Abstract

As Ocean-Bottom Node (OBN) full-azimuth surveys becomes ever more popular in deep water environments, so processing algorithms and workflows have been, and continue to be, developed to maximise data quality. A full processing sequence in this West Of Shetland case study addresses key issues such as clock-drift, node positioning, correction of water column variations, directional deconvolution, and free-surface multiple attenuation. To give complimentary insights, the downgoing wavefield was mirror-migrated in addition to imaging the upgoing wavefield. Challenges relating to the acquisition geometry were encountered and addressed.
