Two-phase flow in porous media: Property identification and model validation



The experimental design and analysis of two-phase dynamic displacement experiments are investigated, with particular attention to incorporating measured saturation distributions. Pressure drops and saturation distributions measured with displacement experiments using multiple flow-rate injection rates can provide accurate estimates of relative permeability and capillary pressure functions over broad ranges of fluid saturations. Successful reconciliation of measured saturation distributions and pressure drops establishes an experimental validation of the Darcy model for two-phase flow in porous media.
