Impact of CO2-water-coal on enhanced coalbed methane recovery by CO2 injection in Huainan coalfield

Impact of CO2-water-coal on enhanced coalbed methane recovery by CO2 injection in Huainan coalfield

CO2-enhanced coalbed methane recovery (CO2-ECBM) is a key method for CO2 geological utilization and sequestration. It holds promise for addressing challenges such as soft, low-permeability coal seams with difficult gas extraction, poor development performance, rapid production decline, and low recov...
