Geochemical datasets including molecular and isotopic data for wet gases, hydrocarbon liquids, biomarkers, and isotopic ratios for crude oils from the Browse Basin offshore Western Australia. The data was collated by the Australian Ocean Data Network to redefine four petroleum systems, with work ongoing to correlate fluids with source rocks.
Use Cases
- Modeling complex gas accumulation filling based on multiple organic and inorganic source data
- Analyzing biodegradation and recharge extents in oil and gas accumulations based on biomarker profiles
- Redefining petroleum system boundaries based on isotopic profiles of n-alkanes
- Correlating wet gases and oils with their source rocks based on molecular and isotopic datasets
Strengths
- Includes data for super-giant accumulations like Ichthys (12.8 Tcf gas, 527 mmbbl condensate) and Brecknock/Calliance/Torosa (15.9 Tcf gas, 436 mmbbl condensate)
- Collates multiple geochemical datasets: molecular, isotopic, biomarker, and n-alkane isotopic ratios
- Defines four distinct petroleum systems with specific source and reservoir characteristics
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
