Patent number: 11719090Abstract: Methods and apparatus for inspecting oilfield infrastructure components. Methods include methods of identifying a micro-annulus outside a casing in a cemented wellbore. Methods may include transmitting an acoustic pulse incident on the casing; making a measurement of a first acoustic impedance property value from pulse-echo information generated responsive to an echo of the acoustic pulse reflected from the casing; propagating a circumferential guided wave in the casing; making a measurement of a second acoustic impedance property value from propagating wave information generated responsive to the propagating acoustic wave; and determining from the first acoustic impedance value and the second acoustic impedance value a presence of a micro-annulus between the casing and the cement.Type: GrantFiled: March 18, 2020Date of Patent: August 8, 2023Assignee: Baker Hughes Oilfield Operations LLCInventors: Pawel J. Matuszyk, Douglas J. Patterson

Patent number: 11378708Abstract: Methods, systems, and devices for downhole evaluation using a sensor assembly that includes a sensor plate, wherein a surface of the sensor plate forms a portion of a surface of a downhole tool. Methods include bringing the surface of the sensor plate into contact with downhole fluid; generating a guided wave that propagates in the sensor plate by activating the sensor assembly at at least one frequency configured to excite both a symmetric mode and an anti-symmetric mode; making at least one first attenuation measurement of the symmetric mode of the guided wave; making at least one second attenuation measurement of the anti-symmetric mode of the guided wave; and using the at least one first attenuation measurement and the at least one second attenuation measurement to estimate at least one parameter of interest of the fluid. Methods may include submerging the surface of the sensor plate in a downhole fluid.Type: GrantFiled: December 20, 2018Date of Patent: July 5, 2022Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Xiaochu Yao, Douglas J.

Patent number: 11066920Abstract: Methods and apparatus for inspecting oilfield infrastructure components. Methods include estimating an optimal value for at least one excitation parameter for an acoustic excitation source to produce a guided wave of mixed multiple modes in the component; selecting at least one excitation parameter corresponding to an optimal simulated guided wave determined in dependence upon the application of waveform criteria to the time domain waveforms; and generating a guided wave in the tubular using the at least one optimal excitation parameter. Methods may include calculating a guided wave dispersion relation; modeling each of the plurality of simulated guided waves, wherein the modeling comprises generating a time domain waveform for each of a plurality of wave modes in dependence upon the acoustic excitation source; selecting the at least one excitation parameter corresponding to an optimal simulated guided wave determined in dependence upon the application of waveform criteria to the time domain waveforms.Type: GrantFiled: November 10, 2017Date of Patent: July 20, 2021Assignee: BAKER HUGHES HOLDINGS LLCInventors: Xiaochu Yao, Pawel J.

Patent number: 10436018Abstract: Systems, devices, and methods for estimating a value of a downhole parameter of interest. Aspects include an apparatus for evaluating a tubular. The apparatus may include a sensor including an electromagnetic acoustic transducer (EMAT) device configured to be conveyed into the tubular. The EMAT device may include measurement circuitry comprising at least one conductive coil; and a magnet array comprising magnets arranged with a corresponding direction of magnetization of each magnet oriented according to a configuration producing a greater magnetic flux on a first side of the array than on a second side opposing the first side. The magnetic flux produced from the second side may be substantially zero. In embodiments, the configuration of magnets comprises at least a first set of permanent magnets in a linear Halbach configuration.Type: GrantFiled: October 7, 2016Date of Patent: October 8, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Babak Kouchmeshky, Xiaochu Yao, Stanislav Forgang, Pawel J.
