Petrel quantitative interpretation

Accurate and comprehensive quantitative interpretation

Petrel™ quantitative interpretation enables true integration of multidisciplinary seismic with well and geological data. This ensures complete description of reservoir properties and extends conventional qualitative interpretation to a quantitative interpretation workflow in the same canvas. Petrel quantitative interpretation is a product development collaboration between SLB and Ikon Science.

Without leaving the Petrel platform, Petrel quantitative interpretation provides seamless seismic data conditioning, rock physics, fluid substitution, AVO/AVA analysis, and pre- and poststack deterministic and stochastic inversion to predict lithology, pore fluid content, and seismic pore pressure modeling.

Rock physics modeling

Explore the comprehensive library of rock models for a wide range of geological settings and expand the library adding custom models. Automatically calibrate model parameters and simulate stochastic rock models to capture heterogeneity and uncertainty. Take advantage of 4d modeling, interacting with geomechanics and dynamic reservoir models.

Rock physics modeling is now included in Petrel quantitative interpretation.

Litho-elastic AVO inversion

Exploit single-loop inversion to elastic properties and lithofacies probability. For improved fracture characterization, experience Orthorhombic AVAZ (amplitude variation with azimuth) inversion; and obtain more accurate results and strong contrasts with non-linear inversion.

Litho-elastic AVO inversion is now included in Petrel quantitative interpretation.

Petrel rock physics and Inversion plug-in provides a set of robust, interactive tools to explore the relationship between seismic amplitudes and reservoir properties in 3D and 4D. Leading-edge seismic AVO inversion techniques enable solving jointly for lithofacies and elastic properties. With petrophysical joint inversion, multiphysics measurement can be integrated for a better estimation of reservoir properties.

This functionality is now included as part of Petrel quantitative interpretation.
