Definition - What does Coiled-Tubing Workover mean?
Coiled-Tubing Workover is a type of oil well intervention technique used as a competitive form of workover operations. This technique involves the use of coiled tubing. It can be used to perform milling and drilling operations, and also to crack the reservoir. It is a process in which a fluid is pressurized to a thousand psi at a definite point in the well to break rocks apart and allow the flow of products. If used in a proper way, the coiled tubing can perform any operation in the oil well.
Petropedia explains Coiled-Tubing Workover
Coiled tubing is a long metal pipe that is supplied spooled on large reels. Workover is any type of oil well intervention operation that involves various invasive techniques such as snubbing or coiled tubing. Coiled tubing is usually used to perform various operations identical to wirelining. Before workover operations, the well is required to be killed. The intensive nature of workover operations is not at all less than the abilities of drilling rigs. Coiled-Tubing Workover is a cheaper form of workover activities used to perform various milling and drilling activities.
