ConocoPhillips Skandinavia and its partners have submitted a plan for development and operation (PDO) for the Tommeliten A field in the North Sea.

The PDO for the project, which straddles the Norway-UK median line in the North Sea, has been submitted to the Norwegian Ministry of Petroleum and Energy and the UK Oil and Gas Authority.

The project is estimated to cost around Nkr13bn ($1.5bn) for development, with first production planned in 2024.

It is planned to be developed using a two-by-six slot subsea production system (SPS), which will be tied back to the Ekofisk platform located around 25km away.

ConocoPhillips Europe, Middle East and North Africa president Steinar Våge said: “We are pleased to achieve this milestone for the Tommeliten A project.

“The field development will unlock production of new resources in the area and further strengthen the Ekofisk legacy and future.”

According to estimates, the Tommeliten A field holds resources ranging from 80-180 million barrels oil equivalent, mainly comprising gas condensate.

ConocoPhillips Skandinavia operates the Tommeliten A Unit with a 28.1385% stake.

Other partners include PGNiG Upstream Norway (42.1978%), TotalEnergies EP Norge (20.1430%), Vår Energi (9.0907%), ConocoPhillips (UK) (0.2109%), TotalEnergies UK (0.1510%) and ENI UK (0.0681%).

Discovered in 1977, the UK-Norway trans-boundary field extends from Norwegian Block 1/9 into UK Block 30/20. It is being developed as a Norwegian project.

The partners plan to award several contracts during the project period. These contracts are expected to create approximately 5,000 jobs.

In September 2021, ConocoPhillips Skandinavia awarded a contract to Aker Solutions for modifications on the Ekofisk installations to integrate the Tommeliten Alpha discovery offshore Norway.
