Influence of CO2 injection timing on enhanced coalbed methane recovery using thermo-hydro-mechanical coupled model

Delayed CO2 injection can prevent premature CO2 breakthrough to production wells during CO2 enhanced coalbed methane (CO2-ECBM) recovery. Currently, the influence of CO2 injection timing on CO2-ECBM recovery is unclear. In this paper, the thermo-hydro-mechanical (THM) coupled model was established t...
