Patent number: 10393616Abstract: A method and apparatus for testing blowout preventers for leaks involves maintaining a constant pressure in the portion of the blowout preventer to be tested. A sensor is connected to a controller for maintaining a constant pressure within the blowout preventer. Any amount of fluid introduced into or removed from the blowout preventer in order to maintain constant pressure is measured and is an indication of the leak rate in the blowout preventer. Additionally vibration instrumentation may be used to detect the location and amplitude of vibrations emitted by the test fluid passing from a high pressure regime to the low pressure regime across a leak path.Type: GrantFiled: January 15, 2019Date of Patent: August 27, 2019Assignee: HilFlo, LLCInventors: Clifford L. Hilpert, Jeffrey L. Hilpert

Publication number: 20190049331Abstract: A method of pressure testing a closed hydraulic system for leaks includes heating or cooling pressure intensification fluid before it enters the closed hydraulic system under pressure. The closed hydraulic system may be for example a blowout preventer for an oil/gas well, a manifold system or tubulars. The intensification fluid is heated or cooled to a temperature at or near the temperature of the fluid within the closed hydraulic system.Type: ApplicationFiled: October 16, 2018Publication date: February 14, 2019Applicant: HilFlo, LLCInventors: Clifford Lee Hilpert, Jeffrey Lee Hilpert, Lewis Jackson Dutel, Laura Tufts Meyer

Patent number: 10190381Abstract: A method and apparatus for activating a safety device of a blowout preventer utilizes a variable ratio rotary energy controller. The controller automatically adjusts the pressure of the fluid for activating the safety device thereby conserving the amount of energy required for each activating cycle. The controller includes a variable displacement hydraulic motor coupled to a variable displacement hydraulic pump. A system for recharging the activating fluid circuit allows for the actuating system to be reused as needed.Type: GrantFiled: June 8, 2015Date of Patent: January 29, 2019Assignee: HilFlo, LLCInventors: Clifford Lee Hilpert, Jeffrey Lee Hilpert

Publication number: 20190025152Abstract: A method and apparatus for testing a blowout preventer which includes a plurality of safety devices and an assembly of fluid control valves that are remotely actuatable to an open and closed position for controlling flow of drilling fluids into a well includes a hydraulic power unit control station for remotely and selectively actuating one or more safety devices and fluid control valves to a test orientation. A hydrostatic test system supplies fluid under first and second test pressure and documents any pressure loss due to fluid leaks within a closed system.Type: ApplicationFiled: September 20, 2018Publication date: January 24, 2019Applicant: Hilflo, LLCInventors: Clifford Lee Hilpert, Jeffrey Hilpert

Publication number: 20140235420Abstract: A torque sensing device capable of measuring the force exerted by a torque arm on a lever is positioned between the torque arm and the lever. The torque arm is connected to the pinion of a planetary gearbox for rotating the bowl and screw conveyer of a decanter centrifuge at different speeds. The torque sensing device measures the torque between the pinion gear and the planetary gearbox. The sensor can be connected to a controller which can reduce the flow of the liquid/solid mixture to the decanter centrifuge thereby/reducing the torque and avoiding substantial damage to the planetary gearbox.Type: ApplicationFiled: April 28, 2014Publication date: August 21, 2014Applicant: HilFlo, LLCInventor: Jeffrey L.
