Description
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 techniques like programmed pyrolysis, gas chromatography-mass spectrometry, and isotopic analysis, sourced from industry submissions under the OPGGSA 2006, government geological programs, and open-file publications. It enables the typing of petroleum fluids into families and correlation to source rocks for mapping total petroleum systems.
Use Cases
Typing petroleum fluids into families based on molecular and isotopic biomarker content.
Correlating crude oils to their source rock to determine depositional environment and age.
Mapping the extent of total petroleum systems based on calculated values and geological interpretations.
Analyzing natural gas molecular and isotopic content for resource characterisation.
Strengths
Data sourced from a wide range of analytical techniques including GCMS and GC-TC-IRMS.
Samples originate from industry, government, and published sources under specific legislation like the OPGGSA 2006.
Includes connectivity to some inorganic analyses alongside organic chemical analyses.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
