Coiled tubing is a long, flexible tube made of steel or composite materials that can be wound onto a sizable reel for easy transportation. Coiled tubing operation has become a crucial tool in the oil and gas industry, offering engineers numerous benefits for well interventions and production enhancement.

Engineers in this field must deeply understand coiled tubing to optimize production, improve well performance, and increase efficiency. With its flexible design and various applications, coiled tubing enables engineers to carry out tasks such as well cleaning, selective perforation, and stimulation without costly workovers or well shutdowns.
