  • Publication number: 20220025738
    Abstract: A fallback prevention valve apparatus, system and method is described. An electric submersible pump (ESP) fallback prevention system includes an ESP assembly positioned in a downhole well, the ESP assembly including production tubing extending between a centrifugal pump and a surface of the downhole well such that during operation of the ESP assembly production fluid flows upward from the centrifugal pump through the production tubing to the surface, the production tubing including a fallback valve actuatable by the flow of production fluid, the fallback valve actuatable between an open position, wherein production fluid flowing upward through the fallback valve actuates the fallback valve into the open position, and a closed position, wherein production fluid flowing downward through the fallback valve actuates the fallback valve into the closed position, the closed position blocking sand carried by the production fluid from falling into the centrifugal pump.

  • Publication number: 20210233679
    Abstract: A reinforced power cable system for use with an electric artificial lift system is provided. The system includes an electric artificial lift system. The system also includes a power cable that provides power to the electric artificial lift system from a surface of a well. The power cable includes at least one conductor positioned within a cable jacket and a braided tube with an open-weave of a reinforcing component installed around the cable jacket. Additionally, the power cable includes a coil tube welded around the braided tube.

  • Patent number: 10858925
    Abstract: A crossover system, method and apparatus for an electric submersible pump (ESP) gas separators. A crossover of an ESP gas separator includes a first helical pathway for higher density fluid that extends at an angle of 10° to 40° from a horizontal plane through the crossover, the first helical pathway fluidly coupled to a spider bearing including crescent shaped vanes that remove rotational momentum from the higher density fluid, a second helical pathway for lower density fluid that tangentially intersects a crossover jacket, the first helical pathway and the second helical pathway defined by a channel having teardrop shaped openings in the crossover jacket that define channel exit ports venting to a casing annulus, and teardrop shaped openings in a crossover skirt that define a channel entrance, where the first helical pathway is around the channel and the second helical pathway is through an inside of the channel.

  • Patent number: 10428630
    Abstract: A method of live well artificial lift completion includes hanging an umbilical on a wellhead of a live well, the umbilical fluidly coupling a production pump to a well surface and electrically coupling an electric motor to a surface power source, the electric motor powering the production pump. The umbilical includes coiled tubing surrounded by a jacket. The umbilical also includes power cables extruded inside the jacket to form a smooth jacket outer surface. The method also includes creating a pressure seal inside the umbilical during deployment of the umbilical into the live well, the pressure seal inside the umbilical created using a blowout plug positioned to block a discharge of the production pump. The method further includes forming an annular pressure seal during deployment of the production pump to obtain well control, the annular pressure seal formed using an annular bag coupled to the wellhead.
