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

Geoscience Australia Data provides analytical results from hydrocarbon fluid correlation studies in the Browse Basin, North West Shelf, Australia. The data, associated with a 2020 Marine and Petroleum Geology publication, includes measurements of diamondoids and semi-volatile aromatic compounds from whole oil/condensate samples. Analyses demonstrate that numerous accumulations within the basin contain hydrocarbons from mixed sources, revealing a complex fill history.

Use Cases

• Correlating hydrocarbon fluids to specific source rocks based on diamondoid and semi-volatile aromatic compound signatures.
• Assessing fluid maturity levels using aromatic maturity ratios and stable carbon isotopic composition data.
• Identifying mixed-source hydrocarbon accumulations within a sedimentary basin.
• Reconstructing basin fill history by detecting the presence of high-maturity fluids in biodegraded accumulations.

Strengths

• Data is associated with a peer-reviewed publication in Marine and Petroleum Geology, Volume 113, 2020.
• Analyses were performed using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC-TOFMS).
• The study covers multiple named accumulations and fields, including Cornea, Gwydion-1, Mimia-1, and Concerto-1.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's last update is listed as 2026-04-20; freshness should be verified.
