An explosive charge assembly comprises a housing, a liner disposed on a face of an explosive charge, an opening through the liner disposed at the apex, and a lip disposed around the perimeter of the opening. The liner forms an apex and a mouth opposite the apex, and the liner and the explosive charge are disposed in the housing. The explosive charge is disposed between the liner and the housing, and the lip extends from the liner in a direction towards the mouth.

Jet perforating device for creating a wide diameter perforation

A shaped-charge liner for a shaped-charge assembly is provided. The shaped-charge assembly includes a housing, a liner, and explosive material between the housing and the liner. The liner includes an apex portion that has an opening and that defines a fold around the opening. The explosive material supports the apex portion.

Shaped-charge liner with fold around opening

A shaped-charge liner for a shaped-charge assembly is provided. The shaped-charge assembly includes a housing, a single liner, and explosive material between the housing and the liner. The single liner includes an apex portion constructed from a first material and a skirt portion made from a second material that is different than the first material.

Hybrid big hole liner

A perforation tool comprises an explosive charge comprising an explosive focal axis, a tool body containing the explosive charge, and a flowable material carried with the tool and disposed along the explosive focal axis. The flowable material is configured to be released by detonation of the explosive charge and flow to create at least a partial barrier to flow through the aperture in response to the perforation of the tool body by the explosive charge to form an aperture in the tool body.

Wellbore perforation tool

A perforating gun system comprises at least one charge disposed within a gun body, and a first sleeve disposed within the gun body about the at least one charge. The first sleeve comprises a first expansion section, and the first sleeve is configured to undergo non-uniform expansion in response to the detonation of the at least one charge.

Perforating gun debris retention assembly and method of use

A perforation gun. The perforation gun comprises a tool body, the tool body defining at least one shouldered hole wherein the shouldered hole comprises a hole through a wall of the tool body and a shoulder that is thinner than the wall of the tool body and at least one perforating explosive charge disposed within the tool body.

Pressure limiting device for well perforation gun string

A method of making an explosive charge liner comprises introducing powdered material into a basin defined by a die block, where a punch is shaped to interact with the basin, excluding the powdered material from a central portion of the basin, pressing the punch into the powdered material in the basin to form the explosive charge liner, and removing the explosive charge liner from the die block. The explosive charge liner comprises an aperture in an apex area of the explosive charge liner corresponding to the central portion when removed from the die block.

High density powdered material liner

A die set for forming explosive charge liners from powdered material comprises a die block defining a basin and a punch shaped to interact with the basin. The die block and the punch are configured to exclude powdered material from a center axis of the basin. An apparatus comprises a deep-penetrating explosive charge liner formed of powdered material held together by green strength having a hole in a narrow end of the liner.

A wellbore perforation tool comprises an explosive charge, a tool body containing the explosive charge, and a flowable material carried with the tool. The flowable material is released by detonation of the explosive charge and, after perforation of the tool body by the explosive charge to form an aperture in the tool body, flows to form at least a partial barrier of the aperture.

A short arc lamp driving circuit includes a trigger boosting circuit, a flash current control circuit, and a closed loop exposure control and calibration circuits that, when combined, can produce short pulses of light with short time separation, quasi-continuous illumination light, and meanwhile, an extremely large dynamic range of delivered and/or calibrated light power or energy.

Short arc lamp driver and applications

An improved perforating gun having a tubular housing, a tubular carrier and a charge carried by the tubular carrier. The tubular carrier comprises an inside diameter, an outside diameter and an opening disposed between the inside diameter and the outside diameter. The charge comprises a forward end positioned in the opening between the inside diameter and the outside diameter. The tubular carrier increases a collapsible-pressure rating for the housing and positions the charge closer to the formation.

Perforating gun

A perforating apparatus () includes a plurality of shaped charges () each having an initiation end and a discharge end. A detonating cord () is operably coupled to the initiation ends of the shaped charges (). A carrier () contains the shaped charges (). The carrier () includes at least one discharge location corresponding to the discharge ends of the shaped charges () when the perforating apparatus () is in its operable position. The discharge location has first and second material layers () wherein the second material layer () exhibits resilient recovery such that an opening created by a jet formed from detonating one of the shaped charges () in the second material layer () is smaller than an opening created by the jet in the first material layer (), thereby retaining debris in the perforating apparatus () with the second material layer ().

Debris retention perforating apparatus and method for use of same

A perforating apparatus () includes a plurality of shaped charges () each having a case, an initiation end and a discharge end. A detonating cord () is operably associated with the initiation ends of the shaped charges (). An energy absorbing charge holder () has a gas expansion region and a detonating cord receiving area to receive the detonating cord therein (). The energy absorbing charge holder () also has a plurality of charge receiving locations that closely receive the shaped charges () therein such that upon detonation of the shaped charges (), energy is transferred from the cases of the shaped charges () to the energy absorbing charge holder (), thereby reducing fragmentation of the cases.
