Geodynamics of the Levant ProvinceGeodynamics of the Levant ProvincePaleotectonicPaleotectonic EventsEvents
Five main tectonic events have modelled the geological evolution of this region:
• TriassicMiddle Jurassic rifting (Tethys)
• Mid JurassicLate Cretaceous (Turonian): passive marginsedimentation
• Senonian plate reorganisation (Oceanclosure)
• Late Cretaceous (Senonian)Miocene:compressional tectonics and inversion(Syrian Arc folding); extensional tectonics (Lebanon)
• Late Neogene transpressional tectonics(Neotectonics)

Three proven regional hydrocarbon plays:
• Play 1 – SubSalt Biogenic gas in OligoceneLower Miocene turbidite sands, Levantine Basin.
Primary exploration play of the Levantine Basin
• Play 2 – PostSalt Biogenic gas in Lower Pliocene turbidite sands, Levant Margin.
• Play 3 – SubSalt Thermogenic gas/light oil play inLower Cretaceous sands and Jurassic limestones,Levant Margin.
Potential play in the Levantine Basin, in reservoirs associatedwith the Senonian unconformity or in deeper Mesozoic targets.

Offshore CyprusNW Syria thrust area:
Basins of variable size with active subsidence since Middle Miocene along subparallel SWNE/trending strikefault systems.
• Iskenderun Bay:Natural gas discoveries onshore in deltaic/marine sandstones of MiddleUpper Miocene age. Two small undeveloped oil discoveries present offshore.
• Adana: one producing oil field and two old, undeveloped gas discoveries.
Structurally complex basins with fair to good potential for Miocene and Messinian/Pliocene gas plays.

ConclusionsConclusions
Offshore Cyprus straddles the tectonic boundary between two tectonic plates, with basins displaying different stratigraphic and structural histories.
As a result, varied and diverse basinspecific exploration plays are present.
As proven by the Aphrodite1 well discovery, the Lower Miocene biogenic gas play (the primaryplay in the Levantine basin) occurs offshore Cyprus, to the southeast of the island (Block 12).
Additional exploration opportunities are expected in:
•MioceneCretaceous carbonates associated with the Eratosthenes Seamount;
• OligoceneMiocene turbidite sands of the West Eratosthenes basin;
•Messinian & PlioQuaternary channel sands and turbidite fans in the Herodotus basin;
•Middle Miocene to Pliocene marine sands in basins to the east associated with the Cyprian Arc folds.
