    摘要: Fluids injected into a carbonate reservoir formation during Enhanced Oil Recovery (EOR) may include a foaming mixture that includes a zwitterionic surfactant, an omega-3-acid ethyl ester, and aqueous salt solution. The omega-3-acid ethyl ester may include eicosapentaenoic acid ethyl ester, docosahexaenoic acid ethyl ester, or combinations thereof. The foaming mixtures may be incorporated into methods for enhancing hydrocarbon recovery in a carbonate reservoir formation. The methods may include introducing the foaming mixture to the carbonate reservoir formation such that any hydrocarbon present in the carbonate reservoir formation is displaced by the foaming mixture and is recoverable from the carbonate reservoir formation.
