Seismic reservoir characterisation is one of the most challenging work for the seismic industry. With progresses in the quality of acquisition and data processing, we are now close to define processing standards for sophisticated studies aiming at solving difficult problems such as reservoir characterisation problems. With the help of appropriate signal processing tools, we can expect to go farther in the analysis of relationships between seismic attributes and reservoir attributes. We want to show in this paper a synthetic case study where non stationary seismic signals have been analysed with the Smoothed Wigner Ville distribution to characterise the fluid content of a real hydrocarbon reservoir.
