Title: Micellar slug for oil recovery

Abstract

A micellar slug for use in the recovery of oil is described, the slug containing a hydrocarbon, an aqueous medium, a surfactant, and a cosurfactant. The surfactant contains as an essential component an alpha-olefin sulfonate having 10 to 26 carbon atoms and containing 0.1% to 15% by weight by weight of a disulfonate. This micellar slug has an excellent salinity tolerance and hard-water resistance. Furthermore, the micellar slugs of the present invention are capable of forming micro-emulsions having a sufficiently low interfacial tension and, therefore, can improve oil recovery efficiency.
