Analyze any stress regime
DSA uses either a user-defined uniform stress field or a 3D tensorial in-situ stress field calculated by the VISAGE simulator.
New stability plots in the Petrel platform
Stability of fault surfaces and fracture sets are analyzed directly in the Petrel platform. This provides an easy tool for geologists and engineers to address questions of stimulation and fault reactivation.
Identify critical fault dips and azimuths
For a given tectonic regime, critical dip angles and azimuths are plotted using a customized Mohr-Coulomb diagram and stereonet chart.
Visualize critically stress fractures
Critically stressed fractures play an important role in further analysis, such as planning hydraulic stimulation.

Overview
An extension of Petrel Geomechanics, DSA provides a simple process to analyze and visualize the stability of faults and fracture patches in the Petrel platform. Analysis of the local tectonic stress state and Mohr-Coulomb shear failure are displayed via a stability diagram or 3D window, providing valuable insight for fracture characterization and fault stability studies.
Specifications
Stability analysis of fault surfaces and fracture networks
Tool for plotting Mohr-Coulomb and steronet stability diagrams
Identify critical stressfractures and calculate critical pore pressure
Index filtering within an area of interest
Quick specification of custom tectonic stress states
Trends and spatially varying stress input
Integrates with Petrel Reservor Geomechanics and VISAGE simulations
Features
With the ability to analyze discrete fracture networks as well as Petrel platform surfaces, the plug-in provides a flexible tool for geomechanical analysis. Complex stress fields, including lateral variations and stress rotations can be accounted for through the integration with the Petrel Reservoir Geomechanics workflow. An index filter allows choosing a sector model for the analysis.
