What is Rock Stress Impact on Gas Permeability about?
This study investigated how rock stress affects gas production from low-permeability reservoirs. Laboratory experiments showed that: 1) Increasing confining pressure on core samples reduces their permeability, with a greater proportional reduction for low-permeability cores compared to high-permeability cores. 2) The permeability reduction was incorporated into a mathematical model for reservoir gas flow. 3) Calculations using the model show that permeability reduction due to stress can significantly i
