NSTA Licences: UK Oil and Gas Exploration and Production Areas

The North Sea Transition Authority's licensing system defines exclusive rights for petroleum prospecting, exploration, and extraction across Great Britain and the UK Continental Shelf. Licence data is represented by three different datasets covering whole licences, licensed blocks, and sub-areas, with polygons in the WGS84 coordinate system. The data was last updated on 2025-09-11 by the Government Digital Service.

Use Cases

• Map petroleum resource exploration zones based on the described licence polygons.
• Analyze the distribution of offshore versus onshore licences as mentioned in the description.
• Study the administrative subdivision of licences into blocks and sub-areas for operational analysis.
• Model the economic geography of UK oil and gas recovery based on the licensing framework.

Strengths

• Data is structured into three distinct geospatial datasets (Licences, Licence Blocks, Sub Areas) for different levels of analysis.
• Polygons use the standard WGS84 coordinate reference system.
• Explicitly distinguishes between onshore and offshore licences and between exploration and production licences.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and institutional bias inherent to the UK's regulatory framework.
