Abstract: A perforating gun with a self-orienting charge cartridge is disclosed for use in oil and gas completions operations. In one or more embodiments, the perforating gun may include a carrier tube within which the self-orienting charge cartridge extends and a conductor sub coupled to the carrier tube. In one or more embodiments, the self-orienting charge cartridge includes a perforating charge and a bearing, and is configured so that the perforating charge is initiable via the conductor sub and the bearing rotationally supports the perforating charge within the carrier tube. A gun string including the perforating gun and one or more additional perforating guns substantially identical to the perforating gun is also disclosed.

Abstract: A perforating gun string includes a release tool, a perforating gun, and a plug. The perforating gun string may include or be part of a downhole tool that is electrically communicable via a control system. A first switch (or “RT switch”) is associated with the release tool and is operably coupled to a first detonator. A second switch (or “gun switch”) is associated with the perforating gun and is operably coupled to a second detonator. A third switch (or “plug switch”) is associated with the plug and is operably coupled to an igniter. A counter system includes a plurality of counters adapted to track usage of one or more switches in the perforating gun string, including the first switch, the second switch, the third switch, or any combination thereof.

In one or more embodiments, the perforating gun may include a carrier tube within which the self-orienting charge cartridge extends and a conductor sub coupled to the carrier tube. In one or more embodiments, the self-orienting charge cartridge includes a perforating charge, a bearing, and a ground conductor, and is configured so that the perforating charge is initiable via the conductor sub, the bearing rotationally supports the perforating charge within the carrier tube, and the ground conductor provides grounding electrical contact with the conductor sub in order to ground the self-orienting charge cartridge directly to the conductor sub. A gun string including the perforating gun and one or more additional perforating guns substantially identical to the perforating gun is also disclosed.

Abstract: A perforating gun used in oil and gas completions operations, the perforating gun including a ballistic interrupter actuable from a disarmed state or configuration, in which ballistic communication between a detonator and a detonation cord is impeded, to an armed state or configuration, in which ballistic communication between the detonator and the detonating cord is permitted. A gun string includes the perforating gun and one or more additional perforating guns substantially identical to the perforating gun.
