North Sea Oil Costs Fall by 9% Amid Pressure to Maximize Production

The North Sea oil production costs have decreased by 9% from last year, according to the latest report from the North Sea Transition Authority (NSTA). This decline in cost is attributed to improved production efficiency and the closure of older, more expensive fields. The average cost per barrel of oil equivalent fell from £19.60 in 2024 to £17.81 in 2025.

The NSTA also reported that production rates remained steady at approximately 1.1 million barrels of oil equivalent (boe) per day in both years. Loraine Pace, the NSTA's Head of Performance and Planning, emphasized the importance of operators focusing on efficiency and innovation to keep costs under control, especially with projected increases in 2026 and 2027.

As North Sea operators face pressure to maximize production from existing assets due to declining domestic oil and gas output, this cost reduction is a positive development. The report highlights that 56 reinstated wells produced an additional 16 million boe in 2025, demonstrating the growing focus on improving output from existing infrastructure.
