ABSTRACT:
Corrected oil relative permeability values for a core sample are determined from dynamic displacement measurements by the steps of plotting a ratio of oil rate output (q.sub.o) to calculated oil relative permeability values (k.sub.ro) vs. average water saturation (S.sub.w), determining if a straight line segment exists in areas of the plot corresponding to high average oil saturations, and if it does, extrapolating the straight line segment to the end of the plotted data, otherwise plotting a tangent curve from a beginning point of the plot, and correcting the calculated oil relative permeability values K.sub.ro by mulitplying the calculated values k.sub.ro by a ratio of a value on the q.sub.o /k.sub.ro plot to a value on the extrapolated line or constructed tangent curve at the same average water saturation value. The applied corrections eliminate distortions in the calculated oil relative permeability values k.sub.ro due to an end effect at the core sample which causes distortions in the dynamic displacement measurements.
