This thesis is motivated by the fact that most of the oil reserves are in the third phase of their life and the amount of fossil fuel reserves that have not been explored is limited. Enhanced Oil Recovery (EOR) is a method to increase oil reserves by removing some oil that previously could not be extracted. For the formulation of the problem in this thesis is the calculation of discharge in the fluid through the pores. This study aims to determine the quantitative description of the multicomponent flow from the pore scale and the permeability calculation of the fluid passing through the porous medium. The research methodology used is a computational method based on the Finite Volume Method (FVM) with OpenFOAM software. After doing the simulation, it can be seen that the size of the resolution has an influence on the smoothness of the image. In the next simulation, it is found that the application of Archimedes' law is in accordance with his theory, where an object will float if the density of the object (in this case Fluid 1) is less than the density of the liquid (Fluid 2). And objects will sink if the density of the liquid (Fluid 2) is less than the density of the object (in this case Fluid 1). It is also found that the influence of the small-size resolution on the smoothness of the slope in the graph plotting the curve on the air-water system. Then there are the results of plotting position against time and also velocity against time at the branch that forms a 45? angle to the horizontal, and the horizontal pipe.
