Numerical study of underground CO2 storage and the utilization in depleted gas reservoirs by Cheng Cao Pdf

Carbon capture and storage (CCS) is considered as the most promising technology for slowing down the atmospheric CO2 emissions. However, CCS has not been implemented on large scale because of the related risks and the lack of financial incentives. Regarding the risks associated with CCS, a parametric uncertainty analysis for CO2 storage was conducted and the general roles of different key geomechanical and hydrogeological parameters in response to CO2 injection were determined, which is beneficial for guiding time and effort spent mitigating the uncertainty to acquire trustworthy model forecasts and risk assessments. Regarding the financial incentives of CCS, co-injection of CO2 with impurities associated with enhanced gas recovery was analyzed, which is advantageous for decreasing the cost on gas separation and generating additional economic profit. In addition, the utilization of CO2 as cushion gas in the underground gas storage reservoir was proposed and analyzed, which can also be beneficial for improving the cost-effectiveness of CCS. Overall, this thesis is advantageous for promoting the application of CCS on large scale and mitigating the atmospheric CO2 emissions. Die Kohlenstoffabscheidung und –speicherung (CCS) gilt als die vielversprechendste Technologie zur Verlangsamung der atmosphärischen CO2–Emissionen. CCS wurde jedoch aufgrund der damit verbundenen Risiken und des Mangels an finanziellen Anreizen nicht in großem Umfang implementiert. In Bezug auf die mit CCS verbundenen Risiken wurde eine parametrische Unsicherheitsanalyse für die CO2-Speicherung durchgeführt und die allgemeinen Rollen verschiedener geomechanischer und hydrogeologischer Schlüsselparameter als Reaktion auf die CO2-Injektion ermittelt. Dies ist hilfreich, um den Zeit- und Arbeitsaufwand für die Minderung der Unsicherheit zu verringern, um vertrauenswürdig zu werden Modellprognosen und Risikobewertungen. In Bezug auf die finanziellen Anreize von CCS wurde die gleichzeitige Injektion von CO2 mit Verunreinigungen im Zusammenhang mit einer verbesserten Gasrückgewinnung analysiert. Dies ist vorteilhaft, um die Kosten für die Gastrennung zu senken und zusätzlichen wirtschaftlichen Gewinn zu erzielen. Darüber hinaus wurde die Verwendung von CO2 als Polstergas im unterirdischen Gasspeicher vorgeschlagen und analysiert, was auch zur Verbesserung der Wirtschaftlichkeit von CCS beitragen kann. Insgesamt ist diese These vorteilhaft, um die Anwendung von CCS in großem Maßstab zu fördern und die atmosphärischen CO2-Emissionen zu verringern.

Numerical study of physico- chemical interactions for CO2 sequestration and geothermal energy utilization in the Ordos Basin, China by Hejuan Liu Pdf

In this dissertation, three simulators (i.e. TOUGH2MP, TOUGHREACT and FLAC3D) were used to simulate the complex physical and chemical interactions induced by CO2 sequestration. The simulations were done instages, ranging from the two phase (water and CO2) fluid flow (H2), through coupled hydro-mechanical effects (H2M) and geochemical responses (i.e. CO2-water-rock interactions (H2C)), to the extension of CCS to CCUS by the application of combined geothermal production and CO2 sequestration technologies. The findings of this study are essential for a thorough understanding of the complex interactions in the multiphase, multicomponent porous media controlled by different physical and chemical mechanisms. Furthermore, the simulation results will provide an invaluable reference for field operations in CCS projects, especially for the full-integration pilot scale CCS project launched in the Ordos Basin. Subsequently, a preliminary site selection scheme for the combined geothermal production and CO2 sequestration was set up, which considered various factorsinvolved in site selection, ranging from safety, economical, environmental and technical issues. This work provides an important framework for the combined geothermal production and CO2 sequestration project. However, further numerical and field studies are still needed to improve on a series of criteria and related parameters necessary for a better understanding of the technology.

Numerical study of coupled THM/C processes related to geo-energy production by Yang Gou Pdf

In this thesis a parallel simulation platform, namely TOUGH2MP-FLAC3Dplus, was further developed by linking the multiphase multicomponent flow code TOUGH2MP and the further developed geomechanical code FLAC3Dplus for large-scale simulation of the coupled THM/C processes related to geo-energy production. A series of mathematical/physical models were developed and implemented in this platform, including (1) an improved equation of state for CO2-CH4-H2O-NaCl system which considers the effect of salt on phase partition and fluid properties in gas reservoirs; (2) a modified coupling approach for the simulation of hydraulic fracturing in tight geo-reservoirs, which considers the multiphase multicomponent leakoff effects; (3) a thermo-hydro-mechanical model based on a crack tensor for naturally fractured rock masses and faults. All these verified models have been applied in three different case studies, including CO2 enhanced gas recovery (EGR) in the Altmark natural gas field; (2) Hydraulic fracturing in three different types of geo-reservoirs (tight gas, oil and geothermal reservoir); (3) Geothermal energy utilization induced seismicity in Unterhaching. The developed models and the numerical platform can be used to predict the coupled THM/C behavior of rock formations, to optimize the CO2-EGR and hydraulic fracturing in tight geo-reservoirs, as well as reduce the geo-risks related to geo-energy production.

Geologic Carbon Sequestration by V. Vishal,T.N. Singh Pdf

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.

Numerical and Analytical Modeling of Gas Mixing and Bio-Reactive Transport during Underground Hydrogen Storage by Birger Hagemann Pdf

In this thesis the major differences between underground hydrogen storage and the conventional storage of natural gas are lined out to be bio-reactive and gas mixing phenomena. A new mathematical model was developed to describe the coupling between two-phase flow and microbial populations which consume hydrogen for their metabolism. Different analytical and numerical techniques were applied to investigate the storage of hydrogen in the geological subsurface. An analytical solution was derived for gravity-driven multi-component two-phase flow in heterogeneous porous media. Oscillating scenarios, similar to Turing instability, were detected. Storage scenarios were simulated including a field scale demonstration in a realistic geological model.

CO2 Storage in Carboniferous Formations and Abandoned Coal Mines by Manchao He,Luis Ribeiro e Sousa,Derek Elsworth,Euripedes Vargas Jr. Pdf

Underground geological storage of carbon dioxide (CO2) has considerable potential for mitigating climate change. CO2 can be safely injected and stored at well characterized and properly managed sites. Injecting carbon dioxide in deep geological formations can store it underground for long periods of time. Depleted oil and gas reservoirs, saline aquifers and carboniferous formations can be used for storage of CO2, as well as in abandoned coal mines. At depths below about 800-1000m, CO2 has a liquid-like density that permits the efficient use of underground reservoirs in porous sedimentary rocks. The papers in the present volume are from leading experts in the field of CO2 storage and were presented at an International Workshop on CO2 Storage in Carboniferous Formations and Abandoned Coal Mines (Beijing, China, 8-9 January 2011). CO2 storage in abandoned coal mines appears to have a bright future. Although CO2 Storage in Carboniferous Formations and Abandoned Coal Mines is primarily intended for mining engineers, environmental engineers and engineering geologists, the book will also be useful to civil engineers, and academics and professionals in geophysics and geochemistry.
