The Browse Basin offshore Western Australia hosts major gas and condensate reserves, including the Ichthys and Brecknock accumulations. This dataset collates molecular, isotopic, and biomarker data to redefine four petroleum systems, updating prior research. It was published by the Australian Ocean Data Network and last updated in June 2026.
Use Cases
- Modeling gas and condensate origins based on molecular and isotopic datasets mentioned in the description
- Classifying petroleum systems based on 13C n-alkane isotopic profiles described
- Assessing biodegradation and recharge effects in oil and gas accumulations like Cornea and Gwydion
- Correlating source rocks with wet gases and oils, as noted for ongoing work
Strengths
- Includes specific resource estimates, such as 12.8 Tcf of gas and 527 million barrels of condensate for the Ichthys accumulation
- Defines four distinct petroleum systems with described source and reservoir characteristics
- Collates multiple data types including molecular, isotopic, and biomarker datasets
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Description metadata is limited; actual data quality requires manual inspection after download
