Acquisition Geometry Versus 4C Image Quality - a Study of Statfjord and Gullfaks Sør

F-25 ACQUISITION GEOMETRY VERSUS 4C IMAGE QUALITY - A STUDY OF STATFJORD AND GULLFAKS SØR Summary 1 An evaluation into the effects of different acquisition geometries on image quality for P-wave and PS-wave data for Ocean Bottom seismic survey was carried out. This was achieved through decimation of source and receivers of existing seismic data from both Statfjord and Gullfaks Sør fields. Introduction The benefits of ocean bottom surveys (OBS) in terms of image quality compared to conventional marine streamer surveys have already being demonstrated (Rognø et al). It is seen that OBS surveys by their very nature allow for
