Definitions

  • the upper portion of the production tree 43 is provided with a shutoff valve 48 and a quick connection 49, which allows for connecting a small production riser 50 between the production tree and a workover vessel (not shown) floating in the top of the water.
  • the conductor housing 124 is filled with dielectric material 127 through its upper end, which will surround the electric conductor 128 connected to the female terminal 122, the bleeding of air from the housing during the filling operation being permitted by the provision of a vent port 129 in the lower portion of the conductor housing.
  • the housing 124 is threadedly secured to a spelter socket 130 into which the cable 52 extends.
  • the steel strands of the cable are separated and spread apart in the spelter socket, after which the socket is filled through a port 131 with a resin 132 which firmly anchors the steel cable strands to the socket 130, and also the conductor housing 124 connected thereto.
  • the mechanical connector 32 is released from the hanger housing 21 and elevated, together with the Christmas tree 331 thereabove, to the drilling vessel, the bridging nipple 329 being removed from the tubing hanger 302 and the female portions 319, 321, 80, 79 of the electrical connector C being disconnected from the male portions 310, 315, 58 carried by the tubing hanger.
  • apparatus for conducting electric current to an electrically operated subsurface device disposed in a well bore hanger means at the top of the well bore; a landing head removably supported in said hanger means; first electric conductor means in said landing head having a first terminal; a support shiftable into and from operative relation to said landing head; second electric conductor means carried by said support and having a second terminal adapted to be brought into and from contact with said first terminal in response to movement of said support relative to said landing head; coengaging orienting means on said landing head and hanger means placing said first electric conductor means in a position aligned with said second electric conductor means; said shiftable support and second conductor means being movable from obstructing relation to said landing head to permit withdrawal of said landing head from said hanger means.
