Geoscience Australia Data published a study analyzing hydrocarbon fluid samples from the Browse Basin, North West Shelf, Australia. The research used comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS) to examine diamondoids and semi-volatile aromatics in whole oil and condensate samples. Results demonstrate that numerous accumulations within the basin contain hydrocarbons from mixed sources, revealing a complex fill history.
Use Cases
- Correlating hydrocarbon fluids based on diamondoid and semi-volatile aromatic compound concentrations mentioned in the description.
- Identifying mixed-source petroleum accumulations using aromatic maturity ratios and stable carbon isotopic composition data.
- Investigating basin fill history by detecting high-maturity fluids in biodegraded accumulations like the greater Cornea field and Gwydion-1.
Strengths
- Analysis based on comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS).
- Data includes stable carbon isotopic composition for selected diamondoids and alkylbenzenes.
- Study identifies specific source rock formations, such as the Lower–Middle Jurassic Plover Formation and Upper Jurassic Vulcan Formation.
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 the Browse Basin, North West Shelf, Australia.
