Technique determines average capillary pressure

A new technique estimates the average capillary pressure curve for a reservoir. Data from the Western Desert in Egypt were used to develop the correlations.Application of the method to four formations shows that, for each formation, the new equations predicted the laboratory-determined capillary pressure of core samples from the same reservoir with errors less than that of the J-function.Also, the general correlations predicted the laboratory-determined capillary pressures of core samples from three formations with errors less than that of the J-function.Average capillary pressureReservoir studies often require determination of an average capillary pressure, with the Leverett J-function b...
