Abstract
Stuck pipe is a common problem with tremendous impact on drilling efficiency and costs in the oil industry. Generally, the stuck pipe troubles are solved after their occurrences by using some standard operational procedures such as working the drill string up or down, attempting to rotate the string and pumping mud at higher flow rates through the drill bit to aid pipe release. One may also place different fluids around the stick area and use a drilling jar. However, in cases where common solutions don't work, then the cutoff is the last resort. To have a successful cutoff operation, estimating the location of the free point and choosing the right cutting tool is of vital importance. This paper presents the Radial Cutting Torch (RCT) as a innovative cutting tool and its oilfield application in stuck pipe events.

The Radial Cutting Torch (RCT) tool provides the industry in a safe, efficient and reliable way used as an alternative to explosives and perilous chemicals to cut different types of stuck pipe
Summary
Leković B.; Šumar N.; Karović-Maričić V.; Danilović D. It is not unusual for a drill string to get stuck against the uncased borehole wall by lodged in their irregularities, demanding crew experience, ability and rig power to release it If all of this doesn't help, the only appropriate solution is to sever and discard the stuck part and again attempt to hit the target zone by sidetracking; which includes fundamental changes in the drilling program. A correct approach is to establish the partnership between operators and service companies in order to significantly pare down hazards, operational stagnation and overall expenses This is made by providing frequent drills for drilling personal which means emboldening the suitable and timely usage of Radial Cutting Torch (RCT) device that have become a new component of contingency plans (Raja and Dodds, 2011)
