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 beam migration algorithm in situations where synthetic zero-offset input data are multi-valued because of caustics of different geometrical structure and observed dimming and distorting phenomena on the migration image in the presence of a low-velocity lens.
