The Algerian Illizi-Ghadames Basin is a proven petroleum province in a desert setting. The basin borders Libya in the southeast, Tunisia in the northeast and is bounded to the west by the Oued Mya Basin. Exploration started in the 1950s, and 28.1 bnboe have been discovered in Paleozoic and Mesozoic reservoirs – the two key plays in this basin. Explorers in the Algerian Illizi-Ghadames Basin will have to work hard to create value, due to harsh fiscal terms and above average development costs, but positive returns are possible. The Hydrocarbon Law that came into force in 2013 included fiscal reforms and tax breaks aimed at invigorating exploration. However, it also added fiscal complexity, with taxes and royalties varying according to location, rate of production, plateau production rate, capital spend and profitability. Therefore, project economics will be variable in the basins and require a case-by-case analysis. Full details are available to download in excel and pdf format.
