Velocity Dispersion and the Petrophysical Properties of Porous Media

Seismic attenuation and velocity dispersion depend on the petrophysical properties of porous media. Using broadband uncorrelated vibrator VSP data, we measure velocity dispersion in the exploration seismic frequency band with satisfactory accuracy. Then, velocity dispersion data are fitted to petrophysical models. This approach provides new insights into the linkage between velocity dispersion and physical rock properties of porous or fractured media.
