Gocad Research Topics

Construction of geological surfaces from subsurface data:
- points (seismic picks, well picks)
- lines (seismic picks, cross-sections, geological maps)
- potential fields (3D distance functions and other scalar property fields)
- orientation data (field measurements, wellbore imaging)
- Fast model building and updating from sparse field and remote sensing data
Modeling geological structures with surfaces:
- Fault network modeling
- Horizon/Fault contacts modeling
- Real-time model updating under geological constraints
Modeling of geological volumes:
- Creation of conforming Geo-cellular models
- Boundary Representations
- Model updating and re-meshing under geological constraints
- Volume visualization
