A03 CONVERTED-WAVE IMAGING IN ANISOTROPIC MEDIA - PART II: 3D APPLICATION AND CASE STUDY FROM THE NORTH SEA Abstract 1 HENGCHANG DAI* 1 XIANG-YANG LI 1 AND PAUL CONWAY 2 1 British Geological Survey 2 Kerr-McGee North Sea (UK) Ltd We present a practical approach to extend the theory and method of converted wave image to 3D dataset by performing the 3D pre-stack Kirchhoff time migration in a PC cluster and to build the migration velocity model. This approach is successfully applied to a 3D-4C OBC dataset acquired in the North Sea to use its PS-waves to image the structure
