Abstract

Conceptual models have been developed to identify the effects of solid deformation on the changes in rock permeabilities for fractured media, intact media, and fractured porous media subjected to external loads. Finite element schemes were established with embedded correlations between induced strain and modified permeability to simulate the coupled flow-deformation behavior of reservoir rocks tested in the laboratory. Rock specimen permeability was evaluated through comparison between analytical solution and numerical calculation using geometric factors. Numerical simulation of the tests revealed a strong correlation between permeability modification and the induced stress. The simulation also indicated that physical properties of the porous media are significantly altered by mechanical effects.
