Australian Hydrocarbon Geochemistry and Petroleum Systems Database

Geoscience Australia's national collection includes raw organic geochemistry, petrology, and stable isotope data for source rocks, crude oils, and natural gases, compiled from industry submissions, research projects, and published reports. The data supports analysis of petroleum systems across onshore and offshore Australian sedimentary basins. It is maintained by Geoscience Australia and was updated in April 2026.

Use Cases

• Evaluate source rock potential by analyzing organic geochemistry data like TOC and Rock-Eval parameters across different basins.
• Correlate crude oils and natural gases to their source rocks using stable isotope values and biomarker data.
• Model petroleum systems by integrating raw analytical results on source rocks, oils, and gases into basin-scale statistical evaluations.
• Assess hydrogen exploration prospects by studying geochemical data relevant to sediment-hosted energy resources.

Strengths

• National-scale coverage of Australian sedimentary basins, both onshore and offshore.
• Compiles data from multiple authoritative sources including industry reports, government studies, and academic theses.
• Includes derivative interpreted data in the Petroleum Systems Summary database for statistical basin evaluation.

Limitations

• Specific row counts, column details, and sample sizes are not provided.
• Data is derived from multiple sources with varying original collection methods, potentially introducing heterogeneity.
• Temporal coverage for the individual analytical records is not specified.
