Abstract
We present a workflow to obtain the transport properties (Permeability, Surface by Volume and Tortuosity) of a porous medium by means of Random Walk Simulation (RWS)(Silva et al., 2017). A methodology that is able to extract the transport properties of the porous medium by random particle walking (Nakashima and Watanabe, 2002). The method that is initially described by Nakashima and Watanabe (2002) is applied by the author, in a sample of artificial rock, which is composed of a set of regular spheres, where the description of the obtained results showed very promising data. Later, Silva et al. (2017) validates this method, but now applied to real rock samples (Sandstone and Carbonate), because it has a simple implementation, the methodology requires a low computational cost and the results are expressive when compared to the already used tools in the area.
