A 1997 study presents isotopic and biomarker analyses of Cambrian to Permian oils and source rocks from the Arafura, Bonaparte, and Canning Basins. The data geochemically characterizes five distinct petroleum systems within the Larapintine and Gondwanan Supersystems. It was published by Edwards et al. in The APPEA Journal and is hosted by the Australian Ocean Data Network.
Use Cases
- Correlate hydrocarbon accumulations to specific source rock formations based on diagnostic isotopic signatures mentioned in the description.
- Characterize the maturity and richness of petroleum systems based on biomarker and kerogen analyses described.
- Distinguish between different Palaeozoic petroleum systems using the unique terpane and sterane signatures outlined.
- Re-evaluate the source of hydrocarbons in regions like the Timor Sea based on the identified Permian-like isotopic signatures.
Strengths
- Analysis covers a broad geological time range from the Cambrian to Permian periods.
- Identifies five distinct petroleum systems with specific geochemical markers, such as δ13C values and biomarker signatures.
- Correlates findings to specific geological formations like the Jigaimara, Goldwyer, and Gogo Formations.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data freshness should be verified; the underlying study is from 1997.
