NSTA and Lloyd's Register UKCS Merged Regional Geological Maps

Public domain geological maps for the UK Continental Shelf, informed by multiple third-party data sources including the 21CXRM Palaeozoic project and the Southern Permian Basin Atlas. The project produced depth structure maps for main geological intervals like the Paleocene and Lower Cretaceous, and more detailed depositional facies maps for stratigraphic intervals such as the Danian and Selandian. The dataset is provided via ArcGIS GeoService and was last updated on 2026-06-18.

Use Cases

• Model basin evolution based on interpreted depth structure maps for geological time intervals.
• Assess reservoir distribution based on depositional facies maps for specific stratigraphic intervals.
• Integrate regional geological interpretations with proprietary data using the public domain maps.
• Study the structural elements of the North Sea based on the merged regional map products.

Strengths

• Merges data from multiple authoritative sources including the British Geological Survey's Offshore Geoindex and university research projects.
• Includes interpreted products like depth structure maps and depositional facies maps derived from the source data.
• Covers a high-level, regional scope of the UK Continental Shelf.

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 as the last update timestamp is in the future (2026-06-18).
