Abstract

Concepts of percolation theory, universal scaling laws, thin film flow and fractal geometry are used to develop realistic expressions for the capillary pressure and relative permeability curves for the case of two-phase (oil/water) flow in natural porous media (e.g. sedimentary rocks, soils, etc.). Approximate analytical expressions are derived for drainage processes in water-wet porous media, taking into account the gradual changes of fluid distribution and effective conductivities in the pore network and fractal roughness porosity.
