  • Patent number: 12687086
    Abstract: A technique facilitates construction and operation of electric completion systems which may be used in the oil and gas industry. The technique is able to eliminate some or all hydraulic lines and replace them with electric lines. Depending on the application, the electric power may be provided via a surface-based power source and/or a downhole power storage/generation source. Corresponding completion components, such as control valves, subsurface safety valves, gauges, and/or other completion tools, are electrically operated via power and communication provided through the electric lines and/or wireless telemetry without the cost and complexity of hydraulic control lines and downhole hydraulic components.
    Type: Grant

    Date of Patent: July 21, 2026
    Assignee: Schlumberger Technology Corporation
    Inventors: Oguzhan Guven, David Lardy, Robert Krush
  • Patent number: 12624613
    Abstract: A screen is integrated with or connected to an electric flow control valve via a flow-through 3-way sub, wherein the 3-way sub comprises: a first connection configured to couple to the electric flow control valve; a second connection configured to couple to the screen; a third connection configured to couple to an inner string disposed at least partially within the screen; and one or more flow through ports configured to direct flow from the electric flow control valve to an annulus of the screen.
