Abstract
It is sometimes necessary to sever a downhole tubular structure in the course of conducting subterranean operations. Detonation of an explosive material may be used to sever a tubular structure in some instances. Downhole severing tools may comprise: a housing; a two-stage energizing material within the housing, the two-stage energizing material comprising a high explosive and a reactive energizing material; at least one initiator coupled to the two-stage energizing material at least at a first location; and a detonator coupled to the at least one initiator; wherein upon detonation of the two-stage energizing material, the high explosive undergoes a primary reaction that propagates a secondary reaction of the reactive energizing material.
