In the oil and gas industry, coiled tubing refers to a long metal pipe, normally 1 to 3.25 in (25 to 83 mm) in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining ...

May 31, 2022 · Coiled tubing is used in long, horizontal wells, or instead of cable if drilling or completion fluid is to be circulated in the well. Coiled tubing can be used for both well workover and well drilling.

Coiled tubing (CT) refers to a continuous length of small-diameter steel pipe and related surface equipment as well as associated drilling, completion and workover, or remediation, techniques. Coiled tubing oilfield technology was initially developed for working on live, producing wells.

Nov 14, 2020 · Coiled tubing is a metal pipe used to perform various well completion, drilling, and intervention operations. This metal pipe is flexible enough to be stored on the reel. Coiled tubing string comes in various sizes ranging from 1” to almost 4” in diameter in some cases.

Aug 21, 2024 · This article describes the operation and applications for coiled tubing units (CTUs), and it specifically covers the well control stack and industry recommended practices for pressure testing coiled tubing.

In the oil and gas sector, coiled tubing operation is a technique used for well intervention without using traditional drill pipes. It employs a continuous coil of tubing, typically made of steel or composite material, wound onto a large spool and then inserted into the wellbore.

Real-time coiled tubing services combine intervention and diagnostics to monitor and optimize job performance. Halliburton is committed to providing superior technology and cutting-edge research with the best customer service in the coiled tubing industry.

Coiled Tubing (CT) has been defined as any continuously-milled tubular product manufactured in lengths that require spooling onto a take-up reel, during the primary milling or manufacturing process. The tube is nominally straightened prior to being inserted into the wellbore and is recoiled for spooling back onto the reel.

SLB has an optimal portfolio of services and technologies to perform efficient and effective coiled tubing (CT) interventions. Applications include matrix and fracture stimulation, wellbore cleanout, logging, perforating, nitrogen kickoff, sand control, drilling, cementing, well circulation, and mechanical isolation.
