Abstract
The application of tertiary recovery methods to increase the recovery factor of oil fields, especially in heavy oil reservoirs, has increased considerably due to the efficiency of primary and secondary oil recovery methods do not be more than 30\%. Among these methods, the injection of chemicals can be cited. To apply these methods, it is important to understand the phenomenology of liquid-liquid displacement occurring within a porous medium. In this work, the influence of the viscosity ratio on tertiary recovery method was evaluated. Using an experimental approach, different Newtonian solutions were used to displace another Newtonian fluid that fills the pores of a specific porous medium. It was shown that the lower the viscosity ratio, the greater the displaced liquid fraction recovered.
