The application of chemical products, particularly polymeric products, is undoubtedly one of the most helpful and effective alternatives for EOR processes and changes in oil mobility. Appropriate chemical products provide more favorable interfacial conditions to the flow of petroleum, reducing the interfacial tensions between water and oil, and therefore, increasing the miscibility of these two compounds, and allowing the oil to flow in the porous medium. In this context, ionic compounds and particularly ILs are proving to be important auxiliaries in the performance of chemicals used for this application, particularly in extreme conditions of temperature and salinity.
