Numerical study on thermal performance of enhanced geothermal system with CO2 using multistage hydraulic stimulation

Abstract A novel collaborative research project aimed at utilizing CO2 to create an artificial geothermal reservoir and extract heat by circulating CO2 was initiated in 2021. In this study, we demonstrated that CO2 may significantly enhance thermal power production in geothermal reservoirs over the...
