Abstract: A three component surfactant system usable in the presence of from about 1,500 to about 12,000 parts per million polyvalent ions, such as calcium and/or magnesium, and a method of using said surfactant system for recovering petroleum from subterranean formations, said surfactant system comprising a water soluble salt of an alkyl or alkylaryl sulfonate anionic surfactant plus a water soluble salt of an alkyl polyethoxy sulfate anionic surfactant plus a nonionic surfactant such as a polyethoxylated alkyl phenol, a polyethoxylated aliphatic alcohol or a fatty acid mono- or dialkanolamide.
