Overview

Petrel™ fracture modeling provides full flexibility for both stochastic and geomechanical fracture characterization using either stochastic or deterministic methods. Fractures can be modeled as either discrete or implicit fractures or as a combination of both. Additionally, a geomechanics-based 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 makes it possible to extract geometrical characteristics of potential natural fractures developed inside the perturbed stress field. Calibration is applied with observed fractures along wells to provide a calibrated computed density of the fractures.

Applications

Computed fracture density property
Create grids with strike directions
Calculate fracture intensity curves

Benefits

Fracture models can be distributed and upscaled to 3D grids for simulation where advanced permeability upscaling options are available, including Oda and flow-based methods. The Petrel fracture modeling workflow enables full integration with the Eclipse industry-reference reservoir simulator and Intersect high-resolution reservoir simulator using multiple porosity models for advanced simulation of naturally fractured reservoirs.
