Australian Petroleum Source Rock and Fluids Atlas with Geochemical Analyses

Geoscience Australia's Petroleum Source Rock and Fluids Atlas provides up-to-date organic geochemical and geological data from the ORGCHEM database. The data includes spatial distributions of source rocks and derived fluids from onshore and offshore Australian basins, characterized by Pyrolysis, Organic Petrology, and molecular analyses. These data support petroleum systems analysis by characterizing source rocks and identifying derived petroleum fluids.

Use Cases

• Characterize petroleum source rock maturity based on Pyrolysis and Organic Petrology data.
• Identify correlations between source rocks and derived fluids using molecular and isotopic analysis data.
• Map the spatial distribution of petroleum source rocks and fluids across Australian basins for exploration.
• Assess petroleum composition for economic viability and processing requirements based on geochemical characterization.

Strengths

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

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 on Australian basins.
