Popis: We present an integrated approach combining Full-Waveform Inversion and rock physics inversion to estimate CO2 saturation at Sleipner. Acoustic FWI provides high-resolution P-wave velocity images where the uncertainty is quantified using posterior covariance matrix analysis. The seismic properties and their associated uncertainties are used as input to the rock physics inversion. At the fairly large distance of the injection point (533m), we derive CO2 saturations lower than 30% and which are following a patchy mixing distribution.
