Make optimal decisions and accurately assess risks

Subsurface stresses and rock deformations and failure have potential to adversely impact exploration activities, field development, and production operations. To make optimal decisions throughout the life of the field and accurately assess risks, engineers and geoscientists must consider—from the outset—the geomechanical behavior of their reservoirs and the surrounding formations.

Petrel Reservoir Geomechanics software provides an integrated and efficient environment for 3D preproduction geomechanics modeling or for 4D geomechanics modeling of fields under operation. The powerful VISAGE finite-element geomechanics simulator is combined seamlessly with other interpretation and modeling workflows within the Petrel E&P software platform.

This allows geomechanics experts and non-experts alike to incorporate geomechanical analyses into their reservoir or structural models, or to create new subsurface models for geomechanics simulation.

Reduce nonproductive time

During exploration work and in early field life, 3D preproduction geomechanics modeling enables companies to assess potential for drilling risks, reduce nonproductive time, and avoid unexpected problems or increased well costs.

Assess formation compaction and overburden movements

When coupled to a reservoir simulation to incorporate time, 4D models allow operators to predict stress changes, deformation, or rock failure that might occur later in the life of their field. This allows geoscientists and engineers to assess formation compaction and overburden movements that may impact on well/completion survivability, potential for solids production, inadvertent loss of reservoir containment and out-of-zone injection, changes in reservoir characteristics and performance, and risk of induced rock failure and seismicity from fracturing or fault activation. The same models can also be used to help optimize recovery schemes and stimulation:

Assessment and mitigation of geomechanics risks can also be performed, from exploration to production:

• Complex environments, including salt and subsalt
• Exploration and preproduction phases
• Fields under development or in operation
• Drilling, well construction, and well survivability
• Underground gas storage, CO2 disposal and EOR, gas and water injection, and waste disposal
• Improved stimulation design and optimization
• Reservoir, fault, and cap-rock integrity studies
• Geomechanics effects in 4D seismic
• Prediction of overburden movements and potential environmental impact
• Honoring of complex geological or reservoir models
