Velocity Model Building

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
