  • Patent number: 10260324
    Abstract: Systems and method for producing hydrocarbons from a subterranean well include a combined product tubular extending into the well, a gas production tubular in fluid communication with the combined product tubular and a fluid production tubular in fluid communication with the combined product tubular. A jet pump is located a junction of the tubulars. An electrical submersible pump is in fluid communication with the fluid production tubular. A cyclone separator is located within the well and has a rotating screw with thread surfaces open to an inner diameter surface of the well. The thread surfaces are angled to direct a liquid stream axially downward and radially outward towards the inner diameter surface of the well, and to direct a gas stream to a lower end of the gas production tubular.
    Type: Grant
    Filed: October 27, 2016
    Date of Patent: April 16, 2019
    Assignee: Saudi Arabian Oil Company

  • Patent number: 10260323
    Abstract: Systems and methods for producing hydrocarbons from a subterranean well include a fluid production tubular and a gas production tubular extending separately into the well. An electrical submersible pump is in fluid communication with the fluid production tubular. A cyclone separator is within the well. The cyclone separator has a rotating screw with thread surfaces open to an inner diameter surface of the well. The rotating screw is positioned between a lower end of the gas production tubular and the electrical submersible pump. The thread surfaces are angled to direct a liquid stream axially downward and radially outward towards the inner diameter surface of the well. A central passage extends through the rotating screw and is oriented to direct a gas stream towards the lower end of the gas production tubular.
