Overview

DescriptionNT Super Tubing Cutters are designed for use in Pipe Recovery Operations as a finalsolution. The cutter is undersized to get through tight restrictions where a conventionalcutter is not an option.

Operation

NT Super Tubing Cutters provide a quick and effective solutions to sever tubing. NTSuper Tubing Cutters utilize unique manufacturing and packaging processes to alloweasy shipment and fast delivery to the customer.

NT Super Tubing Cutters should be used when restrictions prohibit the use ofconventional tubing cutters. The cutter with the largest possible diameter capable ofrunning in the well should be chosen to achieve maximum performance. A gauge run isrecommended prior to running the tool to insure the cutter can get to proper depth. Thiswill prevent any safety concerns like sticking a live cutter in the well or spudding withexplosive tools. NT Super Tubing Cutters are to be shot in the tubing above the stuckpoint, but not at the collar. To maintain the maximum allowable performance from thecutter, it should be centralized. A de-centralized cutter may result in a partial cut and/ordamage to the casing. It is also recommended that tension be applied to the tubing priorto detonation of the Tubing Cutter to assist in the removal of stuck tubulars.

NT Super Cutters utilize explosive technology and are designed to explosively severtubular members when initiated by an Owen's Resistorized Bridge Detonator. Owen'selectrical detonators adhere to API RP-67 specifications. All safety rules and regulationsshould be strictly followed when storing, handling, assembling, and using these cuttersand/or detonators. Safety precautions should be taken in accordance with yourcompany's safety policies, governmental regulations, and the American PetroleumInstitute Recommended Practice 67 (API RP-67).

NT Super Tubing Cutters come standard with HMX explosive powder rated to 400 F(204C ) for 1 hour. Cutters are also available with HNS [500F (260C) - 1 hour] by

special order.
