NSTA and Lloyd's Register North Sea Regional Geological Maps

A set of regional geological maps for the North Sea area includes depth structure, isochores, subcrop and supercrop, structural elements, depositional facies, reservoir distribution, source rock, well penetration and hydrocarbon occurrence. The collection, provided by the North Sea Transition Authority and Lloyd's Register, also includes PDF documents with stratigraphic and petroleum systems charts and digital copies of sand flags (.las) and depth and thickness grids (.xyz).

Use Cases

• Model subsurface depth structure based on depth structure maps.
• Analyze petroleum systems based on source rock and hydrocarbon occurrence data.
• Assess reservoir distribution and depositional facies for exploration planning.
• Integrate well penetration data with regional stratigraphic charts.

Strengths

• Includes multiple map types covering depth structure, facies, and structural elements.
• Provides supplementary PDF documents with stratigraphic and petroleum systems charts.
• Offers digital data formats like .las and .xyz grids for direct analysis.

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 updated 2026-06-18 11:13:25.767258.
