摘要：A well completion, and method for recovering heavy hydrocarbons or bitumenfrom a subterranean formation. The completion includes a well liner which lies in agenerally horizontal disposition within a hydrocarbon holding substrate to define themain or primary well. A secondary well which extends to the surface intersects the mainwell to communicate therewith. Said secondary well includes means to conduct a streamof hot stimulating fluid into the main well. A fluid impervious barrier or flow divertermeans positioned within the main well between the injection end and the production end,establishes a pressure differential across the barrier. The barrier urges stimulating agentinto the substrate at a desired location, thereby creating a heated path along which thebitumen emulsion flows toward the well's production end. Means is provided in thesecondary well to position the impervious barrier from one end of the main well to theother.
