Tuning digital core analysis to laboratory results

Abstract

A method and computer system for performing simulation of a field having a subterranean formation. The method includes obtaining measured core sample data of a core sample retrieved from the formation, the core sample data measured by injecting fluid into the core sample, obtaining a digital rock model of the core sample describing a physical pore structure in the core sample, and obtaining a fluid model describing a physical property of the fluid. A digital core analysis (DCA) of the core sample is performed to generate a DCA simulation result and the DCA is tuned using the measured core sample data to reduce a difference between the DCA simulation result and the measured core sample data. The tuning is performed by adjusting, in response to the difference exceeding a pre-determined limit, a parameter of the DCA to generate an adjusted parameter and further performing the DCA to reduce the difference.
