The coiled tubing (CT) resurgence, which began in late 1989 shows little sign of moderating in spite of lower oil and gas prices. In fact, this so-called revolution continues to expand into major new services and applications. CT units are replacing workover rigs and snubbing units in some areas and have recently started to replace drilling rigs even outside Alaska's North Slope Prudhoe Bay field. Activity is reaching record levels in many areas. Although drilling, completions and flowlines generate a lot of interest, these are currently only a small part of total CT business. About 75% of activity is split evenly between nitrogen, acidizing and cleanouts. The other 25% includes newer services like cementing, fishing, sliding sleeves, logging, underreaming to remove scale or cement and drilling. CT is used to drill slimholes and reentry drainholes up to 6 1/8-in. CT has been used as casing and more casing applications are planned. CT ODs to 3 1/2-in. are produced and 4 1/2-in. OD CT production is scheduled later this year. Larger ODs make CT feasible for replacing conventional jointed tubing and welded flowlines.
