The capillary pressure at each point along the plug at hydrodynamic equilibrium is obtained from Equation (1). In the above equation, P c (r) is the capillary pressure at any given radial position, Δρ ...

El-Khatib showed that Equation 2 represents the capillary pressure curves. 4 He used the a and b parameters, as well as the tortuosity and the irreducible water saturation, to develop a modified J ...
