3. prepare end of coiled tubing (cut and straighten as required). make up, pull test and pressure test coiled tubing connector 4. pump largest possible ball (and/or cleaning pig) through reel to remove pipe scale and ensure no obstruction 5. make up rest of bha. only use wrenches on heavy wall areas on tool bodies 6. make-up and pressure test. This comprehensive, page book covers the spectrum of coiled-tubing operations and is written for both technical and non-technical readers. “Coiled Tubing Operations” provides a general description of coiled tubing units (CTU), as well as CTU components, . Coiled Tubing Well The global oil and gas industry is using coiled tubing for an ever-increasing array of well intervention projects. Coiled tubing offers a number of operational and economic advantages, including: live well intervention, elimination of well kill and potentially damaging heavy-weight kill fl .

Coiled Tubing Units Overview. Halliburton Coiled Tubing Units (CTU's) are named according to the pulling load rating (in klbs) of the Injector head. These are made in a range of different sizes to suit different applications. Standard Units versus DNV Certified Units. Most new units are available as a standard option or as a DNV (Det Norske. 4 NOV is the largest independent downhole tool and equipment provider in the world. We have the expertise to optimize your bottomhole assembly. Coiled tubing, referred to a continuous long metal pipe spooled on a large reel, is widely used for intervention in oil and gas wells. It can easily be pushed in and out during the operation while drill pipes must be assembled by joints. Coiled tubing drilling, shorted for CTD, is a relatively modern drilling technique, using coiled tubing.

This Coiled-Tubing Drilling (CTD) Sound Practices Manual provides tools needed by CTD engineers and supervisors to plan, design and perform safe, successful CTD operations. As emphasized throughout, both careful planning and attention to detail are mandatory for success. Coiled Tubing Units Overview.
