Field design and operation of a novel deepwater, wide-azimuth node seismic survey

Many new deepwater, subsalt Gulf of Mexico developments are afflicted by poor imaging caused by the complex nature of their salt overburdens. The Atlantis Field is an example; a poor image of its northern flank hindered development. The ocean-bottom seismic (OBS) autonomous node method was applied with the goal of substantially improving the subsalt reservoir image.
