CO2 enhanced flow characteristics of naturally-fractured bituminous coals with N2 injection at different reservoir depths

Zhang, XG; Ranjith, PG; Li, DY; Perera, MSA; Ranathunga, AS; Zhang, BN [Article-Full-text]

Coal matrix swelling caused by the adsorption of CO2 during the CO2-ECBM process is the major reason for the decline of coal permeability and CO2 injectivity. Measures to recover this permeability reduction are of significant ...
Variation of mechanical properties of bituminous coal under CO2 and H2O saturation

Zhang, XG; Ranjith, PG; Ranathunga, AS; Li, DY [Article-Full-text]

CO2 injections into coal seams can boost the recovery of coalbed methane (CBM), while simultaneously sequestering a greenhouse gas. However, alteration of the mechanical attributes of coal is observed during CO2 injection. ...
