f Analysis of seismic resonance phenomena in porous sediments

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.
