Sirte Basin
Libya's onshore oil has been discovered mainly in three geological trends of the Sirte Basin: 1) the western fairway, which includes several large oil fields (Samah, Beida, Raguba, Dahra-Hofra, and Bahi); 2) the north-center of the country, which contains the giant Defa-Waha field and Nasser fields, as well as the large Hateiba gas field; and 3) an easterly trend, which has large fields like Sarir, Messla, Gialo, Bu Attifel, Intisar, Nafoora-Augila, and Amal. Overall, the Sirte Basin contains approximately 80% of Libya's proven oil reserves and accounts for 90% of production.
