....In the first part of our example we will concentrate on improving the focusing of the image. To achieve an enhanced focusing, we used Stolt residual migration in the prestack domain (Stolt , 1996; Sava , 1999) Another alternative to obtain a better focusing would be to use velocity continuation (Fomel , 1997). The dataset is part of a gashydrate study, and was recorded at the Blake Outer Ridge, offshore Florida and Georgia (Ecker , 1998) Figure (2) shows the image obtained with a starting velocity model, while Figure (3) shows an image obtained by applying residual migration to the original. The ....
