Oil and gas minnow Tailwind Energy is pressing ahead with a project to develop the Evelyn field in the central North Sea.
The company has handed in an environmental statement — a key step in the regulatory approvals process — to the UK department for Business, Energy and Industrial Strategy.
Tailwind, based in London, initially intends to deliver hydrocarbons from Evelyn as a single well tied back to the Triton floating production, storage and offloading vessel (FPSO), operated by Dana Petroleum.
A final investment decision is expected to be made later this year, ahead of first oil at the end of 2022.
Subsea construction work would take place in summer 2022 and last around 90 days.
Tailwind predicts Evelyn could produce for about eight years, based on the current assumption that Triton, 110 miles east of Aberdeen, will cease production in late 2030 or early 2031.
A second phase involving a new well could follow, said Tailwind, which wholly owns Evelyn.
The first phase could yield 17.4 million barrels of oil equivalent (boe), with an additional 4.4m boe targeted from the second well.
The firm added that the Belinda field could also be developed via Triton if Evelyn phase one is successful.
Evelyn was discovered by Shell in 1984 and Belinda followed in 1990.
Tailwind is backed by private commodities and energy group Mercuria.
The business was founded in 2016 by a management team boasting more than 200 years of experience in investment and exploration and production.
It is led by Stephen Edwards, whose career in oil and gas started at Schlumberger.
It completed a deal to buy Shell and ExxonMobil’s stakes in the Triton cluster in September 2018.
