Research progress and prospects of CO2 enhanced shale gas recovery and geologic sequestration
CO2 injection to strengthen shale gas development is a new technology to improve shale gas recovery and realize geologic sequestration. Many scholars have studied these aspects of this technology: mechanism of CO2 displacement CH4, CO2 and CH4 adsorption capacity, affecting factors of shale adsorpti...

CO2 injection to strengthen shale gas development is a new technology to improve shale gas recovery and realize geologic sequestration.
