Abstract: A method and system for downhole operations that includes an energetic material with a reduced sensitivity to temperature, and a temperature rating that is higher than other energetic materials. Downhole tools that use energetic material thus can have a higher temperature rating with the reduced sensitivity energetic material. One embodiment of the energetic material includes an energetic heterocycle compound, such as 2,6-diamino-3,5-dinitropyrazine-1-oxide.

Abstract: An igniter initiates combustion in an amount of explosive that is downhole and adjacent the igniter. The igniter includes an amount of combustible material and a resistive igniter element disposed on a side of the combustible material that faces the amount of explosive. Applying a designated amount of electricity to the resistive igniter element generates sufficient heat to ignite the combustible material. Strategically initiating ignition adjacent the amount of explosive generates a flame front that travels away from the explosive, which in turn directs a flame against the explosive substantially the entire time the combustible material burns.

Abstract: A shaped charge for use in perforating a wellbore that includes a shaped charge case, a liner in the case, and explosive between the liner and case. Detonating the explosive inverts the liner to form a metal jet that forms a perforation in a side wall of the wellbore. The outer diameter of the liner open end is set radially inward from the inner diameter of the case opening to define an annular gap. Providing a gap between the liner and case allows more control of distribution of material of the liner into the jet.

Abstract: A shaped charge having a charge case and liner with an outer layer and an inner layer. The liner is a generally hollow frustoconically shaped member with an open end and a closed end, where the closed end of the liner inserts into an opening in the charge case. An explosive is provided between the liner and the charge case. The inner layer of the liner includes a higher density material than material used for forming the outer layer.

Abstract: A shaped charge having a liner, a shaped charge case, high explosive between the ilner and the case, and an active wave shaping element that is made of an energetic material that reacts at a rate different from the high explosive. The wave shaping element is disposed in the high explosive between an apex of the liner and base of the shaped charge case. Example materials of the wave shaping element include HMX, RDX, PBX types, PETN, HNS, TATB, and combinations thereof.

Abstract: A shaped charge liner formed by injection molding, where the liner comprises a powdered metal mixture of a first and second metal. The mixture includes about 50% to about 99% by weight percent of the first metal, about 1% to about 50% by weight percent of a second metal, about 1% to about 50% by weight percent of a third metal. In one embodiment, the first metal comprises tungsten, the second metal may comprise nickel, and the third metal may comprise copper.

Abstract: A liner for a shaped charge formed from a mixture of powdered heavy metal and a powdered metal binder. The liner is formed by compression of the mixture into a liner body. In one embodiment of the invention, the mixture comprises a range of 50 to 93 percent by weight of tungsten, and 50 to 7 percent by weight of the powdered metal binder. In a specific embodiment of the invention, graphite powder is intermixed with the powdered metal binder to act as a lubricant during formation of the shaped charge liner. The powdered metal binder can be a combination of copper powder, lead, and molybdenum.

Abstract: A method of producing a liner for a shaped charge comprising mixing a composition of powdered metal with plasticizers and binders to form a paste. The paste is then particulated and injected into an injection mold. The paste is molded into a molded liner shape and then chemically treated to remove plasticizers and binders from the molded liner shape. After being removed from the injection mold the molded liner shape is sintered inside of a furnace. The powdered metal composition can be comprised of a mixture of from 60% to 97% by weight of powdered heavy metal and from 40% to 3% by weight of cobalt, or the powdered metal composition can be comprised of a mixture of from 60% to 97% by weight of powdered heavy metal and from 40% to 3% of copper, the preferred heavy metal being tungsten.
