Browse Basin Petroleum Fluid Geochemistry Using Diamondoids and Semi-Volatile Aromatics

Geoscience Australia provides geochemical data from hydrocarbon fluid correlation studies in the Browse Basin, North West Shelf, Australia. The dataset includes analyses of diamondoids and semi-volatile aromatic compounds from whole oil and condensate samples, used to identify multiple petroleum sources. The data supports research published in Marine and Petroleum Geology, Volume 113, 2020.

Use Cases

• Correlating hydrocarbon fluids to specific source rocks based on diamondoid and semi-volatile aromatic compound signatures.
• Assessing the maturity of petroleum fluids using aromatic maturity ratios and stable carbon isotopic composition data.
• Identifying mixed-source hydrocarbon accumulations within a sedimentary basin.
• Refining fluid discrimination models that are primarily based on saturated biomarker compositions.

Strengths

• Data is derived from comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC-TOFMS).
• Analysis includes multiple compound classes: diamondoids, semi-volatile aromatics, alkylbenzenes, and stable carbon isotopes.
• Samples are from specific, named fields and wells (e.g., Cornea, Gwydion-1, Kronos-1) in the Browse Basin.

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.
