RTM technology improves salt imaging in the Santos basin ///

Reverse Time Migration (RTM) has been used extensively in the comparatively complex geological domain of the deepwater Gulf of Mexico. RTM technologies employed in the Santos basin offshore Brazil have demonstrated significantly more accurate salt geometry definition and velocity than ray-based migrations. The superior images of salt structures clear the way for a more accurate interpretation of the salt geometry. Furthermore, in areas where poor illumination inhibits conclusive interpretation, RTM with selective Vector Offset Output (VOO) stacking can improve signal-to-noise ratio and aid interpretation.
