Geological CO2 storage and methane recovery in heterogeneous coal seams: Fractal descriptors for parameter upscaling
CO 2 -enhanced coalbed methane recovery (CO 2 -ECBM) combines geological CO 2 storage with methane recovery as part of the carbon capture and storage (CCS) system. CO 2 injection alters coal pore–fracture systems. Evaluating reservoir responses requires further parameterization of the structural information obtained fr...
