Western Australia's Canning Basin is the focus of a geochemical study correlating oil families and evaluating source rocks from the latest Devonian to earliest Carboniferous period. The research compares the Ungani oilfield with the Larapintine 4 oil family using aromatic hydrocarbons, saturated biomarker ratios, and stable carbon isotopes. It was published by Geoscience Australia in the journal Marine and Petroleum Geology in 2020.
Use Cases
- Correlating oil samples based on aromatic hydrocarbon concentrations and biomarker ratios described in the study.
- Evaluating potential source rock maturity and composition using hopane isomerisation ratios mentioned in the description.
- Distinguishing between oil families using stable carbon isotope values for n-alkanes, pristane, and phytane as outlined.
- Investigating unknown source rock origins for oils with unusual molecular and isotopic features similar to the Wattle-1 ST1 sample.
Strengths
- Study is peer-reviewed and published in Marine and Petroleum Geology, Volume 113, 2020.
- Analysis uses multiple geochemical techniques including aromatic hydrocarbons, biomarker ratios, and stable carbon isotopes.
- Focuses on a specific geological period (latest Devonian–earliest Carboniferous) and region (onshore 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 data_gov_au, focusing solely on the Canning Basin.
