A CRITICAL COMPARISON OF KRIGING, FRACTAL AND INDICATOR KRIGING TECHNIQUES

Abstract

Geological and geostatistical characterisation of reservoir heterogeneities is becoming increasingly popular for the maximisation of oil production from existing oil fields. Many geostatistical techniques, such as kriging, fractal and indicator kriging, have become available either in published or commercial forms. There is, however, little information available and even fewer comparisons between methods to guide users in this area. This paper compares oil recovery performance based on different geostatistical models generated by kriging, fractal and indicator kriging techniques with a constructed synthetic model typical of a fluvial-deltaic sequence.
