Abstract: A cutting assembly for external conduits on a tubing string or main tubular conduit features at least one breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing that is integral with a passage having threaded end connections. While in some scenarios it is preferred that the main tubular conduit is severed below the cutting assembly thus allowing the cutting apparatus to be retrieved with the upper portions of the cut main tubular conduit and external longitudinal member(s), in other circumstances it may be desired that the main tubular conduit is severed above the cutting assembly allowing the cutting apparatus to be left “downhole” with the lower portion of the cut main tubular conduit and the BHA. The cutter knife assembly chambers or channels can be in banks that are axially spaced using bypass channels to access lower banks.

Abstract: A cutting assembly for external conduits on a tubing string features a breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing. Upon severing of the string and applying a pickup force, a tension is applied to each external conduit since the severing of the string happens above all the cutter housings. Each housing cuts at least one conduit and the upper portion of the string brings with it the upper portion of the external conduit while the lower portions of each cut external conduit are retained in the cutter housings that remain downhole below the breakaway. In that manner there are no loose external conduit ends to interfere with and/or disturb subsequent fishing or other wellbore operations.
