Paper Summary
The recent Nefertari gas discovery in the Western Mediterranean offshore Egypt, has proved the
potentiality of the area for hydrocarbon exploration; however, exploration remains challenging due to complex regional geology. Seismic imaging is particularly impacted by velocity heterogeneity within the Messinian layer, driven by interactions between mobile mud, sand bodies, and variable salt-anhydrite compositions.
To address these issues, a robust velocity model building (VMB) workflow integrating Full Waveform Inversion (FWI) and Reverse Time Migration (RTM) is performed (Brandsberg-Dahl et al., 2017). This abstract presents examples from a recent acquired NAZ seismic survey in the Eastern Mediterranean, showcasing how advanced VMB techniques improve imaging in such complex regime.
