Overview

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.

4D rock physics modeling of the elastic response of production-induced changes in the reservoir and overburden is conducted with interaction with flow simulation and geomechanical models.

Applications

Rock physics modeling
Litho-elastic AVO inversion
Petrophysical inversion

Benefits
