Coiled Tubing Lockup is a condition in which no coiled tubing forces or movement can be transmitted downhole. Explanation:One benefit of coiled tubing over slickline or wireline is that it could be easily run in deviated or horizonal wells.However, in some situations even with coiled tubing we are unable to reach the targeted depth.From the […]

While selecting or assigning a coiled tubing string to perform a job on a particular well, coiled tubing engineer makes sure that the CT sring can meet: Withstand the maximum tensile load, when it is at the bottom of well. In addition it must be able to withstand a certain over pull in case BHA […]

Many bridge plugs can be run on drillpipe, CT, or wireline. A hydraulic settingtool is used for setting a bridge plug using CT, while a wireline setting tool isused for wireline applications.Most hydraulic setting tools set the packer by dropping a ball and pressuringup the CT string. CT Wired ApplicationsCT wired applications refers to those […]

Injector Head is one of the six major components of coiled tubing unit, used to run or pull and hold the CT string into the wellbore. Major parts of injector headchain system, drive and brake system, chain tension system, chain traction system, weight measurement system. The CT unit is identified by the rating of injector […]
