A diffuse layer model for hydrocarbon mass transfer between pores and organic matter for supercritical CO2 injection and sequestration in shale
TL;DR: In this paper, a pore-kerogen diffuse layer (PKDL) model was proposed for mass transfer between kerogen matrix and pores (inorganic pores and organic pores). Mathematical models for hydrocarbon mass transfer in spherical and cylindrical shaped rocks were derived.

The Permeability Of Porous Media To Liquids And Gases
TL;DR: The standard procedure for determining the permeability of porous media according to APZ Code No. 27 (first edition, October 1935) is based on the fundamental assumption that, as long as the rate of flow is proportional to the pressure gradient as mentioned in this paper.
