Australian Petroleum Source Rock and Fluids Atlas with Geochemical Data

Geoscience Australia's Organic Geochemistry Database (ORGCHEM) provides petroleum geochemical and geological data from onshore and offshore Australian basins. The services include visualizations for Pyrolysis, Organic Petrology, and molecular analyses like GCMS and CSIA. This data supports the characterization of petroleum source rocks and their derived fluids for systems analysis.

Use Cases

• Characterize petroleum source rock maturity based on Pyrolysis and Organic Petrology data
• Identify the origin of petroleum fluids using molecular and isotopic analyses like GCMS and CSIA
• Map the spatial distribution of source rocks and fluids from borehole and field site samples
• Assess petroleum composition for economic viability and required processing steps

Strengths

• Data is sourced from Geoscience Australia's authoritative Organic Geochemistry Database (ORGCHEM)
• Covers both onshore and offshore Australian basins, providing broad spatial coverage
• Includes multiple characterization methods: Pyrolysis, Organic Petrology, GCMS, and CSIA

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Australian basins
