Title: Steady-state relative permeability measurements corrected for capillary effects

Abstract

A new method is presented which enables to interpret steady-state flow experiments eliminating efforts caused by the capillary end-effect. This is achieved by retaining the capillary term in the equations that are used to interpret the flow data. The standard experimental procedure has to be extended to include variations in both total flowrate and the ratio of phase flowrates. Consistent values of saturation and relative permeability of each phase are then calculated at the inlet end. Necessary modifications in laboratory procedures and influence of hysteresis are discussed and the theoretical development is exemplified by numerical simulation of coreflood experiments.
