The Weatherford drill pipe severing tool is a JRC-supplied dual-end severing
device for cutting thick-wall tubulars. The cutting technique is based on the colliding
shock wave principle. Since its inception more than 20 years ago, the JRC tool has
been continuously refined, resulting in the industry's leading severance device for
cutting drill collars and drill pipe in a wide variety of stuck pipe scenarios.
The tool's latest refinement has resulted in a standard explosive column length with
superior performance. The tool success lies in the precisely timed detonation of two
equal and opposing shock fronts. The colliding shock, designed to help focus the
energy transmitted to the target, is matched to a cartridge assembly at the mid
point of the assembly.
