APT Geochemical Database: Oil Provenance and Quality in West of Shetlands

A geochemical database for the West of Shetlands region, purchased with publication rights by the North Sea Transition Authority in March 2017. The data is delivered in its original format, including spreadsheets with explanatory tabs and an index to associated images. It was made public for potential applicants to the 30th Licensing Round.

Use Cases

• Evaluate oil source rock characteristics based on geochemical parameters.
• Assess reservoir quality and fluid properties for exploration targets.
• Correlate geochemical data with geological interpretations using associated images.

Strengths

• Includes explanatory 'dataKEYS' tabs within spreadsheets to clarify content.
• Contains an index to associated images within the primary data spreadsheet.
• Data was purchased with publication rights by a national authority (NSTA).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
