Pore space heterogeneity evaluation of 3D digital rock samples using multifractals

Pore structure heterogeneity is a critical parameter controlling physical behavior of rock. Multifractal study, supported by scale-invariant property of porous media, is a well-known method that can capture heterogeneity variations in pore structures. The aim of this study is to use such a method in 3D digital rock samples to evaluate and compare their heterogeneity.
