Numerical Simulation and Parameter Sensitivity Analysis of CO2 Flooding in Shale Gas Reservoir Yong Tang, Yulin Chen, Youwei He, Jiazheng Qin

Abstract

CO2 flooding presents a promising methodology for enhancing shale gas recovery. To research its feasibility and evaluate the ability of CO2 storage in the shale formations, we established a numerical simulation model of CO2 flooding in shale gas reservoirs based on the embedded discrete fracture model (EDFM). The study analyzed the effects of reservoir properties, well spacing, injection pressure, and injection rate on the CO2 flooding effectiveness in shale gas reservoirs. The CO2 flooding model established in this study employs geological parameters derived from actual shale gas reservoir data, ensuring high levels of authenticity. The research results can provide a reference for oilfields to implement CO2 flooding for enhanced shale gas recovery.
