UK Oil and Gas Sector Sees Major Developments as Companies Merge and Expand

In a time of heightened energy concerns, the UK oil and gas sector is buzzing with activity, particularly with two major developments: the anticipated production from the Jackdaw gas field and the merger that formed NEO NEXT+, which is set to become the largest independent oil and gas producer on the UK Continental Shelf.

With the backdrop of an unstable geopolitical climate, particularly the conflict in Iran affecting energy prices and supply chains, the UK government is placing a renewed focus on domestic energy production. This has put projects like Jackdaw and Rosebank into the spotlight, with officials emphasizing their potential to bolster the nation's energy security.

According to Kemi Badenoch, the UK’s Secretary of State for Business and Trade, the Jackdaw gas field could start supplying gas to over a million homes by winter 2026, which would represent about six percent of the UK’s future gas supply. "We need to be ready to tap into our own resources to reduce our reliance on imports," she stated during a recent parliamentary session.

Located approximately 150 miles east of Aberdeen, the Jackdaw field is a substantial project that has already seen over £1 billion invested. This investment has supported more than 1,000 jobs and contributed over £2 billion to the UK economy. Adura, the company behind the project, was formed in December 2025 and is committed to securing energy for the UK through both traditional and renewable sources.

Neil McCulloch, Chief Executive of Adura, emphasized the importance of the Jackdaw project in the broader energy conversation: "Jackdaw will be one of the lowest carbon developments in Europe, with emissions about eight times less than imported liquefied natural gas (LNG)." This is particularly relevant as the UK seeks to balance its energy needs with its climate commitments.

Jackdaw's gas reservoir lies over 5 kilometers beneath the seabed at temperatures of 191°C and pressures of 17,000 psi—conditions that require advanced engineering expertise. McCulloch noted, "Working in harsh conditions, we apply the brightest minds in the business to bring projects like Jackdaw to fruition. We could technically start producing gas from Jackdaw as early as October 2026, which would help meet the UK's pressing energy needs this winter."

Yet, the project has not been without its challenges. In 2024, a UK Supreme Court ruling mandated that future approvals for oil and gas projects must take into account emissions produced by the end use of these resources. This ruling, along with a subsequent decision in Scotland's Court of Session in 2025, has delayed the production timeline for Jackdaw and Rosebank, requiring new environmental consents before gas can be extracted.

Meanwhile, the merger that created NEO NEXT+ marks a notable shift in the UK oil and gas sector. TotalEnergies and NEO NEXT Energy finalized their merger of upstream oil and gas assets, forming a new entity that is expected to produce over 250,000 barrels of oil equivalent per day by 2026. This merger, announced in December 2025, positions NEO NEXT+ as a formidable player in the market, with TotalEnergies holding a 47.5% stake, HitecVision at 28.875%, and Repsol UK with 23.625%.

Patrick Pouyanné, Chairman and CEO of TotalEnergies, highlighted the significance of this merger for the UK’s energy supply: "The creation of NEO NEXT+ marks an important step in TotalEnergies’ long-term commitment to the UK oil and gas sector. Our extensive operational experience in the North Sea will bring synergies and improve cash flow generation for the new company."

This merger consolidates assets and enhances operational capacity, as NEO NEXT+ will include stakes in prominent fields such as Elgin/Franklin, Mariner, and Culzean. The integration of TotalEnergies' assets is expected to improve the financial stability of NEO NEXT+, particularly as the company assumes up to $2.3 billion in decommissioning liabilities from its former assets.

As the UK navigates its energy future, the developments surrounding Jackdaw and the formation of NEO NEXT+ are emblematic of a broader push to utilize domestic resources more effectively. With oil and gas still accounting for over 70% of the country’s energy demand, these projects are not just about meeting current needs but also about ensuring a sustainable energy strategy for the future.

The importance of these initiatives cannot be overstated, especially as the UK grapples with external pressures on its energy supply and the pressing need to transition to greener alternatives. As McCulloch pointed out, "The relevant question is where we choose to get our energy from. Half of our gas supply comes from British waters, and every molecule of that resource is used in this country. The other half comes from imports, which often come with higher emissions."

In light of these developments, the UK’s energy security is a national concern that should resonate with all citizens. With both Adura and NEO NEXT+ playing key roles in this sector, the focus will be on how quickly they can bring their projects online and what impact that will have on the UK’s energy independence and environmental goals.

As we head into the winter months, the urgency for reliable energy sources is more pronounced than ever. The government, industry leaders, and the public must remain engaged in discussions around energy policy, regulatory processes, and the balance between fossil fuel reliance and the transition to renewable energy sources. The stakes are high, and the outcomes of these projects could very well shape the future of the UK’s energy narrative for years to come.
