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.
Claims33
A penetrator assembly, comprising:
- a penetrator;
- a propellant operably positioned with respect to the penetrator;
- an ignitor in operable communication with the propellant;
- and
- an electrical conductor configured and arranged to carry electrical power to a primer, and a first end of the electrical conductor is embedded into the propellant, and the electrical conductor passes through, or around, the penetrator.
A dispenser, comprising:
- a body comprising a chamber, and the body is configured to be removably received in a carrier;
- a barrel defined within, and integral with, the chamber, and the barrel is configured to receive a penetrator assembly;
- and
- a wireway defined by the chamber and configured to enable insertion of an electrical conductor into the barrel, and the wireway is configured and arranged to enable insertion of the electrical conductor into an open end of the barrel.
A carrier, comprising:
- a body having a configuration that comprises a bottom half and a top half that are releasably connectible together;
- and
- a receptacle defined within the body and configured to removably receive a dispenser and a penetrator assembly, and respective portions of the receptacle are defined by the bottom half of the body, and the top half of the body.
An apparatus, comprising:
- a penetrator assembly, comprising:
- a penetrator;
- a propellant operably positioned with respect to the penetrator;
- an ignitor in operable communication with the propellant;
- and
- an electrical conductor configured and arranged to carry electrical power to a primer, and a first end of the electrical conductor is embedded into the propellant, and the electrical conductor passes through, or around, the penetrator;
- a dispenser configured to removably receive the penetrator assembly;
- and
- a carrier configured to removably receive the dispenser.
