ABSTRACT This invention relates to a method for recovering hydrocarbon from a subterranean formation which comprises sequentially injecting, through an injection well 7 a drive fluid or a gas or a gas/liquid mixture to drive the hydrocarbon from the formation to a producing well and a mobility control fluid of a surfactant/water mixture into the subterranean formation characterized by using an alkylated diphenyl sulfonate surfactant in the mobility control fluid. Using an alkylated diphenyl sulfonated in combination with an anionic polyoxyalkylated surfactant improves the foamability as well as the foam stability of the foaming surfactant, thereby enhancing the performance of the mobility control fluid in improving the sweep efficiency of the drive fluid in a gas flooding operation.
