  1. Using 3D Prestack Depth Migration to take a new look at a mature area Authors Fiona Dewey Wintershall Noordzee B.V. Malcolm King Monarch Technical Services Phil Whitfield Western Geophysical

  2. Outline • Regional setting • Imaging problems • Velocity model building methodology • Results • Conclusions

  3. Buntsandstein Rotliegend Time Migration 5 km Complex Geology  Poor Imaging

  4. Final Velocity Model 40 km

  5. Conclusion Structurally complex areas require detailed velocity models - use multiple model building tools - check model changes on gathers & stacks - close cooperation between processors, interpreters and researchers - 90% solution rather than 70% result Optimal image quality  Reliable structural picture
