This paper presents an updated review of the petroleum prospectivity of Lebanon. It is based on a re-assessment of the tectono-stratigraphic succession in Lebanon, correlation with nearby countries and the results of a recent offshore seismic survey. A generalized model illustrating potential petroleum system(s) in Lebanon is presented with data on Palaeozoic, Mesozoic and Cenozoic plays. Major lithological units are described with respect to their source, reservoir and cap-rock potential.

Based on a general review of previous studies and existing data, Lebanese exploration prospects may comprise on- and offshore as well as coastal (margin) targets. They include potential Triassic reservoirs in onshore central-northern Lebanon including those at the Qartaba structure. Offshore plays are discussed with reference to recent seismic profiles; potential offshore targets comprise Oligo-Miocene reservoirs sealed by Messinian evaporites as well as deeper Mesozoic reservoirs.
