Algeria - Exploration History First Activity ª 1890’s (Cheliff Basin) First Commercial Discovery ª 1948 (Oued Gueterini) in North of Algeria. 1950’s z Extension to the Sahara with the drilling of Bg-1 in 1954 z

1956 : Discovery of the Hassi Messaoud and Hassi R’mel giant fields

1990 - 2000 Several Oil discoveries mainly in the Berkine basin in the frame of the partnership. 2001 – 2010 Several gas discoveries ( mainly in Illizi and Berkine) and in the western ones ( Ahnet, Timimoun, Reggane) 2011-2012 : discoveries in new areas ( north of Al i and Algeria d Bechar B h Basin) B i )

Offshore Algeria- Hydrocarbon systems Detritic sedimentary fill Evaporitic sequence (Messinian) ‰ Reservoir: • Serravallian‐Tortonian turbidites HBB‐1 (Porosity: 5‐15%). • Oligo‐Miocene Oli i ( (Numidian idi Flychs l h ?) in i the extreme eastern part. • Lower Pliocene turbidites (Good Porosity); ) ‰ Source rocks: • Miocene Shales (TOC 1.5%) • Serravallian‐Tortonian Shales • Messinian marls in HBB‐1 well.
