Lower Eocene Upper Ypresian T60 T82: UKCS Regional Aquifer Maps

The UK Continental Shelf is covered by a series of geological maps representing discrete stratigraphic intervals. These maps characterize the subsurface geological framework for potential aquifer-based storage, including CO₂ and hydrogen. They were produced by Lloyd’s Register and the OGA (now North Sea Transition Authority) by integrating seismic interpretation, well data, and regional geological understanding.

Use Cases

• Screen for intervals with favorable storage characteristics based on Gross Depositional Environment (GDE) and lithology.
• Assess regional aquifer presence and continuity for subsurface storage potential.
• Prioritize areas for detailed geological appraisal based on interpreted depositional facies and chronostratigraphic age.

Strengths

• Maps are built on integrated regional interpretations from seismic, well, and field data.
• Attribute information includes Gross Depositional Environment, Depositional Facies, Lithology Group, and Chronostratigraphic Age.
• Available in multiple geospatial formats including GEOJSON, GPKG, and ArcGIS REST API.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
