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.
