Abstract

Estimation of oil saturation in reservoir characterization is important for the solution of geological problems. We present an oil-saturation factor technique based on the Leverett J function. Such an approach allows oil saturation prediction in absence of holes on the basis of capillarimetric investigations of core material. The good agreement between the results of oil-saturation computation and the conventional Archie-Dahnov equations proves the validity and applicability of the suggested technique.
