VISAGE Finite-Element Geomechanics Simulator

Understand geomechanical risks and optimize production.

Industry-leading reservoir geomechanics simulator

The VISAGE finite-element geomechanics simulator enables you to plan for and mitigate risks by modeling problems before they occur. This includes the following:

  • Compaction and subsidence
  • Well and completion integrity
  • Cap-rock and fault-seal integrity
  • Fracture behaviour
  • Thermal recovery
  • CO2 disposal

The industry-leading VISAGE simulator has over 20 years’ pedigree and benefits from continuous software development and innovation.

Seamless end-to-end workflow

The Petrel E&P software platform combines transparent data flows with an easy-to-learn graphical user interface that supports the VISAGE simulation configuration and results visualization. The powerful functionality of the VISAGE simulator is combined seamlessly with other interpretation, modeling, and engineering workflows within the Petrel platform.

With the Petrel-enabled workflow, you can include multiple data types to create new 3D geomechanics property and stress models, or add geomechanics data to augment existing reservoir subsurface models. This seamless combination within the Petrel platform ensures that the geomechanics model is consistent and integrated with geophysics, geology, petrophysics, and reservoir data.

Powerful numerical simulations

The initial structural and properties model, created using Petrel Reservoir Geomechanics, is submitted to the VISAGE numerical simulator, and controlled from within the same familiar Petrel environment. 

The VISAGE simulator can also be coupled to the ECLIPSE industry-reference reservoir simulator for both one-way and two-way coupling. In one-way coupling, the ECLIPSE simulator models the flow of fluids in the reservoir and calculates the pressure, temperature, and saturation changes that result.

The VISAGE simulator uses these calculations  to perform 3D static or 4D flow-, pressure-, and temperature-coupled calculations for rock stresses, deformations, and failure. Two-way coupling between the ECLIPSE and VISAGE simulators allows permeability updating of the reservoir model at any selected time-steps, as well as updating of mechanical properties in the geomechanics model to account for effects such as changing saturations and water softening.

For large models (many millions of cells), or those coupled to ECLIPSE reservoir simulation, users are also able to perform parallel geomechanics simulation runs using local or remote clusters. The entire process—for single machines or multicore clusters—is managed by the Petrel platform, permitting the same seamless workflow to be maintained from project start to end.  

Complex and highly heterogeneous models

The VISAGE simulator is able to model hundreds of faults, hundreds of thousands of discrete fractures, and highly heterogeneous models, meaning that the same high-degree complexity that exists in the geological model can be maintained throughout the geomechanics analyses.  

Reservoir geomechanics across field lifecycle

The VISAGE simulator provides powerful 3D and 4D geomechanics simulation across the entire field lifecycle.  This allows geoscientists and engineers to assess and mitigate potential geomechanics problems affecting well and completions, stimulation, production, injection, and field management.
