Patent number: 11066892Abstract: A blowout preventer includes a main housing containing a through bore. A first chamber is arranged transverse to the through bore. A second chamber is transverse to the through bore and is diametrically opposed to the first chamber. A first shearing device is located in the first chamber and a second shearing device located in the second chamber. The blowout preventer includes a charge that when activated propels each shearing device along its respective chamber and across the through bore into the opposing chamber, such that the first and second shearing devices are adjacent each other.Type: GrantFiled: March 11, 2019Date of Patent: July 20, 2021Assignee: Kinetic Pressure Control Ltd.Inventors: Bobby James Gallagher, Steven Anthony Angstmann, Billy Jack Gallagher

Patent number: 11028664Abstract: A blowout preventer has a main body having a through bore. A housing is mounted to the main body and defines a passage connected to and transverse to the through bore. An isolation ring cutter is initially disposed around the through bore and closes the passage to fluid flow. The isolation ring cutter is movable along the passage and has an opening coincident with the through bore. A piston and gate are disposed in the passage spaced apart from the isolation ring cutter. A propellant charge is disposed between the piston and an end.Type: GrantFiled: February 28, 2020Date of Patent: June 8, 2021Assignee: Kinetic Pressure Control Ltd.Inventors: Bobby James Gallagher, Billy Jack Gallagher

Patent number: 10370914Abstract: A choke and kill system, and a method of adapting a low pressure drilling rig for use in a high pressure application are described. The system has a low pressure stack and a high pressure blowout preventer stack fluidly connected to the low pressure stack. A choke is fluidly connected to a low pressure choke line of the low pressure stack and is connected to a high pressure choke line of the high pressure blowout preventer stack. The choke is adapted to reduce the pressure from the high pressure choke line to the low pressure choke line.Type: GrantFiled: September 22, 2017Date of Patent: August 6, 2019Assignee: KINETIC PRESSURE CONTROL LIMITEDInventors: Steven Anthony Angstmann, Bobby James Gallagher
