Assessment of Undiscovered Oil and Gas Resources of the Levant Basin Province, Eastern Mediterranean  
Assessment of Undiscovered Oil and Gas Resources of the
Levant Basin Province, Eastern Mediterranean

The U.S. Geological Survey estimated a mean of 1.7 billion barrels of recoverable oil and a mean of 122 trillion cubic feet of recoverable gas in the Levant Basin Province using a geology based assessment methodology.



The Levant Basin Province encompasses approximately 83,000 square kilometers (km2)



Geologic cross section of the southern part of the Levant Basin Province illustrating the definition of the three assessment units (AU) in this study. The areas of the Levant Sub-Salt Reservoirs AU and the Plio-Pleistocene Reservoirs AU are coincident, and neither AU overlaps with the Levant Margin Reservoirs AU. Dashed line separates Cenozoic (above) from pre-Cenozoic rocks. Messinian-age salt (between the M and N seismic horizons) is shown in green. Location of schematic section (A-A’) shown in figure 1. A, Permian to Aalenian age; B, Bajocian to Turonian age; C, Senonian to Early Oligocene age; D, Oligocene to Late Miocene Age; E, Late Miocene (Messinian) age;
F, Plio-Pleistocene age rocks. Modified from Gardosh and Druckman (2006) and Cartwright and Jackson (2008).

For this assessment the Mesozoic-Cenozoic Composite Petroleum System was defined to include the possibility of viable petroleum source rocks of Triassic, Jurassic, Lower Cretaceous, Upper Cretaceous, Miocene, and Plio-Pleistocene ages, all of which have been suggested as potential source rocks within this province.



Levant Basin Province assessment results.
[MMBO, million barrels of oil; BCFG, billion cubic feet of gas; MMBNGL, million barrels of natural gas liquids. Results shown are fully risked estimates. For gas accumulations, all liquids are included as NGL (natural gas liquids). Undiscovered gas resources are the sum of nonassociated and associated gas. Largest mean oil field in MMBO; largest mean gas field in BCFG. F95 represents a 95 percent chance of at least the amount tabulated. Other fractiles are defined similarly. TPS, total petroleum system; AU, assessment unit. Gray shading indicates not applicable]
