Odin gas field

Last updated

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.

The Forties pipeline system (FPS) is a major pipeline transport network in the North Sea. It is owned and operated by Ineos and carries 30% of the UK's oil, or about 550 thousand barrels per day of oil per day, to shore. It carries liquids production from 85 fields in the North Sea and several Norwegian fields on behalf of around 40 companies. The system has a capacity of 575,000 barrels of oil a day.

<span class="mw-page-title-main">Oil and gas industry in the United Kingdom</span>

The oil and gas industry plays a central role in the economy of the United Kingdom. Oil and gas account for more than three-quarters of the UK's total primary energy needs. Oil provides 97 per cent of the fuel for transport, and gas is a key fuel for heating and electricity generation. Transport, heating and electricity each account for about one-third of the UK's primary energy needs. Oil and gas are also major feedstocks for the petrochemicals industries producing pharmaceuticals, plastics, cosmetics and domestic appliances.
