Geochemical Characteristics of Early Carboniferous Petroleum Systems in Western Australia

A geochemical study establishes oil-oil correlations and evaluates potential source rocks within the latest Devonian–earliest Carboniferous succession of the onshore Canning Basin, Western Australia. The research compares the Ungani oilfield to the Larapintine 4 oil family and investigates unknown source rocks for Ungani and Wattle-1 ST1 oils. The dataset is associated with a 2020 publication in Marine and Petroleum Geology and is hosted by the Australian Ocean Data Network.

Use Cases

• Correlating oil families based on aromatic hydrocarbon and biomarker ratios mentioned in the description.
• Evaluating source rock potential for early Carboniferous petroleum systems based on geochemical signatures.
• Distinguishing oil origins using paleorenieratane concentrations and δ13C isotopic values described in the study.
• Modeling hydrocarbon generation potential (gas vs. liquid) from bulk geochemical properties of source rock samples.

Strengths

• Study is peer-reviewed and published in Marine and Petroleum Geology, Volume 113, 2020.
• Analysis includes multiple geochemical proxies: aromatic hydrocarbons, saturated biomarker ratios, and stable carbon isotopes.
• Geographic focus is specific to the Canning Basin, Western Australia, with comparisons across the Fitzroy Trough and Lennard Shelf.

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/temporal bias inherent to the specific study area and geological period.
