Small discovery in the Barents Sea

Equinor has found 12-25MMbo in the Skruis prospect due north of Johan Castberg.

The well was drilled about 8 kilometres north of the 7220/8-1 discovery well on the Johan Castberg oil field, and Equinor says it helps to determine the size of the Johan Castberg resource base which is currently being developed.

Recoverable reserves in Johan Castberg are estimated at between 450-650 million barrels. The volumes from Skruis and the Kayak discovery from 2017 are not included in this estimate, according to Equinor.

«Securing resources near existing infrastructure is an important part of Equinor’s ambition and strategy on the Norwegian continental shelf,» says Nick Ashton, Equinor’s senior vice president, Exploration, Norway & UK.

The Skruis discovery confirms the potential in this part of the Barents Sea. Over the past couple of years, we have learned that exploration in the Barents Sea is challenging and takes patience,” says Ashton.

The well encountered a total oil column of about 35 metres in the Stø formation, 30 metres of which was effective reservoir in sandstone with moderate to good reservoir quality.

The oil/water contact was encountered at 1415 metres below the sea surface. Both the Stø and the Nordmela formation are a little thicker than expected.

The Stø formationhas about 30 metres of water-bearing sandstone below the oil/water contact, with mainly good reservoir properties.

The Nordmela formationhas water-bearing sandstone layers totalling more than 100 metres with moderate to good reservoir quality. In the Tubåen formation, the sandstone layers have moderate to good reservoir properties.
