In aspects, the present disclosure provides a perforating gun that includes a carrier tube, and a charge tube assembly. The carrier tube includes a bore and a groove formed along an inner surface. The charge tube assembly is disposed in the bore of the carrier tube and includes a charge tube, an alignment end plate, an insertion end plate, a retention member, shaped charges, and a detonating cord. The charge tube has a plurality of shaped charge openings, a plurality of post openings, a first end, and a second end. The alignment end plate is connected to the first end of the charge tube. The insertion end plate is connected to the second end of the charge tube. The shaped charges are disposed in each of the shaped charge openings. Each shaped charge has a post projecting out of one post opening. The detonating cord is connected to each of the projecting posts.

Perforating gun

A well tool () includes a perforating gun (), a sealing element (), at least one pressure sensor (), a detector (), a controller (), and an anchor (). The perforating gun () perforates the wellbore tubular in response to a firing signal. The sealing element () is connected to the perforating gun () and generates a pressure differential thereacross. The at least one pressure sensor () is associated with the sealing element () and detects a surface transmitted pressure signal. The detector () detects at least one marker () positioned along the wellbore () and which includes a perforating marker () associated with a perforating depth. The controller () is in signal communication with the at least one pressure sensor () and the detector () and is configured to transmit the firing signal to the perforating gun () only after: (i) the at least one pressure sensor () detects the surface transmitted pressure signal, and (ii) the detector () detects the perforating marker (). The anchor () is connected to the perforating gun () and selectively locks the perforating gun () to the wellbore tubular.

An apparatus for activating a wellbore tool may include a first sub, gas transfer sub, and a second sub. The first sub has an igniter that generates a flame output that ignites a power charge. The power charge generates a high pressure gas when ignited by the flame output. The gas transfer sub has a first end receiving a portion of the power charge, a longitudinal bore, and a plurality of flow passages radiating from the longitudinal bore. The flow passages provide fluid communication between the longitudinal bore and the first sub. The second sub includes a shaft having a first end connectable with the gas transfer sub.

Devices and related methods for actuating wellbore tools with a pressurized gas

An apparatus and a method for cutting a wellbore tubular may include an upper section and a lower section mating at a juncture plane defined by a plane transverse to the longitudinal axis of the wellbore tubular. Each section may include a support plate having a passage, a liner positioned adjacent to the support plate, and an energetic material disposed between the support plate and the liner. An initiator having a shaft may be positioned in the passages of the upper section and the lower section.
