The Nafoora oilfield is situated on a major tectonic uplift in the eastern Sirte Basin, the Amal‐Nafoora High. Four oilfields have been discovered on this uplift – Amal, Rakb, Augila and Naffora. Drilling on this high encountered hydrocarbon entrapment in over a dozen distinct stratigraphic units. These reservoirs range in age from Pre‐Cambrian basement to Miocene sands. The most important reservoirs in the Nafoora field are the sandstones of the Amal (Cambro‐Ordovician) and Maragh (Upper Cretaceous) Formations. Reservoirs in the Upper Cretaceous, Palaeocene and Eocene carbonates are as important as those in the sandstones.
