Lundin Norway AS has made an oil and natural gas discovery in the southern Barents Sea after deepening a well that had been plugged in November 2015.
The 7220-/6-2 R well, also known as Neiden, encountered a total oil column of 20 m with an overlying gas column of about 10 m in Permian-to-Carboniferous carbonate rocks in the Orn formation. Another primary target was the Snadd formation in Middle Triassic sandstone.
The well was drilled by Ocean Rig’s Leiv Eiriksson semisubmersible drilling rig to a vertical depth of 1,293 m subsea in 387 m of water in PL 609. It was not production tested.
Lundin Petroleum AB said the total gross resource estimate is 25-60 million boe. Partner DEA Norge AS said the preliminary estimate is 19-44 million bbl of oil recoverable and 1-2 billion cu m of gas recoverable. For the oil estimate, the Norwegian Petroleum Directorate used 3-7 million cu m.
Lundin has 40%, DEA Norge 30%, and Idemitsu Petroleum Norge AS 30%.
The well is 60 km northeast of the 7220/11-1 Alta discovery and 20 km east of the 7220/8-1 Johan Castberg. It’s also about 2 km northwest of exploration well 7220/6-1, Obelix, drilled in 2005.
The Leiv Eiriksson will next drill wildcat 7219/12-1, the Filicudi prospect, for Lundin in PL 533.
