ABSTRACT:
Waterflooding process for the recovery of oil from a subterranean formation in which at least a portion of the injected water preferably may contain a preferentially oil-soluble alcohol, a sulfobetaine, a quaternary ammonium compound containing at least one long chain hydrocarbyl group and a quaternary ammonium compound with short chain hydrocarbyl groups. This formulation serves both as a surfactant and a mobility control agent.
