Petrel Fracture Modeling

Petrel Fracture Modeling offers full flexibility for both stochastic and geomechanical fracture characterization, utilizing either stochastic or deterministic methods. Fractures can be modeled as either discrete or implicit fractures or a combination of both. Additionally, a geomechanics method models the perturbed stress field directly linked to the active faults, under applied tectonic stresses. The tectonic stresses through geological time can be obtained from an inversion using the fracture data and the fault model or, alternatively, can be imposed directly. This allows the possibility to extract geometrical characteristics of potential natural fractures developed inside this perturbed stress field. Calibration is applied with observed fractures along wells, providing a calibrated computed density of the fractures.

Fracture models can be distributed and upscaled to 3D grids for simulation, where advanced permeability options are available including Oda and flow-based methods. The Petrel Fracture Modeling workflow allows full integration with the ECLIPSE reservoir simulator and INTERSECT high-resolution reservoir simulator using multiple porosity models for advanced simulation of naturally fractured reservoirs.
