C017 Interactive Seismic Imaging by Fast Beam Migration F. Gao* (CGGVeritas) P. Zhang (CGGVeritas) B. Wang (CGGVeritas) G. Thomas-Collignon (CGGVeritas) & V. Dirks (CGGVeritas) SUMMARY This paper presents a Fast Beam migration algorithm which has been specifically designed to facilitate very rapid migration turnarounds to allow for interactive velocity model building and validation. The very fast imaging turnaround is achieved by only migrating pre-picked events in a wavelet by wavelet fashion. Coherent noise and migration artifacts are reduced compared to classical Kirchhoff migration techniques by using a sophisticated event selection scheme during the event picking phase and by subsequent multi-path
