Maersk Oil has announced the start of production from Flyndre field in the UK and Norwegian North Sea.
The first oil produced flowed through the 25km pipeline to the Repsol Sinopec-operated Clyde platform.
At its peak, the project is expected to produce approximately 10,000bpd and the field is expected to continue production until 2023.
Maersk Oil CEO Gretchen Watkins said: "Flyndre first oil represents new production for both the UK and Norway and we’re pleased to have worked with partners on both sides of the border to deliver this development."
The Flyndre field is nearly 293km south-east of Aberdeen in blocks 30/13 and 30/14 of the UK North Sea and 325km south-west of Stavanger in block 1/5 (PL018C) of the Norwegian North Sea.
The project was discovered in 1974 and straddles between the UK/Norway median line. It is developed as a subsea tie-back to the Clyde platform with a single production well.
The transport route procures oil from the Clyde platform through the Repsol Sinopec-operated Fulmar platform towards Teesside via the Norpipe system.
Watkins added: “By combining experience and strong technical capabilities Maersk Oil is helping engineer a bright future across the North Sea, and bringing new developments on stream is always a strong signifier of that.”
Maersk Oil UK Limited holds 65.941% stake in the Flyndre field.
Other participants in this project are Repsol Sinopec Resources UK Limited with 22.739% stake, Repsol Sinopec North Sea Limited with 4.24% interest, Maersk Oil Norway AS with 6.255% stake, Statoil Petroleum AS with 0.471% interest and Petoro AS with 0.354% stake.
