Abstract

To support exploration in the opportunity-rich offshore Mediterranean, the best seismic imaging solutions have to be employed to unveil the complex regional geology. This features a Messinian salt sequence with heterogeneities, lateral thickness variations and sharp velocity contrasts which make the imaging of subtle hydrocarbon traps beneath the salt particularly challenging. These challenges can be overcome with a combination of truly broadband acquisition and advanced processing and imaging techniques which delivers excellent resolution in the shallow section and gives the best chance for imaging below the Messinian. The workflow contains efficient demultiple tackling water bottom and intrabed multiples and very detailed and accurate imaging velocity models.
