P076 COMMON-REFLECTION-SURFACE STACK FOR COMMON OFFSET: PRACTICAL ASPECTS AUTHOR(S) S. BERGLER G. HÖCHT Y. ZHANG and P. HUBRAL Address Geophysical Institute University of Karlsruhe Hertzstr. 16 76187 Karlsruhe Germany Introduction. In the last years the Common-Reflection-Surface (CRS) stack has been established as a real alternative to standard seismic reflection imaging routines such as the CMP stack or the NMO/DMO/stack. The CRS stack provides a simulated zero-offset (ZO) section from 2-D multi-coverage prestack reflection data without any knowledge about the macro-velocity model (see e.g. Mann et al. 1999; Hubral 1999). In case of a 2-D laterally inhomogeneous medium the CRS stacking
