Permeability (earth sciences)

TL;DR: In this paper, the authors focused on the characterization of the overall pore size distribution in tight gas sandstones originating from distinct Brazilian fields, as well as fluid flow circulation described by single-phase permeability.

TL;DR: In this paper, a boundary-layer solution for natural convection in rectangular enclosures containing a porous medium is presented, which is based on the modified Oseen technique, and the flow field is found to be governed by the parameter E = Ra 0 Da / A.

TL;DR: In this article, an analytical model was proposed to represent the anisotropic permeability evolution of coal due to effective stress change and gas sorption, and this model captured both mechanical properties and gas-sorption-induced directional strains.
