Paper Summary
We outline the evolution of a velocity model building workflow incorporating Dynamic Matching Full Waveform Inversion and multi-azimuth tomography for dense, long offset Ocean Bottom Node data in the Norwegian North Sea and evaluate the improvements this high-resolution velocity model brings to the final migrated image. Event positioning, reflector continuity and image resolution are all enhanced when compared to legacy processing and the model itself can now be considered an interpretable final product as we push towards higher frequencies.
