Triassic and Ordovician formations were only drilled in parts of the basin and have minor petroleum generation potential. Permian and Devonian samples also had low generation potential, as did samples from the upper part of the Silurian. The Devonian succession is of limited extent as a result of Hercynian uplift and erosion.
Major petroleum generation potential is associated with the lower part of the Silurian Tanezzuft Formation in which high TOC values and moderate to high HI values were recorded. The formation is characterized by abundant fluorescing alginite. Most samples studied were early mature to mid-mature but there was some regional variability.
