    Abstract: A composite drill gun for use in a wellbore environment can include a detonation housing containing a detonation source, a composite carrier containing one or more encapsulated charges, and a detonation train connecting the detonation source to the encapsulated charges. The detonation source and each individual encapsulated charge are all sealed with respect to the wellbore environment, and thus the carrier need not be sealed with respect to the wellbore environment. The carrier can be made out of composite materials without worry of leaks into the interior of the carrier, as the detonation source and encapsulated charges are all sealed with respect to the wellbore environment. The composite carrier can be easily drilled out of the wellbore after detonation.

    Abstract: The present invention discloses a wellbore subassembly with a perforating gun. The wellbore subassembly includes a tubular body and a perforating charge. The tubular body has a wall defining an interior space and an exterior space and the wall has a cavity. In some embodiments, the cavity may be shaped to define a charge socket that receives only a single perforating charge. The perforating charge is configured in the cavity at a location inside the wall. The perforating charge is configured to discharge toward and into the interior space and penetrate into the exterior space by perforating the wall across the interior space from the location of the perforating charge.

The firing head assembly includes a tubular housing, first and second pistons, and a compressible member arranged within a lumen of the tubular housing and positioned between the first and second pistons. According to an aspect, the assembly includes a plurality of upper locking arms and lower locking arms that engage with locking members formed in the tubular housing. The firing head assembly further includes upper and lower shear washers arranged at the second opening of the tubular body, in a sandwich type configuration with respect to the second piston. Pressures within the firing head assembly may be adjusted to activate the firing head assembly to either trigger an explosive reaction or to not trigger the explosive reaction.

    Abstract: A method and system for preparing or treating a wellbore in conjunction with a perforating operation. The disclosed perforating gun system includes one or more perforating guns between an uphole flow sub and a downhole flow sub. The uphole flow sub and the downhole flow sub are connected by a fluid bypass that permits fluid to be pumped into the wellbore below the perforating guns. Before perforation, formation-compatible fluid may be pumped through the first and second flow subs via the fluid bypass to displace fluid and debris that may interfere with or cause unwanted damage during perforation. Alternatively, the fluid may be a treating fluid selected to dissolve debris within the wellbore. Following perforation, the fluid may be circulated through the wellbore to remove or dissolve debris created during the perforating process.

    Abstract: A first end of a conductive spring is embedded in a wall of a large chamber of a piston housing. The spring is held in tension by a second end of the spring being pinned against a bead contact by a trigger pin. The diameter of the piston and a tensile breaking strength of the trigger pin are selected so that the trigger pin is breakable and the tension in the spring is releasable upon the presence of a predetermined pressure difference between a pressure on the contact side of the piston and a pressure on the pinning side of the piston. Release of tension in the spring closes an electrical circuit.

    Abstract: An isolation sub for use in a perforating system that includes a pressure activated firing head. The isolation sub is set between the pressure source that is used to initiate the firing head. A pressure regulator in the sub is responsive to fluctuations in pressure difference between the pressure source and wellbore and isolates the firing head when the pressure difference is at or approaches a designated pressure difference that could initiate the firing head. The pressure regulator includes a spring loaded piston that seals the firing head from the source pressure before the pressure difference activates the firing head.
