West of Shetland and Rockall Regional Geological Maps for Hydrocarbon Exploration

A set of regional geological maps for the UK Continental Shelf's West of Shetland and West of Hebrides areas, produced by the North Sea Transition Authority and Lloyd's Register. The maps cover major geological intervals like the Paleocene and Upper Jurassic, and include products such as depth structure, isochore, and hydrocarbon occurrence maps. This public domain data integrates third-party sources including seismic interpretations from Aberdeen University and well data from CDA.

Use Cases

• Modeling subsurface depth structure based on depth structure maps
• Analyzing sediment thickness distribution based on isochore maps
• Mapping potential hydrocarbon reservoirs based on reservoir distribution maps
• Assessing source rock quality and distribution based on source rock maps
• Identifying structural trends and faults based on structural elements maps

Strengths

• Covers multiple geological time intervals including Paleocene, Lower Cretaceous, and Upper Jurassic
• Integrates multiple third-party data sources including seismic interpretation from Aberdeen University and CGG's Target database
• Includes a suite of at least eight distinct map products per time interval

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
