The Petrel Rock Physics and Inversion plug-in provides a set of robust, interactive tools for quantitative interpretation. Its advanced rock physics modeling capabilities enables you to explore the relationship between seismic amplitudes and reservoir properties. The plug-in features leading-edge seismic AVO inversion techniques that solve jointly for lithofacies and elastic properties, reducing the reliance on prior models. Petrophysical joint inversion can be performed to integrate multiphysics measurements for a better estimation of reservoir properties.
