NSTA Central North Sea and Moray Firth Regional Geological Maps

NSTA published a set of regional geological maps for the Central North Sea and Moray Firth areas of the UKCS as part of its 2017/18 Activity Plan. The maps represent deliverables from a 3-year contract with Lloyd’s Register and cover main geological time intervals like Paleocene and Lower Cretaceous. Products include depth structure maps, isochore maps, facies maps, and associated digital data in formats like PDF, ArcGIS, .las, and .xyz.

Use Cases

• Analyze subsurface reservoir distribution based on reservoir distribution maps mentioned in the description.
• Model hydrocarbon migration pathways based on source rock maps and hydrocarbon occurrence maps.
• Study regional geological structure based on depth structure maps and structural elements maps.
• Assess sediment deposition patterns based on depositional facies maps and isochore maps.
• Plan exploration well placement based on well penetration maps and subcrop & supercrop maps.

Strengths

• Maps are produced for main geological time intervals, including Paleocene, Lower Cretaceous, and Upper Jurassic.
• The project benefited from multiple third-party data sources, including the 21st Century Roadmap Palaeozoic project and PGS's North Sea Digital Atlas.
• Output includes a series of layered PDF documents with explanations and stratigraphic charts.

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; last metadata update was 2026-06-18.
