Publication number: 20250347202Abstract: A perforating gun includes a gun assembly and a gun barrel. The gun assembly includes a charge tube comprising at least one shaped charge. A pin contact assembly is operably attached to a first end of the charge tube and includes a contact spacer and a through pin configured to provide electrical communication between respective perforating guns. An addressable switch assembly is attached to a second end of the charge tube and comprises an addressable switch and a detonator. The gun assembly is situated within the gun barrel and is configured to self-orient inside the gun barrel.Type: ApplicationFiled: April 17, 2025Publication date: November 13, 2025Inventors: John P. Roach, Chris Payson

Patent number: 12454879Abstract: 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.Type: GrantFiled: June 17, 2024Date of Patent: October 28, 2025Assignee: Reach Wireline, LLCInventors: John P. Roach, Daniel Tollefson, Chris Payson, Jerred Smith

Patent number: 12385345Abstract: A wireline release head system includes a housing, a cutter box situated within the housing, a fire control switch, and a wireline extending through the cutter box and in electrical communication with a control unit and the fire control switch. The cutter box includes a piston assembly operable to move within a first track and a cutter knife operable to move within a second track. The second track is angled relative to the first track. The fire control switch is in communication with a fire detonator, which is selectively activatable to detonate a power charge. An electrical signal selectively sent through the wireline from the control unit to the fire control switch detonates the power charge, which causes the piston assembly to move within the first track and contact the cutter knife causing the cutter knife to move within the second track, thereby severing the wireline.Type: GrantFiled: July 26, 2024Date of Patent: August 12, 2025Assignee: Reach Wireline, LLCInventors: John P. Roach, Daniel Tollefson, Chris Payson
