GEOS provides geomechanical analysis capabilities for wellbore integrity across all subsurface applications.

Key Capabilities

  • Stress analysis around boreholes in complex stress regimes
  • Casing and cement deformation modeling
  • Thermal stress effects during injection and production
  • Completion integrity under reservoir compaction or heave
  • Multi-lateral and deviated well trajectories

Drilling Optimization

GEOS supports mud weight window analysis and borehole stability prediction for complex well trajectories through heterogeneous and anisotropic formations. The coupled poro-thermo-elastic framework captures time-dependent effects that are critical for extended-reach and deep drilling operations.

Long-Term Well Integrity

For injection wells (CO2, hydrogen, geothermal), long-term integrity assessment requires modeling the coupled thermal, chemical, and mechanical loading on casing and cement over decades of operation. GEOS provides the multiphysics framework for these lifecycle analyses.
