ABSTRACT To investigate the hydraulic fracturing mechanism of high‐fluid wells in the Yangquan mining area, coal seams from the Xinyuan and Xinjing mines were selected as research subjects. Experiments were conducted using the TCQT‐III low‐permeability coalbed gas‐phase displacement and production enhancement apparatus, along with the FINESORB‐3120 ...

Potential for CO2 sequestration and enhanced coalbed methane production in the Netherlands [PDF]
This study investigated the technical and economic feasibility of using CO2 for the enhanced production of coal bed methane (ECBM) in the Netherlands. This concept could lead to both CO2 storage by adsorbing CO2 in deep coal layers that are not suitable ...
