To address engineering challenges from large fluctuations in gas concentration and low CH4 recovery during the development of CO2-rich coalbed methane in the southern Junggar Basin, high-volatile bituminous coal samples were selected. Adsorption–desorption experiments were conducted separately with pure CH4, pure CO2...

As an important unconventional natural gas resource, coalbed methane (CBM) plays a significant role in safeguarding national energy security. The Yushe-Wuxiang block, located in the central-eastern Qinshui Coalfield, is rich in CBM resources; however, its coal reservoirs are characterized by low permeability and strong...

The coupled effect of in situ temperature and stress complicates the permeability evolution of coal reservoirs, which restricts the exploration and evaluation of deep coalbed methane (CBM). Two high-rank coal samples were collected from the Sihe (SH) and Zhaozhuang (ZZ) mining areas, and multi-gradient coupled temperat...
