Abstract: A housing for an electrical component of a gun system is disclosed. The housing includes a housing body, an uphole bulkhead, and a downhole bulkhead. The housing body defines a cavity. The uphole bulkhead is disposed at least partially within the cavity. The downhole bulkhead is disposed at least partially within the cavity and opposite to the uphole bulkhead. The downhole bulkhead includes an electrical contact extending between a first end and a second end of the downhole bulkhead. The cavity, the uphole bulkhead, and the second end of the downhole bulkhead define a sealed volume configured to receive and isolate the electrical component. The electrical contact is configured to be electrically connected to the electrical component.

Abstract: A downhole tool for sealing a well includes a push ring, a first slip ring located adjacent to the push ring, a first wedge located adjacent to the first slip ring and configured to radially push the first slip ring and separate the first slip ring into individual parts, and a sealing element located adjacent to the first wedge and configured to seal the well. An upstream end of the first slip ring and a downstream end of the push ring form a wavy interface when in contact. The wavy interface locks the first slip ring relative to the push ring to prevent a rotation of the first slip ring relative to the push ring.

Abstract: A centralizing device is configured to centralize/decentralize an associated tool in a well. The centralizing device includes a body that extends along a longitudinal axis X, the body having a bore that extends from one end to another end of the body; a first piston shaped as a cylinder and provided around a central portion of the body; a second piston shaped as a cylinder and provided around the central portion of the body; a bridge provided around the central portion of the body, between the first and second pistons; and a pair of arms, each arm being attached with one end to a corresponding one of the first and second pistons and with another end to each other. The second piston, the bridge, and the central portion of the body define a sealed chamber, which is sealed from the ambient.

Abstract: An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate may include a base with first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. The endplate may include a carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.

Abstract: A switch assembly, which is part of a chain of switch assemblies. The switch assembly includes a micro-controller PB that has no address, a thru-line switch, and a detonator switch. The micro-controller PB is configured to directly communicate with an upstream or downstream switch assembly through a pulsing scheme, and the micro-controller PB receives no command from a surface controller.

Abstract: A convertible and addressable switch assembly includes an interface (I/O) configured to connect to a controller along a telemetry system; and a processor connected to the interface (I/O). The processor is configured to receive a command from the controller, along the telemetry system, to change a first value of a mode status variable to a desired second value, wherein the first value is associated with a first operating mode of the switch assembly and the second value is associated with a second operating mode, which is different from the first operating mode; change the first value to the second value within the switch assembly; and store in a non-volatile memory, at the switch assembly, the second value of the mode status variable.

Abstract: A perforating gun for making perforations in a well, the perforating gun including a carrier extending along a longitudinal axis X and having a bore; a tube extending along the longitudinal axis X and having a radius smaller than a radius of the carrier so that the tube slides inside the bore of the carrier; a shaped charge placed inside the tube and configured to make a hole through the carrier; and a scallop formed in a body of the carrier, corresponding to a location of the shaped charge along the longitudinal axis X. The scallop has a side surface that makes an angle α with the longitudinal axis X, and the angle α is different from 90 degrees.
