Lower Devonian Combined Traps – Ahnet Basin – Western Sahara

B19 LOWER DEVONIAN COMBINED TRAPS – AHNET BASIN – WESTERN SAHARA The Ahnet basin located in the western part of the Saharan Platform (figure1) exhibits several features witnessing very important and complex structural history . Actually various trends of large scale folds can be seen in outcrops and subsurface. This makes the area very exciting for hydrocarbon exploration. Indeed the first well that penetrates the stratigraphic column of the basin was realized 1950’s. Since exploration was focused on Ahnet basin several gas accumulations were discovered in various reservoir formations of several ages like the Ordovician Lower Devonian and Tournaisian –Strunian
