Abstract: Apparatus and methods for deploying fluid tracer material with a perforating gun. An example apparatus may include tracer material shaped to facilitate placement within or in association with a perforating gun, wherein detonation of shaped charges of the perforating gun forms perforation tunnels in a subterranean formation and discharges the tracer material from the perforating gun into the perforation tunnels. An example apparatus may include a perforating gun comprising a plurality of shaped charges and containing tracer material, wherein detonation of the shaped charges forms perforation tunnels in the subterranean formation and discharges the tracer material from the perforating gun into the perforation tunnels. An example method may include deploying tracer material into a subterranean formation via a perforating gun.

Abstract: A planing machine including a base, at least two support columns disposed on the base, and a carriage assembly carrying a cutterhead. The carriage assembly may be mounted on the support columns. At least one of the base and the carriage assembly is movable vertically towards the other of the base and the carriage assembly. The planing machine may have panel mounted on at least one one of the base and the carriage assembly and extending between the carriage assembly and the base housing for preventing user contact with the cutterhead.
