Zennor Petroleum will go ahead with the Finlaggan field development after the UK oil regulator approved its plans.
Finlaggan is expected to pump out 26 million barrels of oil equivalent (boe) with start-up slated for the fourth quarter of 2020.
The field will produce from two subsea wells tied back to ConocoPhillips’ Britannia platform in the central North Sea.
Zennor recently agreed to buy an 8.97% working interest in the Britannia field from Mitsui E&P UK.
The Finlaggan development wells are currently being drilled by Transocean’s Paul B Loyd Junior drilling rig.
The first of the two development wells has been successfully drilled.
The subsea construction contract has been awarded to TechnipFMC, with the main installation works planned for 2019.
Meanwhile, Zennor has secured a £170 million loan facility to fund the project from a number of lenders.
Zennor managing director Martin Rowe said: “This year has been transformational for Zennor. We recently announced the strategic acquisition of an 8.97% working interest in the Britannia Field, subject to partner and regulatory approval, which has doubled our production to circa 5,000 boe per day.
“Today, we are fully financed to take Finlaggan through to first production in 2020.
“We greatly appreciate the support we have received from the Oil and Gas Authority (OGA), our banking syndicate and our key contractors and partners in enabling us to push forward with the execution of the Finlaggan project; a key foundation stone of our growing portfolio.”
Scott Robertson, central North Sea area manager at the OGA, said: “We are pleased to approve the Finlaggan field development. The gas field, which was discovered 13 years ago, will tie-back to the Britannia facilities, utilising existing infrastructure, maximising economic recovery from the region.”
