Semi-empirically derived petrophysical and thermodynamical coefficients of permselective argillaceous matrices

An explicit determination of concentration correlations and auxiliary parameters for solution transport through argillaceous matrices may be paramount in assessing their phenomenological and petrophysical properties. Different models have been proposed for hindered transient transport of water and ions. Most of these models depend on solute permeability, solute diffusivity, and reflection coefficient of the matrix amongst other parameters. Some models can predict various parameters for simple ionic molecules well but few of these can be immediately extended to flow and transport of organo-macromolecular solutions without special modifications. This study examines macro- to micro-scale quantitative and mechanistic processes that may influence single- to multi-phase contaminant fate through geologic media.
