Abstract

A large-scale pre-stack seismic inversion project was carried out in one of the concessions in the Khrisha-Godavari Basin, Eastern Offshore India. The objective was to produce elastic and petrophysical property volumes from seismic data that could be used to optimally locate appraisal and development wells in the complicated Plio-Pleistocene deep water channel complexes. In addition a Bayesian probability analysis was conducted in order to predict the main litho-facies and their associated probabilities. Drilling results have confirmed the elastic properties, lithology classification and petrophysical properties derived from the pre-stack inversion of the seismic data. More wells are expected to be drilled and integrated to further fine tune the above relationship
