Subsurface safety valve deployable via electric submersible pump

摘要

Certain aspects and embodiments of the present invention are directed to a subsurface safety valve disposed in a wellbore through a fluid-producing formation. The subsurface safety valve can include a closure mechanism. In some embodiments, the subsurface safety valve can be coupled with an electric submersible pump. The subsurface safety valve coupled to the electric submersible pump can be positioned in a passageway defined by a tubing string via a power cable coupled to the electric submersible pump. In some embodiments, the subsurface safety valve can include at least one terminal. The at least one terminal can form an electrical connection between the subsurface safety valve and the electric submersible pump. The subsurface safety valve can receive power from the electric submersible pump via the electrical connection.

1. A closure system configured for being disposed in a wellbore through a fluid-producing formation, the closure system having a subsurface safety valve comprising:
a closure mechanism configured to be positioned in a passageway defined by a tubing string, wherein the closure mechanism is configured to prevent a flow of fluid to a portion of the passageway that is closer to a surface of the wellbore than the closure mechanism; a first coupling mechanism configured for selectively coupling and decoupling the subsurface safety valve with an electric submersible pump; a second coupling mechanism configured for coupling the surface safety valve to the tubing string separately from the electric submersible pump; and at least one terminal configured to form an electrical connection between the subsurface safety valve and an electric submersible pump, wherein the subsurface safety valve is configured to receive power via the electrical connection.
