First production from Maersk Oil's Flyndre field, which straddles the UK and Norwegian North Sea boundaries, started yesterday (26 March).
The field is a 25km single well subsea tieback to the Repsol Sinopec-operated Clyde platform, from which it is then exported via the Fulmar platform, also operated by Repsol, then on to Teesside via the Norpipe system.
Repsol says that adding Flyndre to Clyde's production would help extend the life of the Clyde facility "well into the next decade."
Production from the Flyndre field is expected to peak at around 10,000 b/d with the field expected to produce until at least 2023.
Flyndre was discovered in 1974 and is about 293km south east of Aberdeen in UK blocks 30/13 and 30/14 and 325km west south-west of Stavanger in Norwegian block 1/5 (PL018C).
Partners in the Flyndre field development are Maersk Oil UK (65.941%), Repsol Sinopec Resources UK (22.739%), Repsol Sinopec North Sea (4.24%), Maersk Oil Norway (6.255%), Statoil Petroleum (0.471%) and Petoro (0.354%).
Maersk Oil says it also continues to work on its high-pressure, high-temperature Culzean field development, in the UK North Sea. The firm also has a stake the giant Statoil-operated Johan Sverdrup development, offshore Norway.
Repsol is also working towards first oil from its Montrose Area Redevlopment, which it says is imminent.
