Shallow migrating hydrocarbon fluids in western Barents Sea are found to be associated with high seismic amplitudes, and focusing on the Hoop Fault Complex area therein, we have attempted to characterize such shallow high amplitude anomalies. The workflow followed for doing so entails the application of prestack simultaneous impedance inversion followed by analysis in Lambda-rho versus Mu-rho as well as P-impedance versus density crossplot space, and aims at discrimination of anomalies that are associated with the presence of hydrocarbons from those that are not. Finally, we suggest that such attempts be supplemented with the application of spectral decomposition as well as integration with diverse data types such as P-cable seismic as well as CSEM data, so as to come up with an integrated assessment for the prospects and mitigating risk.
