Browse Basin Petroleum Fluid Compositions Analyzed via GC×GC-TOFMS

Hydrocarbon fluid data from the Browse Basin, Australia, analyzed using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS). The study, published in Marine and Petroleum Geology in 2020, identifies multiple petroleum sources in basin accumulations using semi-volatile aromatics and diamondoids. Data likely includes compound concentrations, maturity ratios, and stable carbon isotopic compositions for samples from fields like Cornea, Gwydion-1, Mimia-1, and Kronos-1.

Use Cases

• Correlating hydrocarbon fluids based on semi-volatile aromatic and diamondoid compound profiles mentioned in the description.
• Assessing fluid maturity using aromatic maturity ratios and stable carbon isotopic composition data described.
• Identifying mixed-source accumulations within a sedimentary basin, as demonstrated for the Browse Basin.
• Refining fluid discrimination models that are primarily based on saturated biomarker compositions.

Strengths

• Analytical method is specified: comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS).
• Specific geographic focus on the Browse Basin, North West Shelf, Australia, with named sample locations (e.g., Cornea field, Gwydion-1).
• Study is peer-reviewed and published in Marine and Petroleum Geology, Volume 113, 2020.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on the Browse Basin.
