Spooled device guide system

Abstract

A technique facilitates coiled tubing operations in offshore environments. The technique employs a spooled device, which is disposed on a reel located on an offshore facility. A guide system is mounted on the offshore facility to guide the spooled device from the reel, along a desired path, and down through the floor of the offshore facility. The guide system enables the coiled tubing job to be conducted without requiring a line of sight along the coiled tubing as it is delivered down through the offshore facility.

1 . A system for deploying coiled tubing, comprising:
 an offshore rig having an upper deck, a lower deck, and a derrick extending upwardly from the upper deck;   a coiled tubing reel mounted on the lower deck; and   a coiled tubing guide positioned to route coiled tubing from the coiled tubing reel, past the upper deck, up along the derrick, and back down through a lower end of the derrick.   
     
     
         2 . The system as recited in  claim 1 , wherein the coiled tubing guide comprises a pipe. 
     
     
         3 . The system as recited in  claim 1 , wherein the coiled tubing guide is permanently installed on the offshore rig. 
     
     
         4 . The system as recited in  claim 1 , wherein the coiled tubing guide is continuous from the coiled tubing reel to the lower end of the derrick. 
     
     
         5 . The system as recited in  claim 1 , wherein the coiled tubing guide is intermittent from the coiled tubing reel to the lower end of the derrick. 
     
     
         6 . The system as recited in  claim 1 , wherein the coiled tubing guide is adjustable in length. 
     
     
         7 . The system as recited in  claim 1 , wherein the coiled tubing guide comprises a swivel. 
     
     
         8 . The system as recited in  claim 1 , wherein the coiled tubing guide comprises a trumpet end to reduce stress on coiled tubing moving through the coiled tubing guide. 
     
     
         9 . The system as recited in  claim 1 , wherein the coiled tubing guide is lubricated with a fluid. 
     
     
         10 . A system for guiding, comprising:
 a spooled device disposed on a reel located on an offshore facility;   a wellhead for receiving the spooled device; and   a tubular guide system positioned between the reel and the wellhead to enable use of the spooled device without requiring a line of sight control of the spooled device as it is delivered through the offshore facility to the wellhead.   
     
     
         11 . The system as recited in  claim 10 , wherein the offshore facility comprises an offshore rig platform installation. 
     
     
         12 . The system as recited in  claim 10 , wherein the offshore facility comprises a semi-submersible rig. 
     
     
         13 . The system as recited in  claim 10 , were in the offshore facility comprises a monohull vessel. 
     
     
         14 . The system as recited in  claim 10 , wherein the spooled device comprises coiled tubing. 
     
     
         15 . The system as recited in  claim 10 , wherein the tubular guide system comprises a steel pipe through which the spooled device moves. 
     
     
         16 . The system as recited in  claim 10 , wherein the tubular guide system comprises a continuous pipe from the reel to the wellhead. 
     
     
         17 . The system as recited in  claim 10 , wherein the tubular guide system is routed to a blowout preventer impact deck. 
     
     
         18 . A method, comprising:
 locating a reel with a spooled device on an offshore facility;   mounting a guide system on the offshore facility to guide the spooled device; and   orienting the guide system to deliver the spooled device through an opening in a floor of the offshore facility without requiring a line of sight along the spooled device when it is moved through the opening in the floor.   
     
     
         19 . The method as recited in  claim 18 , further comprising unspooling the spooled device from the reel and guiding the spooled device via the guide system. 
     
     
         20 . The method as recited in  claim 18 , wherein locating comprises locating the reel on a lower deck of an offshore platform. 
     
     
         21 . The method as recited in  claim 18 , wherein mounting comprises permanently mounting an enclosed guide system onto an offshore platform. 
     
     
         22 . The method as recited in  claim 18 , wherein locating comprises locating a coiled tubing reel. 
     
     
         23 . The method as recited in  claim 18 , wherein mounting comprises mounting a tubing up along a side of a derrick and down through a central, lower end of the derrick. 
     
     
         24 . The method as recited in  claim 18 , wherein orienting comprises pivoting a portion of the guide system to a desired position.
