Abstract

The author employs the Kjartansson absorption model to prove that intrinsic dispersion of seismic wave velocities in absorbing media is a basic factor responsible for the differences between elastic rock parameters measured dynamically and statically. Dispersion of Young’s modulus predicted by this model for a frequency range from millihertz to tens of kilohertz matches well the experimental data obtained for polyvinyl chloride plastic used as a test material in the study case.
