Located approximately 34 km from the North East Yorkshire coastline, York achieved first gas in 2013 and was expected to produce until 2020. The recently approved York Life Extension Project, aimed at maximising economic recovery of the field, will extend production until 2023/24 and tap into an additional 18 billion cubic feet of gas.
The works will be phased across 2020-2021 and will comprise activity both onshore and offshore; including platform and control system modifications, onshore tie-ins and a well intervention on the Y1 well.
The £13 million investment will re-route York gas to the Dimlington Gas Terminal, accessing its onshore gas compression facility, moving from its previous export route via the Easington Gas Terminal. The project extends the life of an important North Sea field which has produced 45 billion cubic feet of gas over the past eight years.
The York field was discovered in 1993 through drilling of well 47/02-1. The decision to develop the field was made in January 2011. The field was estimated to hold reserves of about 106 billion cubic feet or 3 BCM in Upper Permian Rotliegend sandstones.
Collaboration and innovation
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. This project is a great example of the industry’s and regulator’s shared objective of delivering maximised economic recovery for the UK.”
Alistair Macfarlane, SNS and EIS Area Manager with the Oil and Gas Authority said: “We welcome this final investment decision from Spirit Energy. The re-route is a good example of innovative thinking and collaboration between multiple operators to look beyond the boundaries of current configurations to extend the field life of York and Maximise Economic Recovery.
“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.”
