The super-giant Ichthys gas accumulation is estimated to host 12.8 trillion cubic feet of gas and 527 million barrels of condensate. This dataset collates molecular, isotopic, and biomarker data for wet gases and crude oils from the Browse Basin offshore Western Australia, redefining four petroleum systems. It is hosted by the Australian Ocean Data Network and was last updated in May 2026.
Use Cases
- Model hydrocarbon migration and accumulation based on isotopic profiles and biomarker data.
- Identify source rock affinity for gas and condensate based on molecular and isotopic datasets.
- Assess biodegradation and recharge effects in oil and gas accumulations based on described compositional variations.
- Correlate wet gases and oils with their source rocks based on ongoing work mentioned in the description.
Strengths
- Includes detailed estimates for major accumulations, such as Ichthys (12.8 Tcf gas, 527 mmbbl condensate).
- Defines four distinct petroleum systems with specific source and reservoir characteristics.
- Collates multiple geochemical datasets including molecular, isotopic, and biomarker data.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction for quantitative analysis.
