The CO2 Capture Project Phase 2 (CCP2) Storage Program: Progress in Geological Assurance in Unmineable Coal Beds

The CO2 Capture Project’s (CCP) Phase 2 program made significant progress addressing issues to facilitate assurance of the safety and security of geological storage of CO2. This work included stakeholder assurance of CO2 storage in unmineable coal beds. Simulation studies of CO2 injection into coal beds were designed to identify operating conditions that will minimize leakage of CO2 and maximize production of methane. Geophysical models were used to simulate gravity and electromagnetic responses from coal beds containing CO2. Hyperspectral remote sensing was evaluated for its ability to detect leakage of CO2 and CH4 to the surface.
