Samenvatting

Frequency-dependent guided wave modes along boreholes in porous formations are studied experimentally. A shock tube technique is applied to measure phase velocities and attenuation coefficients for natural (Berea sandstone) and synthetic porous materials. Quantitative agreement between the experimental results and theoretical predictions based on Biot theory is found for the phase velocity in the frequency range from 1 to 50 kHz. The results in the frequency domain indicate that we are able to excite multiple guided waves in different band of frequencies in the synthetic formation. For the Berea sandstone, a very good resolution of the pseudo-Stoneley wave is achieved at both the time and frequency domain.
