Title: N n-disubstituted amide cosurfactants in enhanced oil recovery processes

Abstract

A surfactant system useful for oil recovery consisting essentially of a NaCl brine, a hydrocarbon sulfonate surfactant, such as a petroleum sulfonate, and a cosurfactant such as a N,N-disubstituted amide. In another embodiment, a C/sub 1/ to C/sub 8/ alcohol is additionally present as a cosurfactant.
