Two-phase immiscible flow through porous media

An experimental program was set up for the determination of capillary pressure and relative permeability relationships for porous materials. This information was used for testing the predictive capabilities of a mathematical model for two-phase flow through porous media. Two pieces of equipment were developed for this purpose. One was a variant of Hewitt's original mercury Porosimeter/Permeameter for the determination of capillary pressure curves and the non-wetting phase relative permeability curve for the case of a completely displaceable wetting phase (zero wetting phase residual saturation). A second apparatus, a liquid/gas permeameter was built to measure both wetting and non-wetting phase relative permeabilities in the drainage cycle.
