Abstract
Average models of the medium are normally used to describe the phenomena of seismic wave scattering and absorption, although the underlying physical processes are related to small-scale properties of the rock. Corresponding theories establish the relations between seismic wave amplitude and attenuation coefficients as smooth functions of the frequency and medium parameters. We discuss a seismic resonance phenomena in porous media. We show that the attenuation of seismic energy in a porous medium may be quite different within a short frequency interval. We examine the possibility of using the attenuation of seismic resonance frequencies for the interpretation of seismic data.
