  • Casing thickness evaluation method
    Patent number: 8061206
    Abstract: Evaluating casing thickness by inducing SH0 and SH1 modes of a shear wave in the casing. The SH0 group velocity and SH1 mode group velocity (Vg) are measured and the measured SH0 mode group velocity is assigned as the tubular material shear velocity (Vs). A shear wave wavelength ? from the ratio of SH0 mode frequency (fo) and the measured SH0 group velocity is estimated. The tubular thickness (d) is estimated from the estimated shear wave wavelength ?. The transmitter can be calibrated to operate at an optimum frequency.
    Type: Grant

  • Micro-Annulus Detection Using Lamb Waves
    Publication number: 20090231954
    Abstract: A method, apparatus and computer-readable medium for identifying a micro-annulus outside a casing in a cemented wellbore. The attenuation of a Lamb wave and a compressional wave is used to determine a presence of a micro-annulus between the casing and the cement.
