Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 22–25, 2021
Paper Number: SPE-204410-MS
... Coiled tubing units (CTUs) and snubbing units have been used for decades in onshore and offshore applications. Both provide a means to safely enter and exit a pressurized well in a controlled manner. Coiled tubing consists of a continuous spool of malleable pipe with typical sizes of 2", 2 3/8...
