Stable Isotope Compositions of Paleozoic Marine Crude Oils from the Canning Basin

17 Paleozoic marine crude oils from the Canning Basin, Western Australia, analyzed for stable carbon and hydrogen isotopic compositions of bulk, saturated, and aromatic hydrocarbons. The dataset includes isotopic profiles of individual C7+ n-alkanes for three major oil families. The isotopic data was used to refine the characterization of oil families and petroleum systems in the basin.

Use Cases

• Characterizing oil families based on bulk stable carbon isotopic composition trends.
• Investigating facies variations and thermal maturity levels in source rocks using biomarker-correlated isotope data.
• Comparing isotopic profiles of Paleozoic oils across different basins to refine petroleum system models.
• Typing oil families using multi-parameter analysis, as suggested by comparisons of Ordovician and Triassic-sourced oils.

Strengths

• Focuses on 17 specific Paleozoic marine crude oil samples from the Canning Basin.
• Includes both bulk and compound-specific (C7+ n-alkanes) stable carbon and hydrogen isotope data.
• Provides comparisons with oils from other Australian basins (Arafura, Bonaparte, Perth) and global marine oils.

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 on Western Australian basins.
