ABSTRACT 1 With improvements in acquisition and processing techniques new seismic data are now available for the geoscientist for seismic reservoir characterization: PP and PS cubes in prestack domain and also prestack inverted impedance cubes. In all these cubes fluid content saturation and porosity can have a major impact on the seismic response but layer thickness can also alter significantly the seismic signal due to tuning. We propose
