Abstract
In petrophysics the great scale of the problems requires robust algorithms for numerical simulations. In this article an adaptation of the well known Level Set Method is proposed with the goal of finding a well resolved Signed Distance Function. A new method of initialization and reinitialization is used, it involves the use of Euclidean Distance Transform (EDT). The EDT is also used as a way of finding a velocity function that, accurately, represents the steady state flow through a rock in cases where pressure driven forces are more relevant than surface forces. The results of simulations involving the EDT velocity function will be compared with other simulations that used velocity functions obtained with more well known algorithms, like Lattice Boltzmann Method’s (LBM) and the Maximum Subscribed Sphere (MSS).
