Abstract

Two-phase flow in porous media is encountered in many processes such as enhanced oil recovery (EOR). Understanding the behavior of the flow at the pore scale is crucial for the optimal design of reservoir management and has been studied by many researchers for decades. In this study, we going to use an open-sourced multiphase Darcy-Brinkman approach to simulate two-phase flow for a complex pore network, which includes both solid-free regions and porous matrices in OpenFOAM. The fluid properties modeling is modeled for oil drainage systems, in which the investigation measures the main factor that affects the fluid behavior in a complex pore network, mainly focused on oil-water concentration, viscosity, Reynolds number, and capillary pressure. The main results indicate that fluid properties have an important impact on oil drainage, by reducing the volume of oil recovery due to the presence of the solid region. This study can be used to reproduce the direct numerical simulation results accurately to explain different mechanics in fluid displacement at the reservoir scale.
