Abstract
The transport properties (Surface to Volume ratio, Porosity, Permeability and Tortuosity) with the current simulations methods can be quick, but requires high computational cost. The article: "Estimate of transport properties of porous media by microfocos x-ray computed tomography and random walk simulation" (Nakashima & Watanabe, 2012) shows how to get these properties through the random walk. The technique requires little computational cost and gets good results. In this work is implemented the algorithm described by Nakashima & Watanabe (2012). The program is applied to a problem equivalent to those studied by the authors as a way of validating the implementation. After this,is done the study of digital rocks obtained by x-ray microtomography from reservoir rocks. The digital rocks have 1000^3 voxels and are described in Raeini, et al., 2017.
