Coiled Tubing is the process of running a reel of continuous tubing into a well that is still under pressure. Coiled Tubing equipment is portable and modular although modern reels are reaching high transport weights and offers quick rig-up times.
The maximum working depth of Coiled Tubing is usually determined by the amount of tubing that can be spoiled onto a reel rather than the TVD. Highly deviated wells can cause problems with Coiled Tubing as, like wireline, gravity is required to keep the tubing moving down the well-bore. This can now be overcome to a certain extent with the use of downhole “tractors” which pull the coiled tubing from the bottom. Coiled Tubing can be used for a very wide range of jobs such as, Nitrogen lifting wells, Clean-up operations, Spotting acid at the perforations, fishing operations, Spotting cement and PLT.
