Evaluation of gasification agent strategies for underground coal gasification in post-ECBM reservoirs: A coupled thermo-hydro-chemical numerical simulation approach

Implementing underground coal gasification (UCG) in post-ECBM reservoirs, namely coal reservoirs after CO 2 -enhanced coalbed methane (CO 2 -ECBM) recovery, provides a potential pathway for residual energy recovery. However, the pre-existing CO 2 -rich environment alters reservoi...
