Abstract
A-40 THE IMPORTANCE OF WIDE AZIMUTH IN IMAGING 1 B. ARNTSEN and M. THOMPSON Statoil Research Centre Postuttak N-7005Trondheim Norway Summary Comparing 3D depth migrated streamer data and 3D depth migrated OBC data from the same area it is demonstrated that the better quality of OBC data is related to the relatively wider azimuths used in the OBC data acquisition geometry. Introduction The benefits of wide azimuth acquisition geometries have been recognized for a long time in land seismics (Cordsen and Galbraith 2002). Offshore true 3D OBC data has recently become available and the importance of better azimuth coverage both
