GEOGRAPHICAL SETTING

Northeastern offshore Tunisia.

2200 km². 

PREVIOUS EXPLORATION

About 312 Km of 2D seismic have been recorded over the area, but no wells have been drilled

GEOLOGICAL SETTING

The Raf Raf block is situated in the northeastern part of the southern Alpine chains. It belongs to a complex domain of nappes, thrusts and grabens.
This part is dominated by Upper Miocene compressional structures, reverse and thrust faults mainly oriented NE -SW .

HYDROCARBON POTENTIAL

Reservoirs :
The main reservoirs in the block are the Campanian - Maastrichtian Abiod fractured chalky limestone and the Ypresian Bou Dabbous limestone which is producing oil southwest of the block( Al Manzah onshore field ).
The Oligocene Fortuna sandstone , the Langhian Ain Grab limestone and the Middle Miocene Nilde limestone constitute secondary objectives in the block.

Source Rocks :

The Albian Lower Fahdene shales and the Ypresian Bou Dabbous limestone are the main source rocks in the Raf Raf block.

Traps :

The traps are mainly structural and related to Tertiary NW-SE compressions and the NE - SW distentions.These traps include anticlines and folds associated with reverse faults and thrusts.
