The Eastern Mediterranean region proven to be world-class, frontier deepwater hydrocarbon province.
More than 60 Tcf of natural gas were
discovered offshore Israel, Cyprus and Egypt; e.g. Tamar field (world’s largest deepwater natural gas discovery in 2009).
New plays have been confirmed in un-explored areas; e.g. Zohr field (carbonates, offshore Egypt).
In addition, the giant gas province of the
Nile Delta –increase up to 42 Tcf of gas reserves.
The Levant Basin is characterized by a lack of data, a complex geodynamic history, and high exploration costs. Recent seismic acquisitions and interpretations place it as ‘natural laboratory’ for improving numerical modelling.

EAST MEDITERRANEAN CRUSTAL MODELING - 2018
• What is the architecture and the nature of the crust in the Levant basin and surroundings?
• How can the crustal evolution be recreated with integrated geophysical data analysis?
• How does understanding crustal characteristics help in constraining the heat flow evolution (major input for sedimentary basin models)?
Constraining tectonic evolution
Improving earthquake evaluation
Rigidity of the crust
Properly assessing petroleum systems

Stratigraphic Model Mesozoic
Numerical simulation were achieved interval by interval (separately) and were calibrated by the means of the geological conceptual models. The progradation of the Jurassic platform carbonates along the Levantine margin and the Base Cretaceous regressive sand cycles were, hence, properly simulated.
