Abstract
The value of a regionally calibrated seismic dataset NAGECO
Exploration in the Mediterranean Sea has experienced significant renewed interest over the last decade, with exciting, play-opening discoveries in Israel, Egypt and Libya. ION has taken an innovative approach in order to rapidly and cost-effectively develop an integrated dataset to aid understanding of the whole Mediterranean, which can be used as the framework for future exploration programmes and to challenge existing basin models. The dataset consists of newly acquired BasinSPAN data and reprocessed data from both industry and academic sources. These surveys have been processed concurrently to provide a consistent velocity model across the Mediterranean and generate a fully integrated geological and geophysical interpretation using seismic, well, gravity and magnetic data. ION has created a unique dataset in the region to support the next phase of exploration, with licence rounds expected in the near future.

Integrated seismic datasets
The offshore Mediterranean basins are the focus of renewed interest since the 2008 discovery in Libya, the Tamar and Leviathan discoveries in Israel, and the recent Zohr discovery in Egyptian waters. ION’s regional Mediterranean programme demonstrates the utility and exploration value of a fully integrated seismic dataset and velocity model across the entire basin. Interpretation of these data provides the context to correlate known discoveries into those new and complex underexplored areas.
