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 like programmed pyrolysis, gas chromatography, and mass spectrometry. Sample data originate from industry reports under the OPGGSA 2006 and PSLA 1967 acts, geological surveys, and open file publications.

Use Cases

• Correlating petroleum fluids to their source rock based on organic chemical analyses.
• Mapping total petroleum systems by determining depositional environment, age, and migration distances.
• Typing crude oils and natural gases into families using molecular and isotopic content data.
• Evaluating source rock potential using bulk compositional characteristics from pyrolysis and petrology.

Strengths

• Data originates from a national authority, Geoscience Australia, and its predecessor organizations.
• Includes connectivity to some inorganic analyses alongside organic chemical analyses.
• Samples are sourced from multiple streams including industry reports, geological surveys, and open publications.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-06-27 16:47:58.899854.
