A production 3D preSDM project from the southern North Sea using several vintages of input data was run using a velocity-depth model common to the whole area, with good final results. The expected...
Over the past few years, many techniques have been presented for updating the velocity depth model required for full-volume 3-D prestack depth migration (preSDM). These techniques (many of which are...
Acquiring large-aperture seismic data (38 km maximum offset) along a profile crossing the Faeroe–Shetland basin in the North Atlantic enables us to use wide-angle reflections and refractions, in...
