Velocity Model Building is an essential component for accurate depth imaging. Z-Terra has a wide range of velocity model building algorithms and workflows that provide high resolution depth anisotropic velocity models:
- Vertical and normal ray updates
- Deregowski loop updates
- Wide azimuth tomography using offset gathers produced by Kirchhoff or Fast Beam Migration (FBM)
- Wide azimuth tomography using angle or extended gathers produced by Kirchhoff, Fast Beam, or wave-equation migration
- Residual move-out gather-flattening and gather-fitting techniques
