  • ELECTRICALLY- POWERED SURFACE - CONTROLLED SUBSURFACE SAFETY VALVES
    Publication number: 20140144649
    Abstract: A subsurface safety valve system for a wellbore within a subterranean formation is described. The system can include a power source that generates power, and a delivery system disposed within the wellbore and electrically coupled to the power source. The system can also include at least one safety valve disposed within the wellbore and electrically coupled to the delivery system, where the at least one safety valve remains open while the at least one safety valve receives the power from the delivery system, and where the at least one safety valve closes when the at least one safety valve stops receiving power from the delivery system. The system can further include production tubing mechanically coupled to a distal end of the at least one safety valve, where the at least one safety valve shuts in a cavity within production tubing when the at least one safety valve closes.
