Combined GCxGC-TOFMS and compound-specific isotope analysis data for diamondoids, n-alkanes, and aromatic hydrocarbons from the Browse Basin, Australia. The dataset, hosted by the Australian Ocean Data Network, aims to unravel complex hydrocarbon charge histories by analyzing source-specific and biodegradation-resistant compounds. It includes analyses of non-biodegraded (Caswell) and biodegraded (Cornea, Gwydion) oil fields.
Use Cases
- Identifying mixed hydrocarbon contributions to oil accumulations based on diamondoid concentrations and ratios.
- Assessing thermal maturity and source rock type based on biomarker parameters and diamondoid yields.
- Investigating the effects of biodegradation on hydrocarbon signatures using compound-specific isotope analysis of diamondoids.
- Correlating gas escape events with residual fluid composition using high diamondoid concentration data.
Strengths
- Data generated using comprehensive two-dimensional gas chromatography (GCxGC-TOFMS), which minimizes interference from co-eluting compounds.
- Analyses focus on diamondoids, compounds described as source-specific and highly resistant to thermal maturity and biodegradation.
- Includes compound-specific isotope analysis (CSIA) data for n-alkanes, aromatic hydrocarbons, and diamondoids.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Primary data format is PDF, which may require extraction for computational analysis.
