By Ben Ward, Market Intelligence Manager, OEUKThe North Sea Transition Authority’s (NSTA) March 2025 revision to the UK Continental Shelf (UKCS) production projections indicates a further downward adjustment. Between the February 2023 and March 2025 projections we have seen a reduction of 135.3 million tonnes of oil equivalent (mtoe) for the period 2025-2050. OEUK estimates that by 2030, up to 80% of UK oil and gas demand could be met by imports. To mitigate the economic and industrial impact of declining production, OEUK recommends fiscal reform by 2026, acceleration of electrification, support for domestic production, and infrastructure longevity planning. These figures can be found in OEUK’s “Impact of UKCS Fiscal Policy on UK Economic Growth 2025” paper.
