Permeability intrinsic permeability

WebIntrinsic permeability or permeability (k) is a quantitative property of porous material and is controlled solely by pore geometry (Richards, 1952). Unlike saturated hydraulic … WebThe proposed model captures well the intrinsic permeability decrease associated to the elastic compression of the natural pores, followed by the permeability jump due to crack opening. The modeling framework can be adapted to any rock constitutive model, including thermo-hydro-chemo-mechanical couplings. Applications may be found in energy ...
