Reverse time migration (RTM) is now recognized as a powerful imaging tool. With its ability to account for rapid spatial variations in the velocity model and to utilize all wavefront information, RTM can produce superior images of the most complex structures. This is why RTM is frequently used to interpret salt structures in regions known to have complex salt geometries like the Gulf of Mexico. With the application of recent advancements such as Vector Offset Output and 3D angle gathers, the imaging capability of RTM is enhanced even further. In this paper we demonstrate that significant improvements result when advanced RTM tools are used for salt imaging even in the Santos Basin in offshore Brazil where the salt geology is relatively simple compared to the Gulf of Mexico.
