  • Televiewer image wood-grain reduction techniques
    Patent number: 8913461
    Abstract: Measurements made by a transducer assembly for downhole imaging are affected by reverberations between the transducer and the window on the outside of the assembly. The reverberations result in a stationary noise on the image. Hardware solutions to improve signal-to-noise ratio includes using a composite transducer, adjusting the distance between the transducer and the window. SNR can also be improved by processing techniques that include stacking, fitting a sinusoid to the reverberation, by envelope peak detection, and by applying a notch filter.
    Type: Grant
    Filed: December 17, 2013
    Date of Patent: December 16, 2014
    Assignee: Baker Hughes Incorporated
    Inventors: Roger R. Steinsiek, Jason M. Harris, Jinsong Zhao, Douglas J. Patterson, James B. Domnanish
