Economic Feasibility Evaluation of CO2-ECBM: A Case Study in Qinshui Basin, China
Abstract:
For carbon dioxide capture and geologic storage to be deployed commercially and in a widespread manner will require well thought out economic feasibility. As one of the main coalbed methane resource reservoirs of China, Qinshui Basin is being widely technical studied about how to enhance coalbed methane recovery by CO2 injection (CO2-ECBM). In this study, an economic feasibility evaluation is presented to discuss economy to the CO2-ECBM, and how to choose the best exploit scheme. Two exploiting schemes were compared. The evaluation results show the exploit scheme that the CO2 storage potential is designed 1.5 Mt/year, the well configuration pattern is 5-spot 160 ac, and the exploited area is 194 km2 is a better choice. The sensitivity analysis results show the profit is the most sensitive parameter, which reminds us should strictly control this uncertainty. The CO2-ECBM project has a strong robustness, and the Qinshui Basin has a further CO2-ECBM prospect from economical view.
