Numerical study of underground CO2 storage and the utilization in depleted gas reservoirs

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 v
