We developed the Dual End Severing Tool for severing thick wall tubulars in the 1980’s. The technique is based on the Colliding Shock Wave Principle. Since its inception, the Drill Collar Severing Tool has been continuously refined, resulting in the industry-leading severance device for cutting drill collars and drill pipe in a wide variety of stuck pipe scenarios. This tool is useful when restrictions preclude the use of conventional drill pipe and casing cutters. The secret to the success of the tool lies in the precisely-timed detonation of two equal and opposing shock fronts. The colliding shock is matched to a cartridge assembly at the mid-point of the assembly, designed to help focus the energy transmitted to the target. JRC developed the industry standard shock attenuating mandrel for use with Drill Collar Severing Tools and patented this technology (US patent 5,117,911). Drill Collar Severing Tools can be used with JRC’s Proprietary Rig Environment Detonator - RED- offering a high level of protection against stray voltage or inadvertent RF-initiation.
