System and Method for Conveying a Wired Coiled Assembly

Abstract

A coiled tubing connection system is used in a well. A connector having an engagement end is used to couple a wellbore device to the end of a coiled tubing. The connector is spoolable, and the engagement end comprises engagement features that facilitate formation of a connection that is dependable and less susceptible to separation.

1 . A method of performing a wellbore operation comprising:
 providing a coiled tubing;   attaching a coiled tubing connector to the coiled tubing;   attaching a cable termination head to the coiled tubing connector;   running a cable through each of the coiled tubing, the coiled tubing connector and the cable termination head to form a wired coiled tubing assembly;   terminating the cable at the cable termination head; and   running the wired coiled tubing assembly through a coiled tubing injector.   
   
   
       2 . The method of  claim 1 , wherein the cable is terminated at the cable termination head prior to running the wired coiled tubing assembly through the coiled tubing injector. 
   
   
       3 . The method of  claim 1 , wherein the wired coiled tubing assembly forms a substantially continuous outer diameter. 
   
   
       4 . The method of  claim 1 , wherein exposed outer diameter portions of the coiled tubing, the coiled tubing connector and the cable termination head are all substantially equal. 
   
   
       5 . The method of  claim 1 , wherein exposed outer diameter portions of the coiled tubing, the coiled tubing connector and the cable termination head are each sized to be within a tolerance of the coiled tubing injector. 
   
   
       6 . The method of  claim 1 , wherein the cable comprises one or more electrical conductors, and wherein said terminating comprises forming an electrical connection between each electrical conductor and a corresponding electrical ending of the cable termination head. 
   
   
       7 . The method of  claim 6 , wherein the electrical ending is chosen from the group consisting of a pin connection and a socket connection. 
   
   
       8 . The method of  claim 1 , wherein the cable comprises one or more optical lines. 
   
   
       9 . A method of performing a wellbore operation comprising:
 providing a coiled tubing injector;   providing a coiled tubing;   attaching a coiled tubing connector to the coiled tubing;   attaching a cable termination head to the coiled tubing connector;   running a cable through each of the coiled tubing, the coiled tubing connector and the cable termination head to form a wired coiled tubing assembly;   terminating the cable at the cable termination head;   running the wired coiled tubing assembly through the coiled tubing injector;   attaching a well tool to the wired coiled tubing assembly;   conveying the well tool to a desired depth within a wellbore; and   operating the well tool to perform the wellbore operation.   
   
   
       10 . The method of  claim 9 , wherein the cable is terminated at the cable termination head prior to running the wired coiled tubing assembly through the coiled tubing injector. 
   
   
       11 . The method of  claim 9 , wherein the wired coiled tubing assembly forms a substantially continuous outer diameter. 
   
   
       12 . The method of  claim 9 , wherein exposed outer diameter portions of the coiled tubing, the coiled tubing connector and the cable termination head are all substantially equal. 
   
   
       13 . The method of  claim 9 , wherein exposed outer diameter portions of the coiled tubing, the coiled tubing connector and the cable termination head are each sized to be within a tolerance of the coiled tubing injector. 
   
   
       14 . The method of  claim 9 , wherein the cable comprises one or more electrical conductors, and wherein said terminating comprises forming an electrical connection between each electrical conductor and a corresponding electrical ending of the cable termination head. 
   
   
       15 . The method of  claim 14 , wherein the electrical ending is chosen from the group consisting of a pin connection and a socket connection. 
   
   
       16 . The method of  claim 14 , wherein said attaching comprises forming an electric connection between the well tool and the wired coiled tubing assembly by a plug in type connection to allow for one of power transmission and data transmission between the well tool and equipment at a surface of the wellbore. 
   
   
       17 . The method of  claim 9 , wherein said attaching comprises forming one of an electric connection and an optical connection between the well tool and the wired coiled tubing assembly by a plug in type connection. 
   
   
       18 . The method of  claim 9 , wherein said attaching comprises forming an optical connection between the well tool and the wired coiled tubing assembly by a plug in type connection to form an optical pathway between the well tool and equipment at a surface of the well for transmission of data therebetween.
