| Summary: | Coiled tubing has been continuously used successfully around the world. Various of companies has proven its advantage during drilling operation which cause this advance drilling technology a very important part specially on drilling underbalance well, workover, slimhole drilling and re-entry wells. Drilling with coiled tubing saves time and cost of operation thus increases profit. Selection of which how long coil tubing string shall be used in drilling varies with depth of the reservoir. However, in the life of coiled tubing string a residual bend exist. Initially coiled tubing is not straight tubing when placed inside a wellbore as it has a certain residual bend which is bound to happen. This paper’s aim is to explain how this residual bend that is present in coiled tubing affect on string maximum length before lock-up occurs on tubing. |
