CA 2549369

A thermal in-situ method and apparatus are provided for recovering hydrocarbons from subterranean hydrocarbon-containing formations such as oil sands, oil shale and other heavy oil systems. Recovery of viscous hydrocarbon by hot fluid injection into subterranean formations is assisted by using a specially designed wellbore with an active hydraulic seal, with a axial communication zone with multiple injection perforations separated from the production perforations by a moveable packer. In addition, a novel downhole thermal sensing apparatus is used to monitor and control oil production. A producing mechanism including pumping equipment lifts the produced oil from the central cavity to the surface.
