Summary
The Outer Vøring area in the Norwegian Sea has attracted increasing exploration interest in recent years. However, the region presents several challenges, including volcanic intrusions, remobilized ooze, and fault shadows. In this paper, we present a case study from the Outer Vøring area where we applied a Multi-Parameter Full Waveform Inversion (MP-FWI) workflow to derive a detailed velocity and Q model, along with a reliable angular impedance estimation. Furthermore, we demonstrate the advantages of a least-squares based imaging algorithm compared to a standard approach, both for structural imaging and quantitative interpretation (QI) purposes.
