... and S 0 * is defined as follows: (6) S o ∗ = S o − S o r 1 − S o r In 1954, Corey proposed a straight line relationship between 1/P c 2 and normalised oil saturation, S o * based on his derivation for gas-oil capillary pressure curves: (5) 1...

... using imbibition capillary pressure curves. Unfortunately, for each drainage capillary pressure curve, there is a whole family of imbibition curves, depending on the point on the drainage curve that a particular part of the reservoir reached. In total some 54 core analysis reports (from 91 available...
