Abstract
The present invention relates a method to estimate representative elementary volume (REV) in a sample of porous media wherein the sub-volume selected is a better approximation of the elementary volume than existing methods. REV in a sample of porous media such as rock can be defined wherein the REV is selected with respect to the expected direction of fluid flow through the porous media. The method can quantify how good is the digital representation of a rock and how accurate a description of a fluid flow through Darcy's law will be, and allows the evaluation of different length scales in different directions for the REV and an assessment of the anisotropy of the pores structures when the method is applied in different directions. The method also can determine a robust criteria to understand when a trend of porosity-permeability breaks down due to an insufficient size of the subsample.
