Browse Basin Petroleum Fluid Sources Analyzed with Semi-Volatile Compounds

Browse Basin, North West Shelf, Australia, hydrocarbon fluid samples analyzed using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS). The dataset includes diamondoid and semi-volatile aromatic compound data, aromatic maturity ratios, and stable carbon isotopic compositions to identify mixed hydrocarbon sources. The study, published in Marine and Petroleum Geology in 2020, reveals a complex fill history for accumulations including the greater Cornea field and Gwydion-1.

Use Cases

• Correlating hydrocarbon fluids to specific source rocks based on diamondoid and semi-volatile aromatic compound signatures.
• Assessing fluid maturity and mixing history in petroleum accumulations using aromatic maturity ratios.
• Modeling basin charge history by identifying contributions from different Jurassic formations like the Plover and Vulcan.
• Discriminating between biodegraded and high-maturity fluid components within reservoir samples.

Strengths

• Analysis based on compounds representing a significant proportion of the bulk fluid, unlike minor biomarker fractions.
• Data includes stable carbon isotopic composition for selected diamondoids and alkylbenzenes.
• Specific geographic focus on the Browse Basin, North West Shelf, Australia, with named field and well locations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Data may reflect geographic and temporal bias inherent to the specific study area and sampling period.
