PP and PS Joint Inversion - A Case Study from West Africa

We present results of a joint PP- and PS-wave AVO inversion from a multicomponent dataset acquired offshore West Africa. We compare these results with the output of the single, P-wave only, inversion. In both realistic synthetic examples and real data the joint inversion produces a better estimation of the shear impedance reflectivity and of the pseudo Poisson’s ratio reflectivity compared with the single inversion.
