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.

Abstract: In one example, a downhole system includes a housing configured to be releasably connected to a tether, projectile fire control circuitry disposed within the housing, a block chamber connected to the housing, and the block chamber includes one or more reloadable chambers each configured to be loaded with a respective projectile, and a firing system operable to directly, or indirectly, control the firing of a projectile, in response to a command issued by the projectile fire control circuitry.
