Abstract

A dispenser includes a body that defines a chamber and a barrel that communicate with each other, and a penetrator assembly configured to be received in the chamber. The penetrator assembly includes a penetrator, a propellant operably positioned with respect to the penetrator, a primer in operable communication with the propellant, and an electrical conductor configured and arranged to carry electrical power to the primer. The dispenser may be positioned in a downhole location such as a wellbore, and the penetrator assembly may be fired so that the penetrator perforates a casing in the wellbore.

Claims (20)

1. A dispenser, comprising:

a body that defines a chamber and a barrel that communicate with each other; and

a penetrator assembly configured to be received in the chamber, and comprising:

a penetrator;

a propellant operably positioned with respect to the penetrator;

a primer in operable communication with the propellant; and

an electrical conductor configured and arranged to carry electrical power to the primer, wherein the electrical conductor comprises a wire passing through, or around, the penetrator.

2. A penetrator assembly, comprising:

a penetrator;

a propellant operably positioned with respect to the penetrator;

a primer in operable communication with the propellant; and

an electrical conductor configured and arranged to carry electrical power to the primer, and a first end of the electrical conductor is embedded into the propellant, and the electrical conductor passes through the penetrator and extends out an end of the penetrator,

wherein the penetrator assembly is configured to be received in a chamber of a dispenser.

3. A dispenser, comprising:

a body that defines a chamber and a barrel that communicate with each other; and

a penetrator assembly configured to be received in the chamber, and comprising:

a penetrator that defines a passageway extending through the penetrator;

a propellant operably positioned with respect to the penetrator;

a primer in operable communication with the propellant; and

an electrical conductor configured and arranged to carry electrical power to the primer, and the electrical conductor passes through the passageway.
