Migration velocity model

The migration velocity model (provided by Norsk Hydro), shows a large, complex salt body with steeply dipping flanks in both inline and cross-line directions (Figure 5). The water-bottom itself dips in some places as much as 11 degrees in the cross-line direction, although it is relatively flat in the inline direction.
