The Algerian oil company, Sonatrach, announced on Tuesday two new discoveries of oil and gas in two new perimeters in the south of the country.
The Algerian group presented on Tuesday the results of two new boreholes in Touggourt and El Bayadh, two regions in the southeast and southwest of the country.
“As of March 22, 2022, Sonatrach successfully completed a West Oglet En Nasser-2 (WOEN-2) delineation well in the Touggourt Est I perimeter, located north of the Hassi Messaoud field. The WOEN-2 delineation well, located about twenty kilometers from the Rhourde El Amar processing facilities, confirmed the northward extension of the reserves in place of the Oglet En Nasser crude oil field, discovered in the reservoirs, from the Lower Triassic Series and the Ordovician Grés d’Ouargla”, indicated the Algerian company.
According to the same press release, “this well has confirmed useful heights of 15 and 13 meters respectively in the Triassic and Ordovician”. “The production test carried out with the main objective of the triassic produced oil and associated gas with flow rates of 5,094 barrels/day of oil and 185,582 m3/day of gas. The estimate of volumes of crude in place (proven + probable), before the drilling of the WOEN-2 delineation well, was estimated at 546 million barrels”, underlined the same source.
The positive result of this well indicated Sonatrach, “allowed a revaluation of these volumes to 961 million barrels, with a contribution brought back by the WOEN-2 delineation well, estimated at 415 million barrels”. In addition to the Triassic, which is an objective developed in this region, the Ordovician reservoir is considered, added to the same document, as an emerging petroleum zone and is currently the subject of numerous studies and major exploration efforts to assess its potential.
“With this discovery, Sonatrach confirms the great oil potential of the Touggourt region and intends to accelerate the development of this pole to increase national production,” the company pointed out.
The second discovery took place in the south-west of the country, more precisely in the wilaya of El Bayadh where the Algerian oil group announced: “to have successfully tested during this month of March, the exploration well Ouled Sidi Cheikh-1 (OSC-1) in the El Ouabed perimeter, located about 158 km west of Hassi R’Mel”.
This drilling, underlined the same source, “highlighted a discovery of crude oil and associated gas in the Lias carbonate reservoir”. “The production test performed in this reservoir yielded crude oil and associated gas with flow rates of 925 barrels/day of oil and 6,456 m3/day of gas,” the statement said.
The results of this well, indicated the same source, “come to enhance the oil potential of the Sillon de Benoud and will eventually allow the emergence, north of Hassi R’Mel, of a new hydrocarbon pole, which will be confirmed by drilling the many prospects and leads mapped in this region as well as the delineation work of the discoveries made to specify the volume of the reserves”.
