Geoscience Australia's organic geochemistry database comprises analytical results for petroleum exploration samples, including source rocks, crude oils, and natural gases collected across the Australian continent. The data are produced by a wide range of analytical techniques, such as programmed pyrolysis, gas chromatography, and mass spectrometry. Sample data originate from industry submissions under the OPGGSA 2006 and PSLA 1967 acts, as well as from geological surveys and open-file publications.
Use Cases
- Correlating petroleum fluids to their source rock based on molecular and isotopic content.
- Mapping total petroleum systems by determining depositional environment, age, and migration distances.
- Typing crude oils and natural gases into families for basin analysis using biomarker and isotopic data.
- De-risking conventional and unconventional petroleum exploration programs with open-file analytical results.
Strengths
- Data originates from a national authority, Geoscience Australia, and its predecessor organizations.
- Includes samples collected under specific legislative acts (OPGGSA 2006 and PSLA 1967).
- Analytical results are produced by multiple techniques, such as GC-MS and GC-TC-IRMS.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
