Experimental Study on the Permeability of Quartz Sandstone under Coupled Thermo-Hydromechanical Loading

This paper focuses on the influence of coupled thermo-hydromechanical processes on the permeability of quartz sandstone. The permeability has been studied under five different confining pressures, three different temperatures, and three fluid pressures. The experimental results exhibit that the permeability of quartz sandstone decreases with the increase of confining pressure while it increases with temperature and fluid pressure. The...
