Popis:	There are a wide variety of approaches to building velocity models with prestack depth migration. The most common pitfalls we see in them are extracting reliable yet detailed information about velocity errors from migrated data and then the inability to produce geologically reasonable velocity models from these error estimates. We extract detailed error estimates along horizons from finely sampled migrated data, edit them statistically, and QC the edits in map view. Tomography converts these error estimates into new velocity models or velocity model updates using a flexible model building system.
