Geochemical analyses of Cambrian to Permian oils and source rocks from the Arafura, Bonaparte, and Canning Basins characterize five distinct petroleum systems. The dataset likely contains isotopic signatures and biomarker data used to correlate oils with specific geological formations. The data was compiled by researchers and published in The APPEA Journal in 1997.
Use Cases
- Correlating hydrocarbon accumulations to specific source rock formations based on isotopic signatures.
- Identifying distinct petroleum systems using diagnostic biomarker signatures like steranes and gammacerane.
- Re-evaluating the source attribution of hydrocarbon accumulations based on geochemical fingerprints.
- Assessing the richness and maturity of potential source rocks for petroleum system modeling.
Strengths
- Characterizes five distinct petroleum systems (Larapintine 1-4 and Gondwanan 1) across multiple basins.
- Includes specific isotopic measurements (e.g., δ13Csat = -32 ‰ for Larapintine 1) and biomarker signatures.
- Correlates oils to specific geological formations (e.g., Jigaimara, Goldwyer, Gogo Formations) based on diagnostic features.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
