GEOS was originally developed with carbon storage as a primary focus and offers mature capabilities for CO2 injection modeling.

Key Capabilities

  • Multiphase CO2-brine flow with dissolution and residual trapping
  • Coupled geomechanics for caprock integrity and deformation monitoring
  • Fault reactivation risk assessment
  • Long-term plume migration prediction
  • Area-of-review assessment
  • Monitoring and verification workflows

Storage Security

GEOS enables coupled flow-geomechanics analysis for assessing multiple trapping mechanisms, caprock integrity under pressure buildup, and fault stability during and after injection. The framework supports the full lifecycle of a storage project from site characterization through post-injection monitoring.

Uncertainty Quantification

The simulator’s HPC capabilities enable uncertainty quantification workflows with large ensembles of high-fidelity models, supporting risk-informed decision making for storage site selection and operational design.
