NPD announced that Wintershall DEA Norge AS, operator of production licence 211, has concluded the drilling of wildcat well 6507/4-2 S. The well was drilled about 12 kilometres north of the Dvalin field in the Norwegian Sea, and 270 kilometres north of Kristiansund. The well's primary exploration target was to prove petroleum in Middle Jurassic reservoir rocks (the Garn Formation). The secondary exploration target was to prove petroleum in two reservoir levels from the Late Cretaceous, in the Lysing and Lange formations. The well encountered a gas column totalling 85 metres in the Garn Formation, of which about 60 metres consist of sandstone of moderate to poor reservoir quality. The gas/water contact was not encountered. The preliminary calculation of the size of the discovery in the Garn Formation is between 5 and 11 million standard cubic metres (Sm3) of recoverable oil equivalent.

In the first secondary exploration target in the Cretaceous, the well encountered a 33-metre gas/condensate column in the upper part of the Lysing Formation, containing multiple sandstone layers totalling about 15 metres with moderate to good reservoir properties. The gas/water contact was proven at 2,883 metres below sea level. The preliminary calculation of the size of the discovery in the Lysing Formation is between 3 and 5 million standard cubic metres (Sm3) of recoverable oil equivalent.

In the second secondary exploration target in the Cretaceous, the well encountered four petroleum-bearing sandstone intervals in the Lange Formation. The two highest intervals have gas columns of 24 and 48 metres, respectively, containing sandstone layers totalling 9 and 11 metres, respectively, with moderate reservoir properties. No gas/water contacts were proven.

The two bottom sandstone intervals have oil columns of 23 and 19 metres, respectively, containing sandstone layers totalling 8 metres in each interval, with poor reservoir properties. No oil/water contacts were proven. The preliminary calculation of the size of the discovery in the Lange Formation is between 3 and 9 million standard cubic metres (Sm3) of recoverable oil equivalent.

The licensees will consider tying the discoveries into existing infrastructure in the area.

Well 6507/4-2 S was drilled by the Deep Sea Aberdeen drilling facility, which is now headed for wildcat well 6406/3-10 to test the oil discovery (Bergknapp) from 2020 in production licence 836 S in the Norwegian Sea, where Wintershall DEA Norge AS is the operator.
