Australian Organic Geochemistry Database for Petroleum Exploration

Geoscience Australia's 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 reports under the OPGGSA 2006 and PSLA 1967, as well as from geological sampling programs by Geoscience Australia and state organizations.

Use Cases

• Typing petroleum fluids into families based on molecular and isotopic content.
• Correlating crude oils to their source rock to determine depositional environment and age.
• Mapping the extent of total petroleum systems based on geochemical correlations.
• Assessing source rock maturity and hydrocarbon potential using bulk compositional data from pyrolysis.

Strengths

• Data originates from a national authority, Geoscience Australia, and its predecessor organizations.
• Includes multiple sample types (source rocks, crude oils, natural gases) and analytical techniques.
• Sourced from a mix of industry submissions under specific acts and government geological programs.

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.
