Abstract
C-02 IMPROVED IMAGING BY PRE-STACK DEPTH MIGRATION OF MULTI-AZIMUTH TOWED STREAMER SEISMIC DATA Summary 1 STIAN HEGNA and DOROTHEE GAUS EAGE 65th Conference & Exhibition — Stavanger Norway 2 - 5 June 2003 PGS Geophysical Oslo Norway Seismic imaging is a major challenge over the Varg Field in Block 15/12 offshore Norway due to complex salt structures and a high velocity Chalk layer above the target levels. The original 3D survey covering the Varg Field has been processed many times to try to improve the quality of the seismic data. In spite of all the processing attempts seismic imaging remained
