A gun assembly for perforating wells comprising a plurality of guns with shape charges aligned centrically by end caps having insulated connector pins for conducting electrical signals and pressure through the end caps while preventing debris from the blast of one gun from entering and damaging the electrical connections and components of the next gun. The end caps being interconnected physically and electrically by specialized intermediate subs.

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.

A steerable sub for controlling an angular orientation of a well tool in a well, the steerable sub including a housing; a steering element attached to the housing and configured (i) to partially extend out of the housing and (ii) to change an orientation relative to the housing; and an actuation mechanism connected to the steering element and configured to change the orientation of the steering element relative to the housing.

A perforating tool includes an encapsulated shaped charge that has a bulkhead with a reduced wall thickness section, a plate having a shallow recess, and a detonating cord having an energetic core. The energetic core forms the plate into an explosively formed perforator when detonated. The plate is positioned to direct the explosively formed perforator into the reduced wall thickness section.
