Mathematical Modelling of Non-Equilibrium and Non-Linear Effects in Two Phase Fluid Filtration Flow

The physical nature of the non equilibrium processes in porous media is extremely diverse. These are phenomena of the phase redistribution in two phase flow resulting in the time dependence of the phase permeabilities, the phase interflow in micro heterogeneous media. The noted phenomena mostly govem the integral performance of the displacement of immiscible liquids. This paper addresses some the issues involved.
