Definition of New Play Concepts in the Algerian Offshore

The Algerian offshore belongs to the southern margin of Algero-Provençal and
In the Western Algerian offshore just one exploration well (HBB-1) was carried out, the definition of the petroleum system remains uncertain. The difference in the structural style may have a direct impact on the type of plays. Thus we can have several petroleum systems depending on (02) two previously defined basins.
1. The Algero-Provençal basin : This basin may show two types of plays. The first Type is situated in the front of the inner zones of the chain, is associated with ramp anticlines which develop during the thrust phases southward .. The second Type, is associated to the tilted block systems which develop in the back of the inner zones . This particularly concerns Oligo-Miocene to Quaternary formations.
