A North Sea oil field is celebrating production of more than three billion barrels since starting up 50 years ago.
ConocoPhillips said the Ekofisk reservoir, which started production in 1971, hit the milestone in the Autumn.
During that timeframe the Greater Ekofisk Area, comprised of eight fields, has since hit total production of six billion barrels of oil equivalent in the Norwegian North Sea.
Jan-Arne Johansen, ConocoPhillips general manager for operated assets Europe, said: “Over five decades, Ekofisk has been developed and maintained by thousands of committed employees and contractors.
“Through continued innovation and teamwork, we continue to build our business for the long-term.”
ConocoPhillips said the asset has generated billions of pounds of value during that time, including significant taxes and fees to the Norwegian government.
Around 3,000 people work on the Ekofisk installations, rigs and vessels, while around 1,000 employees and contractors work offshore at any given time.
There are also around 900 employees working onshore to support operations.
Meanwhile, Var Energi is celebrating a milestone from Goliat, a far younger field in the Barents Sea.
The firm said 100million barrels have now been produced from the asset, currently the world’s most northern producing oil field.
Goliat was discovered in 2000 before approval in 2009 and and start up in March 2016.
The field has since delivered 128 shipments of Barents Sea oil to the market.
Var Energi said in a social media post: “Thank you Team Goliat – for your safe operations, dedication and strong will to win in the Barents Sea. You make us proud.”
Goliat is operated by Var Energi with a 65% interest, while the remaining 35% stake is held by partner Equinor.
