Abstract

Water-in-oil emulsions are injected into subterranean formations to divert steam from steam-swept zones around cyclic steam stimulation wells or between injection and production wells in steam floods.
The emulsions divert hot fluids to cold unswept zones containing high oil saturations, thereby increasing the net oil recovery.
