P354 An Approach to the AVO-Inversion Problem Based on the Effective Reflection Coefficients L.V. Skopintseva* (Institute of Petroleum Geology and Geophysics) T.V. Nefedkina (Institute of Petroleum Geology and Geophysics) M. Ayzenberg (Norwegian University of Science & Technology) & A. Aizenberg (Institute of Petroleum Geology and Geophysics) SUMMARY The conventional AVO-inversion is based on the applications of the plane-wave reflection coefficients or their linearizations for pre-critical incident angles in media with weakly curved and weak-contrast reflecting interfaces. Since a theoretical AVO-dependence should account for the real curvature and contrast of the interfaces the search of a more adequate mathematical apparatus for
