  • SAGD steam trap control
    Patent number: 10731449
    Abstract: Methods and systems related to SAGD injection and/or production wells that utilize flow distribution control devices. Additionally, methods and systems using limited vertical spacing separating the wells are described. These methods and systems improve steam assisted gravity drainage (SAGD) oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.

  • Producer snorkel or injector toe-dip to accelerate communication between SAGD producer and injector
    Patent number: 9033039
    Abstract: Methods and systems relating to steam assisted gravity drainage (SAGD) utilizing well pairs that are at least initially in fluid communication through drilled bores toward their toe ends. At least one of a horizontal injection well and horizontal production well of such a well pair includes a hooked length toward toe ends of each other connecting said injection well and said production well. The methods and systems improve SAGD oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.

  • RADIAL FISHBONE SAGD
    Publication number: 20140345855
    Abstract: The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. A central wellpad originates injector and/or producer wells, arranged in a radial pattern, and either or both provided with multilateral wells, thus effectively expanding the coverage.

  • FISHBONE SAGD
    Publication number: 20140345861
    Abstract: The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. Fishbone multilateral wells are combined with SAGD, effectively expanding steam coverage. Preferably, an array of overlapping fishbone wells cover the pay, reducing water use and allowing more complete production of the pay.
