Modification of Microstructural and Fluid Migration of Bituminous Coal by Microwave–LN2 Freeze–Thaw Cycles: Implication for Efficient Recovery of Coalbed Methane
To improve the efficiency of coalbed methane and recoverability of reservoirs, enhanced fracturing technology is usually required to improve the low porosity and permeability status of coal reservoirs. As a fe...

Gas Pressure Prediction Model for Carbon Dioxide Injection in a Large-Scale Coal Matrix Experiment
Carbon dioxide injection, gas flow, and adsorption of CO2 in a coal matrix are modelled by a large-scale physical experiment. The process primarily comprises an increase in the gas pressure from an unsaturated to...
