A perforation tool, and a bulkhead member for a perforation tool, are disclosed. The perforation tool has a loading tube, an initiator module, and a bulkhead member connected between the loading tube and the initiator module. The bulkhead member has a hollow body member with a central transverse plate having a central bore through the transverse plate along a longitudinal axis of the body member and an electrical conductor disposed in the central bore, the electrical conductor having a pin connection at a first end thereof and a box connection at a second end thereof.

An orienting sub including a hub retainer, a gun sleeve, a locking sleeve, and an electric conductor assembly. In several embodiments, the orienting sub couples a first perforating gun to a second perforating gun. The first perforating gun, the second, perforating gun, and the orienting sub may together form a well perforating system for perforating a wellbore that traverses a subterranean oil and gas formation.

In one example, an apparatus includes a TLT (Time of Flight (TOF)/LiDAR tool) with one or more optical transmitters and optical receivers that are operable to cooperate to obtain data concerning a downhole feature when the apparatus is deployed in a downhole environment. This apparatus further includes a first device operable to determine a position, speed, and/or orientation, of the TLT, when the TLT is deployed in the downhole environment, a second device configured to store locally and/or transmit the data to a location on a surface, a power source connected to the TLT, the first device, and the second device, and a housing within which the TLT, first device, second device, and power source are disposed, and the housing includes a connector configured to interface with a piece of downhole equipment.

A downhole well tool assembly can include a perforator and a selectively openable and closable perforation plug discharge port. A method of perforating and treating multiple formation zones of a well in a single trip of a downhole well tool assembly into the well can include positioning the downhole well tool assembly at a zone, closing a perforation plug discharge port of the downhole well tool assembly, perforating the zone, treating the zone, opening the perforation plug discharge port, deploying perforation plugs into the well via the perforation plug discharge port, plugging perforations in the zone with the perforation plugs, positioning the downhole well tool assembly at a subsequent zone, closing the perforation plug discharge port, perforating the subsequent zone, and treating the subsequent zone.
