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.

Rock physics modeling

  • Comprehensive library of rock models for a wide range of geological settings
  • Library expansion by adding custom models
  • Automatic calibration of model parameters
  • Stochastic rock model simulation to capture heterogeneity and uncertainty
  • 4D modeling, interacting with geomechanics and dynamic reservoir models

Litho-elastic AVO inversion

  • Single-loop inversion to elastic properties and lithofacies probability
  • No requirement for explicit definition of the low-frequency model (LFM)
  • Nonlinear inversion for more accurate results around strong contrasts
  • Orthorhombic amplitude variation with azimuth (AVAZ) inversion for improved fracture characterization

Petrophysical inversion

  • Joint estimation of petrophysical properties and associated uncertainty
  • Integration with multiphysics data
  • Options for deterministic and probabilistic methods
