Spirit Energy will pump an additional £13million into a North Sea field to extend its life by another three years.
Earlier this month the company revealed the project for the York gas development at a share fare event hosted by Oil and Gas UK (OGUK).
The firm has now revealed more details of the extension scheme for the site, 21miles off the north-east Yorkshire coastline.
Spirit Energy said the move will allow it to tap into an additional 18billion cubic feet of gas from York, which achieved first production in 2013.
Without the life extension scheme, the field would have been shut-in this year.
The £13m investment will re-route York gas to the Dimlington Terminal, moving from its previous export route via the Easington Terminal.
The works, both onshore and offshore, will be phased across 2020 and 2021, including platform and control system modifications, onshore tie-ins and a well intervention.
Girish Kabra, director of Spirit Energy’s North Sea Operated Assets, said: “York has been an important part of Spirit Energy’s North Sea portfolio for eight years, so we are delighted to not only boost production from the field but also extend its life.
“Fields like York demonstrate the importance of focused late-life management to maximise the potential of as many North Sea fields as possible.”
Mr Kabra, who assumed the role of asset director with Spirit Energy while the business was preparing for cessation of production of York, added: “It is testament to the relatively low-cost value that can be realised with a commitment to collaboration.”
York has so far produced 45 billion cubic feet of gas over the last eight years.
Industry regulator, the Oil and Gas Authority (OGA) praised the move as a “good example of innovative thinking” to support the industry’s shared goal of Maximising Economic Recovery (MER).
Southern North Sea area manager Alistair Macfarlane said: “The SNS still has 3,779 bcf of reserves and examples like this provide opportunity and valuable activity for the UK supply chain as we actively adapt ourselves toward energy transition.”
