• Mj Major Objectives: Obj i<br />
– 3D <strong>petroleum</strong> system model that integrates <strong>source</strong> <strong>rock</strong><br />
characterization <strong>and</strong> distribution with the evolution <strong>and</strong><br />
filling of the structurally complicated Levantine Basin,<br />
offshore Lebanon<br />
– The model will simulate the distribution of gas <strong>and</strong> oil<br />
accumulations derived from <strong>source</strong> <strong>rock</strong>s, , whose<br />
characteristics could be inferred from field sampling <strong>and</strong><br />
geochemical analyses.<br />

Studying the potential <strong>source</strong> <strong>rock</strong>s <strong>and</strong> assessing their<br />
efficiency using modern geochemical <strong>and</strong> optical methods:<br />
• TOC TOC, TIC TIC, S<br />
• Rock‐Eval<br />
• GC GC, GC GC‐MS MS<br />
• Oxygen <strong>and</strong> Carbon isotope analyses<br />
• Kinetics of f Hydrocarbon d b Generation<br />
• Microscopy (VRr, Fluorescence, SEM)<br />
