This month's data example is from the Phase 45 project in the Gulf of Mexico. This is one of the largest 2D surveys in the world with slightly less than 100,000 total kilometers acquired. This survey covers the majority of the deepwater areas of the Gulf of Mexico within the United States borders.
Depositionally speaking this area is dominated with thick and rugose salt structures. Some of them are rooted and some of them free floating with in the section. In order to better explore around and beneath these salt layers TGS-NOPEC has created the "Leviathan Project". This pre-stack depth migration project uses advanced processing techniques combined with the interpretive skills of experienced geoscientist the seismic data is converted to the depth domain and processed to improve the image of the data and better show the potential hydrocarbon sediments associated with tabular salt bodies.
The illustration below shows the time processed version compared with the immensely time intensive depth migrated product. You can see that the sediments below the salt edge have greatly improved and this allows the geoscientist to better explore in these areas.
