Computation of Drainage and Imbibition Capillary Pressure Curves from Centrifuge Experiments

ABSTRACT In this paper new methods to compute capillary pressure curves from centrifuge are developed for both drainage and imbibition. The methods are applied to experimental data. Results show that accurate determination of drainage capillary pressure curve can be obtained and negative capillary pressure in imbibition and residual oil saturation are also determined.
