Patent number: 11773686Abstract: An apparatus includes a sub-surface safety valve (SSSV) to be positioned in a wellbore. The SSSV is configurable to move between a closed position and an open position. While in the closed position, the SSSV prevents downhole fluid in the wellbore to flow to a surface of the wellbore. While in the open position, the SSSV allows the downhole fluid in the wellbore to flow to the surface of the wellbore. The apparatus further includes an electrostatic motor to be positioned in the wellbore and to be coupled to the SSSV. The electrostatic motor is to be selectively powered to move the SSSV between the closed position and the open position.Type: GrantFiled: April 21, 2021Date of Patent: October 3, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Gregory Thomas Werkheiser, Michael Linley Fripp, Xiaoguang Allan Zhong

Patent number: 11634983Abstract: Systems and methods for wireless telemetry in oil and gas wells use fluid pressure differentials to send signals from surface equipment to a downhole tool. More specifically, the methods and systems selectively apply fluid pressure to a tubing string and measure the resulting mechanical strain, or deformation, on a tubular of the downhole tool. The deformation may be an elastic deformation or it may be a plastic deformation with yielding of the tubular. One or more of such strains or deformations may be used to encode a digital signal that can command an action on the tool. The strain or deformation may be measured by a low-cost strain gauge.Type: GrantFiled: May 28, 2020Date of Patent: April 25, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Gregory Thomas Werkheiser, Michael Linely Fripp, Zachary William Walton

Patent number: 11608712Abstract: An electrically-controlled, pin-pulling valve includes a pull pin (e.g., a pull piston) and a chemical propellant. The valve is configured to, using the pull pin and the chemical propellant, actuate from a closed position to an open position to activate a downhole tool. For instance, the pin-pulling valve may, based on an activation signal, activate the chemical propellant, which may cause the chemical propellant to react. The activation of the chemical propellant may cause the pull pin to withdraw from an extended position to a withdrawn position. The withdrawal of the pull pin may cause the pin-pulling valve to open, allowing hydraulic fluids to flow through a port associated with the downhole tool previously sealed by the pin-pulling valve. The flow of the hydraulic fluids may activate the downhole tool by exerting hydraulic pressure on the downhole tool.Type: GrantFiled: December 23, 2020Date of Patent: March 21, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Gregory Thomas Werkheiser, Michael Linley Fripp, Zachary William Walton
