An experimental study of CH4 displacement by CO2 under varying initial reservoir pressures

An experimental study of CH4 displacement by CO2 under varying initial reservoir pressures

ObjectiveThis study aims to reveal the evolutionary patterns of reservoir parameters during the CO2-enhanced coalbed methane (CO2-ECBM) recovery and the impact of initial reservoir pressure on CBM recovery by gas injection. MethodsBased on the multi-field coupling-based physical simulation experimen...
