... Increasing importance is being given to rock dielectric properties as multi-frequency electromagnetic (EM) logging tools continue to be developed in frequency ranges spanning kHz, MHz and even GHz. Applications are varied, from estimating hydrocarbon saturation, carbonates morphology, or rock...

... and to correctly measure formation velocity. By analyzing the acoustic wave phenomena in this environment, we have designated a procedure that incorporates the low-frequency measurement in the 2–4 kHz frequency range. The acoustic compressional waves in this frequency range have a good signal-to-noise ratio...

..., acoustic logging is performed in a very broad frequency range, from 200 Hz up to 35 kHz (Homby et al., 1989; Paillet, 1980). Because the fracture fluid motion excited by logging acoustic waves is dynamic in nature (Johnson et al., 1987; Tang and Cheng, 1988), it is expected that the model that accounts...
