Summary:
Recently, studies on greenhouse gases capture and storage have been actively carried out and CO2 storage project is going on in South Korea. The purpose of this study is to analyze the pressure changes caused by CO2 injection in order to prevent the fault reactivation caused by excessive injection during the storage of CO2 in a saline aquifer and to analyze the co2 migration distance. To ensure the safety, it is essential to analyze the CO2 leakage through the fault. Therefore, the possibility of leakage was assessed based on the maximum allowable pressure of cap rock and the fault reopening pressure. With the analysis of the pressure increase and CO2 migration distance, the proper daily injection rate and maximum storage volume to minimize the possibility of leakage.
