Disclosed is a novel surfactant fluid and an oil recovery method using the fluid for recovering oil from subterranean formations thereof by surfactant waterflooding process. The fluid comprises water and at least one surfactant, preferably including an alkylpolyalkoxyalkylene sulfonate or an alkylarylpolyalkoxyalkylene sulfonate and as an additive for reducing the rigidity of the interfacial film, a silicapolydialkylsiloxane such as a silica-polydimethylsiloxane. Reduction in rididity of the interfacial film occupied by surfactant molecules of which the hydrophobic portion is dissolved in the oil phase and the hydrophilic portion is dissolved in the aqueous phase, improves the effectiveness of the surfactant fluid for recovering oil from subterranean formations.
