Odin gas field
The Odin gas field was a gas producing field in the Norwegian sector of the central North Sea. Production of gas started in October 1984, the peak gas production of 360 mmcfd (million cubic feet per day) was achieved in 1985. Production ceased in 1994 and the field installation was dismantled in 1997.

[edit]The design production capacity of Odin was 10.2 million standard cubic metres per day of gas.[3]
The gas production profile of the Odin field was as shown.[1]

Odin ceased production in 1994 and the installation was removed from the field in 1997.[1]
The field may be redeveloped if the Yggdrasil area development is approved.[1]
