In the oil and gas industry, coiled tubing refers to metal piping, normally 1" to 3.25" in diameter, used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells, however coil tubing can perform almost any operation for oil well operations if used correctly.
Coiled Tubing comes spooled on a large reel and is often used to carry out operations similar to wirelining. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole rather than relying on gravity.
A Coiled Tubing operation is normally performed through the drilling derrick on the oil platform, which is used to support the surface equipment, although on platforms with no drilling facilities a self-supporting tower can be used instead. It can also be run using smaller service rigs, and for light operations a mobile self-contained coiled tubing rig can be used.
Coil tubing has also been used as a less costly version of work-over operations. It is used to perform open hole drilling and milling operations. It can also be used to fracture the reservoir.
