Abstract: The development of a mathematical algorithm to simulate the displacement of a resident fluid using a displacing one in a saturated anisotropic porous media is shown in this work. The algorithm was included in the simulator developed by the present authors in previous works to represent the anisotropic distribution of the porous media properties and the fluid injection [Ramirez A et al. Mathematical simulation of oil reservoir properties. Chaos, solitons & Fractals 2008;38:778–88, Ramirez A et al. Simulation of uncompressible fluid flow through a porous media. Chaos, Solitons & Fractals 2009;39:1753–63] in a nested loop to analyze the participant nodes in the transport process and calculate the volumes of the resident and new fluids. The new routine developed takes in count the mobility of both fluids. Additionally experimental fluid displacement tests were done using heavy oil from Mexican reservoirs as a resident fluid in sand berea cores. The injection of new fluids in natural oil reservoirs is a part of the Enhanced oil recovery (EOR) methods used to improve the oil displacement and increase production after the primary stage of the oil recovery has been finished. Water is an available and economical resource to be used as a displacing fluid due to many of the producers (off-shores) of the oil industries are placed in the sea near the coast.
