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.

Model naturally fractured reservoirs using a hybrid technique combining discrete and implicit fractures.
Visualize observed fracture data as tadpoles and rose diagrams together with other logs and calculate fracture intensity curves.
Use neural networks to combine different fracture drivers. This general trend property then guides the distribution of fractures.
Leverage the Petrel tools to perform a full fracture modeling workflow in an integrated environment.
Tectonic stress domain window for simulation result and comparison to input data and computed fractures.
Computed fracture density property and corresponding geomechanically driven fracture network.
Typical workflow for geomechanically based driver.
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.
