Frigg was one of the first discoveries on the Norwegian Continental Shelf. It straddles the median line between the British and Norwegian sectors of the North Sea.
Since it went online in September 1977, the field produced 192 billion cubic meters of natural gas, worth an estimated US$31.1 billion.
Total said several times it had postponed plans to close the field because "good methods for draining the reservoir, combined with cost-effectiveness and efficient organizational solutions, have contributed to extending the production."
