Australian Petroleum Source Rock and Fluids Geochemical Atlas

Geoscience Australia's Organic Geochemistry Database provides petroleum source rock and fluid data from onshore and offshore Australian basins. It includes Pyrolysis, Organic Petrology, and molecular analyses like Compound-Specific Isotopic Analyses and Gas Chromatography-Mass Spectrometry for petroleum systems characterization. The data is published by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Characterize source rock maturity and generative potential using Pyrolysis data and Maceral Reflectance values.
• Correlate oils and gases to their source rocks using molecular data from Whole Oil GC and Compound-Specific Isotopic Analyses (CSIA).
• Map the spatial distribution of petroleum source rocks and derived fluids across Australian basins from borehole and field site samples.
• Assess petroleum composition for economic viability and required processing steps using Bulk and GCMS data tables.

Strengths

• Data covers both onshore and offshore Australian basins, providing broad spatial coverage.
• Includes multiple analytical techniques like Pyrolysis, Organic Petrology, GCMS, and CSIA for comprehensive characterization.
• Managed by Geoscience Australia, an authoritative national geoscience organization.

Limitations

• Specific row counts, column details, and sample sizes are not provided.
• Data formats (WFS, HTML, WMS) are primarily for visualization and service access, not direct analytical file formats.
• License terms for data use and redistribution are unknown.
