LA SKHIRA


GEOGRAPHICAL SETTING

Eastern offshore Tunisia.

ACREAGE

3984 km².

GEOLOGICAL SETTING

The SKHIRA block lies within the western Gulf of Gabes, which acted during the Early Mesozoic as a subsident zone, in the eastern continuation of the Chott Fejaj Basin. Since the Cretaceous, the area evolved as a shallow marine carbonate - evaporate platform and was affected by NW - SE faulting system, with associated horsts and unconformities.

PETROLEUM SYSTEM

Reservoirs and Seals

  • The primary reservoirs are the Cenomanian Zebbag carbonates and the Jurassic Nara dolomites and limestones.
  • The Triassic sandstones may be an additional target.
 

Source Rocks

  • The Jurassic organic rich shales are considered as the main source rock in the area.
  • Deeper Triassic and/or Paleozoic source beds may also provide additional sourcing.
 

Traps

Faulted blocks and anticlines are the main trap types
