How SWTorpedo well stimulation is different from Common Explosives and Propellant Tools?
SWTorpedo Tool is conceptually different from Propellant Tools and technologically different from Common Explosives. All of Propellant Tools use the burning process (deflagration) of solid propellants or gun powders to generate gas. Usually build-up pressure is enough to create no more than 2 of two directional vertical fractures. Gas will be forced through the perforations in to formation. As propagation of initial fractures progress gas will be consumed faster than propellant can generate it, as a result no new fractures can be created. This process explained by the law of A. Griffith. Common Explosives when used generate powerful impulse or wave which causes rock crashing. Its differential stress will reach a point when it is higher than effective normal stress and main fracturing force is a force of compression. Very often Common Explosives reduce permeability near the wellbore. SWTorpedo Tool use smaller charges of high explosives. Multiple charges are detonated in such succession
