UKCS Offshore Wellbore Top Hole Locations with Geospatial Coordinates

Wellbore data for the UK Continental Shelf, managed by the North Sea Transition Authority (NSTA). The dataset includes top hole locations, representing the surface or seabed entry point for offshore drilling operations. Data collection begins once a well is spudded and operators submit notifications via the Wells Operations Notification System (WONS).

Use Cases

• Map offshore drilling activity based on well origin locations mentioned in the description.
• Analyze spatial distribution of oil and gas exploration based on wellbore data.
• Support regulatory compliance and oversight based on data submitted via the WONS system.
• Integrate with subsurface models using the defined wellbore and bottom hole locations.

Strengths

• Data is provided in multiple geospatial formats (GEOJSON, KML, GPKG) for interoperability.
• Dataset is maintained by the authoritative regulatory body, the North Sea Transition Authority.
• Wellbore definitions are formally referenced to the PPDM (Professional Petroleum Data Management) standard.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
