A process for the recovery of oil from a subterranean oil reservoir involving the injection of an aqueous alkaline solution to neutralize organic acids in the reservoir oil to form surfactants in situ. This solution contains sufficient alkaline agent to impart a pH within the range of 11.5 to 13 and a monovalent salt within the range of 0.5 to 2.0 weight percent. The initial aqueous alkaline slug may be followed by a second alkaline slug containing a thickening agent.
