oa Fractured Basement Exploration on the Algerian Sahara Platform Applied New Play Concept on the Ramade Horst

On the Ramade Horst, the fractured granitic basement at a depth of 1900m has been an active tectonic zone during the Austrian phase. The Silurian is unconformably overlain by the Albian resulting in 2000m of uplift which resulted in the Silurian hot shales being downthrown along the Ramade fault and juxtaposed with the Cambrian and the Basement. The weathered material, the low permeability of the Cambrian/R3 and the Ante-Cambrian shales would be a potential top seal separating the Basement from the Cambrian. Exploration of this unconventional target in the existing fields is recommended as a mean to increase the production and extend the lifetime of the facilities. Also in the Ramade this play can be bundled with the Cambrian.
