Australian National Hydrocarbon Geochemistry Data Collection

Geoscience Australia's Australian National Hydrocarbon Geochemistry Data Collection comprises Oracle database tables from the Organic Geochemistry schema and derivative information in the Petroleum Systems Summary database. It captures analytical results for source rocks, crude oils, and natural gases from Australian sedimentary basins, supporting energy exploration and resource assessment.

Use Cases

• Analyze source rock organic geochemistry data to evaluate petroleum prospectivity by sedimentary basin.
• Model petroleum systems using compiled stable isotopic values from crude oils and natural gases.
• Conduct statistical evaluation of organic petrology data across basins for resource assessments.
• Support hydrogen exploration programs by integrating geochemistry data from sediment-hosted resources.

Strengths

• National-scale public database for Australian hydrocarbon geochemistry.
• Integrates data from industry submissions, government reports, and published research.
• Includes raw analytical values and derived interpretations in a Petroleum Systems Summary database.

Limitations

• Specific row counts, column details, and sample data are unavailable for review.
• Data is delivered in HTML format, which may require parsing for analytical use.
• Relies on compiled reports and external studies, potentially introducing heterogeneity in data quality.
