NSTA and Lloyd's Register Mid North Sea High and Forth Approaches Regional Geological Maps

The North Sea Transition Authority published a set of regional geological maps for the Mid North Sea High and Forth Approaches areas of the UK Continental Shelf. These maps represent the fifth set of deliverables from a 3-year contract with Lloyd's Register to produce maps and databases for the entire UKCS. The data is public domain and includes products like depth structure maps, isochore maps, and hydrocarbon occurrence maps for main geological time intervals.

Use Cases

• Model subsurface geological structures based on depth structure and structural elements maps.
• Analyze sediment distribution and reservoir potential based on depositional facies and reservoir distribution maps.
• Assess hydrocarbon prospectivity based on source rock and hydrocarbon occurrence maps.
• Plan well placement and evaluate subsurface penetration based on well penetration maps.
• Study stratigraphic relationships and geological history based on subcrop & supercrop maps.

Strengths

• Maps are produced for the entire UK Continental Shelf from a 3-year contract.
• Includes nine specific map product types such as depth structure and hydrocarbon occurrence maps.
• Project benefited from multiple third-party data sources including Heriot-Watt University seismic interpretation and the 21CXRM Palaeozoic project.
• Data is explicitly stated as public domain.

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 is listed as 2026-06-18.
