Penetrator and dispensers and methods of use
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.

15. The dispenser as recited in claim 14 , wherein the chamber comprises a block that comprises one or more barrels, and each of the barrels is configured to receive one or more penetrators.
16. The dispenser as recited in claim 14 , wherein the dispenser comprises a perforation gun.
17. The dispenser as recited in claim 14 , wherein the dispenser is integrated into a perf gun.
18. The dispenser as recited in claim 14 , wherein the dispenser is configured to be removably received in a perf gun.
19. The dispenser as recited in claim 14 , wherein the dispenser is reusable after a penetrator of a penetrator assembly has been fired from the barrel.
20. The dispenser as recited in claim 14 , wherein the barrel is configured to removably receive a penetrator assembly that comprises a penetrator whose length is in a range of 0.5 inches to 1.00 inches.
21. The dispenser as recited in claim 14 , wherein when the dispenser is positioned in a downhole location, an interior of the barrel is open to environmental conditions in the downhole environment.
22. The dispenser as recited in claim 14 , wherein the dispenser includes the electrical conductor.
23. The dispenser as recited in claim 14 , wherein a firing board is integrated into the dispenser and is configured to connect to an electrical conductor.
24. 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.
25. The carrier as recited in claim 24 , wherein a longitudinal axis defined by the body is perpendicular to a longitudinal axis of the receptacle.
26. The carrier as recited in claim 24 , wherein the top half of the body comprises a geometric feature configured to interact with a corresponding geometric feature of a penetrator assembly to retain a penetrator assembly in the receptacle.
27. The carrier as recited in claim 24 , wherein the body defines an opening configured and arranged to align with a barrel of a penetrator assembly when the penetrator assembly is disposed within the receptacle.
28. The carrier as recited in claim 24 , wherein a seam defined by the top half and the bottom half is perpendicular to a longitudinal axis of the receptacle.
