P189 TESTING OF DIFFERENT MODIFICATIONS OF MULTIWAVE AVO-ANALYSIS BY MODEL DATA TATIANA V. NEFEDKINA and VADIM V. BOUZLOUKOV Summary 1 The paper presents results of comparative analysis of different wave combinations (PP+PS) (PP+SH) (PP+SV) as applied to inversion of AVO-response. Our approach is based on the combined inversion of a polynomial approximation for dependencies between reflection coefficients of compressional shear and converted waves and incidence angles. Linearized problem has been considered. Accuracy and stability of inverse problem solution have been studied using numerical experiments for two-layered model. An iteration R-algorithm allowing to obtain stable non-biased estimators of elastic parameters of
