Abstract

Summary

Data acquired in shallow water environments often exhibit a strong acquisition pattern relating to variations in incidence angle, azimuth and source signature from inner to outer streamers. These variations must be accurately compensated for during processing to reveal a spatially consistent 3D image of the data. With modern broadband acquisition this problem becomes more challenging as the frequency spectrum is wider. This North Sea case study, acquired with a multi-level source and variable depth streamer, presents an enhanced processing sequence containing 3D processing steps using different parameters for each frequency range. Results show the advantage of such a sequence to achieve a high definition image from the very shallow to the deep reservoir target.
