CO2-ECBM: A Review of its Status and Global Potential [PDF]
, 2014 In 1998, the IEA Greenhouse Gas R&D Programme (IEAGHG) assessed the global potential for CO2 enhanced coal bed methane (CO2-ECBM) recovery and associated CO2 storage based on data from the one successful pilot project at the time in the San Juan Basin in

ACS Omega, 2023 The in situ stress plays a crucial role in variations in coal permeability, hydraulic fracturing behavior, and accordingly coalbed methane (CBM) productivity. As the depth increases, the effects of in situ stress will become more prominent. In the Shizhuang block, present-day stress magnitude and permeability of coals at depths >800 m were measured ...
