Coiled Tubing 1
Coiled Tubing 1 : (1) (adj.) Drilling. A long, continuous length of pipe wound on a spool. The pipe is straightened prior to pushing into a wellbore and rewound to coil the pipe back onto the transport and storage spool. Depending on the pipe diameter (1 in. to 4 1/2 in.) and the spool size, coiled tubing can range from 2, 000 ft to 15, 000 ft [610 to 4, 570 m] or greater length. Syn: Endless Tubing, Reeled Tubing. Alt. form: CT. See: coiled tubing drilling, packer. More Details: Coiled Tubing Takes Center Stage; Coiled Tubing: Innovative Rigless Interventions. (2) (adj.) Well Workover and Intervention. A generic term relating to the use of a coiled tubing string and associated equipment. As a well-intervention method, coiled tubing techniques offer several key benefits over alternative well-intervention technologies. The ability to work safely under live well conditions, with a continuous string, enables fluids to be pumped at any time regardless of the position or direction of travel. This is a significant advantage in many applications. Installing an electrical conductor or hydraulic conduit further enhances the capability of a coiled tubing string and enables relatively complex intervention techniques to be applied safely.
