The firm made the first condensate gas discovery in two Devonian reservoirs, following the drilling of an exploration well named In Ekker Sud West-1 (IEKSW-1).
Located in the Amenas 2 research perimeter of the Illizi basin, the well recorded test flow rates of 300,000m³/d of gas and 26m³/d of condensate from the first tank.
It also reported 213,000m³/d of gas and 17m³/d of condensate from the second tank.
Sonatrach also had positive results during the drilling of the Tamzaia-3 (TAMZ-3) delineation well on the Taghit research perimeter of the Bechar basin.
During the Siegenian (Lower Devonian) reservoir formation test, the firm obtained ‘interesting gas production’ at the well.
In a press statement, Sonatrach said: “This result thus highlights a gas potential in this previously untested reservoir in a region considered to be an emerging domain.”
Sonatrach and its partner Eni discovered crude oil following the drilling of the Rhourde Oulad Djemaa Ouest-1 (RODW-1) exploration well in the Sif Fatima 2 research perimeter in the Berkine North basin.
The RODW-1 well, which is the third in the five-well exploration drilling campaign in the region, encountered oil and associated gas in the Triassic sandstones of the Tagi reservoir.
During the production test, the well reported production rates of 1,300bpd of oil and approximately two million standard cubic feet per day (MMscfd) of associated gas.
The Sif Fatima II concession is operated by a joint venture between Sonatrach (51%) and Eni (49%).
In March 2022, Eni and Sonatrach made a significant oil and gas discovery in the Zemlet el Arbi concession, following the drilling of the HDLE-1 well.
The HDLE-1 well delivered 7,000bpd of oil and 5MMscfd of associated gas during the production test.
