Abstract:
An apparatus and method for locking a detonating cord against a shaped charge. In order to detonate a shaped charge in a perforating gun a continuous detonating cord is placed adjacent to each shaped charge. Holding a detonating cord in place is crucial to ensuring that all of the shaped charges detonate when the detonating cord detonates. Otherwise, unexploded ordinance may end up being brought to the surface, causing a serious safety issue. Furthermore, current means of fastening the shaped charge to the detonating cord require multiple cumbersome means.
Abstract:
A method and apparatus for containing one or more shaped charges in a single plane, arrayed about the center axis of a gun body, and detonated from a single initiator in a shaped charge cluster assembly.

Abstract:
A box by pin perforating gun system using swaged down gun bodies, a removable cartridge to hold a detonator and switch, and an insulated charge holder as an electrical feed-through.
Abstract:
An apparatus and method for connecting a shaped charge retainer to a shaped charge connecting that to a charged tube in a perforating gun for use downhole.

Abstract:
A shaped charge retainer ring for use in containing the liner of a shaped charge and the explosive material. Generally, when completing a subterranean well for the production of fluids, minerals, or gases from underground reservoirs, several types of tubulars are placed downhole as part of the drilling, exploration, and completions process. These tubulars can include casing, tubing, pipes, liners, and devices conveyed downhole by tubulars of various types. Each well is unique, so combinations of different tubulars may be lowered into a well for a multitude of purposes.
Abstract:
A jet cutter venting apparatus and method for venting gases generated during deflagration. The venting apparatus and method including vent grooves inside the jet cutter providing a pathway for deflagration gases to escape. The venting apparatus and method also may include using notches or holes placed inside the jet cutter to facilitate the venting of gases during deflagration. The venting of the gases during deflagration facilitates pressure relief within the jet cutter and increases safety from accidental detonation during a fire.

Abstract:
A link jet system using a combination of a one piece cast zinc alloy case and interlocking linked shaped charges for minimizing debris left in a downhole wellbore when fired, reducing components in system, and providing an easy method for changing the shaped charge phase.
