Abstract
Recently, due the Brazilian Pre-Salt exploitation there has been an increase in the study of carbonate, karst reservoirs. These geological formations contain vugs, cavities and caves, which are voids of different length scales. Traditionally, the mathematical model that represents the flow of fluids in oil reservoirs is based on the Darcy’s equation, however, this model may not represent well situations in which it is necessary to deal with carbonate (karst) reservoirs due to the presence of free flow regions. In the Stokes-Brinkman model there is a smooth transition between the free flow region and the Darcy´s flow regime. In this paper, we implement a finite difference numerical discretization to solve Stokes-Brinkmam equations assuming single phase flow in heterogeneous carbonate karstic reservoirs. In order to verify the accuracy of our implementation we solve some simple but representative problems found in literature.
