A micellar slug for use in the recovery of oil, the slug containing a hydrocarbon, an aqueous medium, a surfactant, and a cosurfactant. The surfactant contains as an essential component an internal olefin sulfonate or sulfonates having 10 to 30 carbon atoms and an alpha-olefin sulfonate or sulfonates having 10 to 30 carbon atoms. This micellar slug has a sufficiently low interfacial tension, good salinity tolerance, hard-water resistance, ability to maintain the micro-emulsion against change in the composition of the micro-emulsion, and mobility controlled viscosity.
