A25 3D HIGH-RESOLUTION VP/VS INVERSION: EXPERIENCES FROM RECENT CASE STUDIES Abstract 1 Recently we introduced a new scheme for 3D high-resolution vp/vs estimation by automating the PP PS event correlation process[1]. The scheme allows transferring the PS cube to the PP domain and thus enables a joint analysis of the data sets. Since event correlation is automated here the turn around time is significantly reduced and simultaneously precision is gained compared to the traditional horizon based manual approach. Furthermore the high-resolution vp/vs often lends itself as a lithology indicator. We will review the algorithm with respect to its robustness generality
