Abstract: In one example, a method includes running a downhole system into a downhole environment that comprises a wellbore, and the downhole system is configured such that a reusable plug of the downhole system is positioned uphole of a perforation gun of the downhole system, then, with the perforation gun, perforating a casing at a stage of the wellbore, and the perforating is performed using a projectile, and the perforating is performed by firing the projectile from a chamber of the perforation gun.

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, 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.

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.

Abstract: A measurement device, including a doppler LiDAR unit that includes an optical transmitter operable to transmit a signal, and which further includes an optical receiver operable to receive a backscatter signal that includes a portion of the signal, and the measurement device also includes a processor operable to determine a doppler shift as between the signal and the backscatter signal, and use the doppler shift to determine a volumetric flow rate of a fluid to which the signal is directed, and from which the backscatter signal is received.
