Publication number: 20200278466Abstract: Methods and systems for displaying sonic logging data are described herein. The displayed data includes highly reliable quality control (QC) indicators that can be used to identify any need for a dispersion correction. The disclosed data-driven approach determines whether a dispersion curve is asymptotic to the true formation shear slowness by calculating a coherence of the slowness at frequency intervals of the dispersion curve to indicate the level of the velocity dispersion. This coherence indicator can then be plotted against the averaged slowness within the frequency interval to show how well the asymptotic slowness is approached. The coherence indicator can be projected onto a slowness log as a QC indicator. A calculated formation shear slowness can be overlaid upon the slowness log.Type: ApplicationFiled: May 1, 2019Publication date: September 3, 2020Inventor: Yibing Zheng

Patent number: 10598563Abstract: A method for operation of an acoustic tool, having a plurality of acoustic sensors, may include receiving acoustic waves from an acoustic source located at a depth in a borehole. A selected location (e.g., central location) of the acoustic sensor array may be positioned substantially at the depth of the acoustic source based on a symmetricity of an upper and lower section of a frequency-wavenumber (f-k) transform pattern with respect to a selected wavenumber. A radial distance from the acoustic source to the acoustic tool may be determined based on a theoretical f-k transform pattern used as a mask to filter measured data in the f-k domain.Type: GrantFiled: September 7, 2016Date of Patent: March 24, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Yinghui Lu, Chung Chang, Mark V.

Patent number: 10365389Abstract: In accordance with embodiments of the present disclosure, systems and methods for taking acoustic/ultrasonic wave measurements of a wellbore using a downhole tool equipped with microelectromechanical (MEM) transducers are provided. The MEM transducers may include a plurality of MEM transmitters (e.g., MEM speakers) and a plurality of separate MEM receivers (e.g., MEM microphones). These MEM transducers may be disposed in arrays proximate an outer surface of the downhole tool to collect acoustic/ultrasonic wave measurements of the full circumference of a wellbore. Due to their small size, large numbers of MEM transducers may be distributed radially around the downhole tool. Such an arrangement of sensors may enable the downhole tool to perform measurements of the entire wellbore without the downhole tool needing to be rotated, leading to an increased signal-to-noise ratio of the measurements.Type: GrantFiled: November 17, 2015Date of Patent: July 30, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Tatiana Gilstrap, Yinghui Lu, John P.

The method and system select a geometric shape from a plurality of geometric shapes to fit to the data points based on the point-to-point angles, the plurality of geometric shapes including a circle and an ellipse. A shape of the borehole is estimated at a location of the standoff measurement based on the selected geometric shape.Type: GrantFiled: August 24, 2016Date of Patent: June 25, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Yibing Zheng, Taher Kortam, Clint K.

Patent number: 10301932Abstract: Systems, methods, and software for determining impedance of a casing-cement bond are described. In some aspects, the bond impedance is determined based on results of comparing a measured waveform and a model waveform. The model waveform corresponds to an estimated impedance of the bond and corresponds to a ray tracing of an acoustic signal that accounts for a radiation pattern of the acoustic transmitter and a curvature of the well casing. The measured waveform and the model waveform are generated based on operating an acoustic transmitter and an acoustic receiver within a wellbore comprising the well casing.Type: GrantFiled: July 15, 2014Date of Patent: May 28, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Tianrun Chen, Yibing Zheng, Tatiana Gilstrap, Arthur Chuen Hon Cheng, Robert Eric Epstein, Zhijuan Zhang
