Abstract

A hybrid coiled tubing system. The hybrid coiled tubing system may include composite coiled tubing, metallic coiled tubing, and a composite coiled tubing connector coupled to and joining the composite coiled tubing and the metallic coiled tubing.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A hybrid coiled tubing system comprising:
 composite coiled tubing;   metallic coiled tubing; and   a composite coiled tubing connector coupled to and joining the composite coiled tubing and the metallic coiled tubing.   
     
     
         2 . The hybrid coiled tubing system of  claim 1 , wherein a valve is coupled to and positioned between the composite coiled tubing connector and the metallic coiled tubing to control flow between the composite coiled tubing and the metallic coiled tubing. 
     
     
         3 . The hybrid coiled tubing system of  claim 1 , wherein a valve is coupled to and positioned between the composite coiled tubing connector and the composite coiled tubing to control flow between the composite coiled tubing and the metallic coiled tubing. 
     
     
         4 . The hybrid coiled tubing system of  claim 1 , further comprising at least one of piping, composite coiled tubing, or metallic coiled tubing that is joined to the composite coiled tubing via a second connector. 
     
     
         5 . The hybrid coiled tubing system of  claim 1 , further comprising at least one of piping, composite coiled tubing, or metallic coiled tubing that is joined to the metallic coiled tubing via a second connector. 
     
     
         6 . The hybrid coiled tubing system of  claim 5 , wherein the piping is composite piping. 
     
     
         7 . The hybrid coiled tubing system of  claim 5 , wherein the piping is steel piping. 
     
     
         8 . A hybrid coiled tubing system comprising:
 composite coiled tubing;   piping; and   a composite coiled tubing connector coupled to and joining the composite coiled tubing and the piping.   
     
     
         9 . The hybrid coiled tubing system of  claim 8 , wherein a valve is coupled to and positioned between the connector and the composite coiled tubing to control flow between the composite coiled tubing and the piping. 
     
     
         10 . The hybrid coiled tubing system of  claim 8 , wherein a valve is coupled to and positioned between the connector and the piping to control flow between the composite coiled tubing and the piping. 
     
     
         11 . The hybrid coiled tubing system of  claim 8 , wherein the piping comprises composite piping. 
     
     
         12 . The hybrid coiled tubing system of  claim 8 , wherein the piping comprises steel piping. 
     
     
         13 . The hybrid coiled tubing system of  claim 8 , further comprising at least one of piping, composite coiled tubing, or metallic coiled tubing that is joined to the composite coiled tubing via a second connector. 
     
     
         14 . The hybrid coiled tubing system of  claim 8 , further comprising at least one of piping, composite coiled tubing, or metallic coiled tubing that is joined to the piping via a second connector. 
     
     
         15 . A method of performing borehole servicing operations at a job site, the method comprising:
 running a tool string comprising a hybrid coiled tubing system into a borehole, the hybrid coiled tubing system comprising composite coiled tubing, either piping or metallic coiled tubing, and a composite coiled tubing connector coupled to and joining the composite piping and the at least one of the piping and the metallic coiled tubing; and   performing servicing operations within the borehole.   
     
     
         16 . The method of  claim 15 , wherein a valve is coupled to and positioned between the connector and the composite coiled tubing to control flow between the composite coiled tubing and the at least one of the piping and the metallic coiled tubing. 
     
     
         17 . The method of  claim 15 , wherein a valve is coupled to and positioned between the connector and the piping or the metallic coiled tubing to control flow between the composite coiled tubing and the at least one of the piping and the metallic coiled tubing. 
     
     
         18 . The method of  claim 15 , wherein running the tool string comprising the hybrid coiled tubing system into the borehole comprises unspooling the hybrid coiled tubing system from a reel. 
     
     
         19 . The method of  claim 15 , wherein running the tool string comprising the hybrid coiled tubing system into the borehole comprises connecting the composite coiled tubing to the piping or the metallic coiled tubing via a connector to make up the hybrid coiled tubing system at the job site. 
     
     
         20 . The method of  claim 15 , wherein performing the servicing operations within the borehole comprises removing blockages and restrictions from within the borehole.
