ACREAGE

4552km².

The TIBAR block lies in Northern to Northwestern Tunisia which is characterized by numerous elongate outcrops of Triassic evaporates. This domain includes the imbrication zone and northern Tellian Atlas sheet. The block is marked by the presence of Tertiary grabens trending NW-SE and E-W.

PETROLEUM SYSTEM

Reservoirs and seals

  • The main targets in the block are the Ypresian Bou Dabbous fractured limestone, the Campanian Abiod fractured chalky limestone and the turbiditic M'cherga sand-bodies as well as the Cenonamian-Turonian Bahloul laminated limestone.
 

Source Rocks

  • The effective source rocks are the Ypresian Bou Dabbous organic-rich limestones, late cenomanian – Early turonian Bahloul laminated limestones, Albian lower Fahdene black shales and Barremian M’Cherga black limestone.
 

Traps

  • The trap types are mainly structural including faulted anticlines, subsalt and salt dome-related traps roll-over anticlines. Stratigraphic traps include Upper Cretaceous buildups and Lower Cretaceous turbiditic sandstones.
