ABSTRACT:
A cutting tool to cut a tubular element in a well is constructed of pellets of less sensitive explosive material detonated by a pellet of a more sensitive explosive material. All the explosive material is packaged in individual packages which qualify for a lower cost, faster, safer transportation classification, but which explosive material is consolidated and assembled at a field location into a cutting tool capable of generating a sufficient force to cut the tubular element. A corresponding method is also disclosed.
