Determination of Three-Phase Relative Permeabilities From Displacement Experiments

Abstract

Summary We describe and demonstrate a method for the determination of three-phase relative permeability functions at reservoir conditions. Two- and three-phase displacement experiments are conducted on a low-permeability chalk sample, and estimates of the three-phase relative permeability and capillary pressure functions are obtained. We also calculate three-phase relative permeabilities with the Stone predictive model, and we evaluate them by simulating the experimental data.
