Lebanon PSDM MegaSurvey 3D

Essential 3D coverage for prospecting in Lebanon’s offshore exploration blocks
Website Map for Survey Lebanon PSDM
Covering unlicensed acreage in offshore Lebanon the PGS’ 10 000 sq. km PSDM cube is key in understanding the petroleum system and evaluating potential prospects in the Levantine Basin. The 3D data meets the data requirement for the offshore licensing round.
Several potential play types have been defined including elongated 4-way closing sub-salt structures with Miocene sandstone reservoirs of distant Nile Delta sediments and stratigraphic traps. The Levant Margin to the east of the survey is known to consist of oil-prone Mesozoic carbonate reef plays.
Acquired in cooperation with the Lebanese Ministry the high quality surveys provide crucial seismic clarity in this frontier region that to date has no well information. Optimal quality has been ensured by industry leading PSDM processing to produce superior imaging of sub-Messinian salt structures.
