Abstract

Despite obvious benefit of using the attenuation as additional petrophysical parameter it still not widely used. The problem is the difficulty of measurement from fullwave sonic. We propose a modification of the spectral relations method basing on reciprocity principle. Synthetic tests demonstrate a significant improvement of accuracy and reliability of estimates. Real data processing showed that P-wave attenuation is very small in acoustic frequency range and is not a diagnostic parameter. S-wave attenuation waves increases sharply in interval of gas- and oil-saturated reservoir and can be used for joint logs interpretation.
