Attar 5 POTENTIEL DE GAZ EN PLACE (Ref: Sonatrach - 2013) PROSPECTIVE RESOURCES BASED ON GEOCHEMICAL MODELING: Considering that 10 to 40 % of the total volume generated from the two main source rocks (Silurian & Frasnian hot shales) remains within the shale gas plays, result in a GIIP of 2650 to 10585 Tcf range from a total generated of 26450 Tcf.

For comparison, TRR of shale gas for the USA is : 665 Tcf (source EIA 2013). Recovery Factors: 20 to 50% for Barnett shale, 30% Haynesville shale, 20 to 40% Marcellus shale. 17/11/2014 A.
