SUFAEITULA


GEOGRAPHICAL SETTING

The Sufaeitula block is located in Central onshore Tunisia.

ACREAGE

5108km².

GEOLOGICAL SETTING

The Sufaeitula block lies within the central Tunisia Atlas. It is limited towards the south by NW-SE Gafsa fault and towards the north by E-W Kasserine graben. The surface features exhibit NE-SW trending folds (Djebels: Sidi Aich, Sidi Ali ben Aoun, Kébar) and ENE-WSW (Djebels: Majoura, Melloussi, Bouhedma). The area is transected by NW-SE and N-S strike slip faults. The block was part of a Mesozoic platform characterized by mixed carbonate -evaporite and siliciclastic deposit. The area emerged as part of the Kasserine Island during the Late Cretaceous and Paleogene and then was covered by Mio-Pliocene clastics.

PETROLEUM SYSTEM

Reservoirs and Seals

  • The Jurassic carbonates constitute the primary target within the block.
  • The Cenomanian Zebbag dolomite, the Aptian Orbata dolomite and Lower Cretaceous Sidi Aich, Boudinar and Meloussi sandstones may constitute promising plays.
  • The deep intervals such as Triassic strata may constitute deep target.
 

Source Rocks

  • The Toarcian Middle Nara black shales are a primary source rock in the area.
  • The Mid –Cretaceous Bahloul laminated limestones are locally potential source rocks Traps
 

Traps

The main taps include faulted anticlines and salt traps.
