ABSTRACT:
This invention relates to the use of superheated water as a heat carrier to melt or reduce the viscosity of a solid or semi-liquid hydrocarbon located in an underground deposit. Steam is injected in one conduit and water is injected in a second conduit. Steam is condensed and mixed with the injected water in an underground mixing chamber under sufficient pressure to maintain the resultant superheated water in the liquid phase.
