Gas drainage performance evaluation in coal under non-uniform stress with different moisture content: Analysis, simulation and field verification
Fuel（2021）
Abstract
•Built a one-way coupling process for a geomechanical and multi-physics simulator.•Simulate the gas changes of coal reservoirs, under high overburden stress.•The differences of coal reservoirs with different moisture content were analyzed.•In-situ measurements of relative gas content validated the simulations.
