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 detonator module comprising: a housing with a first housing half and a second housing half, a detonator contained within the housing, a child board comprising a terminal header, wherein the child board is contained within the housing and the first housing half exposes the terminal header to an exterior of the housing, a switch mounted to an exterior surface of the housing, and a plurality of switch leads connecting the switch to the terminal header.

Abstract: A wireline tool connection comprising a wireline top sub and a tandem sub; wherein the wireline top sub further comprises a first pin end, a first box end, wherein the first box end further comprises an internal threads, and a bore that extends from the first pin end partially through the body of the wireline top sub. The tandem sub further comprises threads, an electric feedthrough, and a pressure barrier. The tandem sub and wireline top sub are connected via the threads of the tandem sub and the internal threads of the wireline top sub.

Abstract: A top set plug for sealing against a casing of a well. The plug includes a mandrel having a throughout bore that extends from a top end to a bottom end; a connecting mechanism located at the top end of the mandrel; a sealing element located around the mandrel and configured to be pushed toward an internal wall of the casing; an upper wedge configured to push the sealing element against the casing; and a slip ring configured to push the sealing element over the upper wedge and also to engage the inner wall of the casing with buttons for preventing the plug to slide along the casing.

Abstract: A sub connects a gun string to a hydraulically activated setting tool for setting an auxiliary tool in a well. The sub includes a housing that prevents a well fluid from entering inside the housing; a plug that covers a hole made in a wall of the housing; and an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between an outside and the inside of the sub.

Abstract: A setting tool (402) for setting a plug in a well, the setting tool (402) including a body (404) extending along a longitudinal axis X; a rod (408) extending along the longitudinal axis of the body (404), from an upstream end (402B) to a downstream end (402A) of the body (404); a chamber (406) formed at the downstream end (402A) of the body; and a restriction element (450) located in the chamber (406). The rod (408) extends through the entire chamber (406) and the restriction element (450) is located between the rod (408) and a wall (404A) of the chamber (406).

Abstract: A downhole isolation system for sealing a well, the downhole isolation system including a setting tool having an internal chamber; a first restriction element placed within the internal chamber; and a second restriction element placed within the internal chamber, separate from the first restriction element.

Abstract: A hydraulically activated setting tool for setting an auxiliary tool in a well, the setting tool including a housing that prevents a well fluid from entering inside the housing; a floating piston placed inside the housing and closing an end of a pressure chamber; an attached piston placed inside the housing and configured to actuate the auxiliary tool; a fluid chamber located between the floating piston and the attached piston, wherein the fluid chamber holds a fluid; and a communication element configured to establish a fluid communication between an outside and an inside of the housing. The fluid communication makes a well fluid in the well to directly act on the floating piston.
