Coiled tubing for oil industry

The development of coiled tubing as we know it today dates back to the early 1960s, and it has become an integral component of many good services and workover applications.

Physically, coiled tubing appears in drilling sites as a long metal pipe rolled over a huge reel. The pipe is usually made of steel or special composites that give it adequate flexibility to be wound around the reel without fracture.

Coiled tubing is a long metal pipe that is surrounded or rolled over a large reel that is brought to the well site when any well repair or workover activities are to be performed. There are no joints in between the coiled tube which means that it’s a continuous long metal pipe that can be taken inside the borehole to the depth of up to 15000 feet.

Coiled tubing helps in improving the well & reservoir performance. There is a wide range of operations on the site that makes use of coiled tubing such as:

-Milling

-Drilling

-Rock fracturing

-Sidetracking

-Production tubing

-Low bottom hole pressure drilling

-Wellbore cleanout

-Nitrogen kickoff

-Sand control

-Cementing

-Mechanical isolation

-Tube Logging & perforating

Actually, while well service/workover applications still account for more than 75% of CT use, technical advancements have increased the utilization of CT in both drilling and completion applications.
