Abstract
This paper illustrates the nature of the Levantine Basin and adjacent areas based on an analysis of<br>modern seismic data. It shows that the Basin is comprised of a substantial thickness (> 10,000<br>metres) of Mesozoic to Cenozoic sediments above a rifted terrain of probably Triassic- Lower Jurassic age.<br>Depth imaged sections are used to show the nature of the Basin including its relationship to the<br>Eratosthenes Seamount and the Larnaca Thrust Zone.<br>Depth imaged sections (with Time Migration comparisons) are also used to illustrate some of the<br>numerous plays seen in the area. These consist of:<br>1)Jurassic and older: faulted structures, rollovers and basin margin plays.<br>2)Upper Jurassic to Middle Cretaceous: mounds, reefs, progrades, drape structures,<br>structural/stratigraphic plays and unconformity plays.<br>3)Middle Cretaceous to Paleogene: anticlines, fault blocks, rollovers, mounds, drapes,<br>structural/stratigraphic plays and basin margin pinch-outs.<br>4)Sub-Salt (with salt as the seal) and Intra-Salt (Messinian): pinchouts, bright spots, channels and mounds.<br>5)Post Salt (Pliocene to Recent): channels and mounds.<br>Depth imaging of the seismic data is shown to aid the evaluation of many of these plays and to<br>highlight the prospectivity of offshore Lebanon, Syria and Cyprus.<br>Reference will also be made to both the ongoing and future bid rounds; and to some of the issues<br>involved in producing velocity models for Pre Stack Depth Migration including the subsequent time<br>conversion of depth migrated data.
