MC Prestack Joint Inversion S-Impedance Result

Conclusions RCP In pursuit of new ideas • Multicomponent seismic requires more robust acquisition and processing than occurred to add substantial value • Most large lithology variations in Vaca Muerta are smooth enough to be resolved reasonably with low frequencies, leading to highly correlated LF starting model • For P-impedance, post stack inversion may be able to provide comparable P-impedance results to prestack inversion in less time in some cases • Modern wide-azimuth seismic acquisition can add substantial value over legacy mono-azimuth surveys 92
