Abstract
Comparison of SCF values between wells in shallow and deep water, from a large database of values from Norway and Australia, shows that delta anisortopy must depend primarily on seismic wave propagation angle. The principle for modelling delta should be to use MSL parallell layers, and not seabed parallell. This is different from what many workers do. The large database at hand for our study makes this a firm conclusion.
