A parametric model is developed to describe relative permeability-saturation-fluid pressure functional relationships in two- or three-fluid phase porous media systems subject to monotonic saturation paths. All functions are obtained as simple closed-form expressions convenient for implementation in numerical multiphase flow models. Model calibration requires only relatively simple determinations of saturation-pressure relations in two-phase systems. A scaling procedure is employed to simplify the description of two-phase saturation-capillary head relations for arbitrary fluid pairs and experimental results for two porous media are presented to demonstrate its applicability. Extension of two-phase relations to three-phase systems is obtained under the assumption that fluid wettability follows the sequence water > nonaqueous phase liquid > air.
