Available in PDF, EPUB and Kindle. Book excerpt: This book offers readers a comprehensive overview, and an in-depth understanding, of suitable methods for quantifying and characterizing saline aquifers for the geological storage of CO2. It begins with a general overview of the methodology and the processes that take place when CO2 is injected and stored in deep saline-water-containing formations. It subsequently presents mathematical and numerical models used for predicting the consequences of CO2 injection. This book provides descriptions of relevant experimental methods, from laboratory experiments to field scale site characterization and techniques for monitoring spreading of the injected CO2 within the formation. Experiences from a number of important field injection projects are reviewed, as are those from CO2 natural analog sites. Lastly, the book presents relevant risk management methods. Geological storage of CO2 is widely considered to be a key technology capable of substantially reducing the amount of CO2 released into the atmosphere, thereby reducing the negative impacts of such releases on the global climate. Around the world, projects are already in full swing, while others are now being initiated and executed to demonstrate the technology. Deep saline formations are the geological formations considered to hold the highest storage potential, due to their abundance worldwide. To date, however, these formations have been relatively poorly characterized, due to their low economic value. Accordingly, the processes involved in injecting and storing CO2 in such formations still need to be better quantified and methods for characterizing, modeling and monitoring this type of CO2 storage in such formations must be rapidly developed and refined.

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: Anthropogenic levels of atmospheric greenhouse gases, particularly carbon dioxide (CO2) have increased rapidly over the last several decades and coincide with rising temperatures globally. One possible solution is to capture CO2 before it is released into the atmosphere by large point sources, such as fossil fuel power plants. Once captured, the CO2 can be condensed and transported to a storage facility. Of the available options for storage of condensed CO2, geologic sequestration in deep saline aquifers is considered the most viable option. Porosity measurements were obtained for nearly 100 core samples of the Knox and Stones River groups from the middle Tennessee area as part of a larger project for the Tennessee Division of Geology, characterizing the potential for geologic CO2 sequestration in Tennessee. Certain formations within these groups were found to exhibit higher porosity (higher storage potential) than others. Measured porosity values were quite low, ranging from 0.21 - 10.67 % with a median value of 1.21 %. These data can be used to aid in the decision making process concerning possible geologic targets for geologic CO2 sequestration in Tennessee. A sensitivity analysis was also performed using a numerical model for geologic carbon sequestration (STOMP). Intrinsic permeability, porosity, pore compressibility, the van Genuchten residual liquid saturation, [alpha] and m parameters, and the Brooks and Corey residual liquid and gas saturations were varied independently and their influence on CO2 storage was determined. Changes in costs based on the parameter variations were calculated to evaluate the relative importance of the various parameters. The most influential parameters were intrinsic permeability, the van Genuchten m parameter, and the Brooks and Corey residual gas saturation. These results highlight the need for accurate measurement of intrinsic permeability and capillary pressure saturation parameters in addition to more commonly measured properties like porosity.

Book excerpt: CO2 sequestration is one of the proposed methods for reducing anthropogenic CO2 emissions to the atmosphere and therefore mitigating global climate change. Few studies on storing CO2 in an aquifer have been conducted on a regional scale. This study offers a conceptual approach to increasing the storage efficiency of CO2 injection in saline formations and investigates what an actual CO2 storage project might entail using field data for the Woodbine aquifer in East Texas. The study considers three aquifer management strategies for injecting CO2 emissions from nearby coal-fired power plants into the Woodbine aquifer. The aquifer management strategies studied are bulk CO2 injection, and two CO2-brine displacement strategies. A conceptual model performed with homogeneous and average reservoir properties reveals that bulk injection of CO2 pressurizes the aquifer, has a storage efficiency of 0.46% and can only last for 20 years without risk of fracturing the CO2 injection wells. The CO2-brine displacement strategy can continue injecting CO2 for as many as 240 years until CO2 begins to break through in the production wells. This offers 12 times greater CO2 storage efficiency than the bulk injection strategy. A full field simulation with a geological model based on existing aquifer data validates the storage capacity claims made by the conceptual model. A key feature in the geological model is the Mexia-Talco fault system that serves as a likely boundary between the saline aquifer region suitable for CO2 storage and an updip fresh water region. Simulation results show that CO2 does not leak into the fresh water region of the iv aquifer after 1000 years of monitoring if the faults have zero transmissibility, but a negligible volume of brine eventually gets through the mostly sealing fault system as pressure across the faults slowly equilibrates during the monitoring period. However, for fault transmissibilities of 0.1 and 1, both brine and CO2 leak into the fresh water aquifer in increasing amounts for both bulk injection and CO2-brine displacement strategies. In addition, brine production wells draw some fresh water into the saline aquifer if the Mexia-Talco fault system is not sealing. A CO2 storage project in the Woodbine aquifer would impact as many as 15 counties with high-pressure CO2 pipelines stretching as long as 875 km from the CO2 source to the injection site. The required percentage of power plant energy capacity was 7.43% for bulk injection, 7.9% for the external brine disposal case, and 10.2% for the internal saturated brine injection case. The estimated total cost was $0.001320́3$0.00146/kWh for the bulk injection, $0.001910́3$0.00211/kWh for the external brine disposal case, and $0.00190́3$0.00209/kWh for the internal saturated brine injection case.

This book was released on 2017 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: To be relevant for greenhouse gas mitigation, geological CO2 storage in a deep saline aquifer must be scalable, and the stored CO2 must be securely contained. Conventional approaches to aquifer storage have both scalability and containment risks. In this work, the scalability risks of interest are the achievable sustained injection rates of CO2 and storage efficiencies. The containment risks examined here are associated with uncontrolled fracture initiation and propagation in the injection zone, and CO2 leakage. Operational strategies for minimizing the risks of scalability and containment while maximizing the injection rate and storage efficiency are important to support commercially viable implementations of numerous large-scale CO2 storage projects. We focus on the CO2 storage by surface dissolution strategy, which stores the captured CO2 in a storage aquifer by dissolving it into brine extracted from the storage formation and then injecting CO2-saturated brine into the same storage formation. This method has advantages over the standard CO2 storage method in eliminating or reducing certain containment risks, but it still faces the scalability risks of achieving large injection rates. We quantify the maximum injection rate of CO2-saturated brine for a safe storage project, by preventing the initiation and propagation of tensile fractures. We incorporate thermal constraints in our model by including the induced thermoelastic stress in the calculation of the formation breakdown pressure. We design a closed-loop surface dissolution technique that completely eliminates the problem of brine disposal. However, when using this technique the buildup of reservoir pressure gradually reduces the maximum injection rate. We propose a strategy to manage the pressure distribution and maximize the injection rates for each injector. Yet in large-scale geological CO2 storage projects, injection-induced fracturing may be unavoidable when injecting at desired rates. We develop models to analyze injection data from a field supercritical CO2 injection project. The analysis suggests that proper pressure management could stop the propagation of injection-induced fractures. This self-limiting feature of injection-induced fracturing mitigates the containment risks and greatly increases the injection rates. To improve the aquifer utilization efficiency for CO2 storage using the surface dissolution strategy, we continue injecting CO2-saturated brine beyond the pressure contour corresponding to the bubble point. However, this introduces the risks of CO2 leakage. We develop a 1D model in a homogeneous aquifer to study the migration of two-phase fluid flow. Two limiting cases are studied to confine the mobility of free gaseous phase. The results indicate a significant increase in stored CO2 with low risks of leakage because of the small saturation and mobility of exsolved CO2. Allowing the breakthrough of injected CO2-saturated brine at the producers would also increase the aquifer utilization efficiency. The aquifer utilization efficiency can be optimized by minimizing the production/recycling rate of CO2-saturated brine in heterogeneous fields. The results show greatly improved aquifer utilization efficiencies at the cost of handling a small pore volume of produced/recycled CO2-saturated brine.

Book excerpt: Storage of carbon dioxide is being actively considered for the reduction of green house gases. To make an impact on the environment CO2 should be put away on the scale of gigatonnes per annum. The storage capacity of deep saline aquifers is estimated to be as high as 1,000 gigatonnes of CO2.(IPCC). Published reports on the potential for sequestration fail to address the necessity of storing CO2 in a closed system. This work addresses issues related to sequestration of CO2 in closed aquifers and the risk associated with aquifer pressurization. Through analytical modeling we show that the required volume for storage and the number of injection wells required are more than what has been envisioned, which renders geologic sequestration of CO2 a profoundly nonfeasible option for the management of CO2 emissions unless brine is produced to create voidage and pressure relief. The results from our analytical model match well with a numerical reservoir simulator including the multiphase physics of CO2 sequestration. Rising aquifer pressurization threatens the seal integrity and poses a risk of CO2 leakage. Hence, monitoring the long-term integrity of CO2 storage reservoirs will be a critical aspect for making geologic sequestration a safe, effective and acceptable method for greenhouse gas control. Verification of long-term CO2 residence in receptor formations and quantification of possible CO2 leaks are required for developing a risk assessment framework. Important aspects of pressure falloff tests for CO2 storage reservoirs are discussed with a focus on reservoir pressure monitoring and leakage detection. The importance of taking regular pressure falloffs for a commercial sequestration project and how this can help in diagnosing an aquifer leak will be discussed. The primary driver for leakage in bulk phase injection is the buoyancy of CO2 under typical deep reservoir conditions. Free-phase CO2 below the top seal is prone to leak if a breach happens in the top seal. Consequently, another objective of this research is to propose a way to engineer the CO2 injection system in order to accelerate CO2 dissolution and trapping. The engineered system eliminates the buoyancy-driven accumulation of free gas and avoids aquifer pressurization by producing brine out of the system. Simulations for 30 years of CO2 injection followed by 1,000 years of natural gradient show how CO2 can be securely and safely stored in a relatively smaller closed aquifer volume and with a greater storage potential. The engineered system increases CO2 dissolution and capillary trapping over what occurs under the bulk phase injection of CO2. This thesis revolves around identification, monitoring and mitigation of the risks associated with geological CO2 sequestration.
