Patent number: 11726224Abstract: A method and apparatus for determining a pressure in an annulus between an inner casing and an outer casing. An acoustic transducer is disposed within the casing at a selected depth within the inner casing and is configured to generate an acoustic pulse and receive a reflection of the acoustic pulse from the inner casing. A time of flight is measured of the acoustic pulse to the inner surface of the inner casing. An inner diameter of the inner casing is determined from the time of flight. The pressure in the annulus is determined from the inner diameter. A processor can be used to measure time and determine inner diameter and annulus pressure.Type: GrantFiled: November 21, 2019Date of Patent: August 15, 2023Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: David Bishop, Carlos Felipe Rivero, James J. Freeman, Roger Steinsiek, Marc Samuelson, Shaela Rahman, Jason Harris

Patent number: 11561318Abstract: Embodiments of the present invention use radar technology to detect features or conditions in a well. A radar unit having an electronics subsystem and an antenna subsystem is positioned downhole in the well. The radar unit is coupled receive power from and communicate with to a surface system. The electronics subsystem generates RF signals which are provided to the antenna subsystem, generating radar wavefronts that are propagated toward areas of interest (e.g., farther downhole). The radar wavefronts may be electronically or mechanically steered in the desired direction. The antenna subsystem receives radar signals that are reflected back to the unit by features or conditions in the well. The received reflected signals are converted to electronic signals that are interpreted by the electronics subsystem of the radar unit or by the surface system to identify the features or conditions that caused the reflections.Type: GrantFiled: March 11, 2020Date of Patent: January 24, 2023Assignee: Baker Hughes Oilfield Operations LLCInventors: Carlos Felipe Rivero, Zhi Yong He

Publication number: 20200408327Abstract: A subsurface valve including a valve body having an inlet, and outlet, and a valve portion. A plunger is shiftably mounted in the valve body to selectively fluidically connect the inlet and the outlet. A valve system is arranged in the valve portion. The valve system includes a fixed member comprising a magnet and a moveable member shiftably mounted in the valve body and mechanically connected to the plunger. A control system is operatively connected to the fixed member. The control system is operable to selectively adjust a magnetic flux of the magnet to shift the moveable member and the plunger.Type: ApplicationFiled: June 26, 2019Publication date: December 31, 2020Applicant: Baker Hughes Oilfield Operations LLCInventors: Zhi Yong He, Carlos Felipe Rivero, Marc Samuelson, Fernando Kirnbauer

Patent number: 10774618Abstract: A downhole power generator module having a body with one or more couplings that are configured to connect the body to a downhole tool string positioned downhole in a wellbore. An axial passageway is formed through the outer housing and couplings. The power generator module has a pressure-driven electric generator such as a triboelectric or piezoelectric generator positioned within the body. A port in the body enables communication of well fluids from the wellbore to the generator. Pressure changes in the well fluids are communicated to the pressure-driven electric generator, causing it to autonomously generate electric power downhole. The generated power is provided directly to other downhole tools without intervention from the surface.Type: GrantFiled: March 16, 2018Date of Patent: September 15, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Yuh Loh, Zhi Yong He, Lily Truong, Felipe Rivero, Zhiyue Xu
