f Model building using 3D tomographic inversion of multi-arrivals - A North Sea case study

Depth imaging requires accurate velocity macro-models in order to produce reliable results. Tomographic inversion has been proven to be a useful tool to derive such models where velocity layers are separated by depth horizons corresponding to the main velocity contrasts. In particular, it can be used in the frame of the layer-stripping methodology (Jones 1993, Diet et al. 1994).
