Abstract

The development and implementation of an unsteady-state pore-scale process simulator is described. The simulator is utilized to interpret a number of related laboratory gas-oil displacements performed at different values of interfacial tension (IFT). This proved to be essential in modeling and interpretation of the experimental results. The results demonstrate that it is extremely difficult to predict a priori the directional trend exhibited by relative permeability curves with varying IFT, unless all experimental quantities are reported.
