  • Patent number: 5146050
    Abstract: Apparatus is provided for acoustically logging earth formations surrounding a borehole containing a known fluid, and includes a downhole tool adapted for longitudinal movement through the borehole, an acoustic transducer assembly for transmitting and receiving acoustic pulse energy, and extendable arms mounting the acoustic transducer assembly on the tool and adapted for lateral extension therefrom for positioning the acoustic transducer assembly in contact with the borehole wall. The acoustic transducer assembly further includes acoustic transducer means for generating acoustic pulse energy for coupling into the borehole fluid substantially free of acoustic ringing and directed an axis generally normal to the borehole wall surface.

  • Patent number: 4834209
    Abstract: A transverse-wave logging tool consists of a plurality of sets of transducers mounted around a cylindrical mandrel. The transducer active faces are characterized by two orthogonal dimensions, one of which dimensions is a half-wavelength long relative to the acoustic excitation energy applied to a transmitter transducer and the transverse-wave formation velocity. Receiver transducers detect converted-compressional waves resulting from transverse waves that were generated by the acoustic excitation energy.

  • Patent number: 4809237
    Abstract: A method for monitoring the relative goodness of a cement bond to a borehole casing by observing the relative change in amplitude of a converted-compressional wave as a function of depth in the borehole.
