ABSTRACT:
In accordance with the present invention, oil is recovered from a subsurface earth formation by injecting into the subsurface formation an aqueous surfactant system containing a polyvalent metal carboxylate, as a surfactant, a cosurfactant and an electrolyte in concentrations and proportions to form multiphase system with the reservoir oil, thereafter, injecting into the earth formation a drive fluid to drive the multiphase system through the reservoir and displace a significant amount of the reservoir oil and withdrawing the thus displaced oil from the subsurface earth formation. A novel aqueous surfactant system, adapted to thus recover oil from a subsurface formation, comprises a polyvalent metal carboxylate, such as calcium isosteareate, as a surfactant, and an alcohol having at least five carbon atoms, as a cosurfactant, and an electrolyte, such as sodium chloride, in proportions which form a multiphase system with the reservoir oil.
