Processing Ocean-Bottom Seismic (OBS) Data from the White Rose oilfield, offshore Newfoundland

Peter W. Cary and Robert R. Stewart


A four-component ocean-bottom seismometer (OBS) survey was acquired over the White Rose oilfield, offshore Newfoundland in the summer of 2002. The survey consisted of 21 OBS units (normally used in crustal refraction experiments) deployed over 1 km with 12 sources lines from a towed air gun. There were numerous problems with the data, but some promising final sections were achieved for both PP waves (largely on the vertical channel) and PS waves (mainly on the radial channel). Processes applied to the data included data clipping repair, F-K and tau-p filtering, PP and PS stacking, and post-stack migration. Final images indicate considerable promise for multicomponent marine data in this area.
