Australian Petroleum Source Rock and Fluids Atlas with Geochemical Data

Geoscience Australia's Organic Geochemistry Database provides petroleum geochemical and geological data from onshore and offshore Australian basins. The services visualize data on source rock pyrolysis, organic petrology, and molecular isotopic analyses to characterize petroleum systems. This dataset supports the analysis of petroleum composition and economic potential.

Use Cases

• Characterizing petroleum source rock maturity based on Pyrolysis and Organoclast Maturity data
• Identifying derived petroleum fluids (natural gas and crude oil) based on molecular and isotopic characterization
• Mapping the spatial distribution of source rocks and fluids based on borehole and field site samples
• Assessing petroleum system elements for economic commodity evaluation based on composition data

Strengths

• Data is sourced from Geoscience Australia's authoritative Organic Geochemistry Database
• Covers both onshore and offshore Australian basins, providing broad spatial coverage
• Includes multiple analytical data types such as Pyrolysis, GCMS, and Compound-Specific Isotopic Analyses

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 the sampled Australian basins
