North Sea oil and gas production demonstrated improved cost efficiency last year, with spending per barrel decreasing by 9% compared to 2024, according to the latest report from the North Sea Transition Authority (NSTA).
The newly published UKCS Unit Operating Cost in 2025 report reveals positive financial trends for offshore operations, utilising comprehensive data provided directly by operators through the UK Stewardship Survey and the Petroleum Production Reporting System. In the previous year of 2024, the average Unit Operating Cost (UOC) stood at £19.66 per barrel of oil equivalent.
The substantial 9% drop observed throughout 2025 highlights the basin's continued focus on operational efficiency, leaner operations, and effective cost management.
This reduction in spending per barrel underscores the ongoing efforts by operators to optimize their production processes and maximize economic recovery across the UK Continental Shelf.
By successfully driving down operating costs, the offshore industry is not only enhancing its immediate financial resilience but is also supporting the broader strategic goals of national energy security and robust supply chain job creation as the sector continues to navigate the complex energy transition.
