Geochemical Characteristics of Early Carboniferous Petroleum Systems in Western Australia

A geochemical study from the journal Marine and Petroleum Geology (2020) establishes oil-oil correlations and evaluates potential source rocks within the latest Devonian–earliest Carboniferous succession of the onshore Canning Basin, Western Australia. The data likely includes measurements of aromatic hydrocarbons, saturated biomarker ratios, and stable carbon isotopes to compare oil families like the Larapintine 4 and Ungani oils. The dataset is hosted by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Correlating oil samples based on aromatic hydrocarbon concentrations and stable carbon isotope values mentioned in the description.
• Evaluating source rock potential and maturity variations using hopane isomerisation ratios discussed in the study.
• Distinguishing between oil families like Larapintine 4 and Ungani based on paleorenieratane and isorenieratane levels described.
• Investigating unknown source rocks for oils with mixed molecular and isotopic features, as noted for the Wattle-1 ST1 sample.

Strengths

• Study is published in a peer-reviewed journal (Marine and Petroleum Geology, Volume 113, 2020).
• Analysis includes multiple geochemical proxies: aromatic hydrocarbons, saturated biomarker ratios, and stable carbon isotopes.
• Focuses on a specific geological timeframe (latest Devonian–earliest Carboniferous) and location (Canning Basin, Western Australia).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study area in Western Australia.
