Gas flooding process for the recovery of oil from subterranean formations
Patent
·
OSTI ID:7053170
An improved method for recovering hydrocarbon from a subterranean formation is described comprising sequentially injecting, through an injection well, a drive fluid of 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/aqueous fluid mixture into the subterranean formation, the improvement in the method operating using one or more alkylated diphenyl sulfonates as the surfactant in the mobility control fluid.
