Patent number: 11920435Abstract: A sub-surface safety valve having a positional flapper, a valve seat, and a remotely actionable opening prong. The opening prong comprising at least one of a debris wiper, filter, and at least one flow hole. The wiper, filter, and at least one flow hole function according to either position or movement of the flapper and opening prong and prevent debris buildup around the valve seat. The wiper is an extendible material in communication with the valve seat and a surface of the opening prong and it extends radially in response to closing the valve. The extension of the wiper in response to closing the flapper cause the wiper to scrape the surface of the valve seat. The filter can comprise a screen integrated with or attached to the opening prong. The flow holes can be in the form of angled flow holes or elongated slots.Type: GrantFiled: May 24, 2019Date of Patent: March 5, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Ross G. Dusterhoft, Bharat B. Pawar, Brad R. Pickle

Patent number: 9816352Abstract: A downhole flow control system utilizes a tubing pressure operated valve to selectively open and close fluid flow across the system. The tubing pressure operated valve includes a piston responsive to tubing pressure, and a valve element responsive to piston movement. The valve element can be moved rotationally, longitudinally, or both, in response to the piston movement. The valve is movable between a closed and at least one open position. The piston and valve elements can be releasably attachable, such as by a one-way ratchet. The valve element can be a rotating valve operable by a J-slot mechanism to rotate to multiple positions in response to movement of the piston element.Type: GrantFiled: March 21, 2013Date of Patent: November 14, 2017Assignee: HALLIBURTON ENERGY SERVICES, INCInventors: Brad R. Pickle, Michael Fripp

Patent number: 9222340Abstract: A flow control assembly can be mechanically adjusted, rotationally or translationally, inside a tubing downhole between multiple positions by an intervening tool from the surface to change resistivity to flow through the flow control assembly. The positions among which the flow control assembly can be adjusted can include a closed position, a fully open position, and positions at which fluid experiences various resistances prior to flowing to an inner area of the tubing.Type: GrantFiled: August 2, 2013Date of Patent: December 29, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Luke W. Holderman, Jean-Marc Lopez, Brad R. Pickle, Frank D. Kalb

Patent number: 8893798Abstract: A housing can be mounted adjacent an isolation valve and after a fixed number of on and off pressure cycles allow a spring to push an actuator to operate the valve to an open position. The actuator, can be reset with a tool run into the module to move the actuator back against a power spring and hold that spring force until the pressure cycling begins again. The preferred application is for a formation isolation ball valve but other valves, such as sliding sleeves, or other types of downhole tools can be actuated with the module that permits a retrofit of a hydraulic operation to a heretofore purely mechanically actuated tool. The actuation force to initially open is boosted by a secondary potential energy source that is unlocked to give an initial boost force to the indexing spring that is part of a j-slot actuation mechanism.Type: GrantFiled: October 6, 2010Date of Patent: November 25, 2014Assignee: Baker Hughes IncorporatedInventors: Steven R. Hayter, Brad R. Pickle, Antonio D. Lazo

Publication number: 20110214854Abstract: Disclosed is a downhole apparatus including a tubular and at least one line passage extending along an outer surface of the tubular. At least one end clamp is located at least one end of the line passage. The at least one end clamp includes a clamp body and at least one standoff located between the clamp body and the outer surface of the tubular defining a clamp protected space therebetween. Further disclosed is a downhole tubular system including a least two tubular apparatus, each tubular apparatus including at least one tubular and at least one line passage extending along an outer surface of the tubular. At least one end clamp is located at least one end of the line passage. The tubular system further includes at least one coupling clamp disposed at a coupling of the at least two tubular apparatus.Type: ApplicationFiled: August 10, 2010Publication date: September 8, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Denise M.

Patent number: 7775283Abstract: A series of screens with restrictors to equalize flow through base pipe perforations downstream or upstream of each restrictor features a valve member in the openings so that the screens are closed to flow for run in. Pressure can be developed within the base pipe for operation of downhole equipment below the screens such as a mud motor or in the screen liner such as a packer with no need for an internal string or wash pipe. The openings can be opened selectively when the associated equipment connected to the base pipes has been operated. The valve member can be actuated to open in a variety of ways such as applied pressure, temperature or a change in well fluid condition.Type: GrantFiled: November 13, 2006Date of Patent: August 17, 2010Assignee: Baker Hughes IncorporatedInventors: Martin P. Coronado, Brad R. Pickle
