models with varying level of characterization data and incorporating the predicted CO2 plume migration results in CO2-PENS.

AN - 70145734; 17950875 AB - This paper reviews the Validation Phase (Phase II) of the Department of Energy's Regional Carbon Sequestration Partnerships initiative. In 2003, the U.S. Department of Energy created a nationwide network of seven Regional Carbon Sequestration Partnerships (RCSP) to help determine and implement the technology, infrastructure, and regulations most appropriate to promote carbon sequestration in different regions of the nation. The objectives of the Characterization Phase (Phase I) were to characterize the geologic and terrestrial opportunities for carbon sequestration; to identify CO(2) point sources within the territories of the individual partnerships; to assess the transportation infrastructure needed for future deployment; to evaluate CO(2) capture technologies for existing and future power plants; and to identify the most promising sequestration opportunities that would need to be validated through a series of field projects. The Characterization Phase was highly successful, with the following achievements: established a national network of companies and professionals working to support sequestration deployment; created regional and national carbon sequestration atlases for the United States and portions of Canada; evaluated available and developing technologies for the capture of CO(2) from point sources; developed an improved understanding of the permitting requirements that future sequestration activities will need to address as well as defined the gap in permitting requirements for large scale deployment of these technologies; created a raised awareness of, and support for, carbon sequestration as a greenhouse gas (GHG) mitigation option, both within industry and among the general public; identified the most promising carbon sequestration opportunities for future field tests; and established protocols for project implementation, accounting, and management. Economic evaluation was started and is continuing and will be a factor in project selection. During the Validation Phase, the seven regional partnerships will put the knowledge learned during the Characterization Phase into practice through field tests that will validate carbon sequestration technologies that are best suited to their respective regions of the country. These tests will verify technologies developed through DOE's core R&D effort and enable implementation of CO(2) sequestration on a large scale, should that become necessary. Pilot projects will have a site-specific focus to test technology; assess formation storage capacity and injectivity; validate and refine existing CO(2) formation models used to determine the transport and fate of CO(2) in the formation; demonstrate the integrity of geologic seals to contain CO(2); validate monitoring, mitigation, and verification (MMV) technologies; define project costs and compare costs of alternatives; assess potential operational and long-term storage risks; address regulatory requirements; and engage and evaluate public acceptance of sequestration technologies. Field validation tests involving both sequestration in geologic formations and terrestrial sequestration are being developed. The results from the Validation Phase will help to confirm the estimates made during the Characterization Phase and will be used to update the regional atlases and NatCarb.

In the United States, projected population growth rates, energy consumption patterns, and demand from competing water use sectors will increase pressure on power generators to reduce water use. Water availability and use also exhibit strong regional variations, complicating the nature of public policy and technological response. The US Department of Energy's (DOE) National Energy Technology Laboratory (NETL) is engaged in a research and development (R&D) program to reduce freshwater withdrawal (total quantity of water utilized) and consumption (portion of withdrawal not returned to the source) from existing and future thermoelectric power generating facilities. The Innovations for Existing Plants (IEP) Program is currently developing technologies in 5 categories of water management projects to reduce water use while minimizing the impacts of plant operations on water quality. This paper outlines the freshwater withdrawal and consumption rates for various thermoelectric power generating types and then estimates the potential benefits of IEP program technologies at both the national and regional levels in the year 2030. NETL is working to protect and conserve water resources while leveraging domestic fossil fuel resources, such as coal, to increase national energy security.

Data presented herein provide a preliminary assessment of the overall feasibility of this treatment concept. The Carbonation capacity of bauxite residue/brine mixtures was considered over the full range of reactant mixture combinations in 10% increments by volume. A bauxite residue/brine mixture of 90/10 by volume exhibited a CO sub(2) sequestration capacity of greater than 9.5 g/L when exposed to pure CO sub(2) at 20 degree C and 0.689 MPa (100 psig). Dawsonite and calcite formation were predicted to be the dominant products of bauxite/brine mixture carbonation. It is demonstrated that CO sub(2) sequestration is augmented by adding bauxite residue as a caustic agent to acidic brine solutions and that trapping is accomplished through both mineralization and solubilization. The product mixture solution was, in nearly all mixtures, neutralized following carbonation. However, in samples (bauxite residue/brine mixture of 90/10 by volume) containing bauxite residue solids, the pH was observed to gradually increase to as high as 9.7 after aging for 33 days, suggesting that the CO sub(2) sequestration capacity of the samples increases with aging. Our geochemical models generally predicted the experimental results of carbon sequestration capacities and solution pH.

These data were collected at temperatures of 22 and 75 degree C and pressures between 100 and 450 bar. Experimentally determined data were compared with CO sub(2) solubility predictions using a model developed by Duan and Sun (Chem. Geol. 2003, 193, 257-271). Model results compare well with Oriskany brine CO sub(2) solubility data collected experimentally, suggesting that the Duan and Sun model is a reliable tool for estimating solution CO sub(2) capacity in high salinity aquifers in the temperature and pressure range evaluated. The capacity for the Oriskany formation to sequester dissolved CO sub(2) was calculated using results of the solubility models, estimation of the density of CO sub(2) saturated brine, and available geographic information system (GIS) information on the formation depth and thickness. Results indicate that the Oriskany formation can hold approximately 0.36 gigatonnes of dissolved CO sub(2) if the full basin is considered. When only the region where supercritical CO sub(2) can exist (temperatures greater than 31 degree C and pressures greater than 74 bar) is considered, the capacity of the Oriskany formation to sequester dissolved CO sub(2) is 0.31 gigatonnes. The capacity estimate considering the potential to sequester free-phase supercritical CO sub(2) if brine were displaced from formation pore space is 8.8 gigatonnes in the Oriskany formation.

In the U.S., energy-relatedactivities account for 75% of anthropogenic greenhouse gas (GHG) emissions, with more than 50% from largestationary sources such as power plants and about one-third from transportation. Mitigation technologies forCO2 atmospheric stabilization based on energy and economic scenarios include coal-based power plant-carbon capture and storage (CCS), and the U.S. Department of Energy (DOE) is assessing CCS operations andsupporting technologies at U.S. locations and opportunities abroad reported here. The Algerian In Salah JointIndustry Project injecting 1 million tons CO2 (MtCO2)/year into a gas field sandstone, and theCanadian Weyburn-Midale CO2 Monitoring and Storage Project injecting over 1.8 MtCO2/year intocarbonate oil reservoirs are ongoing industrial-scale storage operations DOE participates in. DOE also supports mid-scale CCS demonstrations at the Australian Otway Project and CO2SINK in Germany. Enhanced oilrecovery operations conducted for decades in west Texas and elsewhere have provided the industrial experienceto build on, and early pilots such as Frio-I Texas in 2004 have spearheaded technology deployment. Whileinjecting 1,600 tons of CO2 into a saline sandstone at Frio, time-lapse borehole and surface seismicdetected P-wave velocity decreases and reflection amplitude changes resulting from the replacement of brinewith CO2 in the reservoir. Just two of many cutting-edge technologies tested at Frio, these and others arenow deployed by U.S. researchers with international teams to evaluate reservoir injectivity, capacity, and integrity,as well as to assess CO2 spatial distribution, trapping, and unlikely leakage. Time-lapse Vertical SeismicProfiling at Otway and microseismic at In Salah and Otway, monitor injection and reservoir conditions withgeophysics. Borehole-based technologies include a novel geochemical two-phase reservoir sampler deployedat Otway, and thermal-based measurements at CO2SINK for coupled hydrologic-geochemical reservoiranalyses. Seismic, geomechanical, hydrologic, geochemical, and core studies are used in a multidisciplinaryapproach to assess CO2 trapping and reservoir integrity at In Salah. With estimated lifetime storage of 17MtCO2 at In Salah, this and other CCS demonstrations provide opportunities to gain commercial experience for advancing coal-based power generation-CCS for carbon management.

The tertiary amine immobilized in these solid substrates was 1, 8 Diazabicyclo-[5.4.0]-undec-7-ene (DBU) and it has the stoichiometric capability of capturing carbon dioxide at a 1:1 R-NH sub(2):CO sub(2) molar ratio. This is a unique feature compared to other primary and secondary amines which capture CO sub(2) at a 2:1 molar ratio, thus making the immobilized DBU solid sorbents competitive with existing commercially available sorbents and liquid amine-based capture systems. The immobilized DBU solid sorbents prepared in this study exhibit acceptable CO sub(2) capture capacities of 3.0 mol CO sub(2)/kg sorbent at 298 K; however, at the critical operational temperature of 338 K, the capacity was reduced to 2.3 mol/kg sorbent. The DBU sorbents did exhibit acceptable stability over the adsorption/desorption temperature range of 298-360 K based on XPS and TGA analyses.

Therefore, it is critical to develop technologies to mitigate this problem. One very promising approach to reducing CO sub(2) emissions is CO sub(2) capture at a power plant, transport to an injection site, and sequestration for long-term storage in any of a variety of suitable geologic formations. However, if the promise of this approach is to come to fruition, capture costs will have to be reduced. The Department of Energy's Carbon Sequestration Program is actively pursuing this goal. CO sub(2) capture from coal-derived power generation can be achieved by various approaches: post-combustion capture, pre-combustion capture, and oxy-combustion. All three of these pathways are under investigation, some at an early stage of development. A wide variety of separation techniques is being pursued, including gas phase separation, absorption into a liquid, and adsorption on a solid, as well as hybrid processes, such as adsorption/membrane systems. Current efforts cover not only improvements to state-of-the-art technologies but also development of several innovative concepts, such as metal organic frameworks, ionic liquids, and enzyme-based systems. This paper discusses the current status of the development of CO sub(2) capture technology.

This study investigated the inter-laboratory reproducibility of carbon dioxide isotherm measurements on moisture-equilibrated Argonne premium coal samples (Pocahontas No. 3, Illinois No. 6, and Beulah Zap). Six independent laboratories provided isotherm data on the three moisture-equilibrated coal samples at 55 degrees C and pressures up to 15 MPa. Agreement among the laboratories was good up to 8 MPa. At the higher pressures, the data among the laboratories diverged significantly for two of the laboratories and coincided reasonably well for four of the laboratories.

LOUIS COUNTIES, MINNESOTA. AN - 36341088; 13007 AB - PURPOSE: The granting of funds for the construction and demonstration of a coal-based integrated gasification combined cycle (IGCC) electric power plant demonstration project to be located in the Taconite Tax Relief Area (TTRA) of Itasca and St. Louis counties, Minnesota is proposed. The TTRA encompasses 13,000 square miles in northeastern Minnesota from Crosby to the north shore of Lake Superior. Excelsior Energy Inc. would design, construct, and operate the Mesaba Energy Project in two phases; each phase would nominally generate 606 megawatts (MW) of electricity for export to the electrical grid, for a total output of 1,212 MW at full buildout. IGCC meets the goals of the CCPI by utilizing an estimated 240-year domestic supply off reliable, low-cost coal in an environmentally acceptable manner. The project would demonstrate advanced IGCC technologies to produce electricity, including advanced gasification and air separation systems, feedstock flexibility, improved environmental performance characteristics, and improved thermal efficiency. The technologies would be more efficient, economical, reliable, and environmentally favorable than conventional coal-fueled steam electric generation plants. After a one-year demonstration period, if economically feasible, the Mesaba IGCC power plant could be operated commercially for a period of 20 years or longer. Mesaba would employ IGCC technology, using Conoco-Phillips E-Gas technology. Gasification is the process of converting coal, petroleum coke, or blends of these feedstocks to a gaseous fuel called synthesis gas. A combined-cycle electric power plant uses both a steam turbine generator and a combustion generator at one location to generate electricity. Combining the gasification process with the combined-cycle power plant is known as IGCC, which is an inherently lower-polluting and more energy-efficient technology for producing electricity from solid feedstocks. Coal would be delivered to the site by a subsidiary of CN Railway. Electricity would be transmitted to the regional grid by power lines constructed within the TTRA. The Department of Energy (DOE) would provide $36 million in co-funding, through a cooperative agreement with Excelsior under the Clean Coal Power Initiative (CCPI) Program for the design and one-year first-phase operational demonstration testing period. The DOE may also provide a loan guarantee to Excelsior pursuant to the Energy Policy Act of 2005 to guarantee a portion of the private sector financing off the project; however, this potential loan guarantee is not part of DOE's proposed action. The cost of the first phase is estimated at $2.16 billion. In addition to the proposed action, this draft EIS considers a No Action Alternative and alternative sites for the demonstration project. POSITIVE IMPACTS: The proposed power plant would demonstrate the commercial readiness of the Conoco-Philips E-Gas gasification technology in a fully integrated and quintessential IGCC utility-scale application. Such a demonstration would accelerate the commercialization of clean coal technologies capable of achieving substantial efficiencies, environmental performance, and cost-competitiveness. NEGATIVE IMPACTS: The plant footprint would occupy 192 acres, which would be cleared of vegetation and the associated wildlife habitat of 137 acres of the affected soils are classified as prime farmland, though this land supports no agricultural uses. Site grading and preparation would require 2.97 million cubic yards of cut land and 1.75 million cubic yards of fill. Natural gas pipeline rights-of-way would displace 142 to 171 acres of prime farmland, and transmission line rights-of-way would disturb up to 151 acres of prime farmland. The power plant site and related transmission and pipeline facilities would lie within the Western Mesabi Iron Range Early Mining Landscape District and several individual historic sites would be directly affected.

AN - 36341052; 12992 AB - PURPOSE: The construction and operation of a project designed to demonstrate technology for the production of electricity, steam, and liquid fuels from anthracite coal waste (culm) in Gilberton, Schuykill County of eastern Pennsylvania is proposed. The project has been selected by the Department of Energy for $100 million in cost-shared funding under the Clean Coal Power Initiative to demonstrate the integration of coal waste gasification and Fisher-Tropsch (F-T) synthesis of liquid hydrocarbon fuels at commercial scale. The proposed facilities would use a gasifier to convert coal waste to synthesis gas, which would be conveyed to F-T liquefaction facilities for production of liquid fuels and to a combined-cycle power plant. For coal gasification, the plant would use Shell technology, which has operated commercially using coal feedstock in The Netherlands since the 1990s. For liquefaction, the SASOL F-T technology, which has operated commercially in South Africa since the 1980s, would be used. The power plant would use the synthesis gas to drive a gas combustion turbine and exhaust gas from the gas turbine to generate steam from water to drive a steam turbine. Both turbines would generate electricity. The project would be located adjacent to the existing Gilberton Power Plant. The primary feedstock for the facilities would be low-cost anthracite culm, which is locally abundant. In addition to culm, the facility would be capable of using a blend of feedstock containing up to 25 percent petroleum coke, though no petroleum coke would be used during the demonstration period. The facility would produce 5,000 barrels of liquid fuels and 41 megawatts of electricity per day. The area is primarily rural with a mixture of industrial, commercial, and residential land use. Construction of the facilities would begin in early 2006 and continue until mid-2008. The demonstration phase would be conducted from 2008 until mid-2011. If the demonstration were successful, commercial operation would follow immediately. The facility would be designed for a 26-year life. Total cost of the project is estimated at approximately $612 million. A December 2006 supplement to the November 2005 draft EIS on proposed project corrects information regarding carbon dioxide emissions from the proposed plant, provided information on the feasibility of carbon sequestration of carbon dioxide emissions from the plant, and presents additional information regarding carbon dioxide-related cumulative impacts associated with potential future development of the demonstration technology. This final EIS incorporates the presentation of both the draft EIS and the supplement, which is included as an appendix, and forwards the same proposal as that outlined in the two earlier documents; this document also considers a No Action Alternative. POSITIVE IMPACTS: The project would demonstrate the ability for the F-T technology to generate clean, reliable, and affordable electricity for the commercial marketplace. As a result, technical, environmental, and financial data would be generated from the design, construction, and operation of the integrated technologies at a sufficiently large scale to allow industries and utilities to assess the project's potential for commercial application. While individual technologies have been independently operated, this project would demonstrate the integration of technologies that may ultimately reduce the nation's dependence on imported oil. The project could result in the recycling of up to 100 tons of anthracite coal waste dumped in the area and the potential extension of the technology to other areas of the country where culm buildups need attention to address issues related to waste disposal and land reclamation. Over 26 years, 1,000 acres of land would be reclaimed following culm removal. An average of 516 workers would be employed during the construction phase, approximately 250 workers during the demonstration phase, and 150 for long-term operation. NEGATIVE IMPACTS: Construction and operation activities would displace 76.5 acres of deciduous forest habitat, Five 200-foot and one 300-foot stacks would mar visual aesthetics in the area, but these would be shorter than the 326-foot stack at the adjacent Gilberton Power Plant. Plant operation would release sulfur dioxide, nitrogen dioxide, particulate matter, and carbon monoxide; only nitrogen dioxide levels would be significant. Subsidence could affect transfer lines and related facilities in the Mahanoy Creek valley. LEGAL MANDATES: Clean Coal Power Initiative, Fiscal Year 2003.

It allows the chemistry of the leaching process to be studied in more detail than achievable with more traditional batch and column techniques. The continuous stirring provides constant mixing as occurs in more traditional batch-leaching tests while the continuous flow provides data over a wide range of pH values and liquid/solid ratios such as those seen in column leaching studies. Metal release patterns were examined in detail over a range of pH values extending from the material's natural, slightly alkaline pH to acidic pH conditions. The leaching behavior of individual elements depends on several factors including, but not limited to, the solubility of the mineral phases present, the sorption properties of the remaining phases and the neutralization capacity of the minerals. Bulk FGD gypsum is moderately soluble; dissolution is controlled by its solubility product and hydration reactions rather than pH. Elution and pH profiles indicate the presence of alkaline material(s) that buffers the system during the initial leaching. Iron and aluminum are not leached until the buffering capacity is exhausted. Elements bound to these phases can be mobilized during the low-pH dissolution. Metals not released during leaching become concentrated in a minor, insoluble residue remaining at the end of each experiment. Understanding the fundamental mechanisms operating during the leaching process provides a basis for evaluating the safety of FGD byproducts and ensuring these materials are used and disposed of appropriately. This information may also provide a basis for capture and sequestration technologies for mercury and other metals.

This is being investigated with a sequential extraction scheme that subjects FGD material to a series of phase-targeted reagents. Mineral phases with the greatest affinity for Hg and the form in which Hg is naturally immobilized can be discovered by observing the amount of Hg mobilized by each successive extracting solution. The procedure involves a series of batch extractions, including a water rinse to remove water soluble and loosely sorbed ions, 0.11 M acetic acid to target carbonate minerals and exchangeable ions, 0.1 M hydroxylamine hydrochloride to dissolve manganese oxides and hydroxides, 0.25 M hydroxylamine hydrochloride in 0.25 M HCl to dissolve iron oxides and hydroxides, and hydrogen peroxide and 0.1 M ammonium acetate to oxidize organic matter and dissolve sulfide minerals. All extractions were conducted at room temperature except the second hydroxylamine hydrochloride step and the hydrogen peroxide steps, which were performed in a bath heated to at least 80 degrees C. Some samples were tested after a prolonged water rinse to dissolve the gypsum phase, others were tested as-received. Results indicate that Hg is associated with two distinct fractions of FGD materials. Most of the solubilized Hg is extracted by the iron oxide and hydroxide dissolution reagent. Repeated applications of this reagent suggest that Hg is retained with more resistant iron phases. Hg release occurred under extremely acidic (pH<1) and reducing conditions. Analysis of the extracts indicates the presence of a minor phase (possibly clay minerals) that may also be associated with retained Hg. The organic matter and sulfide minerals fraction typically yields lower but still significant amounts of Hg.

In this scheme, partially combusted coal from the furnace of a pulverized coal power generation plant is extracted by a lance and then re-injected into the ductwork downstream of the air preheater. Recent results on a 500-lb/h pilot-scale combustion facility show similar removals of mercury for both the Thief Process and ACI. The tests conducted to date at laboratory, bench, and pilot-scales demonstrate that the Thief sorbents exhibit capacities for mercury from flue gas streams that are comparable to those exhibited by commercially available activated carbons. A patent for the process was issued in February 2003. The Thief sorbents are cheaper than commercially-available activated carbons; exhibit excellent capacities for mercury; and the overall process holds great potential for reducing the cost of mercury removal from flue gas. The Thief Process was licensed to Mobotec USA, Inc. in May of 2005.

13635808 AB - Over 70 wood chemical plants operated in northern Pennsylvania between ca. 1890 and 1950, all located within 72km of the New York state border. Their original purpose was to salvage the small unwanted hardwood trees left behind by the lumber mills, and to make charcoal, calcium acetate and methanol for a number of industrial uses via destructive distillation. At many old wood chemical plant sites, unknown quantities of wood tar remain as a residual contaminant and pose a pollution threat to aquatic life in nearby streams. Research on the composition and properties of residual wood tars from five abandoned industrial sites in Pennsylvania are described. Weathered wood tars were more viscous and contained fewer volatile and semivolatile organic compounds than did soil-buried tars. Phenol, 2-methylphenol (o-cresol), 4-methylphenol (p-cresol), and 2, 4-dimethylphenol were found in all sampled tars. These water-soluble phenolic compounds were released quasi-instantaneously in aqueous solution, followed by a slower rate of release, consistent with the behavior of similar compounds in other dense non-aqueous liquids. Air-exposed wood tar deposits developed a hard crust, which contained fewer volatiles and semivolatiles and had a higher softening point than other samples. These tars eroded to form a powdered soil colonized by lichens and mosses. Residual wood tar material found at one site was shown to be thermally altered, likely during the historical destruction of the chemical plant by fire. Recovered wood tar wastes have a relatively high heating value and may have use as a potential, but limited, alternate energy source.

AN - 36340880; 12863 AB - PURPOSE: The provision of federal funding to FutureGen Alliance, Inc. (Alliance) for the design, construction, and operation of a coal-fueled electric power and hydrogen gas production plant integrated with carbon dioxide capture and geologic sequestration at one of four sites in Illinois or Texas is proposed. The sites under consideration include a 444-acre site in Mattoon, Illinois; a 345-acres site in Tuscola, Illinois; a 400-acre site in Jewett, Texas; and a 600-acre site in Odessa, Texas. The FutureGen project would help promote diverse and secure sources of energy and the expected need for coal to plan a significant role in providing that energy as outlined in the FutureGen Initiative announced by President George W. Bush on February 27, 2003. Alliance is a non-profit industrial consortium led by the coal-fueled electric power industry and the coal production industry. The Department of Energy (DOE) and Alliance have signed a FUll Scope Cooperative Agreement to undertake the FutureGen Project. The agreement defines the terms and conditions for financial assistance, including DOE's oversight role. Under the agreement, Alliance would be primarily responsible for implementing the FutureGen Project. Major components of the project would include a power plant site and plant infrastructure; a sequestration site for carbon dioxide injection wells and related surface infrastructure, a deep geologic saline formation where carbon dioxide would be sequestered; utility connections and corridors for water supply, sanitary wastewater transportation, electric transmission, natural gas transportation and carbon dioxide transpiration; and rail and truck transportation facilities. Cost of the project, which is estimated at $950 million in constant 2004 dollars, would be shared at a 74/26 ratio by the federal government and Alliance. Accounting for inflation, based on representative industry indices, the project is currently estimated to cost $1.76 billion in as-spent dollars. Accounting for $300.8 million in expected revenues from the sale of electricity generated by the project, the total net project cost is estimated at $1.46 million, which includes at least $80 million in projected contributions from foreign governments. POSITIVE IMPACTS: The demonstration project would provide a research platform supporting the goal of developing clean coal technology via the creation of low-cost, zero-emission power plants with efficiencies close to double that of today's available technology. In addition to the FutureGen Initiative, the project would support the Climate Change Technology Initiative, instituted on January 28, 2003, helping to reduce greenhouse gas emissions from coal-fired energy production. NEGATIVE IMPACTS: Construction activities would result in the displacement of 200 acres of vegetation and disturbance of the associated soils and wildlife habitat. If either the Maatoon or Tuscola site was selected, prime farmland would be displaced. Groundwater withdrawal would occur at the Tuscola, Jewett, or Odessa site, with the related impacts most extreme at the Odessa site. Operation of the plant would result in emissions of criteria and hazardous air pollutants, including those from unplanned restarts and flaring events. Residents within a two-mile radius would be most affected by pollutant emissions fueling unplanned restarts and flaring events. Cultural resources could be affected along the Jewett or Odessa carbon dioxide corridor or the Tuscola electrical transmission corridor. If sited at Mattoon or Tuscola, the plant would significantly mar area visual aesthetics. LEGAL MANDATES: Department of Energy Organization Act of 1977 (P.L. 95-91).

AN - 70600657; 17571837 AB - Biomass from a prototype reactor was used to investigate the kinetics of chemoheterotrophic reduction of solutions of ferric ethylenediaminetetraacetic acid (EDTA) and solutions containing the nitrosyl adduct of ferrous EDTA using ethanol as the primary electron donor and carbon source. A series of batch experiments were conducted using biomass extracted from the scrubber solution treatment and regeneration stage of a prototype iron EDTA-based unit process for the absorption of nitric oxide with subsequent biological treatment. Using a linear-sweep voltammetric method for analysis of the ferric EDTA concentration, iron-reducing bacteria were found to behave according to the Monod kinetic model, at initial concentrations up to 2.16 g chemical oxygen demand (COD) as ethanol per liter, with a half-velocity constant of 0.532 g COD as ethanol/L and a maximum specific utilization rate of 0.127 mol/L of ferric ethylenediamine-tetraacetic acid [Fe(III)EDTA]*(g volatile suspended solids [VSS]/L)d(-1). Based on batch analyses, biomass yield and endogenous decay values of iron-reducing bacteria were estimated to be 0.055 g VSS/g COD and 0.017 L/d, respectively. An average of 1.64 times the theoretical (stoichiometric) demand of ethanol was used to complete reduction reactions. Kinetics of the reduction of the nitrosyl adduct of ferrous EDTA are summarized by the following kinetic constants: half-velocity constant (Ks) of 0.39 g COD/L, maximum specific utilization rate (k) of 0.2 mol/L [NO x Fe(II)EDTA(2-)](g VSS/L)d(-1), and inhibition constant (K(I)) of 0.33 g COD/L, as applied to the modified Monod kinetic expression described herein. Based on batch analyses, the biomass yield of nitrosyl-adduct-reducing bacteria was estimated to be 0.259 g VSS/g COD, endogenous decay was experimentally determined to be 0.0569 L/d, and an average of 1.26 times the stoichiometric demand of ethanol was used to complete reduction reactions.

Development of methods to estimate CO (sub 2) leakage rates is essential to assure that storage objectives are being met at sequestration facilities. Perfluorocarbon tracers (PFTs) were added as three 12 h slugs at about one week intervals during the injection of 2090 tons of CO (sub 2) into the West Pearl Queen (WPQ) depleted oil formation, sequestration pilot study site located in SE New Mexico. The CO (sub 2) was injected into the Permian Queen Formation. Leakage was monitored in soil-gas using a matrix of 40 capillary adsorbent tubes (CATs) left in the soil for periods ranging from days to months. The tracers, perfluoro-1,2-dimethylcyclohexane (PDCH), perfluorotrimethylcyclohexane (PTCH) and perfluorodimethylcyclobutane (PDCB), were analyzed using thermal desorption, and gas chromatography with electron capture detection. Monitoring was designed to look for immediate leakage, such as at the injection well bore and at nearby wells, and to develop the technology to estimate overall CO (sub 2) leak rates based on the use of PFTs. Tracers were detected in soil-gas at the monitoring sites 50 m from the injection well within days of injection. Tracers continued to escape over the following years. Leakage appears to have emanated from the vicinity of the injection well in a radial pattern to about 100 m and in directional patterns to 300 m. Leakage rates were estimated for the 3 tracers from each of the 4 sets of CATs in place following the start of CO (sub 2) injection. Leakage was fairly uniform during this period. As a first approximation, the CO (sub 2) leak rate was estimated at about 0.0085% of the total CO (sub 2) sequestered per annum.

This model has been validated quantitatively, in the very different limits of zero viscosity ratio and zero capillary number; flow patterns from modeling agree well with experiment. For a range of stable viscosity ratios (mu (sub injected) /mu (sub displaced) >1), we have increased the capillary number, N (sub c) , and studied the way in which the flows deviate from capillary fingering (the fractal flow of invasion percolation) and become compact for realistic capillary numbers. Results exhibiting this crossover from capillary fingering to compact invasion are presented for the average position of the injected fluid, the fluid-fluid interface, the saturation and fractional flow profiles, and the relative permeabilities. The agreement between our results and earlier theoretical predictions [Blunt M, King MJ, Scher H. Simulation and theory of two-phase flow in porous media. Phys Rev A 1992;46:7680-99; Lenormand R. Flow through porous media: limits of fractal patterns. Proc Roy Soc A 1989;423:159-68; Wilkinson D. Percolation effects in immiscible displacement. Phys Rev A 1986;34:1380-90; Xu B, Yortsos YC, Salin D. Invasion Percolation with viscous forces. Phys Rev E 1998;57:739-51] supports the validity of these general theoretical arguments, which were independent of the details of the porous media in both two and three dimensions.

AN - 36343978; 12613 AB - PURPOSE: The construction and operation of coal gasification facilities at the Orlando Utility Commission's existing Stanton Energy Center near Orlando, Florida are proposed. The center is located on a 3,280-acre site in eastern Orange County, three miles east of the city limits of Orlando and 13 miles east-southeast of the downtown area. The project, proposed by the Southern Company, has been selected for federal funding under the Clean Coal Power Initiative to demonstrate advanced power general systems using integrated gasification combined cycle (IGCC) technology. Although the Department of Energy would support only the Orlando Gasification Project (i.e., coal gasifier, synthesis gas cleanup systems, and supporting infrastructure), the project would be integrated with a planned, privately funded combined-cycle unit, which together would constitute the IGCC facilities. The facilities would convert coal into synthesis gas to drive a gas combustion turbine. Combined, the two turbines would generate 285 megawatts of electricity. Key issues identified during scoping include those related to land use, aesthetics, air quality, geology, water resources, floodplains, wetlands, ecological resources, social and economic resources, waste management, human health and safety, and noise. Facility construction would begin in 2007 and continue until early 2010. After mechanical checkout of the facilities, demonstration, including analysis and process evaluation, would be conducted over a 4.5-year period from mid-2010 until late 2014. If the demonstration was successful, commercial operation would begin immediately. Cost of the project is estimated at $569 million toward which the federal government would provide $235 million. In addition to the proposed action, this final EIS considers a No Action Alternative. POSITIVE IMPACTS: The project would provide a source of electricity that si reliable, low-cost, environmentally sound, and more efficient than conventional coal-fired power plants. The facilities would substantially reduce emissions of sulfur dioxide, oxides of nitrogen, and mercury as compared to conventional coal-fired plants. The IGCC facilities would demonstrate advanced coal gasification technology for use in the generation of electric power at a sufficiently large scale to allow industries and utilities to assess the project's potential for commercial application. A successful demonstration would generate technical, environmental, and financial data from the design, construction, and operation of the facilities to confirm that the technology could be implemented at a commercial scale. The cost-share contribution by the federal government would help reduce the risk to the Southern Company team in demonstrating the IGCC technology at the level of maturity needed for decisions regarding commercialization. Construction activities would employ an average of 350 workers, with a peak construction employment roll of 600 to 700 workers. NEGATIVE IMPACTS: The IGCC facilities and related developments would displace 35 acres of land. The associated transmission line would displace 5.8 acres of pine flatwoods habitat and hydric pine savanna and cypress wetlands. Annual emissions of criteria pollutants would include 162 tons of sulfur dioxide, 1,006 tons of nitrogen oxides, 189 tons of particulate matter, 654 tons of carbon monoxide, 0.03 tons of lead. The 205-foot heat recovery steam generator stack, 1740foot gasifier structure, and 114-foot heat recovery steam generator structure would add to the visual impact of the site, which already contains two 550-foot stacks serving other generation units.

In a laboratory study on spontaneous combustion, samples of coal, coal refuse, and carbonaceous shale were heated at a controlled rate between ambient temperature and 250 degrees C. In these experiments, the concentration of O (sub 2) was not limited and the concentration of CO (sub 2) increased with increasing temperature to a maximum of 10%. Carbon monoxide was not detected at temperatures below 100 degrees C, and the maximum concentration of CO was less than 4%. In field studies, samples of combustion gases were obtained from fires in three abandoned coal mines. These indicated a linear increase in the concentration of CO (sub 2) relative to the decreased concentration of O (sub 2) . At an O (sub 2) concentration of 2%, the CO (sub 2) concentration approached 15%, and CO was detected only when the O (sub 2) concentration was less than 8%. At temperatures over 50 degrees C, the rate of desorption of CH (sub 4) also increased, but the average concentration in the mine atmosphere was 0.20%. These laboratory experiments and field studies indicate that the rate of gas production is controlled by O (sub 2) concentration and temperature, but physical factors, such as overburden fracturing and differences between surface and subsurface temperature and pressure, control the rate of emission to the atmosphere. In coal-mine fires, both chemical and physical factors control the rate and magnitude of contributions to the atmospheric concentration of greenhouse gases.

Evaluation of site integrity is important in the design and implementation stages of the sequestration effort. This study presents some of the background evaluation undertaken of a Fruitland coal pilot sequestration site located in the San Juan basin. The study includes comparison of fracture traces measured in the field and in high resolution QuickBird satellite imagery, along with multi-frequency terrain conductivity surveys and subsurface maps of the surrounding area. Prominent fracture systems are exposed along the edges of mesas formed in the nearly flat-lying Eocene age San Jose Formation. Fracture trend varies considerably, however, rose diagrams reveal two prominent fracture sets: one trending approximately N30E and the other approximately N45W. Analysis of the QuickBird image reveals similar variability along with two prominent sets: one trending N35E and another smaller set trending N50W. Previous studies in the area suggest that the face cleat orientation and direction of preferential flow during CO (sub 2) injection will follow this NE trend. The site lies in the "High Rate Fairway" near a structural low in the Fruitland Formation. Subsurface maps will help determine whether smaller scale folds and faults similar to those observed to the northwest in the Cedar Hill area exist. If present, they may exert additional control on CO (sub 2) flow patterns and serve as potential avenues for CO (sub 2) escape. The study will help National Energy Technology Laboratory scientists position tracer and soil monitors at the site.

The 3-D density distribution of the coal was calculated for the stressed and confined core with, and without CO (sub 2) sorption. We used a dual energy technique to quantify volumetric variations in bulk density and effective atomic number. CO (sub 2) sorption of coal was then investigated at predetermined injection pressures. The density changes in the coal matrix were calculated and correlated with the CO (sub 2) adsorbed for a multitude of regions of interest (ROI) chosen in slices perpendicular to the bedding plane. The results show that even in small core samples, coal heterogeneity is high. Large variation of density was observed in small regions of interest compared to the average density of slices. Also, the coal density distribution was changed significantly due to the CO (sub 2) uptake. This technique seems very useful in calculating density distribution for stressed and confined coal samples and the change in volumetric density distribution due to CO (sub 2) adsorption. Furthermore the kinetics of heterogeneous adsorption and swelling in coal can be determined.

These goals equate to removing environmental and climate change concerns associated with fossil fuel use while simultaneously establishing a foundation for a hydrogen-based economy and a secure energy future in the U.S. Launched in 2000, SECA is an inventive collaboration among government, the private sector and the scientific community to accelerate the development of modular, low-cost, fuel-flexible solid oxide fuel cell (SOFC) systems that can operate on coal gas, natural gas, bio-fuels, diesel fuel and hydrogen. This approach will facilitate deployment into the marketplace by emphasizing cost competitiveness with established technologies while taking advantage of existing fuel distribution infrastructures. SECA's DOE mission is to have its fuel cell systems ready for FutureGen, soon to be the world's cleanest coal-fueled power plant. SECA has surpassed its first set of cost reduction targets providing strong confidence in the 2010 $400/kW goal. By developing fuel cells to operate cost effectively on various fuels, it is building a bridge to the hydrogen economy while solving today's environmental, climate change, and fuel availability issues. The once distant vision of using clean, low-cost fuel cell technology for everyday applications is now within reach.

The initial focus on power electronics has been to understand the interactions between the SOFC stack, the power conditioning subsystem and the application load requirements and dynamic behaviour. Advances in lower-cost and high-efficiency power electronic converters and inverters are a major factor in achieving attractive simple cycle fuel to electricity conversion efficiencies of 50% to 60% for DG fuel cell power plants. Functionality and performance requirements for power conditioning subsystems will vary between the numerous possible applications for SOFC power generation technology, providing a highly interesting and challenging future in power systems product engineering and development.

These experiments showed a significant variation in the initial degradation (9 days of exposure) based on the curing conditions. The high-temperature (50 degree C) and high-pressure (30.3 MPa) curing environment increased the degree of hydration and caused a change in the microstructure and distribution of the Ca(OH) sub(2(s)) phase within the cement. Cement cured at 50 degree C and 30.3 MPa (representing sequestration conditions) proved to be more resistant to carbonic acid attack than cement cured at 22 degree C and 0.1 MPa. The cement cured at 50 degree C and 30.3 MPa exhibited a shallower depth of degradation and displayed a well-defined carbonated zone as compared to cement cured under ambient conditions. This is likely due to smaller, more evenly distributed Ca(OH) sub(2(s)) crystals that provide a uniform and effective barrier to CO sub(2) attack.

Studies focused on the reaction of Ca-, Fe-, and Mg-silicate minerals with gaseous CO sub(2) to form geologically stable, naturally occurring solid carbonate minerals. The research included resource evaluation, kinetic studies, process development, and economic evaluation. An initial cost estimate of similar to $69/ton of CO sub(2) sequestered was improved with process improvements to similar to $54/ton. The scale of ex situ mineral carbonation operations, requiring similar to 55 000 tons of mineral to carbonate, the daily CO sub(2) emissions from a 1-GW, coal-fired power plant, may make such operations impractical.

In order to gain a more complete understanding of the impact of SO sub(x) on ACI, mercury capture was tested under varying conditions of SO sub(2) and SO sub(3) concentrations using a packed bed reactor and simulated flue gas (SFG). The final mercury content of the activated carbons is independent of the SO sub(2) concentration in the SFG, but the presence of SO sub(3) inhibits mercury capture even at the lowest concentration tested (20 ppm). The mercury removal capacity decreases as the sulfur content of the used activated carbons increases from 1 to 10%. In one extreme case, an activated carbon with 10% sulfur, prepared by H sub(2)SO sub(4) impregnation, shows almost no mercury capacity. The results suggest that mercury and sulfur oxides are in competition for the same binding sites on the carbon surface.

Even modest changes in fuel composition or operating conditions can lead to damaging vibrations in a combustor that was otherwise stable. For this reason, active control has been sought to stabilize combustors that must accommodate fuel variability, new operating conditions, etc. Active control of combustion dynamics has been demonstrated in a number of laboratories, single-nozzle test combustors, and even on a fielded engine. In most of these tests, active control was implemented with closed-loop feedback between the observed pressure signal and the phase and gain of imposed fuel perturbations. In contrast, a number of recent papers have shown that open-loop fuel perturbations can disrupt the feedback between acoustics and heat release that drives the oscillation. Compared to the closed-loop case, this approach has some advantages because it may not require high-fidelity fuel actuators, and could be easier to implement. This paper reports experimental tests of open-loop fuel perturbations to control combustion dynamics in a complete gas turbine engine. Results demonstrate the technique was very successful on the test engine and had minimal effect on pollutant emissions. JF - Journal of Engineering for Gas Turbines and Power.

The economic analyses are reported on a plant-specific basis in terms of the cost required to achieve low (50%), mid (70%), and high (90%) levels of mercury removal "above and beyond" the baseline mercury removal achieved by existing emission control equipment. In other words, the levels of mercury control are directly attributable to ACI. Mercury control costs via ACI have been amortized on a current dollar basis. Using a 20-year book life, levelized costs for the incremental increase in cost of electricity (COE), expressed in mills per kilowatt-hour (mills/kWh), and the incremental cost of mercury control, expressed in dollars per pound of mercury removed ($/lb Hg removed), have been calculated for each level of ACI mercury control. For this analysis, the increase in COE varied from 0.14 mills/kWh to 3.92 mills/kWh. Meanwhile, the incremental cost of mercury control ranged from $3810/lb Hg removed to $166 000/lb Hg removed.

Depending on the FGD process, a large portion of this Hg may be incorporated into the FGD slurry and its solid byproducts including synthetic gypsum, a material commonly used in the manufacturing of wallboard. The potential for atmospheric and groundwater releases of Hg arises during the manufacturing processes, during the preparation and use of the manufactured products, and eventually upon disposal of the wallboard or other products. In this paper, the fate and mobility of Hg in FGD products and process streams were investigated. Experimental approaches, including leaching studies and size separation techniques, were used to investigate products including FGD-outlet slurry and wallboard production line samples. Results of the experiments reported here indicate that, in a number of cases, Hg mobility is limited. Further, the agent responsible for the immobilization appears to be not the finer particles of gypsum itself but an iron-rich phase, such as iron coated clay minerals or iron oxide/hydroxide particles, probably introduced with the limestone used to form the SO sub(2)-capture reagent.

The Oriskany Sandstone aquifer was selected for this study because it meets many of the criteria required of a potential sequestration horizon: sufficient subsurface extent to provide for the potential sequestration of significant volumes of carbon dioxide, adequate porosity and permeability, and depths greater than 800 meters permitting carbon dioxide to be injected as a supercritical fluid. To determine the capacity of the Oriskany Sandstone aquifer to trap carbon dioxide as a soluble component, a series of experiments were conducted in natural Oriskany brine solutions. The experiments were conducted at a temperature range of 21-75 degrees Celsius and pressures from 1 to 400 bars. At these temperatures, the carbon dioxide pressure is essentially equivalent to the total pressure. The solubility experiments were conducted in a Dickson-type flexible-cell system. The Dickson-type reaction cell allows gas-saturated fluid samples to be taken into gas-tight syringes without changing in-situ conditions during sampling. Experimental results indicate an increase in carbon dioxide solubility as carbon dioxide pressure increases. The experiments also indicate a decrease in carbon dioxide solubility as temperature increases. The experimental results are in good agreement with theoretical predictions. The calculation of the capacity of an aquifer to trap carbon dioxide as a soluble component requires the determination of the density of the carbon dioxide saturated solution at all locations within the aquifer. The capacity of the aquifer can be determined by combining the solubility of carbon dioxide along with the density, the extent of the formation, and porosity. The density of carbon dioxide saturated Oriskany brine was estimated as a function of temperature and pressure over the full range of conditions studied. The variation in density between brine with and without carbon dioxide increases as pressure increases but does not differ by more than 0.5 percent over the full range of conditions considered.

In this study, we examined the distribution of iron, manganese and trace elements in discharge downstream of one abandoned mine portal and after its entry into Lamberts Run. Construction of a wetland and passive treatment system is slated to begin along this discharge in summer 2006. Dissolved iron and manganese, which were present in the mine discharge at concentrations of 7 and 6 mg/L, respectively, demonstrated sequential precipitation over the approximately 200-m distance between the mine portal and creek. Significant loss of manganese from the water and net accumulation in the sediments was not observed until 100 m downstream of the portal. Trace elements Ba, Co, Cr, Ni and Zn were detected in water, sediment and black coatings on stream cobbles in Lamberts Run. The trace elements are progressively enriched, relative to iron and manganese, respectively through those media. The coatings contained over 55,000 mg/kg manganese and high concentrations of the trace elements. Selenium was at or below the detection limit in water and sediments but substantially enriched in the black coatings (72 mg/kg). Diffusive equilibration in thin film (DET) and redox gel probes were used to measure sediment porewater concentrations at high resolution in the near-surface sediments.

The program works in conjunction with the private sector and the U.S. national laboratories to develop cost-effective technologies to convert coal into hydrogen. Major goals of the program are (i) demonstrate by 2015, a 60 percent efficient central station to produce hydrogen and power from coal at a cost that is 25 percent lower than current coal based technology, (ii) optimize production pathways to produce hydrogen in decentralized locations. The first approach utilizes advances in water gas shift reaction technologies and separation membranes to obtain pure hydrogen that can be used in power generation and transportation applications. The second seeks to produce hydrogen rich liquids fuels and synthetic natural gas from the products of coal gasification by 2012 at a delivered cost less than $3.00/kg of hydrogen. This presentation provides an overview of DOE hydrogen research program and its major accomplishments.

Department of Energy ER - TY - JOUR T1 - Enhanced response of an oligonucleotide-based biosensor to environmental mercury AN - 51247616; 2008-069063 AB - One environmental pollutant of particular relevance to the coal-generated power industry is mercury. Power plants in the U.S., led by Texas, Ohio, Pennsylvania, Indiana, and Alabama, collectively emitted over 90,000 pounds of mercury into the air in 2003. Calls for increased mercury monitoring activities have come from many groups concerned with environmental contamination and mercury bioconcentration in fish. Additionally, the benefits of improvements in the reduction of mercury emissions from existing power plants cannot be seriously evaluated without extensive monitoring of the environment. Low in situ mercury concentrations and the expense of traditional laboratory analyses currently limit such routine and effective monitoring. Microbial biosensors sensitive to mercury have been developed that quantitatively produce light in response to the amount of mercury (II) entering the cells. However, these sensors are typically difficult to prepare, can have long lag times between initial exposure and subsequent light emission, and are difficult to use in the field. Whole cell biosensors using living bacteria also require attention to the growth requirements of the cells, as well as complications brought on by the presence of other toxic compounds in addition to mercury. A "molecular beacon" sensor for mercury (II) reported by Ono and Togashi (Angew. Chem. Int. Ed. 2004, 43:4300-4302.) was modified to enhance its sensitivity and fluorescence response. The basic detection method involves the selective binding of mercury ions to thymine-thymine (T-T) base pairs in DNA duplexes. An oligonucleotide sequence in the sensor changes its conformation upon binding with mercury ions, and causes a fluorophore at one end of the oligonucleotide sequence to come in proximity with a quencher molecule attached to the other end. Enhanced fluorescence resonance energy transfer (FRET) results in a decrease in the intensity of the fluorescence spectrum. The use of fluorescein as a harvester fluorophore and alternative emitter fluorophores dramatically increased the sensitivity of the sensor. The fluorescence spectrum generated by this sensor is analyzed using a field spectrofluorometer, and the analytical approach may be useful in environmental mercury monitoring activities.

One major requirement for the commercial application of geologic sequestration is accurate leak detection; i.e., leak monitoring and accurate estimation of leak volumes through continued monitoring. This is essential to assure that long-term sequestration is achieved. Significant leakage from the sequestration reservoir defeats the purpose of sequestration, which is to stabilize and then reduce atmospheric concentrations of CO (sub 2) for several hundreds to thousands of years. Multiple investigators have attempted to estimate the amount of leakage that is acceptable (e.g., Pacala, 2002; Hepple and Benson, 2002; Dooley and Wise, 2002; Herzog, 2002). Their estimates vary considerably, and range from 1% to 0.01% per annum which leads to leakage of 50% of the injected CO (sub 2) volume in 70 to 7000 years, respectively.

AN - 68902070; 17004685 AB - Apportionment of primary and secondary pollutants during the summer 2001 Pittsburgh Air Quality Study (PAQS) is reported. Several sites were included in PAQS, with the main site (the supersite) adjacent to the Carnegie Mellon University campus in Schenley Park. One of the additional sampling sites was located at the National Energy Technology Laboratory, located approximately 18 km southeast of downtown Pittsburgh. Fine particulate matter (PM2.5) mass, gas-phase volatile organic material (VOM), particulate semivolatile and nonvolatile organic material (NVOM), and ammonium sulfate were apportioned at the two sites into their primary and secondary contributions using the U.S. Environmental Protection Agency UNMIX 2.3 multivariate receptor modeling and analysis software. A portion of each of these species was identified as originating from gasoline and diesel primary mobile sources. Some of the organic material was formed from local secondary transformation processes, whereas the great majority of the secondary sulfate was associated with regional transformation contributions. The results indicated that the diurnal patterns of secondary gas-phase VOM and particulate semivolatile and NVOM were not correlated with secondary ammonium sulfate contributions but were associated with separate formation pathways. These findings are consistent with the bulk of the secondary ammonium sulfate in the Pittsburgh area being the result of contributions from distant transport and, thus, decoupled from local activity involving organic pollutants in the metropolitan area.

The DOE FE fuel cells program has three aspects: the Solid State Energy Conversion Alliance (SECA), Fuel Cell Coal Based Systems for central power, and the High Temperature Electrochemistry Center (HiTEC). The SECA goal is to decrease SOFC system cos to US$ 400 per kilowatt (kW) by 2010 for stationary markets. DOE FE is ultimately concerned with coal-based central power plants such as FutureGen. The goal is to aggregate SECA-type fuel cells into larger systems and to produce a very high efficiency megawatt-class FCT hybrid for testing at FutureGen. The low-cost US$ 400 kW super(-1) SECA FCT hybrid is a key component to achieving 60% efficiency by 2020. Advanced aspects of solid oxide technology are part of HiTEC R&D. Technical progress and advances are discussed for all three program aspects.

AN - 36347459; 12219 AB - PURPOSE: The construction and operation of coal gasification facilities at the Orlando Utility Commission's existing Stanton Energy Center near Orlando, Florida are proposed. The center is located on a 3,280-acre site in eastern Orange County, three miles east of the city limits of Orlando and 13 miles east-southeast of the downtown area. The project, proposed by the Southern Company, has been selected for federal funding under the Clean Coal Power Initiative to demonstrate advanced power general systems using integrated gasification combined cycle (IGCC) technology. Although the Department of Energy would support only the Orlando Gasification Project (i.e., coal gasifier, synthesis gas cleanup systems, and supporting infrastructure), the project would be integrated with a planned, privately funded combined-cycle unit, which together would constitute the IGCC facilities. The facilities would convert coal into synthesis gas to drive a gas combustion turbine. Combined, the two turbines would generate 285 megawatts of electricity. Key issues identified during scoping include those related to land use, aesthetics, air quality, geology, water resources, floodplains, wetlands, ecological resources, social and economic resources, waste management, human health and safety, and noise. Facility construction would begin in 2007 and continue until early 2010. After mechanical checkout of the facilities, demonstration, including analysis and process evaluation, would be conducted over a 4.5-year period from mid-2010 until late 2014. If the demonstration was successful, commercial operation would begin immediately. Cost of the project is estimated at $569 million toward which the federal government would provide $235 million. In addition to the proposed action, this draft EIS considers a No Action Alternative. POSITIVE IMPACTS: The project would provide a source of electricity that is reliable, low-cost, environmentally sound, and more efficient than conventional coal-fired power plants. The facilities would substantially reduce emissions of sulfur dioxide, oxides of nitrogen, and mercury as compared to conventional coal-fired plants. The IGCC facilities would demonstrate advanced coal gasification technology for use in the generation of electric power at a sufficiently large scale to allow industries and utilities to assess the project's potential for commercial application. A successful demonstration would generate technical, environmental, and financial data from the design, construction, and operation of the facilities to confirm that the technology could be implemented at a commercial scale. The cost-share contribution by the federal government would help reduce the risk to the Southern Company team in demonstrating the IGCC technology at the level of maturity needed for decisions regarding commercialization. Construction activities would employ an average of 350 workers, with a peak construction employment roll of 600 to 700 workers. NEGATIVE IMPACTS: The IGCC facilities and related developments would displace 35 acres of land. The associated transmission line would displace 5.8 acres of pine flat woods habitat and hydric pine savanna and cypress wetlands. Annual emissions of criteria pollutants would include 162 tons of sulfur dioxide, 1,006 tons of nitrogen oxides, 189 tons of particulate matter, 654 tons of carbon monoxide, 0.03 tons of lead. The 205-foot heat recovery steam generator stack, 1740foot gasifier structure, and 114-foot heat recovery steam generator structure would add to the visual impact of the site, which already contains two 550-foot stacks serving other generation units.

This process includes a carbonation reaction utilizing a brine solution and CO sub(2) as reactants under mild reaction conditions. CaO rich fly ashes are added to increase the pH level of the reactant brine, maximizing the reaction efficiency of the carbonation reaction. Furthermore, these materials can also provide a source of Ca in addition to the Ca present in the brine for carbonation. The calcium from fly ashes and brine both contribute to the formation of calcium carbonate during the carbonation reaction.

The release of metal ions from fly ash was related to the pH of the leachant solution and to the alkalinity of the ash. The maximum soluble concentration of the metallic elements was measured when the pH of the leachate was less than 5. Twenty-three of the samples were strongly alkaline and buffered the leachate until the ash was neutralized. The leachate from the other 13 samples became acidic with the addition of less than 1 L of 0.1 N acid. The alkalinity of the ash and the volume of acid required to neutralize it were a function of the Ca concentration.

S. Department of Energy. The particle used in this study was a coarse, light material, cork, which has a particle density of 189 kg/m super(3) and a mean diameter of 812 mu m. Fluidizing this material in ambient air approximates the same gas-solids density ratio as coal and coal char in a pressurized gasifier. The purpose of this study is twofold. First, this study is to provide a better understanding on the fundamentals of flow regimes and their transitions. The second purpose of this study is to generate reliable data to validate the mathematical models, which are currently under development at NETL. Utilization of such coarse, light material can greatly facilitate the computation of these mathematical models. Furthermore, the ratio of density of cork to air under ambient conditions is similar to the density ratio of coal to gas at the gasification and pressurized fluidized bed combustion environment. This paper presents and discusses the data, which covered operating flow regime from dilute phase, fast fluidization, and to dense phase transport by varying the solid flux, G sub(s) at a constant gas velocity, U sub(g). Data are presented by mapping the flow regime for coarse cork particles in a Delta P/ Delta L-G sub(S)-U sub(g) plot. The coarse cork particles exhibited different behavior than the published literature measurements on heavier materials such as alumina, sand, FCC, silica gel, etc. A stable operation can be obtained at a fixed riser gas velocity higher than the transport velocity, e.g., at U sub(g)=3.2 m/s, even though the riser is operated within the fast fiuidization flow regime. Depending upon the solids influx, the riser can also be operated at dilute phase or dense phase flow regimes. Experimental data were compared to empirical correlations in published literature for flow regime boundaries as well as solids fractions in the upper dilute and the lower dense regions for fast fluidization flow regime. Comparisons of measured data with these empirical correlations show rather poor agreements. These discrepancies, however, are not surprising since the correlations for these transitions were derived from experimental data of comparative heavier materials such as sands, FCC, iron ore, alumina, etc. JF - Journal of Energy Resources Technology.

However, several key issues, such as underground storage time and the fate of the injected CO (sub 2) , must be studied before this option becomes economically and socially acceptable. In the current study, a one-dimensional reactive mass-transport model was used to predict the long-term chemical behavior of a deep saline aquifer following CO (sub 2) injection, far away from the injection site and representative of basin-scale migration and long-term fate. The dissolution of the injected CO (sub 2) into brine causes a sharp drop in pH, and consequently, the acidic brine aggressively reacts with aquifer minerals. Our model also predicts the dissolution of aluminosilicate minerals with the formation of secondary minerals and the precipitation and dissolution of carbonate minerals and is consistent with laboratory-scale CO (sub 2) core-flooding experiments. However, the extent and development of reaction fronts depend on the reaction rates used. For example, our modeling results indicate that the transport of carbon can be significantly retarded with respect to the flow of the brine itself, and a significant amount of injected CO (sub 2) is immobilized because of mineral trapping. The precise locations and patterns of the carbon reactive transport are sensitive to the reaction rates used, illustrating the need for improved knowledge of reaction kinetics, particularly the in-situ rates of dissolution and precipitation of aluminosilicate minerals, in evaluating mineral trapping of CO (sub 2) in deep geological formations.

Bone viscoelasticity, however, has been found to affect stem primary stability by reducing push-out load. In this investigation, an axisymmetric finite element model of a cylindrical stem and diaphyseal cortical bone section was created in order to parametrically evaluate the effect of bone viscoelasticity on stem push-out while controlling coefficient of friction ( mu =0.15, 0.40, and 1.00) and stem-bone diametral interference ( delta =0.01, 0.05, 0.10, and 0.50 mm). Based on results from a previous study, it was hypothesized that stem-bone interference (i.e., press-fit) would elicit a bone viscoelastic response which would reduce the initial fixation of the stem as measured by push-out load. Results indicate that for all examined combinations of mu and delta , bone viscoelastic behavior reduced the push-out load by a range of 2.6-82.6% due to stress relaxation of the bone. It was found that the push-out load increased with mu for each value of delta , but minimal increases in the push-out load (2.9-4.9%) were observed as delta was increased beyond 0.10 mm. Within the range of variables reported for this study, it was concluded that bone viscoelastic behavior, namely stress relaxation, has an asymptotic affect on stem contact pressure, which reduces stem push-out load. It was also found that higher levels of coefficient of friction are beneficial to primary fixation, and that an interference 1"threshold" exists beyond which no additional gains in push-out load are achieved.

AN - 67654083; 16471684 AB - The adsorption and dissociation of carbon monoxide on the W(111) surface is studied with density functional theory. The CO molecule is found to adsorb in end-on configurations (alpha states) and inclined configurations (beta states). The dissociation of the most strongly bound beta state CO is found to have an activation energy of about 0.8 eV, which is lower than the energy required to desorb CO molecularly from the surface. The diffusion of CO and O on W(111) is predicted to be facile at room temperature, whereas C atoms are virtually immobile up to approximately 600 K, according to our calculations. Preadsorbed carbon atoms are shown to prevent the dissociation of CO by blocking the most strongly bound beta state adsorption site and by blocking the dissociation pathway. We predict that dissociation of CO on W(111) is a self-poisoning process. JF - The journal of physical chemistry.

AN - 36348071; 12606 AB - PURPOSE: The construction and operation of a project designed to demonstrate technology for the production of electricity, steam, and liquid fuels from anthracite coal waste (culm) in Gilberton, Schuykill County of eastern Pennsylvania is proposed. The project has been selected by the Department of Energy for $100 million in cost-sharing funding under the Clean Coal Power Initiative to demonstrate the integration of coal waste gasification and Fisher-Tropsch (F-T) synthesis of liquid hydrocarbon fuels at commercial scale. The proposed facilities would use a gasifier to convert coal waste to synthesis gas, which would be conveyed to F-T liquefaction facilities for production of liquid fuels and to a combined-cycle power plant. For coal gasification, the plant would use Shell technology, which has operated commercially using coal feedstock in The Netherlands since the 1990s. For liquefaction, the SASOL F-T technology, which has operated commercially in South Africa since the 1980s, would be used. The power plant would use the synthesis gas to drive a gas combustion turbine and exhaust gas from the gas turbine to generate steam from water to drive a steam turbine. Both turbines would generate electricity. The project would be located adjacent to the existing Gilberton Power Plant. The primary feedstock for the facilities would be low-cost anthracite culm, which is locally abundant. In addition to culm, the facility would be capable of using a blend of feedstock containing up to 25 percent petroleum coke, though no petroleum coke would be used during the demonstration period. The facility would produce 5,000 barrels of liquid fuels and 41 megawatts of electricity per day. The area is primarily rural with a mixture of industrial, commercial, and residential land use. Construction of the facilities would begin in early 2006 and continue until mid-2008. The demonstration phase would be conducted from 2008 until mid-2011. If the demonstration were successful, commercial operation would follow immediately. The facility would be designed for a 26-year life. Total cost of the project is estimated at approximately $612 million. This supplement to the November 2005 draft EIS on proposed project corrects information regarding carbon dioxide emissions from the proposed plant, provides information on the feasibility of carbon sequestration of carbon dioxide emissions from the plant, and presents additional information regarding carbon dioxide-related cumulative impacts associated with potential future development of the demonstration technology. POSITIVE IMPACTS: The project would demonstrate the ability for the F-T technology to generate clean, reliable, and affordable electricity for the commercial marketplace. As a result, technical, environmental, and financial data would be generated from the design, construction, and operation of the integrated technologies at a sufficiently large scale to allow industries and utilities to assess the project's potential for commercial application. While individual technologies have been independently operated, this project would demonstrate the integration of technologies that may ultimately reduce the nation's dependence on imported oil. The project could result in the recycling of up to 100 tons of anthracite coal waste dumped in the area and the potential extension of the technology to other areas of the country where culm buildups need attention to address issues related to waste disposal and land reclamation. Over 26 years, 1,000 acres of land would be reclaimed following culm removal. An average of 516 workers would be employed during the construction phase, approximately 250 workers during the demonstration phase, and 150 for long-term operation. NEGATIVE IMPACTS: Construction and operation activities would displace 76.5 acres of deciduous forest habitat, Five 200-foot and one 300-foot stacks would mar visual aesthetics in the area, but these would be shorter than the 326-foot stack at the adjacent Gilberton Power Plant. Plant operation would release sulfur dioxide, nitrogen dioxide, particulate matter, and carbon monoxide; only nitrogen dioxide levels would be significant. Subsidence could affect transfer lines and related facilities in the Mahanoy Creek valley. LEGAL MANDATES: Clean Coal Power Initiative, Fiscal Year 2003.

The four catalysts tested were Ir, Ir/HCl, Darco FGD activated carbon, and Thief/HCl. The Thief/HCl and Darco converted the highest percentage of the inlet mercury; however, the high conversion in these experiments was aided by larger catalyst loadings than in the Ir and Ir/HCl experiments. We propose a method for analyzing mercury oxidation catalyst results in a kinetic framework using the bulk reaction rate for oxidized mercury formation normalized by either the catalyst mass or surface area. Results reported for fractional mercury oxidation are strongly influenced by the specific experimental conditions and are therefore difficult to translate from experiment to experiment. The catalyst-normalized results allow for more quantitative analysis of mercury oxidation catalyst data and are the first step in creating a predictive model that will allow for efficient scaling up from laboratory-scale to larger-scale studies.

S. Environmental Protection Agency and various states. A promising method for mercury removal is catalytic oxidation of elemental mercury (Hg super(0)) to oxidized mercury (Hg super(2+)), followed by wet flue gas desulfurization (FGD). FGD cannot remove Hg super(0), but easily removes Hg super(2+) because of its solubility in water. To date, research has focused on three broad catalyst areas: selective catalytic reduction catalysts, carbon-based materials, and metals and metal oxides. We review published results for each type of catalyst and also present a discussion on the possible reaction mechanisms in each case. One of the major sources of uncertainty in understanding catalytic mercury oxidation is a lack of knowledge of the reaction mechanisms and kinetics. Thus, we propose that future research in this area should focus on two major aspects: determining the reaction mechanism and kinetics and searching for more cost-effective catalyst and support materials.

We estimate that total Hg emissions from all anthropogenic sources increased at an average annual rate of 2.9% during the period 1995-2003, reaching 696 ( plus or minus 307) t in 2003, with a speciation split of 395 t of Hg super(0), 230 t of Hg super(2+), and 70 t of Hg super(p). Nonferrous metals smelting and coal combustion continue to be the two leading mercury sources in China, as nonferrous metals production and coal consumption keep increasing. Nonferrous metals smelting and coal combustion together contributed similar to 80% of total Hg emissions during the past decade. Hg emissions from coal combustion increased from 202 t in 1995 to 257 t in 2003 at an average annual rate of 3.0%. Among all of the coal consumption sectors, the power sector is the leading one in Hg emissions growth, up by 5.9% annually. Hg emissions from nonferrous metals smelting increased from 230 t in 1995 to 321 t in 2003 at an average annual rate of 4.2%. Although Hg emissions related to gold smelting decreased since 1996, other nonferrous metals such as zinc, lead, and copper contributed significant Hg growth at annual rates of 8.5%, 13.0%, and 6.9%, respectively. At provincial level, the trends of Hg emissions show significant variation. The uncertainty level decreased from plus or minus 78% (95% confidence interval) in the estimate of total emissions in 1995, to plus or minus 44% in 2003. This is primarily attributed to the decreased emissions from those Hg sources with the largest uncertainty in both activity levels and emission factors, such as artisanal gold smelting, mercury mining, and battery/fluorescent lamp production.

DO - http://dx.doi.org/10.1021/es060406x ER - TY - JOUR T1 - An Overview of Terrestrial Sequestration of Carbon Dioxide: the United States Department of Energy's Fossil Energy R&D Program AN - 19445453; 7066090 AB - Increasing concentrations of CO sub(2) and other greenhouse gases (GHG) in the Earth's atmosphere have the potential to enhance the natural greenhouse effect, which may result in climatic changes. The main anthropogenic contributors to this increase are fossil fuel combustion, land use conversion, and soil cultivation. It is clear that overcoming the challenge of global climate change will require a combination of approaches, including increased energy efficiency, energy conservation, alternative energy sources, and carbon (C) capture and sequestration. The United States Department of Energy (DOE) is sponsoring the development of new technologies that can provide energy and promote economic prosperity while reducing GHG emissions. One option that can contribute to achieving this goal is the capture and sequestration of CO sub(2) in geologic formations. An alternative approach is C sequestration in terrestrial ecosystsems through natural processes. Enhancing such natural pools (known as natural sequestration) can make a significant contribution to CO sub(2) management strategies with the potential to sequester about 290 Tg C/y in U.S. soils. In addition to soils, there is also a large potential for C sequestration in above and belowground biomass in forest ecosystems.A major area of interest to DOE's fossil energy program is reclaimed mined lands, of which there may be 0.63 x 10 super(6) ha in the U.S. These areas are essentially devoid of soil C; therefore, they provide an excellent opportunity to sequester C in both soils and vegetation. Measurement of C in these ecosystems requires the development of new technology and protocols that are accurate and economically viable. Field demonstrations are needed to accurately determine C sequestration potential and to demonstrate the ecological and aesthetic benefits in improved soil and water quality, increased biodiversity, and restored ecosystems.The DOE's research program in natural sequestration highlights fundamental and applied studies, such as the development of measurement, monitoring, and verification technologies and protocols and field tests aimed at developing techniques for maximizing the productivity of hitherto infertile soils and degraded ecosystems.

Although there is no universal agreement on the cause, it is generally understood that global warming is occurring, and many climate scientists believe that this is due, in part, to the buildup of carbon dioxide (CO sub(2)) in the atmosphere. This is evident from the finding presented in the National Academy of Science Report to the President on Climate Change which stated "Greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Temperatures are, in fact, rising. The changes observed over the last several decades are likely mostly due to human activities, ...". In the United States, emissions of CO sub(2) originate mainly from the combustion of fossil fuels for energy production, transportation, and other industrial processes. Roughly one third of U.S. anthropogenic CO sub(2) emissions come from power plants. Reduction of CO sub(2) emissions through sequestration of carbon either in geologic formations or in terrestrial ecosystems can be part of the solution to the problem of global warming. However, a number of steps must be accomplished before sequestration can become a reality. Cost effective capture and separation technology must be developed, tested, and demonstrated; a database of potential sequestration sites must be established; and techniques must be developed to measure, monitor, and verify the sequestered CO sub(2). Geographical differences in fossil fuel use, the industries present, and potential sequestration sinks across the United States dictate the use of a regional approach to address the sequestration of CO sub(2). To accommodate these differences, the DOE has created a nationwide network of seven Regional Carbon Sequestration Partnerships (RCSP) to help determine and implement the carbon sequestration technologies, infrastructure, and regulations most appropriate to promote CO sub(2) sequestration in different regions of the nation. These partnerships currently represent 40 states, three Indian Nations, four Canadian Provinces, and over 200 organizations, including academic institutions, research institutions, coal companies, utilities, equipment manufacturers, forestry and agricultural representatives, state and local governments, non-governmental organizations, and national laboratories. These partnerships are dedicated to developing the necessary infrastructure and validating the carbon sequestration technologies that have emerged from DOE's core R&D and other programs to mitigate emissions of CO sub(2), a potent greenhouse gas. The partnerships provide a critical link to DOE's plans for FutureGen, a highly efficient and technologically sophisticated coal-fired power plant that will produce both hydrogen and electricity with near-zero emissions. Though limited to the situation in the U.S., the paper describes for the international scientific community the approach being taken by the U.S. to prepare for carbon sequestration, should that become necessary.

AN - 36437516; 11826 AB - PURPOSE: The construction and operation of a project designed to demonstrate technology for the production of electricity, steam, and liquid fuels from anthracite coal waste (culm) in Gilberton, Schuykill County of eastern Pennsylvania is proposed. The project has been selected by the Department of Energy for $100 million in cost-sharing funding under the Clean Coal Power Initiative to demonstrate the integration of coal waste gasification and Fisher-Tropsch (F-T) synthesis of liquid hydrocarbon fuels at commercial scale. The proposed facilities would use a gasifier to convert coal waste to synthesis gas, which would get conveyed to F-T liquefaction facilities for production of liquid fuels and to a combined-cycle power plant. For coal gasification, the plant would use Shell technology, which has operated commercial using coal feedstock in The Netherlands since the 1990ss. For liquefaction, the SASOL F-T technology, which has operated commercially in South Africa since the 1980s, would be used. The power plant would use the synthesis gas to drive a gas combustion turbine and exhaust gas from the gas turbine to generate steam from water to drive a steam turbine. Both turbines would generate electricity. The project would be located adjacent to the existing Gilberton Power Plant. The primary feedstock for the facilities would be low-cost anthracite culm, which is locally abundant. In addition to culm, the facility would be capable of using a blend of feedstock containing up to 25 percent petroleum coke, though no petroleum coke would be used during the demonstration period. The facility would produce 5,000 barrels of liquid fuels and 41 megawatts of electricity per day. The area is primarily rural with a mixture of industrial, commercial, and residential land use. Construction of the facilities would begin in early 2006 and continue until mid-2008. The demonstration phase would be conducted from 2008 until mid-2011. If the demonstration were successful, commercial operation would follow immediately. The facility would be designed for a 26-year life. Total cost of the project is estimated at approximately $612 million. POSITIVE IMPACTS: The project would demonstrate the ability for the F-T technology to generate clean, reliable, and affordable electricity for the commercial marketplace. As a result, technical, environmental, and financial data would be generated from the design, construction, and operation of the integrated technologies at a sufficiently large scale to allow industries and utilities to assess the project's potential for commercial application. While individual technologies have been independently operated, this project would demonstrate the integration of technologies that may ultimately reduce the nation's dependence on imported oil. The project could result in the recycling of up to 100 tons of anthracite coal waste dumped in the area and the potential extension of the technology to other areas of the country where culm buildups need attention to address issues related to waste disposal and land reclamation. Over 26 years, 1,000 acres of land would be reclaimed following culm removal. An average of 516 workers would be employed during the construction phase, approximately 250 workers during the demonstration phase, and 150 for long-term operation. NEGATIVE IMPACTS: Construction and operation activities would displace 76.5 acres of deciduous forest habitat, Five 200-foot and one 300-foot stacks would mar visual aesthetics in the area, but these would be shorter than the 326-foot stack at the adjacent Gilberton Power Plant. Plant operation would release sulfur dioxide, nitrogen dioxide, particulate matter, and carbon monoxide; only nitrogen dioxide levels would be significant. Subsidence could affect transfer lines and related facilities in the Mahanoy Creek valley. LEGAL MANDATES: Clean Coal Power Initiative, Fiscal Year 2003.

AN - 68836948; 16311832 AB - Water quality data collected in periodic monitoring programs are often difficult to evaluate, especially if the number of parameters is large, the sampling schedule varies, and values are of different orders of magnitude. The Scatterscore Water Quality Evaluation was developed to yield a quantitative score, based on all measured variables in periodic water quality reports, indicating positive, negative or random change. This new methodology calculates a reconnaissance score based on the differences between up-gradient (control) versus down-gradient (treatment) water quality data sets. All parameters measured over a period of time at two or more sampling points are compared. The relationship between the ranges of measured values and the ratio of the medians for each parameter produces a data point that falls into one of four sections on a scattergram. The number and average values of positive, negative and random change points is used to calculate a Scatterscore that indicates the magnitude and direction of overall change in water quality. The Scatterscore Water Quality Evaluation, a reconnaissance method to track general changes, has been applied to 20 sites at which coal utilization by-products (CUB) were used to control acid mine drainage (AMD).

Coal seams may make excellent candidates for CO (sub 2) sequestration; coal-seam sequestration could enhance methane production and improve sequestration economics. Reservoir-simulation computations are an important component of any engineering design before carbon dioxide is injected underground. We have performed such simulations for a hypothetical pilot-scale project in representative coal seams. In these simulations we assume four horizontal production wells that form a square, that is, two wells drilled at right angles to each other forming two sides of a square, with another pair of horizontal wells similarly drilled to form the other two sides. Four shorter horizontal wells are drilled from a vertical well at the center of the square, forming two straight lines orthogonal to each other. By modifying coal properties, especially sorption rate, we have approximated different types of coals. By varying operational parameters, such as injector length, injection well pressure, time to injection, and production well pressure, we can evaluate different production schemes to determine an optimum for each coal type. Any optimization requires considering a tradeoff between total CO (sub 2) sequestered and the rate of methane production. Values of total CO (sub 2) sequestered and methane produced are presented for multiple coal types and different operational designs.

Put another way, produced water comprises 98 percent of all waste generated by oil and gas exploration and production in the United States. Coalbed natural gas (CBNG) development has been the fastest-growing new source of produced water in recent years. America's production of CBNG grew more than tenfold from 2000 to 2003, to a total of 1.6 trillion cubic feet (TCF) in 2003, about 8.5 percent of domestic natural gas production in that year. The handling, treatment, and disposal of produced water is the single greatest environmental impediment to the nation's oil production, contends the U.S. Department of Energy's National Energy Technology Laboratory (NETL). Concerns over produced water threaten to hobble the growth of the CBNG industry as well.

A "two-dimensional" network of cylindrical pores and parallelepiped connecting throats was constructed and used for the measurements. All pore bodies had the same dimensions, but three-different (square cross- section) pore-throat sizes were randomly distributed throughout the network. An unstructured computational grid for flow through an identical network was developed and used to compute the local pressure gradients and flow vectors for several different (macroscopic) flow rates. Numerical solution results were compared with the experimental data, and good agreement was found. Cross-over from Darcy flow to inertial flow was observed in the computational results, and the permeability and inertia coefficients of the network were estimated. The development of inertial flow was seen as a "two-step" process: (1) recirculation zones appeared in more and more pore bodies as the flow rate was increased, and (2) the strengths of individual recirculation zones increased with flow rate. Because each pore-throat and pore-body dimension is known, in this approach an experimental (and/or computed) local Reynolds number is known for every location in the porous medium at which the velocity has been measured (and/or computed).

To characterize the mining-altered hydrology of this watershed, an airborne reconnaissance was conducted in 2002 using airborne thermal infrared imagery (TIR) and helicopter-mounted electromagnetic (HEM) surveys. TIR uses the temperature differential between surface water and groundwater to locate areas where groundwater emerges at the surface. TIR anomalies located in the survey included seeps and springs, as well as mine discharges. In a follow-up ground investigation, hand-held GPS units were used to locate 103 of the TIR anomalies. Of the sites investigated, 26 correlated with known mine discharges, whereas 27 were previously unknown. Seven known mine discharges previously obscured from TIR imagery were documented. HEM surveys were used to delineate the groundwater table and also to locate mine pools, mine discharges, and groundwater recharge zones. These surveys located 12 source regions and flow paths for acidic, metal-containing (conductive) mine drainage; areas containing acid-generating mine spoil; and areas of groundwater recharge and discharge, as well as identifying potential mine discharges previously obscured from TIR imagery by nondeciduous vegetation. Follow-up ground-based electromagnetic surveys verified the results of the HEM survey. Our study suggests that airborne reconnaissance can make the remediation of large watersheds more efficient by focusing expensive ground surveys on small target areas.

Pennsylvania is reported to have the highest mercury air pollution in the nation, its older coal-fired power plants emitting up to ten times more mercury than newer plants. Rainfall monitored by eight field stations of the Mercury Deposition Network in Pennsylvania have detected regional and seasonal differences in mercury deposition patterns, the highest concentrations measured being ca.124 ng/L total mercury. Calls for increased mercury monitoring activities within the state have come from regional environmental groups concerned with environmental contamination and bioconcentration in fish. Likewise, the potential environmental benefits of reducing mercury emissions from existing power plants cannot be seriously evaluated without extensive environmental monitoring. Low environmental mercury concentrations and the expense of traditional laboratory analyses currently limit such routine and effective monitoring. Microbial biosensors sensitive to mercury have been developed that quantitatively produce light in response to the amount of mercury (II) entering the cells. However, these sensors are often difficult to prepare, can have long lag times between initial mercury exposure and subsequent light emission, and are difficult to use in the field. In this paper, the use of a novel "molecular beacon" sensor for mercury (II) environmental screening is reported. An oligonucleotide sequence is used that changes its conformation upon binding with mercury (II) ions. The change in conformation causes a fluorophore at one end of the oligonucleotide sequence to come in proximity with a specific quencher molecule attached to the other end of the oligonucleotide. Enhanced fluorescence resonance energy transfer (FRET) results in a decrease in the intensity of fluorescence spectrum, which is correlated with the mercury concentration. The fluorescence spectrum generated by this sensor can be analyzed using a field spectrofluorometer, and applications employing fiber optic probes are envisioned. Data are presented that illustrate both the sensitivity of the oligonucleotide sensor under environmental conditions, as well as the potential benefits and shortcomings of this approach.

However, predictions made using many commonly used geochemical models are only reliable if the data and reaction scheme on which they are based are accurate. The extreme pressures and salinities encountered in many aquifers targeted for sequestration make modeling of carbon dioxide sequestration capacities difficult. To provide meaningful predictions, theoretical simulations must be verified against experimental data. In order to test theoretical predictions, carbon dioxide solubility experiments were conducted in a Dickson-type flexible-cell system in pure water and natural brine containing Na-Ca-Mg-K and Cl equivalent to a 20 weight percent NaCl fluid. Experiments were conducted under conditions that bracket the range of temperatures and pressures expected for typical sequestration scenarios. The Dickson-type reaction cell allows for gas-saturated fluid samples to be taken into gas-tight syringes without changing in-situ conditions during sampling. As expected, experimental results indicate a decrease in carbon dioxide solubility in the brine compared to that for pure water at the same temperature and pressure. The experimental results are in good agreement with theoretical predictions provided that equilibrium constants are adjusted to reflect the elevated pressures of the system and appropriate activity-concentration relations are accounted for with elevated salinities. Failure to properly account for elevated pressures and salinities in the theoretical models can result in large errors in solubility estimates. Absence of experimental data on carbonate mineral and carbon dioxide solubility in natural brines under elevated carbon dioxide pressures makes it extremely difficult to verify modeling results, especially when considering rock/water interaction in the subsurface after injection of carbon dioxide. Although experimental results indicate carbon dioxide solubility estimates may be reliable, overall, it is difficult to confidently place quantitative constraints on the ultimate sequestration capacity of deep saline aquifers.

In a concept proposed by Clean Energy Systems, Inc., nitrogen is removed from the combustion air and replaced with steam diluent. In this way, formation of nitrogen oxides is prevented, and the exhaust stream can be separated into concentrated CO2 and water streams. The concentrated CO2 stream could then serve as input to a CO2 sequestration process. In this study, experimental data are reported from a full-scale combustion test using steam as the diluent in oxy-fuel combustion. This combustor represents the 'reheat' combustion system in a steam cycle that uses a high and low-pressure steam expansion. The reheat combustor serves to raise the temperature of the low-pressure steam turbine inlet, similar to the reheat stage of a conventional steam power cycle. Unlike a conventional steam cycle, the reheat enthalpy is actually generated by oxy-fuel combustion in the steam flow. This paper reports on the unique design aspects of this combustor, as well as initial emissions and operating performance. JF - Journal of Engineering for Gas Turbines and Power.

The 5 passive treatment systems sampled in this study are located in the bituminous coal fields of western Pennsylvania and northern Maryland, and treat discharges from Pennsylvanian age coals. The precipitates are dominantly (Co nearly equal Ni>Mn. Cobalt and Ni are preferentially sorbed to Mn oxide phases when these phases are present. As pH increases in the individual CMD treatment systems toward the pH (sub pzc) of goethite, As sorption decreases and transition metal (Co, Mn, Ni and Zn) sorption increases. Sulfate, Na and Fe(II) concentrations may all influence the sorption of trace metals to the Fe hydroxide surface. Results of this study have implications not only for solids disposal and resource recovery but also for the optimization of passive CMD treatment systems.

Effective and reliable monitoring of near-surface environments in the vicinity of these sites is essential to ensure the viability of sequestration activities as well as long-term public and environmental safety. Identification of geologic features (such as faults, fracture zones, and solution enhanced joints that might facilitate release of injected CO (sub 2) back into the atmosphere) is a key step in this process. This study reports on near-surface geologic and geophysical characterization efforts conducted at the Department of Energy National Energy Technology Laboratory (NETL) West Pearl Queen carbon sequestration pilot site in southeastern New Mexico, USA, and their use for uncovering possible mechanisms associated with escape of small amounts of perfluorocarbon tracers injected with the CO (sub 2) .

Other geologic formations, such as depleted petroleum reservoirs, deep saline aquifers and others have received considerable attention as sites for sequestering CO (sub 2) . This review focuses on geologic sequestration of CO (sub 2) in unmineable coalbeds as the geologic host. Key issues for geologic sequestration include potential storage capacity, the storage integrity of the geologic host, and the chemical and physical processes initiated by the deep underground injection of CO (sub 2) . The review topics include (i) the estimated CO (sub 2) storage capacity of coal, along with the estimated amount and composition of coalbed gas; (ii) an evaluation of the coal seam properties relevant to CO (sub 2) sequestration, such as density, surface area, porosity, diffusion, permeability, transport, rank, adsorption/desorption, shrinkage/swelling, and thermochemical reactions; and (iii) a treatment of how coalbed methane (CBM) recovery and CO (sub 2) -enhanced coalbed methane (ECBM) recovery are performed (in addition, the use of adsorption/desorption isotherms, injection well characterization, and gas injection are described, as well as reservoir screening criteria and field tests operating in the United States and abroad); (iv) leak detection using direct measurements, chemical tracers, and seismic monitoring; (v) economic considerations using CO (sub 2) injection, flue gas injection, and predictive tools for CO (sub 2) capture/sequestration decisions; (vi) environmental safety and health (ES&H) aspects of CO (sub 2) -enhanced coalbed methane/sequestration, hydrodynamic flow through the coal seam, accurate gas inventory, ES&H aspects of produced water and practices relative to ECBM recovery/sequestration; (vii) an initial set of working hypotheses concerning the chemical, physical, and thermodynamic events initiated when CO (sub 2) is injected into a coalbed; and (viii) a discussion of gaps in our knowledge base that will require further research and development. Further development is clearly required to improve the technology and economics while decreasing the risks and hazards of sequestration technology. These concerns include leakage to the surface, induced seismic activity, and long-term monitoring to verify the storage integrity. However, these concerns should not overshadow the major advances of an emerging greenhouse gas control technology that are reviewed in this paper.

For more than two decades, significant quantities of gas sorbed in coal seams have been collected as a relatively environmentally friendly fossil fuel energy resource. Laboratory experiments have shown that coals preferentially sorb carbon dioxide. Thus, concomitant enhanced coal bed methane production and carbon dioxide sequestration in unminable coal seams is a promising technology being developed as a win-win process to reduce global warming and produce a valuable energy resource. However, because CO sub(2) will not reach all portions of the seam, not all of the in situ methane will be produced and not all of the "theoretical" sequestration capacity will be utilized. For sequestration, the amount of carbon dioxide that could be stored in the coal seam was found to be between 50% and 70% of the thermodynamic limit. The fraction of methane produced was much higher, between 80% and 97%. Reservoir simulations were used to predict how the well pattern and operating conditions can be modified to maximize the amounts of CO sub(2) stored and CH sub(4) recovered. For this study, we used the PSU-COALCOMP compositional coal bed methane reservoir simulator and measured sorption isotherms to predict the maximum amount of carbon dioxide that could be sequestered in a coal seam and show how coal seam characteristics and injection practices will reduce the actual amount sequestered.

AN - 67389763; 15681382 AB - Metal membranes play a vital role in hydrogen purification. Defect-free membranes can exhibit effectively infinite selectivity but must also provide high fluxes, resistance to poisoning, long operational lifetimes, and low cost. Alloying offers one route to improve on membranes based on pure metals such as palladium. We show how ab initio calculations and coarse-grained modeling can accurately predict hydrogen fluxes through binary alloy membranes as functions of alloy composition, temperature, and pressure. Our approach, which requires no experimental input apart from knowledge of bulk crystal structures, is demonstrated for palladium-copper alloys, which show nontrivial behavior due to the existence of face-centered cubic and body-centered cubic crystal structures and have the potential to resist sulfur poisoning. The accuracy of our approach is examined by a comparison with extensive experiments using thick foils at elevated temperatures. Our experiments also demonstrate the ability of these membranes to resist poisoning by hydrogen sulfide. JF - Science (New York, N.Y.)

Nineteen cations occurred to some extent in both phases. Using a column leaching method, the release of the metals was determined with four leachant solutions; the pH of the leachants ranged between 1.2 and 12. Although the amount of an element extracted from the fly ash was low, solubility in alkaline leachants was correlated with elements in non-silicate compounds. Solubility in acid solutions was correlated more strongly with silicate phase concentration.

PM2.5 measurements had also been obtained with TEOM monitors located in the Pittsburgh, PA, area, and at sites in Ohio, including Steubenville, Columbus, and Athens. The PM data from all these sites were analyzed on high PM days; PM2.5 TEOM particulate mass at all sites was generally associated with transitions from locally high barometric pressure to lower pressure. Elevated concentrations occurred with transport of PM from outside the local region in advance of frontal passages as the local pressure decreased. During highpressure periods, concentrations at the study sites were generally low throughout the study region. Further details related to this transport were obtained from surface weather maps and estimated back-trajectories using the hybrid single-particle Lagrangian integrated trajectory model associated with these time periods. These analyses indicated that transport of pollutants to the Pittsburgh site was generally from the west to the southwest. These results suggest that the Ohio River Valley and possible regions beyond act as a significant source of PM and its precursors in the Pittsburgh area and at the other regional sites included in this study.

The stream bounds the pit of the Deep Creek limestone quarry, operated by Keystone Lime Company. During low flow, the stream abruptly terminates in a swallet, leaving approximately 100 m of dry streambed. In addition to geophysically investigating this swallet, our study located two other zones of loss active during periods of higher flow. Multiple resistivity profiles using the SuperStingT Resistivity System were generated along the zone of stream loss and compared with results of ground penetrating radar (GPR) and electromagnetic conductivity (EM) profiles in the same location. Dye trace using FluoresceinT confirmed the flow path of water from the stream into the quarry. Geologic examination of the area reveals several sizable known caves developed in the same limestone sequence; however, there are no known cave entrances in the immediate vicinity. Our study shows that surface geophysics coupled with hydrologic and geologic analysis can locate possible flow paths for groundwater in a karst aquifer, even in the absence of obvious karst surface expression. Borehole confirmation is slated before remediation measures are executed.

A slurry composed of CO (sub 2) particles in liquid N (sub 2) at a temperature of -180 degrees C, when injected into heated zones, absorbs heat. Conversion of the slurry to a gas creates a cold pressure front that forces heated combustion gases out of the bank. The waste bank had been burning for approximately 30 years. The 5000-m (super 2) (1.2 acre) site was characterized by a three-dimensional array of temperature measuring points. Temperatures were measured over a 30-month period, before during and after two tests of cryogenic injection. The amount of cryogenic slurry injected was insufficient to completely extinguish the fire, but evaluation of the temperature profiles indicated that it had cooled localized hot spots and promoted ambient cooling of the more widely disbursed heated areas within the bank.

In this method, a characteristic fire signature is based on the ratio of higher molecular weight hydrocarbon gases (C (sub 2) to C (sub 5) ) to total hydrocarbon gas. Initially, gas samples are obtained at the bottom of boreholes under baseline or static conditions. A second set of samples is obtained when a suction fan is used to influence the direction of gas movement. Pressure data define the degree of communication between boreholes. The value of the diagnostic ratio under communication conditions is taken as a measure of subsurface fire activity related to a particular flow direction. Using a Venn diagram technique, the results are mapped as quadrants on a borehole map of the site. Repetition of the communication tests provides overlapping quadrants that define hot, cold, and indeterminate areas. The MFD has been used to distinguish hearted and cold subsurface areas at four mine fire sites. At each of the sites, the extent of the fire could not be inferred from surface evidence, and the location of combustion zones had a significant impact on plans to control the fire. Although the method is labor intensive and requires drilling cased boreholes, it is relatively simple and provides information that cannot be obtained by other methods.

Up to 625 plants, representing similar to 44% of the nameplate capacity of all coal-fired plants, could switch. If all switched, more than $8.8 billion additional capital would be required and the cost of electricity would increase by up to $5.9 billion per year, depending on levels of plant derating. Coal switching would result in sulfur dioxide (SO2) emissions reduction of 4.5 million t/yr. Increase in cost of electricity would be in the range of 0.31-0.73 cents per kilowatthour. Average cost of S emissions reduction could be as high as $1298 per t of SO2. Up to 367 plants, or 59% of selected plants with 32% of 44% nameplate capacity, could have marginal cost in excess of $1000 per t of SO2. Up to 73 plants would appear to benefit from both a lowering of the annual cost and a lowering of SO2 emissions by switching to the PRB coal.

It has funded the development of tubular solid oxide fuel cell (SOFC) and molten carbonate fuel cell (MCFC) power systems operating at up to 60% efficiency on natural gas. The remarkable environmental performance of these fuel cells makes them likely candidates to help mitigate pollution. DOE is now pursuing more widely applicable solid oxide fuel cells for 2010 and beyond. DOE estimates that a 5 kW solid oxide fuel cell system can reach $400 per kW at reasonable manufacturing volumes. SECA-the Solid State Energy Conversion Alliance - was formed by the National Energy Technology Laboratory (NETL) and the Pacific Northwest National Laboratory (PNNL) to accelerate the commercial readiness of planar and other solid oxide fuel cell systems utilizing 3-10 kW size modules by taking advantage of the projected economies of production from a "mass customization" approach. In addition, if the modular 3-10 kW size units can be "ganged" or "scaled-up" to larger sizes with no increase in cost, then commercial, microgrid, and other distributed generation markets will become attainable. Further scale-up and hybridization of SECA SOFCs with gas turbines could result in penetration of the bulk power market. This paper reviews the current status of the solid oxide and molten carbonate fuel cells in the U.S. JF - Journal of Power Sources AU - Williams, M C AU - Strakey, J P AU - Singhal, S C AD - National Energy Technology Laboratory, U.S. Department of Energy, Morgantown, WV, USA Y1 - 2004/05// PY - 2004 DA - May 2004 SP - 79 EP - 85 VL - 131 IS - 1-2 SN - 0378-7753, 0378-7753 KW - Pollution Abstracts KW - Fuel technology KW - Gas turbines KW - Electric power generation KW - Reviews KW - Economics KW - Pollution effects KW - Natural gas KW - INE, USA, Pacific Northwest KW - high temperature KW - P 0000:AIR POLLUTION UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/19447447?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Apollution&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Power+Sources&rft.atitle=U.S.+distributed+generation+fuel+cell+program&rft.au=Williams%2C+M+C%3BStrakey%2C+J+P%3BSinghal%2C+S+C&rft.aulast=Williams&rft.aufirst=M&rft.date=2004-05-01&rft.volume=131&rft.issue=1-2&rft.spage=79&rft.isbn=&rft.btitle=&rft.title=Journal+of+Power+Sources&rft.issn=03787753&rft_id=info:doi/10.1016%2Fj.jpowsour.2004.01.021 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2006-12-01 N1 - Last updated - 2015-03-25 N1 - SubjectsTermNotLitGenreText - Fuel technology; Gas turbines; Reviews; Electric power generation; Economics; Pollution effects; Natural gas; high temperature; INE, USA, Pacific Northwest DO - http://dx.doi.org/10.1016/j.jpowsour.2004.01.021 ER - TY - JOUR T1 - Use of poly(lactic acid) amendments to promote the bacterial fixation of metals in zinc smelter tailings AN - 19923868; 5793467 AB - The ability of poly(lactic acid) (PLA) to serve as a long-term source of lactic acid for bacterial sulfate reduction activity in zinc smelter tailings was investigated. Solid PLA polymers mixed in water hydrolyzed abiotically to release lactic acid into solution over an extended period of time. The addition of both PLA and gypsum was required for indigenous bacteria to lower redox potential, raise pH, and stimulate sulfate reduction activity in highly oxidized smelter tailings after one year of treatment. Bioavailable cadmium, copper, lead and zinc were all lowered significantly in PLA/gypsum treated soil, but PLA amendments alone increased the bioavailability of lead, nickel and zinc. Similar PLA amendments may be useful in constructed wetlands and reactive barrier walls for the passive treatment of mine drainage, where enhanced rates of bacterial sulfate reduction are desirable.

Effective modeling of sequestration scenarios and accurate prediction of sequestration capacities rely on adsorption isotherms to provide relationships between pressure and adsorbed-amount at various temperatures. Investigations at NETL have attempted to provide information about the reliability of these measurements, insight into factors affecting the adsorption capacity, and information about the chemistry/mechanism of the adsorption phenomenon. These studies have included an inter-laboratory comparison of adsorption isotherm reproducibility; the derivation of an adsorption isotherm equation which accounts for the volume effects which may occur when an adsorbate alters the structure of an adsorbent such as is observed when the coal organic matrix swells in the presence of adsorbing gases; an examination of the effects of rank, moisture content, and temperature on the adsorption capacity; and spectroscopic investigations into the nature of the coal-CO (sub 2) interaction(s).

NETL accomplishes this goal through the development of advanced technologies capable of expanding the size and recoverability of the nation's gas resource. Critical to this R&D effort is an understanding of the remaining gas resource base, particularly that resource that exists at and beyond the current margins of technical and economic recoverability. This particular need results in the application of a unique resource assessment method designed to capture the dynamics of resource recoverability under a variety of alternative technology, cost, and policy futures. NETL's assessments begin with a description of the remaining gas-in-place through analysis of thousands of geophysical well logs. Production records and remote sensing data are used to estimate the regional potential for fracture-related permeability enhancement. Computer models then predict the unique response of each of thousands of individual resource "packets" to potential changes in drilling costs, taxation, and other factors. Phase I, completed in February, 2003, estimated that roughly 4,700 tcf of gas exists in-place in selected formations of the Greater Green River and Wind River basins of Wyoming. Initial model results indicated that approximately 97% of that resource is currently not economically-recoverable, but noted that significant expansion in recoverability was possible with foreseeable technology advance. A second phase of this effort, focusing on the Anadarko basin of Oklahoma and the Uinta basin of Utah will be completed in 2004.

Helicopter electromagnetic (HEM) surveys are being used to map the distribution of produced water around impoundments. Results of these surveys can be grouped into three different categories: 1) areas where the produced water is more conductive than the shallow groundwater and HEM surveys can easily discern the plume of infiltrating produced water; 2) areas where the produced water exhibits the same conductivity as natural groundwater and the plume cannot be detected (in this case, the produced water is not degrading the native groundwater and is not of concern); and 3) areas where the produced water is less conductive than natural groundwater and the produced water has diluted the solutes and improved the quality of the native groundwater. Examples of all three categories have been identified. Such knowledge will allow impoundments to be designed better and will facilitate the intelligent use of produced water. Based on the data, it appears that this technique will prove to be useful to land use planners, natural gas producing companies, and state regulatory personnel.

The resulting amine-enriched silicon sorbent (SBA-15) has been proven to be competitive with existing environmental CO2 controlled life sorbents based on the immobilised amine technology. XPS analysis has indicated that the amine groups (N1s Peak) were incorporated onto the surfaces of this amine-based sorbent in the range of 7%. The performance of the SBA-15 was comparable to the commercially available immobilised amine sorbent (IAS).

Large stationary sources that include coal-based electric generating stations are plausible targets for the removal of CO sub(2). Chemical absorption of CO sub(2) is viewed as one option that could be applicable for its separation from both fuel gas and flue gas streams. Processes based on solid regenerable sorbents that efficiently absorb CO sub(2) and release it in concentrated form have the potential to be cost-effective relative to solvent-based practices. This communication summarises a preliminary investigation exploring the reaction of CO sub(2) with a number of calcium-based sorbents using a thermogravimetric (TG) analyser. Upon reaction at high temperature with pure CO sub(2), these materials are converted into metal carbonates. Thermal regeneration of the sorbents was accomplished upon heating spent materials to higher temperature in a nitrogen stream. TG studies show the absorption reaction for Ca-based materials was initially rapid and then entered into a slower kinetic regime. Multi-cycle testing conducted within the TG analyser indicated sorbents could be regenerated and reused. Theoretical conversions ranging from 50-75% were observed for the calcium/zirconia sorbents in comparison to 15-20% for the calcium/lanthanum-doped alumina sorbent. Improved conversion was attributed to the pore size differential between mesoporous zirconia and microporous lanthanum-alumina. TG studies performed at 500 degree C with lithium zirconate show that the rate of CO sub(2) absorption was continuous with time on stream. Under nitrogen, rapid regeneration of the lithium carbonate product occurred at temperatures greater than 700kzC.

S. Department of Energy AN - 51843726; 2004-040934 AB - The National Energy Technology Laboratory (NETL) of the U.S. Department of Energy (DOE) has assembled a group of scientists and engineers from the staff to provide time and technical knowledge for K-12 Western Pennsylvania and West Virginia school districts. These volunteers act as resources for laboratory visits and classroom lectures/demonstrations. NETL sponsors ten high school or middle school teachers to serve as paid interns during the summer months at either the Pittsburgh or Morgantown site. They assist a scientist or engineer with an on-going research projects and incorporate the experience into their lesson plans. Both laboratory sites host a regional High School Science Bowl where the respective team winners compete against some 50 other regional team winners at the DOE National Science Bowl held in Washington, D.C., each year. Questions are taken from the fields of science, mathematics and computer science. The Energy, Environment and Economics (EEE) Seminar is organized yearly for K-6 teachers. The seminar is a two-day workshop, consisting of hands-on activities, conducted by NETL personnel, university professors and local science organizations/museums. Site tours are scheduled throughout the school year to provide K-12 students the opportunity to observe and interact with researchers on how a variety of science experiments are being conducted. School classroom presentations are also a major activity of NETL personnel for K-12 students. These presentations include hands-on activities in all fields of science, engineering and computer applications. NETL also participates in the National Earth Day by sponsoring a poster contest for K-5 students. Three winning posters are selected from each grade and displayed at the site. The NETL website (www.netl.doe/cool science/index.html) serves as the main source of communication with the educational community. Details of the above programs and other educational outreach activities sponsored by NETL can be found on this website.

Roughly one third of the carbon emissions in the United States comes from power plants. Since electric generation is expected to grow and fossil fuels will continue to be the dominant fuel source, there is growing recognition that the energy industry can be part of the solution to reducing greenhouse gas emissions by capturing and permanently sequestering CO sub(2). Consequently, an important component of the United States Department of Energy's (DOE) research and development program is dedicated to reducing CO sub(2) emissions from power plants by developing technologies for capturing CO sub(2) and for subsequent utilization and/or sequestration. Injection of CO sub(2) into geologic formations is being practiced today by the petroleum industry for enhanced oil recovery, but it is not yet possible to predict with confidence storage volumes, formation integrity and permanence over long time periods. Many important issues dealing with geologic storage, monitoring and verification of fluids (including CO sub(2)) in underground oil and gas reservoirs, coal beds and saline formations must be addressed. Field demonstrations are needed to confirm practical considerations, such as economics, safety, stability, permanence and public acceptance. This paper presents an overview of DOE's research program in the area of CO sub(2) sequestration and storage in geologic formations and specifically addresses the status of new knowledge, improved tools and enhanced technology for cost optimization, monitoring, modeling and capacity estimation. This paper also highlights those fundamental and applied studies, including field tests, sponsored by DOE that are measuring the degree to which CO sub(2) can be injected and remain safely and permanently sequestered in geologic formations while concurrently assuring no adverse long term ecological impacts.

Researchers at the Department of Energy's National Energy Technology Laboratory (DOE/NETL) have conducted a long-term column leaching study of 32 Class F fly ash samples from pulverized coal (PC) combustion, and quantified the release of 19 cations in four leachants with a pH between 1.2 and 12. The relative solubility (M sub(L/T)) of each cation was defined as the total mass leached (M sub(L)) relative to the concentration (M sub(T)) of that element in the fly ash sample. A frequency distribution of relative solubility values was computed with ranges defined as insoluble, slightly soluble, moderately soluble, and very soluble. On the basis of this sample set, Ba, Cd, Fe, Pb, Sb, and Se in PC fly ash are insoluble. The elements Al, Be, Ca, Co, Cr, Cu, K, Mg, Mn, Na, Ni, and Zn are slightly to moderately acid soluble. Only Ca and Na are water soluble; As and Ca are soluble in the basic solution. The results of this study indicate that the extent to which cations in Class F PC fly ash can be leached by naturally occurring fluids is very limited.

Frequency domain electromagnetics (FDEM) and thermal infrared (TIR) imagery are being used to map surface and subsurface hydrologic features. FDEM is being used to map water-filled fractures and voids that serve as groundwater conduits; TIR is being used to identify locations where groundwater discharges to the surface. The benefits of airborne reconnaissance include: significant cost savings through large-scale data collection, reduced landowner-access issues, improved watershed management practices, efficient targeting of costly, high resolution ground investigations, and superior techniques for locating drilling sites. The papers that follow this overview provide detailed descriptions of the application of these technologies on a case study basis. JF - Mine Water and the Environment AU - Ackman, Terry E AD - U. S.

Airborne magnetic and electromagnetic conductivity surveys were conducted over a 12.3 km super(2) (4.75 mi super(2)) area that included the Oaks Arm of Clear Lake and the old mine. These surveys identified four magnetic and/or conductive anomalies that may represent groundwater conduits towards or away from the Herman Impoundment. An anomaly that extended from Herman Impoundment through a waste rock dam and into Clear Lake was selected for a more detailed ground electromagnetic conductivity survey. The combined results of the airborne and ground surveys provided a detailed, lateral depiction of conductive zones, the most probable pathways for groundwater flow. These surveys also identified near-surface areas that may contain elevated concentrations of sulfide minerals that weather to produce acid groundwater.

It is a global problem that will need to be solved on a global level. The link between anthropogenic emissions of CO sub(2) with increased atmospheric CO sub(2) levels and, in turn, with increased global temperatures has been well established and accepted by the world. International organizations such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Intergovernmental Panel on Climate Change (IPCC) have been formed to address this issue. Three options are being explored to stabilize atmospheric levels of greenhouse gases (GHGs) and global temperatures without severely and negatively impacting standard of living: (1) increasing energy efficiency, (2) switching to less carbon-intensive sources of energy, and (3) carbon sequestration. To be successful, all three options must be used in concert. The third option is the subject of this review. Specifically, this review will cover the capture and geologic sequestration of CO sub(2) generated from large point sources, namely fossil-fuel-fired power gasification plants. Sequestration of CO sub(2) in geological formations is necessary to meet the President's Global Climate Change Initiative target of an 18% reduction in GHG intensity by 2012. Further, the best strategy to stabilize the atmospheric concentration of CO sub(2) results from a multifaceted approach where sequestration of CO sub(2) into geological formations is combined with increased efficiency in electric power generation and utilization, increased conservation, increased use of lower carbon-intensity fuels, and increased use of nuclear energy and renewables.

Geological sequestration of carbon dioxide has been proposed as one means of reducing these contributions. Unmineable coalseams are good candidates for such sequestration projects because they have served as excellent storage reservoirs for sorbed gases for geological time periods. Additionally, the enhanced methane production from these reservoirs makes a favorable contribution to the economics of the projects. This study examines the design considerations for a proposed carbon dioxide sequestration/enhanced coalbed methane pilot project. The project consists of an isolated 3000 ft square pattern. The pattern is formed by four 3000 ft long horizontal wellbores on the exterior of the square that serve as production wells. At the center of the pattern are four horizontal wellbores that serve as either producers or injectors. The central wellbores are oriented perpendicular to the exterior wellbores. Methane production occurs through all wellbores until the reservoir pressure is reduced to given value, at which time the central wellbores are converted to carbon dioxide injectors while the exterior wellbores continue methane production. In this work we consider the effects of various injector lengths and operating pressures on the performance of the project. On the bases of the ultimate amount of carbon dioxide sequestered, central injectors of approximately 600 feet are found to be optimum. However, this length for the injectors does not represent the highest injection rate of carbon dioxide, nor does it correspond to the largest amount of methane recovered. This paper examines the trade offs involved for injector lengths between 300 ft and 1000 ft and injection pressures from approximately 50% to 100% of the initial reservoir pressure. The effects of sweep efficiency and concentration profiles are analyzed for their contribution to project performance.

The objective of the screening study was to evaluate and rank potential sites and geologic strata to select a site for a small-scale pilot. Producing and depleted gas reservoirs, and saline aquifers were considered. Computer simulation is an important design tool and virtually all reservoir development decisions consider simulation results. Consequently, simulations were performed for CO (sub 2) -well injectivity optimization, for brine and gas production, and for a variety of reservoir characteristics and operational parameters that could be useful for maximizing sequestration capacity. Simulations were run with a compositional simulator for saline aquifers and depleted gas reservoirs with high water saturation. Both vertical and horizontal injector wells were considered. For the saline aquifer case, a two-dimensional vertical cross section of the reservoir was modeled with a stochastic permeability field due to the lack of information about permeability heterogeneity. CO (sub 2) propagation and breakthrough, pressure distribution, and saturation of different phases were visualized. The computations show that injectivity is very sensitive to absolute permeability and formation thickness. An inverted 5-spot well pattern was used as a pilot test model for the depleted gas reservoir case. The base well-pattern consisted of one vertical or horizontal well in the center of the square and vertical producers in the four corners. Reservoir properties such as permeability, porosity, brine saturation, and degree of anisotropy were modified to approximate different types of gas reservoirs. Variation of operational parameters such as well completions, well length, injection and production well pressure were used to evaluate injection and production plans for each reservoir type. The findings of this study will be useful in selecting carbon sequestration pilot sites, and evaluating potential sequestration efficiencies and enhanced natural gas production.

CO (sub 2) will be injected into the Upper Freeport coal, which lies approximately 1400 feet beneath the surface in Marshall County, West Virginia. The objectives of the pilot test are to enhance coal bed methane production through CO (sub 2) injection and, at the same time, to sequester significant amounts of injected CO (sub 2) . Effective sequestration requires that injected CO (sub 2) remain trapped for several thousand years; thus, assessment of reservoir integrity is a critical component of the sequestration effort. As part of the site assessment we examined subsurface well data and various satellite images, digital elevation data, and aerial photographs to characterize site geology and provide a preliminary assessment of the integrity of the sequestration interval. Bedding dip in the area is less than 1 degree. The pod-like distribution of the coal in this area makes it unminable. This reconnaissance effort incorporated a comprehensive lineament analysis to identify potential fracture zones or faults in the area. Lineament orientations are clustered into orthogonal strike and dip sets with two additional sets forming an acute angle in the dip direction. Lineament orientations are also consistent with surface fracture and coal cleat trends mapped in the area. Lineaments mapped in the vicinity of the pilot site are dominated by a N75E (shear) trend. The association of lineaments with actual fracture zones or faults will be confirmed in future electromagnetic conductivity and seismic surveys of the pilot site. The combined remote sensing and geophysical studies are intended to determine whether relatively high permeability pathways exist along which displaced methane or injected CO (sub 2) might migrate to the surface. Geochemical monitoring activities will be concentrated near likely pathways is confirmed.

Roughly one-third of all the United States' carbon emissions come from power plants. Since electricity generation is expected to grow, and fossil fuels will continue to be the dominant fuel source, power generation can be expected to provide even greater CO sub(2) contributions in the future. Consequently, an important component of the United States Department of Energy's (DOE's) research and development program is dedicated to reducing CO sub(2) emissions from power plants by developing technologies to capture CO sub(2) for utilization and/or sequestration. A primary goal of this research is to develop technology options that dramatically lower the cost of eliminating CO sub(2) from flue gas and other streams by use of either pre- or post-combustion processes. This research is in its early stages, and is exploring a wide range of approaches, including membranes, improved CO sub(2) sorbents, advanced scrubbing, oxyfuel combustors, formation of CO sub(2) hydrates, and economic assessments. This paper presents an overview of the DOE research program in the area of CO sub(2) separation and capture, while specifically addressing the status of research efforts related to promising pathways and potential technological breakthroughs.

This departure is traced to its corrugated terrain. The more typical random terrain of the lower Cheat River network obeys the standard scaling laws. We modify the random network model of Scheidegger to include the effects of topography, reproducing the behavior observed in the Cheat River basin.

However, technology developed by these industries, geophysical technology in particular, is probably the best way to find out the source of the problem-an unavoidable first step for any clean-up efforts to have a chance of success.

Critical experimental data, however, are still lacking in the PTX range relevant to CO (sub 2) sequestration in deep saline aquifers. Considerable uncertainties also exist when the complexities of multi-component salinity are considered. A large number of additional uncertainties are associated with the heterogeneous reactions which may occur in deep aquifers upon CO (sub 2) injection, especially in the area of reaction kinetics. An ongoing project at the National Energy Technology Laboratory (NETL) focuses on the complex solution chemistry of CO (sub 2) in brines and the special types of analyses required to study their kinetics, and on the carbonate and silicate mineral formation/dissolution reactions which may be important in geologic sequestration in deep saline aquifers. The facilities to conduct hydrothermal CO (sub 2) -water-rock reactions and analyze these complex mixtures have been developed at NETL. In order to study the reaction kinetics of these systems, rapid analysis of meta-stable solutions may be required in addition to standard analytical methods and techniques. The rocking autoclave for the hydrothermal reactions and each of the key instruments for characterization of the brines, mineral components, and reaction products will be described. Experimental results from this investigation will be integrated with geochemical modeling studies and field studies.

Injection of carbon dioxide into saline aquifer formations is one option in geologic sequestration of carbon dioxide. The estimated carbon storage capacity of saline formations in the United States is large, making them a viable long-term solution. Carbon dioxide can be trapped in saline aquifers via mineral trapping. Various carbonates such as calcite, dolomite, and siderite can be formed in the brine aquifer by mineral trapping. The extended time, however, required for mineral trapping is the major concern of this process. In this study, accelerated mineral trapping experiments with brine solutions under controlled conditions have been initiated. Brine solutions were tested in a half-liter autoclave under various conditions. Preliminary results indicate that the mineral species type and amount of solid precipitation depend on the pH of the brine and the reaction conditions utilized. In addition, the reactions were modeled with an advanced geo-chemical code. The computer simulation includes all the possible chemical reactions for the formation of carbonates and various reaction parameters including temperature, pressure, ionic concentration, and pH. The combined experimental and modeling data suggest that pH plays a key role in the formation of carbonate minerals. The effects of temperature and carbon dioxide pressure have less impact on the formation of carbonates.

A significant new storage technique involves scrubbing or removal of CO2 from the flue gases of fossil fuel power plants and injection into underground geologic formations, thus sequestering or preventing its addition to the atmosphere. Ideally, geologic sequestration would result in mineral trapping, the process of forming in-situ, interstitial carbonate minerals from CO2 and the host rock and formation waters. To address the potential of brine aquifers as mineral trapping horizons, a number of published oil and gas well brine composition data bases were evaluated for the Oriskany Formation, Mt. Simon Formation and the Williston Basin. There was considerable variation in the number of chemical variables that were tabulated for the respective wells. To evaluate the variability of the ionic concentrations and pH among the data, a one-way analysis of variance model (ANOVA) was computed (p = 0.05) for each formation. Although there are significant differences among the carbonate forming metal ions, the brine chemistry of the three aquifers shows that the units have the potential to sequester anthropogenic CO2. A limiting factor for the carbonation reaction however may be the acidic nature of some of the brines.

Thus, coalbed sequestration is a promising candidate for early commercialization; both reservoir simulations and identification of the most-needed laboratory and field research measurements are needed now. In the implementation of new technologies for underground injection of fluids, field-scale reservoir simulators traditionally are used in the design of pilot and demonstration projects. However, they also may be used to perform sensitivity studies and to help identify those chemical, geophysical, flow, and other measurements that are most-needed for optimization of the new technology. We have performed parametric studies of the effects of various (uncontrollable) coal-seam properties and (controllable) engineering parameters on carbon dioxide sequestration. These properties include porosity, permeability, cleat spacing, pod size, sorption isotherm, sorption rate, and reservoir pressure, water saturation, and gas composition. Engineering parameters explored include various combinations of vertical and horizontal wells, and well lengths and orientations. These results may contribute not only to site selection and design of operating conditions, but to choice and interpretation of both field measurements (such as well-test measurements of permeability) and laboratory measurements (such as the effects of confining pressure on sorption isotherms, flow through cleats, and coal swelling). The results may also help to guide the development of advanced simulators that include such features as explicit cleats (instead of dual porosity) or advanced gridding methods.

However, there are several issues that need to be studied before this option can become economically and socially acceptable. A few of these key issues include the underground storage time, the changes in a formation's porosity and permeability induced by CO (sub 2) injection, and the ultimate fate of the injected CO (sub 2) . These issues are all affected by the chemical interaction between the brine, the injected CO (sub 2) , and the mineral content of the aquifer. In the current study a one-dimensional reactive transport model was developed using the PHREEQC geochemical modeling code to predict the long-term chemical behavior of a deep saline aquifer after CO (sub 2) injection. The model predicts the emergence of four well-defined reaction fronts, each characterized by the total dissolution of a mineral species and the sudden drop in pH level of the solution. These fronts emerge as a result of stepwise mineral buffering reactions, which stabilize the pH within the regions between reaction fronts. The results also indicate that the transport of carbon is significantly retarded with respect to the flow of the brine itself. This is due to the precipitation of carbonate minerals (mainly siderite). This precipitation of carbonates is of particular interest since it may lead to permanent storage of carbon in a stable, solid form.

PM sub(2.5) composition was also determined. These data are part of an ongoing PM sub(2.5) characterization program centered around a sampling site at the National Energy Technology Laboratory Pittsburgh campus. The composition and concentrations of PM sub(2.5) were both highly variable during this time period. Likely sources of PM sub(2.5) during low concentration periods were transportation, coal-fired boiler, and other emissions generated in the local area. For these periods, the average concentration of PM sub(2.5) was 13 mu g/m super(3) and 70% of the PM sub(2.5) mass was carbonaceous material, including semivolatile organic material that was lost in varying degrees from both the TEOM and FRM samplers. In contrast, much higher concentrations of PM sub(2.5) were associated with transport of pollutants to the site. Analysis of meteorological and back-trajectory data suggests that these pollutants were emitted elsewhere during a period of high atmospheric pressure and were subsequently transported to the site with the passage of a frontal system. When the PM sub(2.5) collected at the site originated from the west or southwest, the concentrations averaged 31 mu g/m super(3) and ammonium sulfate averaged 54% of the PM sub(2.5) mass. Scanning election microscopy and trace element analyses are consistent with the association of high concentration PM sub(2.5) episodes with transport of coke and iron processing, coal-fired boiler, and other emissions from the Ohio River Valley region to the NETL site. Preliminary observations on the use of SEM and PIXE data in source apportionment at the NETL site are given.

AN - 52130266; 2002-024089 AB - The U. S. Geological Survey, in cooperation with the U. S. Department of Energy, is reevaluating the resource potential of selected basin-centered gas accumulations in the United States in order to accommodate changing geologic perceptions since completion of the USGS 1995 National Petroleum Assessment. In 1995 the USGS assessed one basin-centered gas play and three conventional plays within the trend of Jurassic and Cretaceous Cotton Valley Group fluvial-deltaic sandstones across the onshore northern Gulf of Mexico Basin. Evaluation of geologic and production data provides new insights into these Cotton Valley plays. Data favorable and unfavorable for the presence of continuous-type basin-centered gas accumulations are summarized. JF - U. S.

The Innovations for Existing Plants (formerly the Advanced Research and Environmental Technologies) programme, managed by the National Energy Technology Laboratory (NETL), develops advanced environmental control technologies for coalbased power systems. The programme also provides high-quality scientific information on present and emerging environmental issues for use in regulatory and policy decision-making. An important component of the programme is the research and development of advanced nitrogen oxide (NOx) control technologies. This effort is focused primarily on systems capable of controlling NOx emissions to a level at or below 0.15 lb/million Btuat a cost significantly lower than state-of-the-art technology. The programme will also provide an improved understanding of the impact of these advanced technologies on related issues such as unburned carbon, waterwall wastage, and mercury speciation and capture. The research is driven by continuing pressure for further reductions in NOx emissions from coal-fired utility boilers to address ground-level ozone and other environmental considerations including ambient fine particulates, visibility, eutrophication, and climate change. NETL is currently managing a portfolio of NOx control technology R&D projects ranging from laboratory studies to modelling to full-scale demonstration. This paper will provide an update on the status of these projects covering ultra-low-NOx burners, advanced reburning, selective non-catalytic reduction (SNCR), selective catalytic reduction (SCR), methane de-NOx, and enhanced-oxygen combustion.

The activity of these catalysts for the reduction of NO by methane or propane has been investigated in simulated flue gas. The effects of sulphates on the catalyst, and of water vapour and/or gaseous sulphur dioxide have been examined for both the SCR of NOx by propane and direct decomposition of NO. Both copper sulphate on alumina and cerium sulphate on alumina are substantially less active for propane SCR than the respective oxides. Both catalyst types are reversibly inhibited by the presence of water vapour. The effect of sulphur dioxide in the gas stream appears to be only mildly inhibiting, but since the optimum temperature range for propane reduction of NO is the same as the optimum temperature range for SO2 absorption, the CuO/Al2O3 sorbent/catalyst will quickly become sulphated, even at low .ue gas SO2 concentrations. Methane was also examined as a reductant, and neither copper oxide/alumina nor cerium oxide/alumina is active for selective catalytic reduction of NOx with methane up to 775 K.

Net peak winter demand is expected to increase by over 1,600 megawatts (MW) or 3.3 percent per year and net summer peak demand is projected to increase by 1,250 MW or three percent per year. The Department of Energy (DOE) would provide financial assistance, through a cooperative Agreement with Kentucky Pioneer Energy, LLC (Kentucky Pioneer), a subsidiary of Global Energy, Inc., for the design, construction, and operation of a 540-MW demonstration power station comprised of two synthesis gas-fired combined cycle units. The project would demonstrate the capability of the integrated gasification combined cycle (IGCC) technology to allow the environmentally friendly use of high-sulfur bituminous coal and refuse-derived fuel in the generation of electrical power. The station would include a British Gas Lurgi gasifier to produce synthesis gas from a co-feed of coal and refuse-derived fuel pellets and a high-temperature molten carbonate fuel cell. The facility would be powered by the synthesis gas feed. The plant would consist of the following major components: refuse-derived fuel pellets and coal receipt and storage facilities; a gasification plant; sulfur removal and recovery facilities; an air separation plant; a high temperature molten carbonate fuel cell, and two combined cycle generators. At a minimum, 50 percent of the high sulfur coal used would be mined in the Kentucky region. In addition to the proposal, two No Action Alternatives are considered in this draft EIS. Under No Action Alternative 1, the DOE would not provide cost-shared funding for the project and no new facility would be constructed. Under No Action Alternative 2, DOE would not provide any funding, but Kentucky Pioneer would construct and operate a 540-MW natural-gas-fired power station. To support the project, EKPC would construct a 138-kilovolt electric transmission line extending 17 miles from the project site to the Spencer Terminal in Montgomery County, where it would interconnect with the existing local power grid. POSITIVE IMPACTS: In addition to demonstrating the feasibility of implementing IGCC on a broader basis, the facility would provide additional generating capacity to central and eastern Kentucky, a region that is suffering from a deficiency in this resource. The project would employ an average of 600 workers and result in the indirect creation of 690 to 1,150 jobs. The 20-year demonstration and operation period would employ 120 workers. NEGATIVE IMPACTS: The proposed action would disturb a maximum of 19 to 27 acres, including prime farmland soils and the associated wildlife habitat. Annual emissions from the plant would include 1,100 tons of nitrogen oxides, 800 tons of carbon monoxide 500 tons of sulfur oxides and 9.07 tons of hazardous air pollutants. The generators would consume four million gallons per day of surface water and generate 400,000 gallons per day of wastewater to be discharged into the Kentucky River after treatment.

Gel probes inserted into the sediments allowed analysis of the distribution and activity of bacterial sulfate reduction (BSR). A mixed population of sulfate-reducing bacteria enriched from anoxic wetland sediments was immobilized in low temperature-gelling agarose held in grooved rods or probes. The probes were inserted vertically into sediments and were allowed to incubate in situ for 48 h. After their retrieval, the gels were sectioned and analyzed for residual BSR activity and were compared to in situ BSR rates and chemical porewater profiles. The depth distribution of residual BSR activity in the immobilized cell gel probes differed significantly from the BSR measured in situ. Approximately 51% of the total integrated residual sulfate reduction activity measured in the gel probes occurred between 0 and 7 cm of the upper 20 cm of sediment. In contrast, ca. 99% of the integrated in situ BSR occurred between 7- and 20-cm depth, and only 1% of the total integrated rate occurred between 0- and 7-cm depth. Lactate-enriched bacteria immobilized in the gel may have been atypical of the majority of sulfate-reducing bacteria in the sediment. Agarose-immobilized sulfate-reducing bacteria might also be able to proliferate in the otherwise inhospitable zone of iron reduction, where sulfate and labile carbon compounds for which they are usually outcompeted can diffuse freely into the gel matrix. Gel probes containing particulate iron monosulfide (FeS) indicated that FeS remained stable in sediments at depths greater than 2 to 3 cm below the sediment-water interface, consistent with the shallow penetration of oxygen into surface sediments.

This produces extensive data files including values for 32 parameters that are difficult to evaluate for overall changes in water quality. Tracking a few major parameters, such as pH, Fe, or acidity, produces a complex data set that excludes other significant values. A quantitative measure of estimating if the overall change in water quality is an improvement, no significant change or deterioration should take into account all measured quantities. Since the variation in water quality parameters over time for this data set is not normally distributed, mean and standard deviation are not appropriate statistics. To assess the change in water quality at a site, a scatterscore evaluation was developed. In this reconnaissance method, a score is calculated based on the differences between up gradient (control) versus down gradient (treatment) water quality data sets. All parameters measured over a period of time at two sampling points are compared. The relationships between the range of measured values and the ratio of the medians for each parameter produces a data point that falls into one of four quadrants. Counting the number of values in each quadrant, multiplying by an appropriate weight and normalizing the final value produces a scatterscore that indicates the overall changes in water quality at mine sites where CCB were placed. This evaluation method, indicated that there was slight to moderate improvement in water quality at 30% of the CCB remediated sites and slight deterioration at 25% of the sites. The scatterscore at the remaining sites indicated random change in the measured parameters.

Recent developments indicate that the prospects for economic production of methane from hydrates are good, and could occur much sooner than previously thought. To ensure that the United States remains a leader in hydrates research and technology, the Department of Energy's (DOE) Strategic Center for Natural Gas (SCNG) at the National Energy Technology Laboratory (NETL) is charged with coordinating a comprehensive national research and development program in all aspects of methane hydrates. In advance of attempts at commercial exploitation, our program will support fundamental studies that will improve the understanding of the nature of hydrates, the impact of hydrates on the strength and stability of ocean-bottom sediments, and the interaction of the global hydrate reservoir with the world's oceans and atmosphere. This report outlines these key methane hydrate research and development (R&D) issues, reviews DOE's past and current hydrate programs, and outlines our plans for a coordinated and collaborative R&D program in which the nation's best minds are efficiently brought to bear on the challenge of maximizing the potential benefits of natural methane hydrates.

Fueled by the WWII war efforts, the aims of the project were to investigate the roles of physical, chemical and biological forces in the transformation of organic material into petroleum. Basic studies on microbial activities related to petroleum recovery and degradation were directed by marine microbiologist Dr. Claude ZoBell at Scripps Institution of Oceanography and the results were published extensively in journals and oil industry publications between 1943 and 1955. Studies by ZoBell's group established the presence of bacteria in recent and ancient sediments, in oil field fluids recovered from great depths, and living at extremely high temperatures and pressures. Specific bacteria were found to be instrumental in liberating oil from oil-bearing sedimentary rocks by dissolving carbonates, producing detergents, and decreasing the viscosity of oil. In addition, the ability of bacteria to degrade hydrocarbons was shown to be relatively commonplace, a characteristic that has been widely exploited in the bioremediation of accidental oil spills.

Influent and effluent water quality data have been analyzed to determine the long-term performance of each ALD for treating coal mine drainage. Alkalinity concentrations in the effluent of the ten ALDs ranged from 80-320 mg/L as CaCO sub(3) with near maximum levels of alkalinity being reached after approximately 15 hours of detention. ALDs that received mine water containing less than 1 mg/L of both ferric iron and aluminum have continued to produce consistent concentrations of alkalinity since their construction. However, an ALD that received 21 mg/L of aluminum experienced a rapid reduction in permeability and failed within eight months.

The partnerships consist of 216 organizations in 40 States, 4 Canadian Provinces, and 3 Indian Nations. Six of the Seven Phase I Partnerships are assessing the potential of terrestrial sequestration to mitigate carbon dioxide emissions emitted in their regions. Since the programs inception, the partnerships have been working on several activities designed to create the knowledge base and infrastructure for the selection of, and potential small-scale field validation tests during Phase II. During the first year of the program, the partnerships primary activities have focused on data collection and analysis. Partnerships are researching emissions data on point, industrial, and agricultural sources of C0 sub(2) and other greenhouse gases; potential geologic and terrestrial sinks; and existing and necessary transportation infrastructure in their regions. The data is being stored in regional databases and geographic information systems (GIS). Analysis of this data is being conducted with decision support tools that will be used to identify the most promising opportunities for sequestration in each region. They are identifying modeling and measurement technologies to for future accounting and monitoring networks for sequestration projects. Partnerships have also been conducting public outreach and education activities. DOE recognizes that terrestrial sequestration will play an important role in each regions portfolio to mitigate CO sub(2) emissions. The DOE's intent has been to leverage terrestrial sequestration R&D funded by other federal agencies to implement small-scale field demonstration projects. After assessing the regions sinks and implementing several validation projects, the partnerships will have rigorous project implementation protocols that could satisfy future carbon markets and the DOE EIA 1605B voluntary guidelines. For terrestrial sequestration activities, the first year has been dedicated to collecting data and developing regional GIS that will determine the regions potential to sequester carbon in various sinks as well as identify promising opportunities for small-scale validation tests. The partnerships geographic area includes 96% of the total land mass and 98.5% of the agricultural land in the United States. The regional partnership are collecting data from national data bases such as the 1978 National Resources Inventory (NRI); Major Land Resource Areas (MLRA); State Soil Geographic (STATSGO) Data Base for the Conterminous United States; 1992 Land Use Land Cover data (LULC); MODIS Net Primary Production data; and regional meteorological data from the National Climatic Data Center. The partnerships are also working with state and county offices to add to and refine these data sets to assess the sequestration potential for forests, agricultural lands, wetlands, and grazing lands. The solicitation for Phase II of the Regional Carbon Sequestration Partnerships initiative was released on December 14, 2004. The solicitation will provide up to $100 million over 4 years in federal funds for partnerships of state agencies, universities, private companies, and national laboratories that will field test and validate promising carbon sequestration technologies, both geologic and terrestrial.
