We show how conventional AVO inversion can be pushed further as a reservoir delineation tool, if viewed as part of larger workflow, which includes gather preconditioning, to increase signal-to-noise ratio and vertical resolution of the seismic data, in addition to an automatic detailed stratigraphic interpretation for reliable background model building. Our strategy includes carrying the whole inversion in a form independent on the low frequency information to retrieve only variations of P and S-wave impedances and density. The estimated models are then combined with their corresponding background model derived using the horizon cube technology. Application to an offshore marine data set illustrates the advantages this methodology brings to prospect evaluation.
