摘要

One way of obtaining water-oil relative permeability curves is from co-injection (of water and oil)experiments at steady-state (SS) condition. The two-phase Darcy Law can be used to calculate the relativepermeability directly only when water saturation is constant along the core. However, the capillary endeffect (CEE) causes water accumulation or depletion at the end of the core depending upon the wettability.This work describes an improved method for correcting for this effect by modifying the "intercept method"initially proposed by Gupta and Maloney (2014).
