Method and apparatus for acoustically measuring the transverse dimensions of a borehole

Patent ·
OSTI ID:5929961
;
This patent describes an apparatus for measuring the transverse dimensions of a borehole, comprising: a sonde adapted for longitudinal displacement through the borehole, the sonde including transducer means for transmitting and detecting diametrically oppositely directed acoustic pulses radially of the sonde, the pulses being directed towards and reflected from opposed wall sections of the borehole, the transducer means including at least one transducer having diametrically opposing active faces substantially parallel to and eccentrically disposed with respect to a longitudinal axis of the sonde.
