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.

Integrated wiring gun and method

An interchangeable module configured to be used in an integrated perforating gun and setting tool system, the interchangeable module having a body having a chamber, a first electrical connection located at a first end of the chamber, and a second electrical connection located at a second end of the chamber. The first end is opposite to the second end. An addressable switch located inside the chamber, the addressable switch has a digital address. A connection unit located inside the chamber and configured to electrically connect the addressable switch to an initiating device. The interchangeable module is configured to be used (1) between a first gun cluster and a second gun cluster and (2) between a distal gun cluster and a setting tool, and the first and second electrical connections are electrically connected to the addressable switch.

Integrated perforating gun and setting tool system and method

A downhole tool for connecting and releasing portions of a tool string includes a housing; an electronics assembly; an activation mechanism; a valve assembly and a set of retainer dogs to connect and release a neck of another tool. The downhole tool may also include one or more measurement sensors for measuring a parameter and transferring one or more measured parameter values to the surface of the well.

Release tool for downhole operations

A detonator block for housing a detonator has a body configured to host the detonator; the body having a first end that is configured to be attached to a sub; the body having a second end, opposite to the first end, and configured to connect to a gun; and a printed circuit board located inside the body, the printed circuit board being electrically connected to the detonator. The body has a holder that is configured to hold the detonator inside the body.

Perforating gun system and method

A braking and setting device is configured to slow down a movement of a tool in a well and to fix the tool relative to the well. The braking and setting device includes two or more arms configured to extend from the tool, toward the well, to brake the movement of the tool along a longitudinal axis X; a movable piston configured to be hosted fully within the tool and to move only when a well fluid acts on a base portion of the movable piston, while a tip portion of the movable piston pushes away the two or more arms; and an actuation mechanism configured to establish a fluid communication between the well fluid and the base portion of the movable piston. The movable piston moves exclusively due to a force exerted by the well fluid on the movable piston.

An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate includes a base with a 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. Each of the set of tube tabs has a retaining lip and is generally oriented in a direction of the longitudinal axis. The endplate may include an optional 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.

An interchangeable module is configured to be used in an integrated perforating gun and setting tool system. The interchangeable module includes a body having first external threads; an addressable switch located inside the body; and a connection unit located inside the body and configured to electrically connect to an initiating device. The interchangeable module is configured to be used (1) between a first gun cluster and a second gun cluster and (2) between a distal gun cluster and a setting tool.

A quick connect system for connecting a first downhole tool to a second downhole tool, the quick connect system including a quick connect device configured to be mechanically attached to the first downhole tool; and a top sub configured to be mechanically attached to the quick connect device and also to the second downhole tool. The top sub has a first bulkhead element that prevents a high pressure gas from the second downhole tool to damage the quick connect device.
