APT Geochemical Database: Oil Provenance and Quality West of Shetlands

APT's West of Shetlands geochemical database was purchased 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 released for use by potential 30th Licensing Round applicants.

Use Cases

• Evaluate oil source rock characteristics based on geochemical data.
• Assess oil quality and maturity for exploration targeting based on geochemical parameters.
• Correlate geochemical data with associated images for geological interpretation.

Strengths

• Data was purchased with publication rights by a national authority (North Sea Transition Authority) in March 2017.
• Includes explanatory 'dataKEYS' tabs within the spreadsheets to describe content.
• Contains an index linking to associated images for context.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data is delivered in the format it was received, which may require preprocessing.
