Viscous oil may be recovered from subterranean, viscous oil-containing formations by injecting a heated aqueous fluid into the formation to raise the temperature of the viscous petroleum, and to displace it toward a remotely located production well. The heated aqueous fluid, which may be liquid, gas ...

A system for recovery of oil, particularly viscous oil, from subsurface formations penetrated by highly deviated or horizontal bore holes by circulating therethrough a heated fluid. The heated fluid is circulated through a flexible conduit which is pulled into the bore hole by thrust generating mean ...
