Production Volume:

Skarv is located about 35 kilometres southwest of the Norne Oil Field in the northern part of the Norwegian Sea. The water depth in the area is 350 - 450 metres. There will be a joint development of the 6507/5-1 Skarv and 6507/3-3 Idun deposits. The 6507/5-3 Snadd deposit is part of Skarv, but is presently not included in the development.
The field development consists of one large production vessel; the Skarv FPSO (Floating Production, Storage and Offloading vessel), and five subsea templates with flexibility for new projects
The vessel which is close to 300 m long and 50 m wide ranks as the world’s largest gas processing vessel with a capacity of 15 million standard cubic metres of gas and 80 000 barrels of oil per day. Total storage capacity is 875 000 barrels of oil.
Gas export is via separate 80 km long gas pipeline via the Asgard Transport System to Kårstø, southern Norway

+++ Geology

The reservoirs in Skarv contain gas and condensate in Middle and Lower Jurassic sandstones in the Garn, Ile and Tilje Formations. There is also an underlying oil zone in the Skarv deposit in the Garn and Tilje Formations. The Garn Formation has good reservoir quality, while the Tilje Formation has relatively poor quality. The reservoirs are divided into several fault segments and lie at a depth of 3 300 – 3 700 metres.
