Oil and gas round-up

Operator OKEA has revealed that the recoverable resource estimation at the Talisker Statfjord formation in the Norwegian North Sea has increased from 19 to 28 million barrels of oil equivalents (mmboe). Production is expected in 2027. Total recoverable volume estimates from the Statfjord and Cook formations combined have increased from 16-33 to 23-44 mmboe. The Talisker West discovery is located in the Brage field, 10 km east of the Oseberg field and about 120 km west of Bergen. The wellbore was drilled to measured depth of 10,223 m.

Equinor has started drilling the Raia project in the pre-salt of the Campos Basin, Brazil. The campaign includes six wells in the Raia area, around 200 km offshore Brazil in water depths of around 2900 m. Estimated recoverable reserves exceed one billion barrels of oil equivalent. The project will have the capacity to export up to 16 million m3 of natural gas per day, which could represent 15% of Brazil’s natural gas demand.

Petrobras has discovered gas in the Copoazu-1 exploratory well, in Block GUA-OFF-0, located in deep waters off Colombia. The Copoazu-1 well is 36 km from the coast, at a water depth of 964 m and at a distance of 8 km from the Sirius-1 (discovery) and Sirius-2 (evaluation) wells. Gas-bearing intervals were confirmed through electrical logs and fluid sampling.

Eni has made two gas discoveries in Libya. Two adjacent geological structures, Bahr Essalam South 2 (BESS 2) and Bahr Essalam South 3 (BESS 3), were drilled by the B2-16/4 and C1-16/4 wells, 85 km off the coast in about 650 ft of water, and 16 km south of the Bahr Essalam gas field. Gas-bearing intervals were encountered in both wells within the Metlaoui Formation, the main productive reservoir of the area. The acquired data indicate the presence of a high-quality reservoir. BESS 2 and BESS 3 structures are estimates to jointly contain more than 1 Tcf of gas in place.

Equinor has made an oil discovery that will be tied into the Johan Castberg field in the Barents Sea. The discovery was made in the ‘Polynya Tubåen’ prospect (7220/7-5). The preliminary volume estimate is between 14 and 24 million barrels of recoverable oil equivalents.

Eni has made a significant gas and condensate discovery in Egypt, with the drilling of the Denise W 1 exploration well in the Temsah Concession in the Eastern Mediterranean. Preliminary estimates indicate about 2 trillion cubic feet (Tcf) of gas initially in place and 130 Mbbl of associated condensates. The Denise W discovery lies 70 km offshore in 95 m of water depth and less than 10 km from existing infrastructure. It features a gas-bearing sandstone reservoir of excellent quality with about 50 m of net pay.

Libya’s National Oil Corporation (NOC) and Sonatrach, operator of Contract Area 95/96 in Libya’s Ghadames Basin, have made an oil and gas discovery. The find follows the drilling of the A1-69/02 exploration well, located 70 km from the Wafa field. The well was completed to a final depth of 8440 ft and is delivering production rates of 13 million cubic feet of gas and 327 barrels of condensate per day from the Awynat Wanin and Awyn Kaza formations.
