Cable Hanger with Integrated Internal Tree Cap

Abstract

A cable hanger for use in a tree of a well including a bore includes a body and first and second barrier systems located on the body. The first barrier system includes a first seal configured to seal against the bore of the tree to establish a pressure barrier, and a first latching mechanism, wherein upon actuation, is configured to engage the tree and hold the cable hanger in place in the tree. The second barrier system includes a second seal configured to seal against the bore of the tree, and a second latching mechanism, configured such that upon actuation, it engages the tree and holds the cable hanger in place in the tree. The cable hanger further includes at least one of a hydraulic line or an electrical conductor extending through a portion of the body.

What is claimed is: 
     
         1 . A cable hanger for use in a tree of a well including a bore, comprising:
 a body;   a first barrier system located on the body, comprising
 a first seal configured to seal against the bore of the tree to establish a pressure barrier; and 
 a first latching mechanism, configured such that upon actuation, it engages the tree and holds the cable hanger in place in the tree; 
   a second barrier system located on the body, comprising:
 a second seal configured to seal against the bore of the tree; and 
 a second latching mechanism, configured such that upon actuation, it engages the tree and holds the cable hanger in place in the tree; and 
   at least one of a hydraulic line or an electrical conductor extending through a portion of the body.   
     
     
         2 . The cable hanger of  claim 1 , wherein the first and second latching mechanisms are actuatable during a single running trip, and wherein the first barrier system is testable during the running trip. 
     
     
         3 . The cable hanger of  claim 1 , further comprising a hydraulic coupler located on the body, the hydraulic coupler configured to provide external access to the hydraulic line. 
     
     
         4 . The cable hanger of  claim 1 , wherein the hydraulic coupler is moveable between a closed position and an open position in which external access to the hydraulic line is established. 
     
     
         5 . The cable hanger of  claim 1 , further comprising an alignment feature configured such that the cable hanger is alignable relative to the tree as the cable hanger is landed. 
     
     
         6 . The cable hanger of  claim 5 , further comprising a hydraulic coupler configured to provide external access to the hydraulic line, and wherein the hydraulic coupler is aligned with a hydraulic connector bonnet when oriented relative to the tree. 
     
     
         7 . The cable hanger of  claim 1 , further comprising a wet-mate connector coupled to the electrical conductor, hydraulic line, or both. 
     
     
         8 . A well completion, comprising:
 a tree; and   a cable hanger located within the production tree, the cable hanger comprising:
 a body; 
 a first barrier system located on the body, comprising
 a first seal configured to seal against the tree to establish a first pressure barrier; and 
 a first latching mechanism, configured such that upon actuation, it engages the tree and holds the cable hanger in place in the tree; 
 
 a second barrier system located on the body, comprising:
 a second seal configured to seal against the tree to establish a second pressure barrier; and 
 a second latching mechanism, configured such that upon actuation, it engages the tree and holds the cable hanger in place in the tree; and 
 
 at least one of a hydraulic line or an electrical conductor extending through a portion of the body. 
   
     
     
         9 . The cable hanger of  claim 8 , wherein the first and second latching mechanisms are actuatable during a single running trip, and wherein the first barrier system is testable during the running trip. 
     
     
         10 . The well completion of  claim 8 , wherein the cable hanger comprises a hydraulic coupler aligned with a hydraulic connector bonnet of the tree, and wherein the hydraulic coupler is coupled to the hydraulic line of the cable hanger. 
     
     
         11 . The well completion of  claim 10 , wherein the hydraulic connector bonnet couples the hydraulic line of the cable hanger with a hydraulic source. 
     
     
         12 . The well completion of  claim 8 , further comprising a downhole tool suspended from the cable hanger. 
     
     
         13 . The well completion of  claim 12 , wherein the downhole tool is an ESP and the tree is a subsea production tree. 
     
     
         14 . The well completion of  claim 8 , wherein at least one of the tree and the cable hanger comprises an alignment feature configured to position the cable hanger with respect to the tree during landing of the cable hanger. 
     
     
         15 . A method of deploying a tool downhole in a well, comprising:
 lowering the tool downhole, wherein the tool is suspended from a cable hanger;   landing the cable hanger within a tree, wherein the cable hanger comprises a first actuatable barrier system and a second actuatable barrier system configured to establish dual pressure barriers and hold the cable hanger within the tree;   actuating the first barrier system;   actuating the second barrier system; and   wherein lowering the tool, landing the cable hanger, actuating the first barrier system, and actuating the second barrier system are performed during a single running trip.   
     
     
         16 . The method of  claim 15 , further comprising testing the first barrier system during the single running trip and before actuation of the second barrier system. 
     
     
         17 . The method of  claim 15 , further comprising delivering power, communications, hydraulics, or any combination thereof, to the tool through the cable hanger. 
     
     
         18 . The method of  claim 15 , further comprising aligning a hydraulic coupler of the cable hanger with a hydraulic connector bonnet of the tree. 
     
     
         19 . The method of  claim 18 , further comprising accessing the hydraulic line of the cable hanger via the hydraulic connector bonnet. 
     
     
         20 . The method of  claim 15 , wherein the tool comprises an electrical submersible pump (ESP) and the tree is a subsea production tree
