ABSTRACT:
A process for recovering oil from a subterranean reservoir in which a slug comprising a hydrocarbon-in-water emulsion together with a small amount of surfactant injected into the formation via an injection well is forced through the formation and oil is recovered via a production well penetrating the formation. In this process an emulsion slug is employed in which the surfactant concentration is tapered by increasing the concentration of the surfactant either incrementally, gradually or by any other convenient method during the slug injection time.
