Abstract
A composition for, and an improved process of, enhancing petroleum recovery from a petroleum reservoir by injecting into the reservoir a surfactant composition which includes at least one anionic surfactant component and a non-ionic surfactant component in which the components are proportioned to synergistically decrease the viscosity of emulsions in the reservoir over the effect of either component alone.
