Pore Network Modeling Study of Gas Transport Temperature Dependency in Tight Formations

Temperature's effects on rock permeability are ambiguous; both positive and negative correlations have been reported in the literature. Temperature can affect the geomechanical behavior of porous media, as well as influence the mode of fluid transport. Rocks are subject to deformation, compaction, and chemical alteration at elevated temperatures. Conversely, confined fluids can undergo augmented non-Darcian mechanisms. In this research, a multiscale, multiphysical study of temperature's effects on gas permeability in tight formations is presented.
