The UK North Sea is a mature basin, but the pace of decline is determined by policy, not geology, argues Jon Fitzpatrick, Founder and President of Gneiss Energy.

BP’s decision to sell its UK North Sea business should be viewed as more than a portfolio management exercise. It is a reminder of a broader challenge facing the UK Continental Shelf: not whether decline is occurring, but whether it is being accelerated by policy choices.
Nobody disputes the maturity of the UKCS. Production has been falling for years, infrastructure is ageing and the era of giant discoveries is long behind us. The debate is not about returning to historic peak output. It is about whether the UK is managing the basin’s remaining potential in a way that maximises economic value, energy security and transition outcomes.
The answer increasingly appears to be no.
Today Gneiss Energy has published a white paper ‘One basin, two outcomes’ which compares Norway’s approach with our own.
The comparison is instructive. Both countries share the same geological province and both have moved through the natural lifecycle of a mature offshore basin. Yet over the past decade their trajectories have diverged markedly.
Norway has continued to sanction projects, issue licences and sustain production at levels that have repeatedly outperformed expectations. The UK, meanwhile, has experienced a sharper decline and a growing perception that long-term investment is unwelcome.
Geology explains some of this difference, but not all of it. Norwegian fields are often larger and younger, and the country undoubtedly benefits from a stronger resource base. However, Norway’s success is also the result of something more fundamental: policy consistency.
Stability counts
Too much of the UK debate focuses on headline tax rates. While comparisons with Norway are common, they often miss the point. Investors are not concerned solely with the tax rate they face today. They are concerned with the stability and predictability of the framework they will face over the life of an asset.
This is where the UK has struggled.
Since 2022, operators have faced repeated fiscal interventions, changes to allowances, revisions to investment incentives and continuing uncertainty about the future regime. Whatever view one takes on the merits of individual measures, the cumulative effect has been clear: investors see a sector where the rules can change rapidly and where long-term planning has become increasingly difficult.
Capital responds predictably to that kind of uncertainty. It moves to jurisdictions offering greater stability, clearer policy signals and more confidence in future returns.
BP’s decision should therefore be read in that context. The company has framed the move as part of a broader capital allocation strategy, prioritising opportunities that offer stronger long-term returns.
The important question is why the UK is finding it increasingly difficult to compete for that capital in the first place.
Continued dependence
The irony is that this is happening at a time when the UK will remain heavily dependent on oil and gas for decades. Even under ambitious decarbonisation scenarios, hydrocarbons continue to play a significant role in the energy mix throughout the transition period.
The issue is therefore not whether demand exists. The issue is where supply comes from.
If domestic production declines faster than demand, imports fill the gap. That may satisfy consumption requirements, but it does little for energy security, domestic employment, tax revenues or supply-chain resilience. It also raises difficult questions about emissions, particularly when imported LNG carries a higher lifecycle carbon footprint than domestically produced alternatives.
Recent geopolitical events have reinforced the importance of these considerations. Governments across Europe have been reminded of the risks associated with overreliance on external supply.
Yet the UK continues to allow the economics of domestic production to deteriorate while accepting a growing dependence on imports.
This is not an argument against net zero. Nor is it a case for ignoring the realities of a declining basin. It is simply an argument for realism.
A managed transition
A credible transition requires three things to be recognised. First, the UK must continue to decarbonise. Second, the transition cannot immediately eliminate the UK’s reliance on oil and gas. Third, where it can be developed responsibly and competitively, domestic production is preferable to importing hydrocarbons from overseas.
The UKCS still contains significant value. Undeveloped discoveries, tie-back opportunities and infrastructure-led developments could contribute meaningful production if the right investment conditions exist.
However, these opportunities are highly time sensitive. Once infrastructure is removed, nearby resources can become stranded. Once supply-chain capability is lost, it is difficult to rebuild. Once experienced personnel leave the sector, those skills do not readily return.
The lesson from Norway is not that decline can be avoided forever. It cannot. The lesson is that mature basins perform best when governments provide stable fiscal frameworks, efficient regulatory processes and a clear long-term commitment to responsible resource development.
The UK still has time to pursue that approach, but the window is narrowing. A permanent and competitive fiscal regime, timely approvals for commercially viable projects and a clear recognition that domestic production has a role within the energy transition would all help restore confidence.
If Britain is going to rely on oil and gas for decades to come, it should have the confidence to produce as much of that energy as possible from its own basin, using its own workforce, under its own environmental and regulatory standards.
The alternative is not a faster transition. It is simply greater dependence on imports.
