SUMMARY This paper investigates the use of spectral decomposition techniques to detect fluid saturation through studies on field data physical modelling data and numerical modelling. The main mechanisms which control the spectral response are fluid-sensitive tuning together with attenuation and dispersion for reflected waves. In many cases the direct transmission loss
