摘要： The present invention provides an explosive method that improves on methods currently employed. The present invention provides for a safer, less expensive, and more portable explosive device. The elements of the present invention replace dynamite or similar explosives currently used in avalanche control and bore hole blasting of rock or other solids. The present invention comprises an apparatus and a method providing a much safer alternative employing a highly confined combustion reaction of a flammable vapor, whereas dynamite is a category 1.1 high explosive imbued with all the attendant safety and security concerns. The method of the present invention provides for an improved and safer method of blasting employing a highly confined combustion reaction of a flammable vapor instead of conventional explosives currently used.

摘要： An explosive system for fracturing an underground geologic formation adjacent to a wellbore can comprise a plurality of explosive units comprising an explosive material contained within the casing, and detonation control modules electrically coupled to the plurality of explosive units and configured to cause a power pulse to be transmitted to at least one detonator of at least one of the plurality of explosive units for detonation of the explosive material. The explosive units are configured to be positioned within a wellbore in spaced apart positions relative to one another along a string with the detonation control modules positioned adjacent to the plurality of explosive units in the wellbore, such that the axial positions of the explosive units relative to the wellbore are at least partially based on geologic properties of the geologic formation adjacent the wellbore.

摘要： What is presented is a high power igniter that releasably secures to a cutting apparatus that is used for radially projecting a flow of heated gas to cut from an internal surface through an external surface of a conduit used for oil, gas, mining, and underwater pressure sealed tool applications. The high power igniter comprises an igniter housing adapted to be positioned in the conduit. The igniter housing comprises a containment sub and a nozzle sub that releasably secure to each other. The nozzle sub for directing the flow of the heated gas toward the cutting apparatus and releasably securing to the cutting apparatus. A high wattage heater in the igniter housing comprises a metal magnalium thermite pellet insertable into the igniter housing for creating the flow of heated gas when the high power igniter is in use and a pellet igniting device.

摘要： 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.

摘要： A method and system for destroying information stored on a data storage device located onboard a vehicle in order to prevent unfriendly forces from obtaining the information is described. The method and system are initiated when the operator of the vehicle activates a triggering mechanism. The information may be destroyed by physically damaging the data storage device on which the information is stored or by releasing a software virus into the device on which the sensitive information is stored. A software virus may also be transmitted to a computer of an unfriendly force attempting to access the sensitive information.
