Abstract

Summary

Recent projects have demonstrated that innovative survey design can improve the imaging of the pre-Messinian interval in the Eastern Mediterranean. These include the deployment of multiple source vessels in Extended Long Offset (ELO) or half-Wide-Azimuth (hWAZ) configurations and ocean bottom node surveys (OBN). Use of low frequency sources is another significant development. Here we describe how the newest developments in these trends have the capability to further improve imaging in the pre-Messinian. First, we demonstrate the uplift over narrow-azimuth data that is seen in the latest implementation of an hWAZ configuration deployed offshore Angola. Next we highlight improvements in source side efficiency for sparse OBN surveys and describe how we iterate over survey design practices when working with low frequency sources in exploration settings.
