The evolution of permeability hysterisis in Indiana Limestone during application of isotropic confining pressures up to 60 MPa was measured by conducting one‐dimensional constant flow rate tests. These tests were carried out either during monotonic application of the confining pressure or during loading‐partial unloading cycles. Irreversible permeability changes occurred during both monotonic and repeated incremental compression of the limestone. Mathematical relationships are developed for describing the evolution of path‐dependent permeability during isotropic compression.
