The NPD announces oil and gas discovery east of Johan Castberg

Well 7220/6-2 R is a deepening of well 7220/6-2, which was temporarily plugged and abandoned in November 2015. The well was drilled about 60 km northeast of the oil and gas discovery 7220/11-1 (Alta) and about 20 km east of 7220/8-1 Johan Castberg.

The primary targets for the well were to prove petroleum in Middle Triassic sandstone rocks (Snadd formation) and in Permian to Carboniferous carbonate rocks (Ørn formation).

The well encountered a total oil column of about 20 m with an overlying gas column of about 10 m in carbonate rocks in the Ørn formation, with good to moderate reservoir properties. In the Snadd formation, the well encountered aquiferous sandstone with moderate to good reservoir properties.

Recoverable oil

Preliminary estimations of the size of the discovery range between 3 and 7 million m³ of recoverable oil and between 1 and 2 billion m³ of recoverable gas.

The well was not production tested, but extensive data acquisition and sampling were carried out.

The well is the sixth exploration well in production licence 609. The licence was awarded in the 21st licensing round in 2011.

The well was drilled to a vertical depth of 1293 m below the sea surface, and was terminated in basement rocks. Water depth is 387 m. The well will now be permanently plugged and abandoned.

Well 7220/6-2 R was drilled by the Leiv Eiriksson drilling facility, which will now proceed to production licence 533 in the Barents Sea to drill wildcat well 7219/12-1 where Lundin Norway AS is the operator.
