B031 IMPROVED AVO ANALYSIS BY COMMON REFLECTION SURFACE (CRS) TECHNOLOGY Summary 1 The Common-Reflection-Surface (CRS) method which was developed in recent years has increasingly been used for the high resolution imaging of complex subsurface structures. Assuming subsurface reflector elements with dip and curvature the CRS method renders an increased signal-tonoise ratio and additional subsurface information in comparison to conventional NMO/DMO time domain imaging. These advantages of the CRS method however may as well be used for an improved Amplitude Versus Offset (AVO) analysis. A case study shows that the more realistic subsurface assumptions and the increased fold of the CRS
