Abstract
A method of severing a tubing string of a well system comprising: positioning a jet cutter within the tubing string, wherein the jet cutter comprises: (A) a main explosive load, wherein upon detonation or deflagration of the main explosive load, a jet propagates radially outward in a circle from an apex of the main explosive load; and (B) a liner, wherein the liner is truncated at the apex, and wherein the amount of truncation is selected such that the jet has a greater tip velocity compared to a substantially identical jet cutter without the truncated liner; and causing the main explosive load to detonate or deflagrate, wherein the tubing string of the well system is severed due to the detonation or deflagration.
