Traditional marine seismic data are acquired by a seismic vessel sailing in a series of straight lines over a target. However, shooting in continuously linked circles delivers richer datasets with reflection contributions from all azimuths and the added benefit of little or no nonproductive time. Case studies from Indonesia, Brazil, Angola and the Gulf of Mexico demonstrate the benefits of circular shooting for imaging challenging environments such as subsalt and other complex geologic settings.
