Proven Hydrocarbon Play
• Reservoirs:
Main reservoirs proven
regionally in Jurassic and
Cretaceous sections

In Bearn Des Gaves Permit
Barremian, Neocomian,
Kimmeridge are the main
potential targets.

Note: no direct analogues for
gas zone in Berenx 1 but
Portlandian & Kimmeridgian
dolomites exist up dip within
Berenx shallow closure.

• Sources
Upper Jurassic Kimmeridge
Clay Fm, Lons Fm
Lower Cretaceous Barremain
lime- stones and dolostones

• Seal
Lower Aptian shales & Albian
shales. Lime-mudstones
(intra-formational &
unconformities)
