ABSTRACT A process useful for recovering surfactant and oil of low water content in surfactant flood oil recovery projects is disclosed. A produced oil in water emulsion is treated with brine and partitioning agent, preferably isopropyl alcohol, by mixing and settling to form three phases, an oil phase containing a minor amount of surfactant, a partitioning agent phase containing most of the surfactant originally present in the produced emulsion, and a brine phase-containing a minor amount of alcohol.
