Book excerpt: The concept of displacement of sorbed methane and enhancement of coalbed methane recovery by injecting CO2 into coal reservoirs, while simultaneously sequestering the CO2 , has been studied over the last few years. Preferential adsorption of CO2 over methane is considered to be responsible for the ability of the former to displace the adsorbed methane. The primary objective of this study was to investigate the ability of CO2 to displace and enhance the recovery of sorbed methane, when injected in coals after partial production. A secondary objective was to study the sorption of methane and CO2 on coals to investigate the degree to which coal exhibits preferential sorption for one over the other. During the first experimental phase, single component adsorption experiments were carried out using pure methane and CO2 on coals from the San Juan and Illinois Basins, and the relative (CO2 :CH4 ) sorption values were calculated. As a part of this study, applicability of different adsorption models, such as Langmuir, Dubinin-Polanyi (D-P), and BET equations were tested for adsorption of methane and CO2 on coals. In the second phase, CO2 injection experiments were carried out after partial desorption of methane to study its effect on desorption of additional methane. Finally, numerical simulation was undertaken to estimate the incremental methane recovery by injection of CO2 as compared to production by the primary recovery method. The results showed that CO2 adsorbed preferentially (approximately 3 times more) over methane. CO2 injection experiments showed that, in most cases, injected CO2 displaced all of the sorbed methane, while the total pressure was maintained at high levels. However, this effect was not universal. In some cases, injection of CO2 was effective only until a certain point, after which it did not result in recovery of additional methane. In other cases, the injected CO2 led to re-adsorption of methane, thus delaying the methane recovery. The results also suggested that competitive sorption, as in the case of CO2 injection in coals, is very complex and the mechanism may be significantly different from that in pure gas adsorption. The D-A equation best fit the adsorption data for both methane and CO2 for the pressure range tested. The Langmuir equation also gave a good fit, while the BET equation did not fit well. The simulation study showed that it is possible to obtain significant improvement in methane recovery by injection of CO2.

Book excerpt: This exclusive compilation written by eminent experts from more than ten countries, outlines the processes and methods for geologic sequestration in different sinks. It discusses and highlights the details of individual storage types, including recent advances in the science and technology of carbon storage. The topic is of immense interest to geoscientists, reservoir engineers, environmentalists and researchers from the scientific and industrial communities working on the methodologies for carbon dioxide storage. Increasing concentrations of anthropogenic carbon dioxide in the atmosphere are often held responsible for the rising temperature of the globe. Geologic sequestration prevents atmospheric release of the waste greenhouse gases by storing them underground for geologically significant periods of time. The book addresses the need for an understanding of carbon reservoir characteristics and behavior. Other book volumes on carbon capture, utilization and storage (CCUS) attempt to cover the entire process of CCUS, but the topic of geologic sequestration is not discussed in detail. This book focuses on the recent trends and up-to-date information on different storage rock types, ranging from deep saline aquifers to coal to basaltic formations.

Available in PDF, EPUB and Kindle. Book excerpt: The term 'geological sequestration' stands for the capture of CO2 directly from anthropogenic sources and disposing of it deep into the ground for geologically significant periods of time (Bachu, 2002). Coal seam sequestration as described by White et al. (2005) is "the storage of CO2 from anthropogenic sources into deep, unminable coal seams for geologically significant limits with or without concomitant recovery of natural gas".Methane is native to coal and has its origin in coalification process. Coal is the source as well as reservoir to significant quantities of methane, a potential energy resource. Coalbed methane (CBM) a bonus non-conventional energy source is generated mainly due to geochemical transformation of the organic matter by catagenesis. CO2 injection reduces the partial pressure of methane and enhances desorption of methane from the matrix. CO2 has an additional effect compared to other gases that it is preferentially adsorbed onto coal surfaces, displacing methane from adsorption sites. CO2-ECBM sequestration is a value addition project in management of increasing atmospheric concentration of greenhouse gases (GHG) as it recovers the cost of capture, processing, transportation and storage of CO2 by production of methane.The primary aim of this research was to develop an understanding on the coal-fluid interaction pertinent to carbon storage in coal seams with special reference to Indian coal basins. Damodar valley coalfield where production of coalbed methane is being carried out was chosen for this study. The objectives of this study included detailed knowledge of geotechnical characterization of coal measure rocks, strength characteristics of coal under saturation in different media, swelling and stress induced changes in flow behaviour of coal in multiple phases of carbon dioxide and estimation of gas storage potential of Indian coal basins.After the geological field work, petrographic and geomechanical characterization of coal measure rocks was carried out. Sandstone and shale along with varying degrees of their intercalations were identified in thin section studies under the microscope. The pertinent geomechanical characteristics of the rocks and coal were determined using laboratory tests according to the International Society of Rock Mechanics (ISRM) standards. Some data generated during these tests were used as inputs for prediction of Uniaxial Compressive Strength (UCS) and P-wave velocity using soft computing. An important aspect of coal seam sequestration is the influence of CO2 saturation on strength parameters and failure characteristics of the host. Fluid saturation experiments were carried out to explore the effects of CO2 adsorption on natural as well as moisture-equilibrated coal. Water saturation of coal led to high reduction in its strength implying that the seam pressure in water saturated sinks must be managed at lower levels during sequestration as compared to the dry reservoirs. Injection of CO2 leads to sorptive weakening of coal. The scenario was worst when CO2 was injected in wet coal. CO2 saturation induces swelling in coal and creates or enhances the fracture lines along coal as also evident by the early crack initiation in the acoustic emission results. Coupled stress strain data during uniaxial compression were recorded and analyzed. Introduction of water and CO2 caused early failure of coal samples at a lower value of load alongside inducing larger amount of strain at same stress values. The brittle nature of coal became less pronounced upon water saturation leading to larger time for crack initiation. To overcome the structural heterogeneity in coal, reconstituted coal specimens of uniform grain size were prepared using moulds and their strength was calculated under dry and saturated conditions. The reconstituted coal specimens were developed at different stresses and the properties of coal developed at 22 MPa and 24 MPa were found to be closest to that of natural coal. The magnitude of strength reduction in these samples was less as compared to the natural specimens. This could be due to high compaction and elimination of flow paths for fluids. Sample interiors remained largely intact and least affected by the fluids and hence, the strength remained closer to unsaturated reconstituted coal specimens.Permeability in coal is one of the most vital issues that determine the production or sequestration performance of coal. The permeability of CO2 in different phases in coal samples under various possible scenarios was estimated using a newly developed, high precision P-T controlled triaxial set up. The permeability of coal decreased exponentially with increasing effective stresses for Indian coal and new empirical equations accounting for stress behaviour of coal permeability were proposed. The rate of coal matrix swelling reduced in 30-40 hours of gas injection after which coal permeability gradually increased with increasing upstream pressure. Finally, at constant pore pressure, coal permeability reduced drastically with increasing confining stresses. A similar experiment was conducted using naturally fractured coal from the same seam while maintaining a low range of confining and injection pressures to ensure a complete gas phase CO2 flow. The permeability of coal reduced with increasing CO2 injection pressure in four out of five cases of confinement implying that complete closure of fractures due to coal swelling took longer time of CO2 saturation. However, permeability of coal reduced exponentially with increasing effective stresses. The next experiment investigated liquid and supercritical CO2 permeability of coal at varying confining pressures (15 - 24 MPa), corresponding to different depths of coal. The initial liquid CO2 permeability of coal at 10 MPa injection pressure reduced from 0.011 mD at 15 MPa confinement to 0.0004 mD at 24 MPa confinement. Further experiments revealed that the initial permeability of coal using supercritical CO2 (0.005 mD) was nearly half of that for liquid CO2 (0.011 mD). Nitrogen, used as a relatively inert medium, experienced a reduction in permeability in coal through which CO2 was passed. Maximum reduction in coal permeability was observed in supercritical CO2 flow, due to high sorption induced swelling of coal. After the role of confining stresses in different phase of CO2 was studied, the role of CO2 saturation period on coal permeability was studied at a fixed confining pressure of 18 MPa. Permeability of liquid as well as supercritical CO2 reduced after each period of 20 h saturation. Maximum permeability reduction took place by nearly 27% and 43% for liquid and supercritical CO2 saturation respectively, in the first out of three saturation periods. However, permeability of supercritical CO2 continued to reduce after each period of saturation while minimal reduction took place at the end of second and third period of swelling with liquid CO2. Similar trends were also observed in case of N2 since the cleats were effectively closed due to passage of different phases of CO2. This highlights that supercritical state of CO2 induces maximum adsorption related swelling and the subsequent reduction in coal permeability.Based on detailed experimental understanding of the coal samples and the field information on behaviour of coal seams, reservoir simulation studies were carried out using a commercial simulator called COMET 3. Model construction was followed by history matching of the CBM wells to establish and validate those before extending the cases for CO2 injection and enhanced recovery of the natural gas. The same established models were used to investigate parametric influence on production characteristics of coal. In a scenario of given block size with one injection well and two production wells, the spatial distribution and relative flow of the two gases were explored with change in time. The salient findings of these studies included: coals adsorbed CO2 quickly and surrounding matrix attained peak CO2 matrix concentration in one month due to high adsorption potential for CO2. The fracture gas saturation increased at first mainly near the production well due to sudden desorption of CH4 as a consequence of dewatering. Gradually, high gas saturation resulted in the block. The statistical data generated from this study revealed that over a period of 4000 days of observation, the coal block would take in approximately 7.7 bcf of CO2 and in lieu of which it would produce around 2.6 bcf of CH4 and a total of 12000 bbls of water. Similar exercise was carried out for two blocks in Jharia coalfields. The study on one block showed that over a period of 4000 days, the chosen coal block adsorbed approximately 7.75 bcf of CO2 in turn released 2.24 bcf of methane gas. The same variety of coal was simulated for a period of 20 years with an increased block size and it was found that for the chosen dimensions of Gondwana coal block in India, a total of 15.1 bcf of CO2 may be injected for permanent storage alongside recovery of not less than 5 bcf of methane. Numerical simulation for the established Jharia model was used to predict and understand the influence of sorption time on the production behaviour of coals. It revealed that the CO2 injection capacity into high sorption time coal was significantly higher than coal with low sorption time. Therefore, if not suitable for economical extraction of methane, these may alternatively be utilized as CO2 sinks. It was also shown that for coal belonging to Gondwana basin setting in India, sorption time less than 10 days followed equilibrium model of desorption. Although coals with higher sorption time exhibited non-equilibrium desorption and diffusion, they were finally observed to converge with the equilibrium model at later stages of gas injection/production. Some future works based on the new findings were suggested at the end of this research work.

Book excerpt: This book gives background information why shale formations in the world are important both for storage capacity and enhanced gas recovery (EGR). Part of this book investigates the sequestration capacity in geological formations and the mechanisms for the enhanced storage rate of CO2 in an underlying saline aquifer. The growing concern about global warming has increased interest in geological storage of carbon dioxide (CO2). The main mechanism of the enhancement, viz., the occurrence of gravity fingers, which are the vehicles of enhanced transport in saline aquifers, can be visualized using the Schlieren technique. In addition high pressure experiments confirmed that the storage rate is indeed enhanced in porous media. The book is appropriate for graduate students, researchers and advanced professionals in petroleum and chemical engineering. It provides the interested reader with in-depth insights into the possibilities and challenges of CO2 storage and the EGR prospect.

Book excerpt: BP Corporation North America, Inc. (BP) currently operates a nitrogen enhanced recovery project for coal bed methane at the Tiffany Field in the San Juan Basin, Colorado. The project is the largest and most significant of its kind wherein gas is injected into a coal seam to recover methane by competitive adsorption and stripping. The Idaho National Engineering and Environmental Laboratory (INEEL) and BP both recognize that this process also holds significant promise for the sequestration of carbon dioxide, a greenhouse gas, while economically enhancing the recovery of methane from coal. BP proposes to conduct a CO2 injection pilot at the tiffany Field to assess CO2 sequestration potential in coal. For its part the INEEL will analyze information from this pilot with the intent to define the Co2 sequestration capacity of coal and its ultimate role in ameliorating the adverse effects of global warming on the nation and the world.

Available in PDF, EPUB and Kindle. Book excerpt: Due to increasing atmospheric CO2 concentrations causing the global energy and environmental crises, geological sequestration of carbon dioxide is now being actively considered as an attractive option to mitigate greenhouse gas emissions. One of the important strategies is to use deep unminable coal seams, for those generally contain significant quantities of coal bed methane that can be recovered by CO2 injection through enhanced coal bed natural gas production, as a method to safely store CO2. It has been well known that the adsorbing CO2 molecules introduce structural deformation, such as distortion, shrinkage, or swelling, of the adsorbent of coal organic matrix. The accurate investigations of CO2 sorption capacity as well as of adsorption behavior need to be performed under the conditions that coals deform. The U.S. Department of Energy-National Energy Technology Laboratory and Regional University Alliance are conducting carbon dioxide sorption isotherm experiments by using manometric analysis method for estimation of CO2 sorption capacity of various coal samples and are constructing a gravimetric apparatus which has a visual window cell. The gravimetric apparatus improves the accuracy of carbon dioxide sorption capacity and provides feasibility for the observation of structural deformation of coal sample while carbon dioxide molecules interact with coal organic matrix. The CO2 sorption isotherm measurements have been conducted for moist and dried samples of the Central Appalachian Basin (Russell County, VA) coal seam, received from the SECARB partnership, at the temperature of 55 C.

This book was released on 2014 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Coal-Seq consortium is a government-industry collaborative that was initially launched in 2000 as a U.S. Department of Energy sponsored investigation into CO2 sequestration in deep, unmineable coal seams. The consortium's objective aimed to advancing industry's understanding of complex coalbed methane and gas shale reservoir behavior in the presence of multi-component gases via laboratory experiments, theoretical model development and field validation studies. Research from this collaborative effort was utilized to produce modules to enhance reservoir simulation and modeling capabilities to assess the technical and economic potential for CO2 storage and enhanced coalbed methane recovery in coal basins. Coal-Seq Phase 3 expands upon the learnings garnered from Phase 1 & 2, which has led to further investigation into refined model development related to multicomponent equations-of-state, sorption and diffusion behavior, geomechanical and permeability studies, technical and economic feasibility studies for major international coal basins the extension of the work to gas shale reservoirs, and continued global technology exchange. The first research objective assesses changes in coal and shale properties with exposure to CO2 under field replicated conditions. Results indicate that no significant weakening occurs when coal and shale were exposed to CO2, therefore, there was no need to account for mechanical weakening of coal due to the injection of CO2 for modeling. The second major research objective evaluates cleat, Cp, and matrix, Cm, swelling/shrinkage compressibility under field replicated conditions. The experimental studies found that both Cp and Cm vary due to changes in reservoir pressure during injection and depletion under field replicated conditions. Using laboratory data from this study, a compressibility model was developed to predict the pore-volume compressibility, Cp, and the matrix compressibility, Cm, of coal and shale, which was applied to modeling software to enhance model robustness. Research was also conducted to improve algorithms and generalized adsorption models to facilitate realistic simulation of CO2 sequestration in coal seams and shale gas reservoirs. The interaction among water and the adsorbed gases, carbon dioxide (CO2), methane (CH4), and nitrogen (N2) in coalbeds is examined using experimental in situ laboratory techniques to comprehensively model CBM production and CO2 sequestration in coals. An equation of state (EOS) module was developed which is capable of predicting the density of pure components and mixtures involving the wet CBM gases CH4, CO2, and N2 at typical reservoir condition, and is used to inform CO2 injection models. The final research objective examined the effects adsorbed CO2 has on coal strength and permeability. This research studied the weakening or failure of coal by the adsorption of CO2 from empirically derived gas production data to develop models for advanced modeling of permeability changes during CO2 sequestration. The results of this research effort have been used to construct a new and improved model for assessing changes in permeability of coal reservoirs due CO2 injection. The modules developed from these studies and knowledge learned are applied to field validation and basin assessment studies. These data were used to assess the flow and storage of CO2 in a shale reservoir, test newly developed code against large-scale projects, and conduct a basin-oriented review of coal storage potential in the San Juan Basin. The storage potential and flow of CO2 was modeled for shale sequestration of a proprietary Marcellus Shale horizontal gas production well using COMET3 simulation software. Simulation results from five model runs indicate that stored CO2 quantities are linked to the duration of primary production preceding injection. Matrix CO2 saturation is observed to increase in each shale zone after injection with an increase in primary production, and the size o ...

Book excerpt: To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Unminable coal beds have been recommended as good CO2 sequestration sites as the world prepares to sequester large amounts of greenhouse gases. In the U.S., these coal seams have the capacity to adsorb and sequester roughly 50 years of CO2 emissions from all the U.S. coal-fired power plants at today's output rates. The amount and type of gas ad-sorbed in coal has a strong impact on the permeability of the coal seam. An improved mixed gas adsorption iso-therm model based on the extended-Langmuir theory is discussed and is applied to mixed gas sorption-induced strain based on pure gas strain data and a parameter accounting for gas-gas interactions that is independent of the coal substrate. Advantages and disadvantages of using freestanding versus constrained samples for sorption-induced strain measurements are also discussed. A permeability equation used to model laboratory was found to be very accurate when sorption-induced strain was small, but less accurate with higher strain gases.
