6407/6-6 Mikkel Sør is a discovery on Haltenbanken in the eastern part of the Norwegian Sea, eight kilometres south of the Mikkel field. The water depth is 230 metres. Mikkel Sør was proven in 2008 and includes the 6407/6-7 S discovery, proven in 2009. The Mikkel Sør reservoirs contain gas and condensate in Middle Jurassic sandstone in the Ile and Garn Formations and lie at a depth of 2100-2230 metres. The 6407/6-7 S reservoir contains gas and condensate in Upper Jurassic sandstone in the Garn Formation and lies at a depth of 2800 metres. The most likely development solution is a combined tie-back of several discoveries in the eastern part of Haltenbanken to the Åsgard B facility. The plan for development and operation (PDO) is expected to be submitted in late 2022.
