P046 Practice of 3D VSP Data Migration V.A. Mishin* (Central Geophysical Expedition JSC) S.I. Alexandrov (CGE) V.H. Kivelidy (CGE) & M.V. Perepechkin (CGE) SUMMARY New migration technique of massive 3D VSP data is presented. The method is based on energy hashing algorithm. The technique was applied to real 3D VSP data collection from two Chinese oil fields. The comparison of different migration methods was made. It was shown that the offered technique allows enhance the quality of seismic images of complex geological structure under limited priory information.
