The first oil has been obtained from the UK’s North Sea Mariner field – a reserve which is expected to provide more than 300 million barrels over the next 30 years.

Mariner, operated by Equinor and partners, is expected to produce annual average rates of around 55,000 barrels of oil per day and up to 70,000 barrels of oil per day at peak production.

“The start-up of Mariner, the first Equinor-operated oil field on the UKCS, establishes our foothold in the UK and reinforces our commitment to be a long-term energy partner,” says Hedda Felin, senior vice president for UK and Ireland Offshore in Equinor.

Mariner is one of the largest industrial projects in the UK in recent years. With an investment of more than $7.7 billion, the development will support more than 700 long term jobs. Contracts worth more than $1.3 billion have been awarded to UK suppliers since the project started.

Anders Opedal, executive vice president for technology, projects and drilling for the company says: “By gathering and interpreting new seismic data we have improved our understanding of the reservoirs. This has resulted in fewer and better placed wells and increased resources since the project was sanctioned in 2012.

“With the significant volumes in place, we see clear potential to further increase the oil recovery from the Mariner field and will proactively seek opportunities to do so through the application of new technology, additional drilling and future tie back opportunities.

“With the start-up of Mariner, we have delivered one of the most complex developments in the North Sea and Equinor’s portfolio. We will continue to apply digital solutions and new technology to deliver safe and efficient operations and optimise production.”
