... without making connections. The length of CT depends on the length of the lateral or the distance from the first to the last section being treated. This ensures that the string can be moved freely without making a connection. Fig. 1 shows the setup of a hybrid unit on location, including a reel trailer...

... to accessing deeper reserves, the coiled tubing (CT) work strings required for intervention operations have become longer and heavier. By far, the largest and heaviest component of a CT unit is the coiled tubing itself and the reel on which it is handled. Often, due to the weight of a CT reel and the inability...
