C017 MAKING DENSE VELOCITY FIELDS THE NORM Abstract 1 Since 2000 we have been working to deliver routine high-density velocity analysis for production processing. This involves initially manually picking a 500 metre grid velocity field followed by autopicking on a 50 metre grid. The velocities are carefully edited filtered and QC’d with several new methods. We now perform dense automated velocity picking routinely for all marine surveys in the time-domain and we are increasingly using the approach for depth-imaging projects. Further improvements to the velocities will be delivered by the use of bi-spectral picking as well as geostatistical filtering techniques.
