Examples of 3D Noise Attenuation Processes Applied to Land and OBC data Simon Shaw (ConocoPhillips) Chuck Mosher (ConocoPhillips) Stephen Chiu (ConocoPhillips) Yunqin Shen (ConocoPhillips) Jack Howell (ConocoPhillips) and Mark Wuenscher (ConocoPhillips) SUMMARY____________________________________________________________ Land and ocean bottom seismic data can be readily acquired with wide azimuth acquisition geometries. The orthogonal cross spread has advantages for noise attenuation including that ground roll can be well sampled and these 3D gathers allow for the application of more powerful 3D processing algorithms. In this workshop we will present a variety of synthetic and field data results that compare and contrast some of these 3D
