Stepping into Downing Street as Prime Minister, Andy Burnham knew he faced a defining test of his premiership. On his desk sat a vital Treasury report. It argued that unlocking the Jackdaw and Rosebank North Sea fields would provide crucial tax revenues for the nation.
Looking out the window toward Westminster, he considered his next move. To him, the choice was clear: supporting existing licenses. It wasn't just about securing the £18bn needed for defense; it was about protecting the livelihoods of families in Aberdeen and keeping the lights on in Manchester.
Burnham picked up his pen. The critics, including the Green Party, would shout loudly, but he was convinced this pragmatic compromise was the right call for Britain’s energy security.
Prime Minister Andy Burnham is expected to back the development of existing North Sea oil and gas fields. Having just taken office on July 20, 2026, reports confirm his team has directed the civil service to draw up plans to progress controversial drilling projects.
How He Plans to Support It
Approving Existing Sites: Burnham is shifting policy focus toward backing production at major, already-licensed fields like Rosebank and Jackdaw.
Expanding "Tie-Backs": His strategy relies heavily on expanding tie-backs—connecting new drilling areas to pre-existing pipeline infrastructure.
Upholding the Manifesto Wording: By fast-tracking existing licenses and utilizing tie-backs, Burnham can increase domestic drilling without technically breaking Labour's 2024 manifesto pledge to ban completely new exploration licenses.
The Political Context
Deputy Leader Lucy Powell described this move as a "change of emphasis" and a pragmatic approach to securing domestic energy supply amidst geopolitical instability. While the decision has already triggered major protests from environmental groups and climate campaigners, it has been welcomed by trade unions and international figures like U.S. President Donald Trump.
Prime Minister Andy Burnham is backing North Sea oil drilling, including Rosebank and Jackdaw, to boost energy security and satisfy key union factions. While framed as a pragmatic cost-of-living strategy, this move risks environmental backlash and conflicts with independent analyses suggesting it will not lower household bills.
Evaluating the Jackdaw and Rosebank fields requires looking at their physical capacity alongside the overall "flaccidity"—or rapid natural decline—of the North Sea region's production.
The physical size, specific outputs, and local dynamics of both projects break down as follows:
1. Rosebank Field (The UK's Largest Untapped Asset)
Total Estimated Reserves: Over 480 million to 500 million barrels of oil equivalent (boe).
Resource Breakdown: Composed of roughly 90% oil and 10% gas.
Production Volume: At its peak, Rosebank is projected to produce around 70,000 barrels of oil and 21 million cubic feet of natural gas per day.
Regional Significance: Located 80 miles west of the Shetland Islands, it is a complex deepwater project sitting over 1km below the surface in harsh Atlantic conditions.
2. Jackdaw Field (The Ultra-Acidic Gas Reserve)
Total Estimated Reserves: Roughly 120 million to 250 million barrels of oil equivalent (primarily natural gas).
Resource Breakdown: Dominated by high-pressure, high-temperature natural gas, with a smaller volume of light oil condensates.
Production Volume: It is estimated to provide enough natural gas to heat over 1.4 million UK homes at peak capacity.
Regional Significance: Located in the Central North Sea, it is a "tie-back" project designed to route gas back to Shell's existing Shearwater platform infrastructure.
The Reality of North Sea "Flaccidity" (Regional Decline)
The core argument driving Prime Minister Burnham's pragmatic support is to cushion a steep, ongoing collapse in domestic production.

The Decline Curve: UK oil output has nearly halved since 2020. Without projects like Rosebank and Jackdaw, the UK infrastructure risks a sudden shutdown as older rigs become uneconomical to operate.

The "Tie-Back" Strategy: Jackdaw and parts of Rosebank rely on utilizing pre-existing platforms and pipelines. Proponents argue that using new fields to prop up old infrastructure keeps the UK energy network viable while the country builds out wind and carbon capture alternatives.
The Economic Vulnerability: Because North Sea production is declining so fast, critics and independent analyses note that even the massive scale of Rosebank and Jackdaw will not change global market prices. Most of Rosebank's oil will be traded on international markets rather than directly lowering domestic UK energy bills.
Apparently compared to Venezuela Orinoco basin and gulf of Mexico,gulf of guinea and Siberian provinces of Russia and middle east how competitive that is is debatable
Evaluating the global competitiveness of the North Sea (and projects like Jackdaw and Rosebank) against giant oil provinces reveals a stark reality: on an international scale, the North Sea is a marginal, high-cost player, making its true financial competitiveness highly debatable.
While the North Sea boasts high-quality Brent crude and strong rule of law, it cannot compete with the sheer volume or the rock-bottom extraction costs of other major global hubs.
Global Energy Competitiveness Comparison
Region Size / Volume Extraction Cost per Barrel Oil/Gas Quality Main Strategic Advantage / Vulnerability
North Sea (UK) Small / Mature
(Rosebank: ~500M boe total) High
(~$30–$40+) Premium Light, Sweet (Brent) & Gas Advantage: Low geopolitical risk, local demand.
Vulnerability: Rapid natural decline.
Middle East (e.g., Saudi Arabia) Massive / Dominant
(~267B barrels) Extremely Low
(~$2–$9) Light to Medium Conventional Advantage: Lowest cost globally, infinite scaling.
Vulnerability: High geopolitical volatility.
Venezuela Orinoco Basin World's Largest
(~303B barrels) High
(Due to heavy refining costs) Extra-Heavy, High-Sulfur Advantage: Unmatched absolute volume.
Vulnerability: Requires extensive upgrading & blending.
Deepwater Gulf of Mexico Large / Active
(~7B+ boe remaining) Medium-High
(~$25–$35) Light to Heavy Blend Advantage: Rapid tech innovation, close to US refineries.
Vulnerability: Hurricane risk, strict regulations.
Gulf of Guinea (e.g., Nigeria) Large / Under-explored
(~37B barrels) Medium
(~$20–$30) High-Quality Sweet Crude Advantage: Highly desired by Western refineries.
Vulnerability: Crude theft, political instability, under-investment.
Siberian Provinces (Russia) Massive
(~80B barrels) Low-Medium
(~$15–$25) Heavy/Medium (Urals) Advantage: Massive onshore infrastructure.
Vulnerability: Heavy Western sanctions, harsh logistics.
Key Analytical Takeaways: The Competitiveness Debate
1. Volume and Economies of Scale
The combined total reserves of Jackdaw and Rosebank (~750 million barrels of oil equivalent) are a literal drop in the bucket compared to the Orinoco Basin's 303 billion barrels or a single "super-giant" field in the Middle East. Because the North Sea fields are small and fragmented, operators cannot achieve the same massive economies of scale found in Siberia or Saudi Arabia.
2. Fiscal and Capital Inefficiency
The North Sea is an expensive place to operate. Drilling a deepwater well west of Shetland (Rosebank) or managing high-pressure, ultra-acidic gas (Jackdaw) requires immense capital expenditure.
A Middle Eastern operator can turn a profit even if global oil prices crash to $15 a barrel.
A North Sea field like Rosebank requires much higher sustained global oil prices just to break even, making it economically vulnerable to future market downturns.
3. The "Flaccidity" Factor vs. The Field Quality
While Venezuela's Orinoco Belt faces massive infrastructure deficits, its hydrocarbons are trapped in soft, easily accessible onshore sands. The North Sea is the opposite: its infrastructure is world-class, but the fields themselves are physically declining ("flaccid"). Operators are forced to spend millions trying to squeeze the last remaining pockets of oil out of a dying basin.
4. The Political Premium
The only metric where the North Sea cleanly defeats regions like the Gulf of Guinea, Russia, or the Middle East is political stability. For Prime Minister Burnham, the competitive edge isn't financial—it is geopolitical. A barrel of oil from Rosebank doesn't require navigating international sanctions, Russian warfare, or Middle Eastern blockades. It flows straight into the UK economy, which is the primary reason it is being backed despite its poor global cost-competitiveness.
