Vår Energi considers new discovery tie in to Goliat field

Vår Energi AS has confirmed a Barents Sea oil and gas discovery in production licence (PL) 901.

 

Preliminary estimates place the size of the discovery at 1.4-1.9 million standard cubic metres recoverable oil equivalent. The licensees will assess the discovery together with other nearby prospects with a view toward a potential development tied into existing infrastructure on Goliat field.

 

Wildcat well 7122/6-3 S, the first exploration in the licence, was drilled by the Scarabeo 8 drilling facility about 10 km south of the 7122/6-1 (Tornerose) discovery about 100 km north-west of Hammerfest. Water depth at the site is 427 metres.

 

The objective of the well was to prove oil and gas in the Realgrunnen Subgroup in reservoir rocks from the Late Triassic to Middle Jurassic age.

 

The well was drilled to a vertical depth of 1,970 metres below sea level and was terminated in the Fruholmen formation from the Late Triassic. It encountered a 28-metre oil and gas column in the Stø formation from the Early to Middle Jurassic, of which 22 metres were sandstone layers of moderate to good reservoir quality.

 

Sandstone layers totalling 36 metres with moderate to good reservoir quality were also encountered in the Nordmela, Tubåen, and Fruholmen formations from the Early Jurassic to Late Triassic, but these are water-filled. Gas-oil contact and oil-water contact were encountered at 1,865 metres and 1,876 metres below sea level, respectively.

 

The well was not formation-tested, but extensive data acquisition and sampling have been performed. The well has been permanently plugged.

 

Vår Energi is operator at PL 901 (50%) with partners Equinor Energy AS (10%), Longboat Energy Norge AS (20%), and Concedo AS (20%).
