Australian Hydrocarbon Geochemistry Data for Petroleum Systems Analysis

Geoscience Australia's database contains organic geochemical analyses of source rocks, crude oils, and natural gases collected across the continent. The collection integrates data from industry submissions under the OPGGSA 2006, government geological surveys, and open publications. It supports the mapping of total petroleum systems by correlating fluids to their source.

Use Cases

• Correlate crude oils to source rocks using biomarker and stable carbon isotope data to determine migration distances.
• Evaluate source rock maturity and generative potential using programmed pyrolysis results and vitrinite reflectance measurements.
• Characterize natural gas families by analyzing molecular composition and isotopic content from gas chromatography data.
• Map petroleum systems and depositional environments by integrating geochemical sample locations with geological interpretations.

Strengths

• Integrates data from multiple authoritative sources including industry, government surveys, and academic publications.
• Analytical results cover multiple sample types including source rocks, crude oils, and natural gases.

Limitations

• Specific row counts, column details, and sample sizes are not provided in the description.
• The temporal range of the sample collection is not explicitly stated.
