Electrical wet-mate connections

Abstract

Electrical cables are attached to an outer surface of production tubing. The electrical cables are configured to be connected at a first end to a topside electrical power supply. Electrical contacts are attached to a second end of the electrical cables. The contacts are at a downhole end of the production tubing.

What is claimed is: 
     
         1 . A wellbore stinger comprising:
 production tubing;   electrical cables attached to an outer surface of the production tubing, the electrical cables configured to be connected at a first end to a topside electrical power supply; and   electrical contacts attached to a second end of the electrical cables, the contacts being at a downhole end of the production tubing.   
     
     
         2 . The wellbore stinger of  claim 1 , wherein the electrical cables are sized to deliver sufficient electrical power to drive an electric submersible pump at full load. 
     
     
         3 . The wellbore stinger of  claim 1 , wherein a downhole end of the production tubing is configured to be received by a polished bore receptacle installed within a wellbore. 
     
     
         4 . The wellbore stinger of  claim 3 , wherein the downhole end of the production tubing comprises a clocking feature configured to align the electrical contacts with corresponding contacts within the polished bore receptacle. 
     
     
         5 . A method comprising:
 receiving an electric submersible pump by a wellbore, the electric submersible pump being secured within the wellbore by a packer;   receiving a polished bore receptacle by the electric submersible pump, the polished bore receptacle comprising electrical contacts within an inner surface of the polished bore receptacle; and   receiving a stinger by the polished bore receptacle, the stinger comprising:
 production tubing; 
 electrical cables attached to an outer surface of the production tubing, the electrical cables configured to be connected at a first end to a topside electrical power supply; and 
 electrical contacts attached to a second end of the electrical cables, the contacts being at a downhole end of the production tubing. 
   
     
     
         6 . The method of  claim 5 , further comprising:
 exchanging electrical power by the electric submersible pump by the electrical cables and contacts; and   producing fluid by the electric submersible pump.   
     
     
         7 . The method of  claim 5 , further comprising:
 releasing, by the polished bore receptacle, the stinger.   
     
     
         8 . The method of  claim 7 , further comprising releasing, by the wellbore, the stinger, the polished bore receptacle, and the electric submersible pump remaining secured within the wellbore. 
     
     
         9 . The method of  claim 8 , wherein the stinger is a first stinger, the method further comprising:
 receiving a second stinger by the polished bore receptacle after releasing the first stinger by the wellbore.   
     
     
         10 . The method of  claim 8 , further comprising servicing the stinger after the stinger is released from the wellbore. 
     
     
         11 . The method of  claim 10 , further comprising:
 receiving the stinger by the polished bore receptacle after releasing the stinger by the polished bore receptacle.   
     
     
         12 . A wellbore system comprising:
 a stinger comprising:
 production tubing; 
 electrical cables attached to an outer surface of the production tubing, the electrical cables configured to be connected at a first end to a topside electrical power supply; and 
 electrical contacts attached to a second end of the electrical cables, the contacts being at a downhole end of the production tubing; 
 a polished bore receptacle configured to receive and retain a downhole end of the stinger; and 
 an electric submersible pump downhole of the polished bore receptacle. 
   
     
     
         13 . The wellbore system of  claim 12 , wherein the electrical cables are sized to deliver sufficient electrical power to drive an electric submersible pump at full load. 
     
     
         14 . The wellbore system of  claim 12 , wherein the polished bore receptacle is uphole of a packer assembly, the packer assembly securing the electric submersible pump within the wellbore. 
     
     
         15 . The wellbore system of  claim 12 , wherein the polished bore receptacle is downhole of a tubing hanger supporting the stinger. 
     
     
         16 . The wellbore system of  claim 12 , wherein the downhole end of the production tubing comprises a clocking feature configured to align with a corresponding feature of the polished bore receptacle, the clocking features configured to align the electrical contacts of the stinger with corresponding electrical contacts of the polished bore receptacle. 
     
     
         17 . The wellbore system of  claim 12 , wherein the electrical cables are a first set of electrical cables, further comprising a second set of electrical cables extending between the electrical contacts within the polished bore receptacle and the electric submersible pump. 
     
     
         18 . The wellbore system of  claim 12 , wherein casing within the wellbore is seven inch casing or greater.
