The study area located in the western part of the Gulf of Gabes basin
is limited to the north and to the south respectively by Sfax and
Mednine offshore, to the west by Gabes shoreline and to the east by
the Pelagian sea (Fig. 1). This area is considered as one of the most productive
oil provinces in Tunisia with multiple exploration targets.Many
productive oil and gas fields have been discovered in the southern part
of the Gulf of Gabes (Ben ferjani et al., 1990;Mejri et al., 2006). Main objectives
are located within the Cretaceous carbonates and siliciclastic
Formations. Excellent examples of exploration success are found in
the El Bibane Field (producing from the carbonates of Cenomanian
Zebbag Formation and Middle Jurassic Krachoua Formation), the
Ezzaouia Field (producing from dolomites of Cenomanian Zebbag
Formation and sandstones of Upper Jurassic M'Rabtine Member) and
the Robbana Field (producing from sandstones of Early Cretaceous
Melloussi Formation).
