A strong 4D difference is expected at the Gas-Oil contact at 3400 m depth due to the large velocity variation as indicated in the Figures 4b and 4c. Figure 4: a) Design of non-repeated OBN geometries. b) Section of the SEAM 4D pilot velocity model. c) Depth slice at the top reservoir (3400 m) of the 4D velocity variation. all 4d
