Lithology-Dependent J-Functions and Relative Permeabilities

ABSTRACT This paper demonstrates a technique of using log data coupled with lithology dependent porosity-permeability transforms to calculate facies-dependent Leverett J-functions for the Hadriya reservoir. A comparison of initial water saturation profiles from formation analysis logs versus profiles from a single global J-function and facies-specific J-functions are presented. These facies dependent J-functions were then used to compute facies specific imbibition and drainage relative permeabilities for both the wetting and non-wetting phase.
