(Commonwealth_Europe) The UK could be sitting on far more untapped oil and gas than previously believed, according to a new independent analysis commissioned by Offshore Energies UK (OEUK) and carried out by Westwood Global Energy Group. The study suggests there may be as much as 7.5 billion barrels still left in the North Sea—over 3 billion more than what the current government estimates reflect.
This new understanding points to a major opening. If the UK taps into this extra volume, it could produce about £165 billion in economic value. And if half of the nation’s oil and gas requirements were satisfied from national sources rather than depending on imports, that worth could rise to £385 billion. That would mean more money flowing into public services, stronger job security for thousands of workers, and a boost to long-term investment.
There’s also a climate reality to consider. Even if the UK hits all its net-zero goals on time, the Climate Change Committee—an independent advisory body to the government—has acknowledged there will still be a need for oil and gas. Yet other projections are more conservative, forecasting less than four billion barrels of North Sea production in the years ahead, enough to meet less than a third of what the UK is expected to need.
OEUK is raising concerns about the potential consequences if the government fails to take action. Without continued investment and supportive policies, the domestic oil and gas industry could shrink rapidly, leaving the country dependent on imports for up to 80% of its energy needs within the next ten years. The group is calling for a continuation of licensing rounds and a rethink of the windfall tax, warning that current policy could lead to a production drop to just 2.6 billion barrels, not because the resources aren’t there, but because of political decisions.
David Whitehouse, OEUK’s chief executive, emphasized that the issue isn’t about choosing between oil and gas or renewables. This is not completely about oil and gas as against wind, he said. It’s about whether we prefer domestic oil and gas over imports. The UK is at an amazing 40% of imported energy, with strategic decisions—not geology—driving an augmented decay in North Sea production.
The statement’s results will take the middle stage at OEUK’s yearly conference in Aberdeen, which also symbolizes the 50th anniversary of North Sea oil and gas production. Whitehouse added, In a progressively unstable world, if we act now, the UK can meet more of its oil, gas, and renewables requirements from homegrown resources—we need it all.
The consequences are significant. Unlocking this potential could help secure reliable energy, reduce emissions, support 200,000 jobs, and bring in valuable tax revenue. The path forward will depend heavily on the choices made by policymakers in the months to come.
