Abstract
A method of enhancing oil recovery from a carbonate reservoir containing a hydrocarbon mixture includes injecting the carbonate reservoir with a sea-water solution comprising a citric acid-based additive to displace the hydrocarbon mixture from the carbonate reservoir thereby forming a hydrocarbon mixture containing sea-water mixture; and separating the hydrocarbon mixture from the hydrocarbon mixture containing sea-water mixture to recover the hydrocarbon mixture. The citric acid-based additive is present in the sea-water solution at a concentration of 1 to 1000 parts per million based on a total number of parts by weight of the sea-water solution. Particles of the citric acid-based additive are adsorbed on surfaces of the carbonate rocks in the carbonate reservoir.
