Abstract: A wireline derrick has a telescopically arranged frame, a sheave, a winch, and pressure control equipment. Pressure control equipment (PCE) is positioned within the frame. An upper section of the derrick can extend and retract relative to a lower section. When the wireline derrick is in the retracted position, an upper PCE assembly is positioned adjacent to the lower PCE assembly. The upper PCE assembly is laterally moveable, such that when the wireline derrick is in the extended position, the upper PCE assembly may be moved into and out of axial alignment with the lower PCE assembly. When in a fully deployed condition, the lower end of the upper PCE assembly is removably coupled to the upper end of the lower PCE assembly. A transport trailer is adapted to move the wireline derrick from a horizontal position to a vertical position and cause the upper section to extend and retract.

Abstract: An automated system and process for vertically assembling and disassembling a wireline bottom hole assembly (BHA) comprises one or more robots, and a structure comprising a receiver assembly. The receiver assembly comprises a conduit adapted to permit respective bottom hole assembly sections to be moved between an interior and an exterior of the structure. The robots are structured to retrieve bottom hole assembly components from bins and assemble bottom hole assembly sections that make up a bottom hole assembly. The robots move each section to the receiver assembly to connect the section to a partial assemblage comprising a wireline and respective subassemblies. After use of the BHA, the robots disassemble sections of the BHA and move the components to used component bins and/or to a dispensing shoot leading to a waste container. The system has modules adapted to provide information regarding the status of components and the BHA.

Abstract: A perforating gun includes a charge tube, a switch carrier body, and a pin contact spacer. The switch carrier body houses an addressable switch, a spring tube which holds a spring, a detonation block, a removable interrupter, and a pin contact spacer supporting a pin contact assembly. The spring biases a switch contact terminal towards an outer surface of the switch carrier body, and the switch contact terminal is electrically connected to the addressable switch. The interrupter includes first and second portions, and is temporarily adhered to the switch carrier body such that the first portion covers the switch contact terminal and the second portion extends between a detonation cord and an instantaneous detonator in the detonation block. A first end of the charge tube is positioned around the switch carrier body, and a second end of the charge tube is secured to the pin contact space.
