Producing wells become deficient because of mechanical problems within the well or depletion of the oil or gas reservoir. Workover is an operation within the well's bore to repair equipment malfunction or well situation, or to enhance the well's performance. Workover performed through existing tubing by means of smaller diameter tubing is called thru-tubing workover. Snubbing utilizes jointed tubing or drill pipe and a hydraulic snubbing unit to run tubing or pipe under pressure conditions without killing the well. Tubing is run either through the blowout preventers and bore of an uncompleted well or through the well-head and tubing of a completed well. Hydraulic snubbing units offer many advantages to well productivity. Some of these are discussed in this article.
