Abstract: Various exemplary embodiments of an encapsulated shaped charge (100) may include a charge case (110), a charge lid (120) covering an open end of the charge case, and an external clip assembly connected to each of the charge case and the charge lid. The charge case may house explosive material (111) and a shaped charge liner (112). The external clip assembly may include one or more clips (140) respectively connected to each of a retainer ring (130) positioned on the charge lid, and the charge case. The retainer ring may be formed from a material that will melt or burn when exposed to fire. According to the exemplary embodiments, melting or burning the retainer ring can release the one or more clips from the retainer ring and/or charge lid.

Abstract: A perforating gun apparatus comprising a bulkhead connector located between an upper gun body thread and lower gun body thread. The bulkhead connector has seals in sealing arrangement with an upper gun body and a lower gun body with a support sleeve in contact with an inner groove support shoulder on the lower gun body. The support sleeve is radially deformable into the inner groove by a shockwave produced by firing the charges in the lower gun section. The deformation of the support sleeve attenuates the impact of the shockwave on the threaded connection. The bulkhead connector isolates the threaded connection from the pressure spike. The deformed support sleeve attenuates the shockwave from the charges firing in the upper gun section and transfers the resultant force away from the threaded connection.

Abstract: A method for completing a subterranean formation includes conveying a perforator assembly into a borehole drilled in the subterranean formation. The perforator assembly includes at least one shaped charge and at least one tracer package that includes at least one fluid production tracer material and a tracer injector. The method further includes forming at least one tunnel in a production structure by detonating one or more shaped charges and injecting the at least one fluid production tracer material into the formation using the tracer injector after the detonation of the at least one shaped charge. The at least one production tracer material physically associates with at least one resident fluid in the subterranean formation.
