Patent number: 11753905Abstract: A flow tube is axially moveable within an actuator body between a first axial position and a second axial position for actuating a downhole tool, such as for closing a subsurface safety valve. The flow tube includes an interior flow bore for conveying fluids from the tubing string through the actuator body. An external flow tube profile defined on the flow tube includes an upper shoulder for engagement with a wiper in the first axial position, a lower shoulder for engagement with the wiper in the second axial position, and a clearance path between the upper and lower shoulders for allowing viscous flow past the wiper when the flow tube is moved between the first and second axial positions.Type: GrantFiled: March 29, 2021Date of Patent: September 12, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Ross Glen Dusterhoft, Brad Richard Pickle, Leo Guadalupe Collins, Adam Evan Beck, Matthew Lawrence Apiecionek, Michael Wade Meaders

Patent number: 11661826Abstract: A flow control system for a well includes a primary safety valve and a secondary safety valve disposable within a valve body of the primary safety valve. The secondary safety valve may include a control line port for receiving control fluid pressure from the same control line as the primary safety valve. A choke in fluid communication with the control line port delays a closing of the secondary safety valve relative to a closing of the primary safety valve in response to a decrease in the control fluid pressure.Type: GrantFiled: April 28, 2021Date of Patent: May 30, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Ross Glen Dusterhoft, Brad Richard Pickle, Charles David McFate

Publication number: 20220349279Abstract: A flow control system for a well includes a primary safety valve and a secondary safety valve for controlling flow from production tubing in the well. The primary safety valve includes a first valve body, a first flapper, a first control line port for receiving control fluid pressure from a control line, and a first actuator operable to open the first flapper in response to the control fluid pressure. The secondary safety valve is disposable within the valve body of the primary safety valve. The secondary safety valve also includes a second valve body, a second flapper, a second control line port for receiving control fluid pressure from the same control line as the primary safety valve when the secondary safety valve is disposed in the first valve body of the primary safety valve, and an actuator operable to open the second flapper in response to the control fluid pressure.Type: ApplicationFiled: April 28, 2021Publication date: November 3, 2022Applicant: Halliburton Energy Services, Inc.Inventors: Ross Glen Dusterhoft, Brad Richard Pickle, Charles David McFate

Patent number: 10597973Abstract: A method of hydraulically actuating downhole equipment includes supplying pressure P(z) to a downhole network comprising tools T(n), tool T(x), control lines C(z), and control lines Y(z), wherein n and z are integers, and x=n+1, wherein a pressure P(z) is applied to tool T(n) using at least one control line C(z) in hydraulic communication with tool T(n); applying pressure P(z) to a hydraulically movable portion of tool T(n), wherein pressure P(z) to tool T(n) is not high enough to independently activate tool T(x); and applying each pressure P(z) to a hydraulically movable portion of tool T(x), wherein tool T(x) is only activated when all of pressures P(z) are simultaneously applied to the hydraulically movable portion of tool T(x), and wherein tool T(x) is only activated when each pressure P(z) is at least at a preset value PV(z).Type: GrantFiled: December 8, 2016Date of Patent: March 24, 2020Assignee: Halliburton Energy Services, Inc.Inventor: Brad Richard Pickle

Patent number: 9080421Abstract: 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 7, 2012Date of Patent: July 14, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Luke William Holderman, Jean-Marc Lopez, Brad Richard Pickle, Frank David Kalb
