Abstract: The present invention relates to a method to enhance oil recovery from a hydrocarbon reservoir. One aspect of the invention includes injecting low-salinity water into the reservoir followed by the injection of a surfactant diluted in low-salinity water, and alternating the injections of the low-salinity water and the surfactant diluted in the low-salinity water. A gas is then injected into the reservoir. The invention improves the effectiveness of the surfactant and the gas by reducing the salinity of the reservoir by injecting low-salinity water into the reservoir.
