  • Remote steam generation and water-hydrocarbon separation in steam-assisted gravity drainage operations
    Patent number: 10815763
    Abstract: A Steam-Assisted Gravity Drainage (SAGD) method for recovering hydrocarbons from a reservoir can include generating steam and CO2 from feedwater, fuel and oxygen; transferring a steam-CO2 mixture comprising at least a portion of the steam and at least a portion of the CO2, to a proximate SAGD injection well; injecting the steam-CO2 mixture into the SAGD injection well; obtaining produced fluids from a SAGD production well underlying the SAGD injection well; transferring the produced fluids for separation proximate to the SAGD production well; separating the produced fluids into a produced gas and a produced emulsion; transferring the produced emulsion for separation proximate to the SAGD production well; separating the produced emulsion to obtain a produced hydrocarbon-containing component and produced water; supplying at least a portion of the produced water as at least part of the feedwater; and supplying the produced hydrocarbon-containing component to a central processing facility.
    Type: Grant
    Filed: February 6, 2019
    Date of Patent: October 27, 2020
    Assignee: Suncor Energy Inc.
    Inventors: Andrew Donald, Todd Stewart Pugsley, Gary L. Bunio, Ian Donald Gates
