Extracting frequency dependent velocities from full waveform sonic data
Abstract
In porous, fluid-filled rock formations, compressional seismic wave velocities show a strong dependence on frequency. The potential linkage between P-wave velocity dispersion and permeability would make the use of broadband sonic waveform data suitable for determining reservoir parameters. Automatic velocity analysis of multi-channel sonic data can be tailored to detect and measure frequency dependent velocities.This seismic data processing strategy enables the creation of velocity dispersion logs for fluid-filled porous media.
