P353 AVO Analysis for Converted Wave T.S. Chen* (SINOPEC & China University of Geosciences) & X.C. Wei (Exploration Production Research Institute SINOPEC) SUMMARY AVO analysis for converted wave (PS) is presented as a complementary tool for PPAVO analysis. Although shear information can be accessed through the AVO response of the PP waves the converted wave provides direct and more accurate information about the shear properties of the subsurface because the reflection coefficient of converted wave is only the function of contrast of shear wave velocity and density. Getting this improved information about the elastic properties of the subsurface is indeed
