Geoscience Australia's organic geochemistry database comprises analytical results for petroleum exploration samples, including source rocks, crude oils, and natural gases collected across Australia. The data are produced by techniques like programmed pyrolysis, gas chromatography, and mass spectrometry, sourced from industry reports, government sampling programs, and open publications. It enables mapping of total petroleum systems and supports resource decision-making.
Use Cases
- Correlating petroleum fluids to source rocks based on molecular and isotopic content.
- Mapping total petroleum system extent based on derived datasets and geological interpretations.
- Typing crude oils into families based on biomarker and bulk property analyses.
- Evaluating source rock compositional characteristics based on pyrolysis-gas chromatography data.
- Characterizing natural gas resources based on molecular and isotopic analyses.
Strengths
- Data originates from a wide range of analytical techniques, including pyrolysis, GC, GCMS, and GC-TC-IRMS.
- Sample data are sourced from industry reports under specific legislation, government geological programs, and open publications.
- The database enables digital discoverability and accessibility to key petroleum geochemical datasets via web services.
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 or source bias inherent to the collection from industry and government programs.
