A Stress-Induced Permeability Evolution Model for Fissured Porous Media
https://orcid.org/0000-0002-2885-5620
Abstract A unified permeability evolution model is proposed to capture the evolution of permeability induced by stress. This model is formulated within a conventional permeability–porosity power function, with special attentions being paid to the effects of shear deformation-induced tortuosity and compaction-induced closure of fissures through a permeability resistance parameter. This model contains a small amount number of parameters, which can be calibrated based on conventional experiments. The proposed model is validated through comparison between model simulation and experimental results for sandstones under a wide range of confining pressures. Good performance demonstrates the capability of the proposed permeability evolution model.
