  • Patent number: 7740062
    Abstract: A system and a method for recovering hydrocarbons from a reservoir containing hydrocarbons, by in-situ combustion. The system includes a primary liquid production wellbore having a substantially horizontal primary production length extending through the reservoir, a vent well in fluid communication with the reservoir at a venting position which is relatively higher in the reservoir than the primary production length, an injector apparatus in fluid communication with the reservoir along an injection line in the reservoir which is relatively higher in the reservoir than the primary production length and relatively lower in the reservoir than the venting position, and an injection gas source connected with the injector apparatus.
    Type: Grant
    Filed: January 30, 2008
    Date of Patent: June 22, 2010
    Assignee: Alberta Research Council Inc.

  • Patent number: 6257334
    Abstract: A pair of vertically spaced, parallel, co-extensive, horizontal injection and production wells and a laterally spaced, horizontal offset well are provided in a subterranean reservoir containing heavy oil. Fluid communication is established across the span of formation extending between the pair of wells. Steam-assisted gravity drainage (“SAGD”) is then practised by injecting steam through the injection well and producing heated oil and steam condensate through the production well, which is operated under steam trap control. Cyclic steam stimulation is practised at the offset well. The steam chamber developed at the offset well tends to grow toward the steam chamber of the SAGD pair, thereby accelerating development of communication between the SAGD pair and the offset well. This process is continued until fluid communication is established between the injection well and the offset well.
