UKCS Offshore Wellbore Top Hole Locations (ED50)

Wellbore top hole location data from the UK Continental Shelf, managed by the North Sea Transition Authority. Data collection begins once a well is spudded and operators submit notifications via the Wells Operations Notification System (WONS). The dataset includes multiple file formats such as GeoJSON, KML, and GPKG for geospatial analysis.

Use Cases

• Mapping offshore drilling activity based on well origin locations.
• Analyzing spatial distribution of wells for resource planning.
• Integrating wellbore paths with other geospatial datasets for subsurface modeling.
• Verifying regulatory compliance for well drilling and data submission as per Petroleum Operations Notices (PON) 9.

Strengths

• Data is provided in multiple geospatial formats including GeoJSON, KML, and GPKG.
• Managed by the authoritative regulatory body, the North Sea Transition Authority.
• Well locations are defined according to the PPDM 'what is a well' standard.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-06-18 11:12:39.649792.
