NSTA and Lloyd's Register UKCS Merged Regional Geological Maps

Public domain geological maps for the UK Continental Shelf, including depth structure, isochore, and facies maps for intervals like the Paleocene and Upper Jurassic. The project integrates data from sources like the 21CXRM Palaeozoic project, the Southern Permian Basin Atlas, and university research. Products are available via ARCGIS GEOSERVICES REST API and HTML formats.

Use Cases

• Modeling subsurface depth structure based on depth structure maps for main geological intervals.
• Analyzing sediment distribution and reservoir potential based on depositional facies and reservoir distribution maps.
• Planning well placement and assessing geological risk based on well penetration and structural elements maps.
• Conducting regional stratigraphic correlation based on isochore maps for intervals like the Danian and Selandian.

Strengths

• Integrates multiple third-party data sources including university seismic interpretations and public domain projects.
• Maps cover specific geological intervals such as Paleocene, Lower Cretaceous, and Upper Jurassic.
• Data is released as public domain, facilitating open use.

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.
• Freshness should be verified as the last update is listed as 2026-06-18.
