The Levant Basin – A World-Class Hydrocarbon Province in the SE Mediterranean Sea

Gas and Oil Fields Offshore Israel  Gas and oil fields throughout the - 200 0 basin in both shallow and deep Karish Aphro dite/Is hai water Tanin  Very high rate of success in drilling Tamar Leviathan Tamar the gas play (> 60%) Dalit SW Dolphin  Sub-commercial (at time of discovery) but important oil fields  Favorable geologic conditions for Shimshon generation and accumulation of gas Legend: Noa Oil Field and oil Gaza MariB Gas Field Marine Pipelines

Basin Analysis Study Offshore Israel An integrated Basin Analysis Study was conducted by Beicip-FranLab in 2015 Project goals: Define Petroleum Systems and Plays  Estimate the amount of hydrocarbon resources (Unrisked, Yet-To-Find, Recoverable)  Identify favorable areas for exploration  Provide a regional 2D and 3D integrated models  Regional Geologic Section used for 2D Modelling

Basin Analysis- Source Rock Potential Main Results: TOC (%) TOC (%) TOC (%) TOC (%)  Good source rock for Biogenic Gas in the Oligocene, Miocene and Pliocene (TOC 0.5-1.5%)  Good source rock Jurassic 2 intervals for Oil and Gas in the Lower and Upper Jurassic and Middle Jurassic 1 Cretaceous Jurassic TOC Correlation Difference between pessimistic and optimistic scenarios TOC value Possible correlation

Basin Analysis - Maturity Reconstruction Main Results:  The Oligo-Miocene is in the immature zone (Ro < 0.6%)  The Cretaceous is within the oil to light oil zone (0.6 -1.4 Ro)  The Upper Jurassic can reach the dry thermogenic gas zone

Basin Analysis- Pressure Regime Main Results:  The basin appears to be vertically and latterly compartmentalized  Salt and shale units form low permeability pressure barriers Overpressure (Mpa)

Basin Analysis - Unrisked and YTF Resources Unrisked : in place volumes with no exploration risk calculated Yet-to-find : In place volumes after integration of the chance of exploration success

Basin Analysis – Petroleum Systems and Plays Main Results:  Four main Hydrocarbon plays, three of them proven (Pliocene, Oligo-Miocene, Jurassic) and one is speculative (Cretaceous).  Additional traps are likely found in all plays.
