GEOS provides compositional and black-oil flow simulation capabilities with fully-coupled geomechanics for conventional reservoir management.

Key Capabilities

  • Multiphase flow in heterogeneous formations
  • Compaction and subsidence prediction
  • Fault-seal analysis
  • History matching workflows

Coupled Flow and Geomechanics

The unstructured mesh support and scalable parallel solvers enable detailed field-scale models that capture complex geologic features. GEOS handles the tight coupling between fluid flow and rock deformation that is critical for accurate reservoir management in compacting formations, stress-sensitive reservoirs, and fields with active fault systems.

Production Optimization

GEOS supports compositional flow modeling for enhanced recovery processes. The high-performance computing backend enables ensemble-based workflows for uncertainty quantification and production optimization at field scale.
