Abstract
The simulation of two-phase flow of fluids in porous media is a problem with very important practical applications. However the simulation time is so high for most computational methods available that it becomes prohibitive when the geometry is too large. The Young-Laplace Method (YLM) is a numerical method that predicts approximate results with much lower computational cost. Although YLM is indicated in the literature as a method with great predictive potential, it is still unclear in which situations it can be used with confidence. The geometry of the porous medium can be a crucial factor in determining when the method works well or not. In this work an investigation of the influence of the geometry of the porous medium on the results of the YLM is made. For this, several geometries, regular and irregular, are created, following ordering criteria in spatial distribution. For each geometry a simulation of two-phase flow is made with the YLM. Fluids saturation during the invasion are compared with expected results and with each other. Finally, it is shown that the geometry does not play a crucial role in the results of the YLM. The most important factor is that the Digital Rock is larger than the Representative Elementary Volume regardless of whether the geometry is organized or not.
