NORTH SEA OIL AND GAS LICENSING REGIME

1. Meaning and Statutory Foundation

The North Sea oil and gas licensing regime governs exploration for and production of petroleum on the UK Continental Shelf (UKCS). Its principal statutory foundation is the Petroleum Act 1998. Petroleum rights are vested in the Crown, while the North Sea Transition Authority (NSTA) has statutory power to grant licences conferring exclusive rights to search and bore for and get petroleum within defined areas.

The Energy Act 2016 established the Oil and Gas Authority as an independent regulator; it now operates under the NSTA name. Its regulatory responsibilities include petroleum licensing, field development, production and related infrastructure.

2. Seaward Production Licences

A company wishing to explore for, drill for or extract offshore petroleum generally requires a Seaward Production Licence. Applications are normally invited through competitive offshore licensing rounds. The licence does not itself give unrestricted authority immediately to drill and produce oil or gas.

Licences incorporate legally binding model clauses dealing with matters such as licence duration, work programmes, surrender, revocation and regulatory controls. Companies participating jointly in a licence share responsibility for licence obligations, with the NSTA explaining that participants have joint and several liability.

The 33rd Offshore Licensing Round, opened in October 2022, ultimately produced several tranches of licence offers during 2023–24.

3. Licensing and Subsequent Consents

Obtaining a petroleum licence is only the first regulatory stage. Separate NSTA authorisations may be necessary before drilling wells, constructing infrastructure or commencing production.

Under licence model clauses, operators require Development and Production Consent before installing relevant infrastructure and producing hydrocarbons. Separate regulatory controls also apply to flaring, venting and offshore pipelines.

Offshore operations additionally engage environmental assessment, marine regulation and offshore safety requirements. The Offshore Petroleum Licensing (Offshore Safety Directive) Regulations 2015 form part of the licensing and safety framework, while DESNZ and the Health and Safety Executive participate in the offshore major-accident regulatory system.

4. Climate Change and Energy Transition

Modern petroleum licensing must operate within the UK's broader net-zero and energy-transition framework. The NSTA states that its regulatory functions support energy security while also contributing to the statutory net-zero objective.

The position is also undergoing policy change. The Government's November 2025 North Sea Future Plan states that new licences will not be granted for new fields, while proposing mechanisms concerning areas adjacent to existing fields. The NSTA notes that legislation is expected to provide longer-term implementation and that existing legislation continues meanwhile.

5. Case Law – R (Finch) v Surrey County Council [2024] UKSC 20

Facts: Surrey County Council granted planning permission for expansion of oil production at Horse Hill. The environmental assessment considered emissions arising directly from the development but did not assess greenhouse-gas emissions generated when the extracted oil would ultimately be refined and burned.

Legal Issue: Whether the project's Environmental Impact Assessment was legally required to assess these downstream or Scope 3 emissions.

Judgment: By majority, the Supreme Court allowed the appeal. It concluded that emissions resulting from combustion of the oil were effects of the project that should have been assessed under the applicable EIA regime.

Legal Principle/Ratio Decidendi: Where extraction inevitably leads to combustion of the resulting petroleum, the resulting greenhouse-gas emissions can constitute environmental effects of the extraction project for EIA purposes.

Significance: Although Finch concerned an onshore planning permission rather than the grant of a North Sea petroleum licence itself, its reasoning is highly important for oil and gas project approvals, particularly environmental assessment of downstream climate impacts.

6. Case Law – Wider Significance of Finch

The Supreme Court expressly discussed comparable litigation concerning North Sea petroleum licensing, including Norwegian proceedings challenging licences where downstream combustion emissions had not been assessed. This demonstrates the broader legal tension between petroleum development and climate-related environmental assessment.

Importantly, Finch does not establish that every petroleum development must be refused because it produces greenhouse-gas emissions. Rather, its central requirement concerns proper assessment and disclosure of significant environmental effects before the competent authority makes its decision.

7. Regulatory Accountability

NSTA licensing decisions remain exercises of statutory power and are therefore potentially subject to judicial review. Decisions must remain within statutory authority, observe applicable procedures and comply with public-law principles. Petroleum licences also coexist with environmental, safety and marine approvals; possessing a licence does not automatically constitute permission for every operational activity.

8. Conclusion

The North Sea licensing system is therefore a multi-layered regulatory regime combining the Petroleum Act 1998, NSTA licensing, model clauses, development and production consents, environmental assessment, offshore safety controls and climate obligations. Its contemporary challenge is to regulate existing petroleum resources while UK energy law increasingly integrates net-zero objectives, environmental accountability, energy security and transition planning.
