20140177389 | Use of Lamb and SH Attenuations to Estimate Cement Vp and Vs in Cased Borehole - A method of determining properties of a bonding material disposed outside of a casing in a borehole includes at least two of the following three pairs of operations: (1) inducing an acoustic wave in the casing, and measuring attenuation of the acoustic wave, by pulse-echo or other cement bond logging measurement; (2) inducing an SH wave in the casing, and measuring attenuation of the SH wave; and (3) inducing a Lamb wave in the casing, and measuring attenuation of the Lamb wave. (2) and/or (3) may be performed by an electromagnetic acoustic transducer. The method further includes determining the shear velocity or shear impedance and the compressional velocity or compressional impedance of the bonding material based on appropriate ones of the measurements. The bonding material may be cement. | 06-26-2014 |

20090231954 | Micro-Annulus Detection Using Lamb Waves - 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. | 09-17-2009 |
20100263449 | Casing Thickness Evaluation Method - 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 λ from the ratio of SH0 mode frequency (f | 10-21-2010 |

20110082405 | Device for treating hallux varus - A device for straightening a toe which has deviated away from the midline of the foot comprising an assembly for retaining the toe, a tension mechanism and an assembly for securely positioning the foot in said device and such as when pressure is applied to the toe the toe can be returned to its normal position. The tension mechanism is one which is able to produce a graded amount of tension. | 04-07-2011 |
