Patent number: 8118088Abstract: A safety valve system includes a safety valve having an actuator and a line connected to the actuator. The safety valve is operable by opening the line in the well, with the line being free of any connection to a surface control system. Another safety valve system includes multiple safety valves. An actuator of each safety valve is connected to an actuator of another safety valve via a line. A biasing force in each of the actuators is operative to close the respective one of the safety valves in response to opening of the line. The biasing force is produced at least in part by hydrostatic pressure in a well.Type: GrantFiled: September 8, 2009Date of Patent: February 21, 2012Assignee: Halliburton Energy Services, Inc.Inventors: Adam D. Wright, Vincent P. Zeller, Harold W. Nivens, Roger L. Schultz

Patent number: 7950277Abstract: An apparatus for actuating a pressure delivery system of a fluid sampler. The apparatus includes a housing (302) having a longitudinal passageway and defining first and second chambers (338, 348). A piston (346) is disposed within the longitudinal passageway between the first and second chambers (338, 348). A valving assembly (356) is disposed within the longitudinal passageway. The valving assembly (356) is operable to selectively prevent communication of pressure from a pressure source of the fluid sampler to the second chamber (348). The valving assembly (356) is actuated responsive to an increase in pressure in the first chamber (338) which longitudinally displaces the piston (346) toward the valving assembly (356) until at least a portion of the piston (346) contacts the valving assembly (356), thereby releasing pressure from the pressure source into the second chamber (348) and longitudinally displacing the piston (346) away from the valving assembly (356).Type: GrantFiled: August 13, 2009Date of Patent: May 31, 2011Assignee: Halliburton Energy Services, Inc.Inventors: Cyrus A. Irani, Vincent P. Zeller, Charles M. MacPhail, Don H. Perkins

Patent number: 7921876Abstract: A rotary control valve and associated actuator control system. An actuator control system comprises a rotary control valve including a generally planar face seal, and an actuator operatively connected to the rotary control valve. Another actuator control system comprises a control valve including multiple faces having multiple ports formed therein. Fluid communication is selectively permitted and prevented between the ports in response to relative displacement between the faces. A differential area is configured to apply a biasing force which maintains sealing engagement between the faces, and which increases in response to an increase in pressure applied to the control valve.Type: GrantFiled: November 28, 2007Date of Patent: April 12, 2011Assignee: Halliburton Energy Services, Inc.Inventors: Adam D. Wright, Vincent P. Zeller

Patent number: 7874206Abstract: A fluid sampler operable for taking at least one fluid sample in a subterranean well and associated methods. A fluid sampling method includes the steps of disposing a fluid sampler at a first target location in the well, receiving the fluid sample into at least a first sample chamber of the fluid sampler, pressurizing the fluid sample in the first sample chamber using a pressure source of the fluid sampler, retrieving the fluid sampler to a surface location, isolating the fluid sample in the first sample chamber from the pressure source of the fluid sampler and supercharging the fluid sample in the first sample chamber using a pressure source on the surface.Type: GrantFiled: December 6, 2007Date of Patent: January 25, 2011Assignee: Halliburton Energy Services, Inc.Inventors: Cyrus A.

Patent number: 7762130Abstract: An apparatus (300) for obtaining a fluid sample in a subterranean well includes a housing (302) having a sample chamber (314) defined therein. The sample chamber (314) is selectively in fluid communication with the exterior of the housing (302) and is operable to receive the fluid sample therefrom. A debris trap piston (318) is slidably disposed within the housing (302). The debris trap piston (318) includes a debris chamber (326). Responsive to the fluid sample entering the sample chamber (314), the debris trap piston (318) receives a first portion of the fluid sample in the debris chamber (326) then displaces relative to the housing (302) to expand the sample chamber (314).Type: GrantFiled: June 13, 2008Date of Patent: July 27, 2010Assignee: Halliburton Energy Services, Inc.Inventors: Cyrus A.
