NSTA and Lloyd's Register English Channel Regional Geological Maps (ArcGIS Version)

A set of regional geological maps for the English Channel area of the UK Continental Shelf, produced by the North Sea Transition Authority and Lloyd's Register. The maps cover major geological time intervals and include products such as depth structure, isochore, and hydrocarbon occurrence maps. The project benefited from third-party data sources including Heriot-Watt University seismic interpretation and the 21CXRM Palaeozoic project.

Use Cases

• Model subsurface depth structures based on depth structure maps mentioned in the description
• Analyze sediment thickness and depositional patterns based on isochore and depositional facies maps
• Assess hydrocarbon prospectivity based on source rock and hydrocarbon occurrence maps
• Plan well placement and evaluate existing exploration based on well penetration maps

Strengths

• Maps are produced for major geological time intervals, including Paleocene, Lower Cretaceous, and Upper Jurassic
• Includes multiple derived products per interval, such as structural elements, reservoir distribution, and subcrop maps
• Integrates multiple third-party data sources, including seismic interpretation and a public domain Palaeozoic project

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
