ABSTRACT:
The recovery of residual oil which is found in subterranean reservoirs may be accomplished by utilizing an aqueous surfactant slug to reduce the interfacial tension between oil and water. An effective surfactant slug which may be used will comprise a mixture of: (1) from about 1 to about 10% of a sulfonate of a mixture of mono- and dialkyl-substituted aromatic hydrocarbon which has been obtained by the alkylation of an aromatic hydrocarbon with an olefinic hydrocarbon in the presence of a hydrogen fluoride catalyst; (2) a lower alkyl alcohol which possesses from about 3 to about 6 carbon atoms; and (3) a nonionic cosurfactant comprising an ethoxylated n-alcohol which possesses from about 12 to about 15 carbon atoms.
