A pre-stack simultaneous inversion over the Mid-Jurassic interval in the Cooper-Eromanga Basin, South Australia produced very good predictions of elastic properties (correlations >80%) for acoustic impedance (AI), shear impedance (SI) and density (Rho). Direct and accurate estimation of density from seismic AVO is expected to be difficult for many reasons. However, the correlation of density in this case is surprisingly higher than the other elastic properties. This webinar reveals how a good density prediction is achieved and whether it can be trusted.
