Algeria and Libya Petroleum System Modelling Studies
March 7, 2016
GEOS4 offers two new 2D Petroleum System Modelling studies, covering transects of the Berkine/Ghadames Basin in eastern Algeria and the Jabal Nafusah Area, NW Libya. The models are based on the main source rocks in these areas: the `hot shales` of the Silurian Tanezzuft Formation and the Frasnian shales. Geological evolution, source rock maturity and the... More
