Seismic Q estimations for lithological interpretation

In addition to seismic. velocities and densities, quality factor Q estimated from seismic data can help in lithologic interpretations. Q estimations as function of travel time can be used to determine lithology and/or levels of fluid/gas saturation because Q may be an order of magnitude more sensitive to changes in saturation or pore pressure than velocity as it has been shown by Winker and Nur (1979) and Toksoz et al. (1978).
