Material Composition, Pore-Fracture Structure, and Methane Adsorption–Desorption Characteristics of Coal Reservoirs in the Yingcheng Formation, Longjiapu Mining Area, Southeastern Songliao Basin
Low-rank coalbed methane (CBM) resources are abundant in China, but their commercial development is limited by insufficient understanding of the coupled controls of coal material composition, pore-fracture structure, and desorption behavior in deeper low- to medium-rank bituminous coals. This study focused on the No. I...
