Prestack depth migration and wide-azimuth towed-marine acquisition provided step-change improvements in subsalt imaging during the last decade. Incremental enhancements in image quality were also provided by the development of processing algorithms like one-way wave equation (WEM), two-way wave equation (RTM) and true-azimuth 3D surface multiple attenuation (GSMP) (Dragoset et al., 2008). These compute intensive technologies are now routinely available due to cost effective compute capacity and fast algorithms.
