UKCS Offshore Hydrocarbon Field Outlines in WGS84

UK Continental Shelf offshore hydrocarbon field outlines provided by operators at the point of field determination or re-determination. The dataset is maintained by the North Sea Transition Authority and was last updated on 2026-06-18. It includes fields defined as single geological petroleum structures encompassing the maximum extent of hydrocarbons based on geological criteria.

Use Cases

• Map the spatial distribution of offshore hydrocarbon resources based on field outlines.
• Analyze the geological extent of petroleum structures based on operator-provided determinations.
• Integrate field boundary data with other geospatial layers for energy infrastructure planning.
• Monitor changes in field definitions over time based on re-determination events.

Strengths

• Field outlines are provided directly by operators, suggesting authoritative source data.
• Data is available in multiple geospatial formats including GEOJSON, KML, and GPKG.
• The dataset was updated on 2026-06-18, indicating recent maintenance.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description does not specify the temporal coverage of the field determinations.
