Many authors have written about the imaging benefits of multi-azimuth seismic data, extolling the virtues of this type of acquisition as a way to defeat multiple diffractions, improve illumination and produce a better stacked image. Consequently, multi-azimuth streamer seismic data holds out the promise of producing a seismic image much richer in signal and resolution than its single azimuth equivalent. This acquisition strategy in the offshore environment could ultimately allow a much clearer picture of the subsurface where one had not existed before. A number of studies have borne this out, showing the benefits for interpretation of structure and seismic stratigraphy. Beyond these well understood benefits of multi-azimuth seismic for imaging, these data may also offer a unique opportunity to further characterize the reservoir based on multiple independent measures of the overburden and reservoir. The purpose of this paper is to present a case study at the Raven discovery utilizing multi-azimuth data for reservoir characterization and uncertainty analysis.
