  • System and method for the recovery of hydrocarbons by in-situ combustion
    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.

  • Hollow-fiber membrane device including a split disk tube sheet support
    Patent number: 6224763
    Abstract: A hollow fiber membrane device adapted for bore side feed includes a split annular disk as a tube sheet support. The device may be assembled without integrating tube sheet support means into the hollow fiber bundle and tube sheet combination and without in situ tube sheet formation.
