Sweden's Lundin Petroleum has found additional oil and gas near its Alta discovery in the Norwegian Arctic, the firm and the Norwegian Petroleum Directorate said Nov. 22.

Neiden exploration well 7220/6-2R, located in PL609 northeast of the Alta discovery on the Loppa High in the southern Barents Sea, hit a gross 31-m hydrocarbon column, with 21 m of oil and 10 m gas in the Permian target, Lundin Petroleum said in a statement.

“The total gross resource estimate for the Neiden discovery is between 25 and 60 million barrels of oil equivalents,” Lundin said, which noted coring, logging and light oil and gas sampling from wireline tools was carried out.

Lundin, discovery, Arctic The discovery lowers the risk of the nearby Børselv prospect, a 2017 drilling candidate located 15 km north and up dip from the Neiden discovery.

Lundin is the operator of the well and has a 40% stake. Its partners are Japan’s Idemitsu and DEA, the oil firm controlled by Russian billionaire Mikhail Fridman, who have stakes of 30%, respectively.

The well was drilled by the Leiv Eiriksson semisubmersible, which is moving northwest to the Filicudi prospect.

“The Filicudi prospect is expected to contain Jurassic sandstone reservoir analogous to the Johan Castberg discovery,” Lundin said. “The Filicudi prospect is estimated to contain gross unrisked prospective resources of 258 MMboe.
