    Abstract: Wettability alteration of the oil-wet reservoir rocks to the water-wet state is an important factor for enhanced oil recovery (EOR). One of the main challenges of applying nanoparticles for wettability alteration is related to the colloidal stability and poor adsorption of the nanofluids in the harsh conditions of the reservoirs. In the present wor... Show More

    Abstract: The use surfactant chemicals to improve oil recovery has been practiced both at laboratory and field scale levels. The results obtained have revealed an incremental oil recovery with surfactant injection. Surfactant injection aims at reducing the interfacial tension (IFT) between oil-water systems resulting to increase in the microscopic sweep of t... Show More
