Abstract Seismic data are inherently non-unique and reservoir characterization based on seismic amplitudes relies on realistic a priori geologic constraints. One of the key issues in seismic data analysis is to understand the expected response of brine saturated sands versus shales (i.e. the background trend) at any given depth before we can
