New reservoir age for Zohr discovery
In the last ten years, the Eastern Mediterranean has seen several large gas discoveries, the most recent being the Zohr discovery in Egyptian waters. Initial reports dated the reservoir as purely Miocene in age, but a recent publication by ENI (Bertello et al., 2016) has stated a Cretaceous age for the majority of the reservoir. Thus, bringing a whole new set of questions and implications when exploring for Zohr-type structures and plays.
This new data and understanding has been integrated into the Exploration Insights product suite and used to analyse the exploration implications associated with the Zohr discovery and related petroleum system. Analogue sections for a proposed Albian-Cenomanian rudist-bearing reservoir are identified in onshore Israel (Bein, 1976; Rosenfeld and Hirsch, 2005), together with analogue data on proposed top and lateral sealing facies. The nature and likely location of further offshore occurrences of this and the overlying Miocene reservoir facies are all discussed within the Zohr GeoInsight, as well as the variety of possible charge models that may apply.
