Abstract

Adequate presentation of the initial oil saturation cube during geomodelling and reservoir simulation is one of the most critical tasks, as it provides the basis for estimating the initial and remaining oil reserves in a productive formation. This paper analyzes the existing methods for generating the initial oil saturation cube during reservoir simulation, highlighting their advantages and disadvantages. The study provides a detailed discussion of various methods of the initial oil saturation distribution based on well log interpretation data, as well as principles of the initial oil saturation cube generation using the Leverett J-function. A comparative evaluation of the results from generating the initial oil saturation cube by these methods was performed. It has been found that considering such factors as reservoir porosity and permeability, and capillary forces enables generating a more physically representative initial oil saturation cube.
