Abstract:
This invention relates to a foam-forming composition and method of use thereof for enhanced oil recovery. Said foam-forming composition comprises an anionic sulfonate surfactant wherein the anionic sulfonate surfactant is biodegradable and has low aquatic toxicity. The method for recovering oil from a reservoir comprises the periodic injection of gas and said foam-forming composition into the reservoir and contacting the oil in the reservoir with the foam so as to assist in the recovery of oil from the reservoir.
