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. Data originates from industry reports under the OPGGSA 2006 and PSLA 1967, as well as from geological surveys by Geoscience Australia, state organizations, and open-file publications. It enables the typing of petroleum fluids into families and mapping of total petroleum systems.
Use Cases
Correlating crude oils to their source rock based on molecular biomarker and isotopic content.
Mapping petroleum system extent by determining depositional environment, age, and migration distances from fluid typing.
De-risking conventional and unconventional exploration programs using bulk compositional data from programmed pyrolysis.
Characterizing natural gas resources through molecular and isotopic analysis via gas chromatography.
Creating derived datasets on subsurface petroleum prospectivity, such as the 'Oils of Australia' series.
Strengths
Data is sourced from a wide range of authoritative entities, including Geoscience Australia, its predecessor organizations (AGSO, BMR), state geological surveys, and industry under specific Acts.
Analytical results are produced by multiple techniques, including programmed pyrolysis, GC-MS, and GC-TC-IRMS, providing diverse geochemical characterization.
The database supports the creation of value-add products and reports, such as the 'characterisation of natural gas' reports, documenting resource location and maturity.
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 2026-06-23 00:58:01.925215.
