Report summary

The Algerian Illizi-Ghadames Basin is a proven petroleum province in a desert setting. Exploration in the basin started in the 1950s, and since then a large number of commercial and technical oil and gas discoveries have been made in Paleozoic and Mesozoic reservoirs – the two key plays in this basin. Explorers in the basin will struggle to create value due, particularly in the Paleozoic Gas play, to harsh fiscal terms and above average development costs.
