Abstract
A method of severing at least a first object comprises: positioning a severing device adjacent to the first object, wherein the first object is a wireline or a tubular, and wherein the severing device comprises: a first reactant, and a second reactant; initiating a reaction, or allowing a reaction to occur, between the first reactant and the second reactant, wherein the reaction is an exothermic reaction, and wherein heat evolved from the reaction has a temperature greater than or equal to the melting point of the first object; and directing at least a portion of the heat from the outside of the first object through the first object.
