Eastern Onshore Tunisia.
The Triaga Block is part of the Sahel Platform, which developed east of the North South Axis. The area was affected by Early Mesozoic rifting and associated block faulting and by Mid-Cretaceous to Tertiary compressional stresses and associated NW-SE folding and wrench faulting, in addition Triassic Diapir are also present.
Reservoirs and seals :
The main and well sealed reservois are the Mid-Eocene Reineche Nummulithic limestones, the Ypresian El Gueria Nummulithic limestones, the Upper Senonian Abiod chalky limestones, Turonian-Coniacian Bireno/Douleb bioclastic limestones, Cenomanian Zebbag carbonates and Jurassic Nara dolomites and limestones.
The primary source rock within the block is the Jurassic middle Nara black shales. Sourcing from the adjacent eastern area is likely, where the Albian Fahdene, Upper Cenomanian—Lower Turonian Bahloul and Ypresian Bou Dabbous source rocks are mature.
They include structural traps such as anticlines, faulted blocks and stratigraphic traps close to salt-domes.
