Sonatrach Strikes Gas in Southwest Algeria



Sonatrach has made two gas discoveries in southwestern Algeria, one in the Ahnet Basin and one in the Gourara Basin. Sonatrach has 100% stake in the Ahnet Basin discovery and the Gourara Basin discovery was made in partnership with StatoilHydro.

The discovery at OTS-2 (Oued Tesa Araret-2) is located on the perimeter Tidikelt (Block 338a) in the Ahnet Basin. This well produced gas from two reservoir formations encountered at depths of less than 1200 meters. The gas flows on a 32/64" choke were respectively 9743 cubic meters per hour with a wellhead pressure of 1280 psi and 5737 cubic meters per hour with a pressure of 682 psi.

The second gas discovery was conducted in partnership with StatoilHydro. The TNK-1 (Tinerkouk-1) well produced gas from the Carboniferous reservoir about twenty meters thick. The gas flow were approximately 6971 cubic meters per hour with a pressure of 1109 psi on a 32/64" choke. This well is located on the perimeter Hassi Mouina (block 321b) in the Gourara Basin.

These results highlight the promising character of this region for future exploration. These two wells bring the number of discoveries to 18 this year. Seven drilled by Sonatrach as the operator and eleven in partnership with other companies.
