GeoStrat Jurassic Report (ArcGIS Version)

189 wells provide stratigraphic tops and interpretations for the Late Jurassic to Early Cretaceous Humber Group. The report, purchased by the OGA from Geostrat in 2017, includes a PDF, sequence maps, and well data in .csv and ArcGIS formats. The OGA has processed the data to integrate with its open data systems and provide Web Feature Services for automatic updates.

Use Cases

• Model subsurface sandstone play fairways based on the eight depositional sequence maps.
• Integrate stratigraphic tops and interpretations into proprietary GIS projects using the provided ArcGIS format.
• Analyze the sequence stratigraphy of the Humber Group across the UK Central Graben based on the 189 included wells.
• Correlate well data using the OGA-matched well names for consistency with other offshore datasets.

Strengths

• Includes data from 189 wells, providing a substantial basis for regional analysis.
• Delivers multiple output formats including a full PDF report, .csv files, and an ArcGIS project for flexibility.
• Well names have been matched to the OGA's official offshore wells dataset, aiding data integration.
• Web Feature Services (WFS) are included, ensuring block, licence, and quadrant data are automatically updated.

Limitations

• The report's contents do not necessarily reflect the technical view of the OGA, representing a third-party interpretation.
• Row count for the tabular well top data is unknown, which may limit suitability assessment.
• Column-level documentation for the .csv files is absent; field semantics must be inferred after download.
