Abstract
The study of fluid front in porous media in enhanced oil recovery is important. The purpose of this study is to simulate water flooding, and investigate the factors affecting the fluid front across a microfracture and simple porous media using Shan-Chen type of the Lattice Boltzmann Method (LBM). Various factors, including velocity and dynamic viscosity that define the capillary number and wettability are considered. Independently, the increase in velocity and dynamic viscosity ratio results in viscous fingering and its narrowness. Increasing the wettability of the displacing fluid decreases viscous fingering, and as a result, it makes the fluid move in piston form. The lowest sweep efficiency occurs when the displacing fluid has a neutral wettability. Simulation results show the strength and accuracy of Shan-Chen type of LBM in fluid front tracking in porous media in pore scale.
