An important aspect of any enhanced oil recovery (EOR) process is the effectiveness of process fluids in removing oil form the rock pores at the microscopic scale. Capillary and viscous forces govern phase trapping and mobilization of fluids in porous media. Understanding the role of pore-level mechanisms is essential to the design of EOR process in oil-fields. In present study, we observed the pore-scale mechanisms of surfactant flooding and water-alternated-gas (WAG) scheme by using the porous plates.
