oa Sensitivity Considerations in Building Velocity Models for the Nile Delta’s Messinian

The typical offshore Nile delta Messinian section is considered one of the toughest challenges that face the depth imaging of the Pre-Messinian structure. The post Messinian section shows a uniform gradient of sonic velocities. Given a good initial interval velocity model that is in accordance with the well sonic, a minimum mis-tie could be achieved with the top Messinian.
