Paper Summary

It is widely accepted that the key to successful sub-basalt imaging in the Atlantic Margin region is to generate as much low frequency energy as possible. Whilst recent acquisition in the Faroe-Shetland Basin (FSB) has seen the towing of sources and streamers at increasing depth to concentrate more energy into the low end of the amplitude spectrum, a large volume of data exists with a more conventional and shallower towed configuration such as TGS s FSB 1999 and 2000 surveys. Through the reprocessing of these datasets we demonstrate that a significant improvement can be made to image potentially prospective Mesozoic and Palaeozoic sub-basalt structures. This is achieved without compromising the relatively high resolution of the overlying Tertiary section.
