An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers (percussion caps). An adapter connects the firing actuator to shock tube and channels the ignition force into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and the detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive wave into the adapter, which channels the wave into the shock tube and ignites the shock tube. The explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach structures or other applications.

A propellant container for a perforating gun includes a lower cap, one or more pieces of propellant positioned within the lower cap, wherein at least one of the one or more pieces of propellant defines one or more through-holes, and an upper cap matable with the lower cap to secure the one or more pieces of propellant within the lower cap. A filler material is present within interstitial spaces between the one or more pieces of propellant.

The present disclosure provides a loading tube to be used in a perforating gun. The loading tube is capable of securely engaging with shaped charges while maintaining the structural integrity and being made by injection molding.

A perforation gun assembly may include a single shaped charge holder, the shaped charge holder having a charge receiving structure and at least one projection extending from the charge receiving structure. A detonation cord and a detonator may be connected to the shaped charge holder. A top connector may be configured for connecting to a first base of the shaped charge holder and a bottom connector may be configured for connecting to a second based of the shaped charge holder. The perforation gun assembly may be positioned within an outer gun carrier of a perforation gun, and a tandem seal adapter may be positioned at least in part within the outer gun carrier.

A method and system for a perforating gun having a box by pin perforating gun system using swaged down gun bodies. The box by pin perforating gun system may include a removable cartridge to hold a detonator with a switch and an insulated charge holder as an electrical feed-through.

A modular, stackable charge holder for a perforating gun assembly. The charge holder may include a retention socket for locking a detonating cord in place, and a male connector end and a female connector end for connecting to other modular component(s). The retention socket may include oppositely disposed retention arms, each having a shaped sidewall portion and a corresponding flange extending transversely from a top section of the retention arm. The male and female connector ends may respectively include a phasing protrusion and a phasing hole arranged to facilitate various phase angles between components, and a centrally oriented knob connector and a central bore adapted to interconnect.

A shock tube for propagating and initiating a signal to an explosive charge which includes at least first and second elongate flexible conductors on a body of the detonator to enable two-way communication between the explosive charge and a blasting machine thereby to confirm the status of the detonator prior to sending a fire signal.

The present disclosure relates to a connector for a blast-triggering device, said connector including a connector head in which a rear end thereof is integrally connected with a rear surface of a connector body, an upper surface thereof is formed in a curved surface extending from the rear end thereof to a front end thereof, a tube insertion portion is provided between a lower surface thereof and the connector body so that a plurality of shock tubes is fitted therein, and the front end thereof is separated from the connector body. Thus, it is possible to maintain the shape of the connector during detonation, thereby minimizing the generation of debris and improving the safety at the time of detonation. In addition, it is possible to prevent damage to the plurality of shock tubes, thereby preventing a cut-off phenomenon caused by damaged shock tubes during detonation.

A ballistic transfer system, comprising: a housing, wherein the housing is cylindrical, wherein the housing comprises: a central bore that traverses a length of the housing; a first end; wherein the first end is disposed about a first ballistic apparatus; and a second end, wherein the second end is opposite to the first end, wherein the second end is disposed about a second ballistic apparatus; an alignment insert, wherein the alignment insert is secured into the housing; a first detonation transfer line, wherein a portion of the first detonation transfer line is disposed within the alignment insert; and a second detonation transfer line, wherein a portion of the second detonation transfer line is disposed within the alignment insert.

According to an aspect a bulkhead assembly is provided having particular application with a downhole tool, in particular for oil well drilling applications. The bulkhead assembly includes a bulkhead body and an electrical contact component disposed within the bulkhead body, wherein at least a portion of the electrical contact component is configured to pivot about its own axis, without compromising its ability to provide a pressure and fluid barrier. In an embodiment, a ground apparatus is provided to provide an electrical connection for at least one ground wire. The ground apparatus may be positionable on the bulkhead body of the bulkhead assembly. In an aspect, a downhole tool including the bulkhead assembly and ground apparatus is also generally described.
