Pressure-Controlled Drainage Strategy for Deep Coalbed Methane Wells Considering Stress Sensitivity
China’s deep coalbed methane (CBM) resources hold significant development potential, yet their commercial exploitation remains hindered by four interrelated reservoir challenges: substantial burial depth, elevated in situ stress, ultra-low matrix permeability, and pronounced stress-dependent permeability decline. These...
