Semtchenok (St.- Petersburg Branch of Steklov Math. Institute) & P.M. Popov (St.-Petersburg Branch of Steklov Math. Institute) SUMMARY We present our realization of seismic migration with Gaussian beams. To show the potential of the method we carried out a pre- stack depth migration for the synthetic Marmousi dataset and demonstrated the ability to image complicated geologic structures with fidelity exceeding that of Kirchhoff migration and approaching that of wave-equation migration. In addition we tested the Gaussian
