25/2-10 S (Frigg-GammaDelta) is a discovery in the central North Sea, 20 kilometres east of the Frigg field. The water depth in the area is 120 metres. The discovery was proven in 1986 on the Frigg Gamma structure. The reservoir contains oil and gas in sandstone of Eocene age in the Frigg Formation, at a depth of 1,900 metres. The resources also include the Frigg Delta structure, where well 25/2-17 proved oil at the same reservoir level in 2009. Various development solutions are being evaluated for Frigg-GammaDelta, which is being considered as a part of a bigger development in the area between the Oseberg and Alvheim fields.
