Abstract

Summary

The benefits of moving from acoustic full-waveform inversion (FWI) to elastic FWI have now been demonstrated in case of complex geology in the offshore contexts. With onshore data, there are also high expectations about the potential benefits of moving to elastic FWI. This is of particular interest in the Middle East, where the near-surface heterogeneities consist of alternating layers of shales and carbonates, resulting in very strong velocity contrasts that create strong elastic effects including energetic and dispersive surface waves, converted waves and numerous multiples. With this work we contribute to the debate on the advantages of transitioning from acoustic to elastic land FWI. We have investigated here the potential improvements that high-resolution elastic land FWI can bring compared to acoustic land FWI, by adding multi-parameter joint inversion of P- and S-wave velocity models and a selective attenuation of the surface waves to our elastic land FWI toolbox.
