| Summary: | An experimental method for acquisition offull waveform acoustic logging (FWAL) data
from scaled laboratory borehole/formation models is under development. A spark-gap
source, fabricated in the lab, is used in conjunction with a piezoelectric receiver. It is found that the source/receiver signature covers a suitable frequency range for the 32:1 scaling required by the 6.4 mm model borehole diameter. Waveforms collected from
water-filled boreholes in aluminum and Lucite, simulating fast and slow formations,
clearly exhibit the characteristic arrivals of those formations.
