A detonation wire has a firing module connector at one end and a firework connection assembly at another end. The firework connection assembly has a connector housing having a plurality of sections at least partially surrounding and defining an ignition chamber. The firework connection assembly also has one or more firework igniters positioned at least partially within the ignition chamber. A firework igniter is operable to activate an ignition element of a respective firework placed into engagement therewith. Other examples also are described.

This disclosure provides a stackable propellant module for use inside of a gas generation canister. The modules are designed to enable them to be individually fired rather than as a unitary mass, as done in conventional configurations. This enables the generation of a controlled pressure profile rather than an uncontrolled pressure profile determined by the environmental conditions downhole, such as temperature and pressure.

An initiator head assembly may include a body and an electrical contact component positioned proximal to the body. The body may include a head extending from a base, and a platform extending from the head, and the body may be injection molded as a unitary component. The electrical contact component may include a line-in portion positioned proximal to the platform and a ground portion positioned proximal to the head. The electrical contact component may be formed integrally with the body such that it is anchored in a fixed position in the body. An initiator for a perforating gun assembly may include the initiator head assembly and a shell coupled to the initiator head assembly.

Disclosed is a magazine apparatus including a first magazine and a second magazine. The first magazine is configured for holding, carrying and dispensing first initiation device components. The second magazine is configured for holding, carrying and dispensing second initiation device components. The first magazine and the second magazine are configured to dispense the first initiation device components and the second initiation device components in a corresponding manner such that a dispensed one of the first initiation device components and a correspondingly dispensed one of the second initiation device components can be assembled together to form a structurally complete, unified initiation device for loading into a borehole.

A system and apparatus for plasma blasting comprises a borehole, with a novel blast probe, the probe comprising a high voltage electrode and a ground casing tube separated by a dielectric separator except for an evacuated area where the plasma blast occurs, wherein the opening in the ground casing and the dielectric separator constitute a sliced and elliptical probe shape. The sliced and elliptical shape of the opening focuses a plasma blast in a specific direction and contours, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The blasting media comprises water alone or in combination with other materials. The sliced and elliptical blast probe permit directional aiming of the blast.

A system and apparatus for plasma blasting comprises a borehole, with a novel blast probe, the probe comprising a high voltage electrode and a ground casing tube with a ground and/or electrode deflector. The ground and/or electrode deflector focuses a plasma blast through openings in the probe, directing the blast force away from the ends of the probe, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The blasting media comprises water alone or in combination with other materials. The robust blast probe permits the aiming of the blast outside of the probe.
