P034 CRS-Based Minimum-Aperture Time Migration - A Real Data Example M. Kienast (Geophysical Institute University of Karlsruhe) M. Spinner (Geophysical Institute University of Karlsruhe) & J. Mann* (Geophysical Institute University of Karlsruhe) SUMMARY The achievable image quality and the reliability of amplitudes in Kirchhoff migration strongly depend on the selection of the migration aperture. Optimal amplitudes are obtained if the migration aperture is restricted to the constructively contributing part of the reflection event which is related to the size of the projected Fresnel zone. The Common-Reflection-Surface (CRS) stack provides kinematic wavefield attributes that allow to address this problem together with
