Stable carbon and hydrogen isotopic compositions of Paleozoic marine crude oils from the C

17 Paleozoic marine crude oil samples from the Canning Basin, Western Australia, analyzed for stable carbon and hydrogen isotopic compositions of bulk, saturated, and aromatic hydrocarbons. The dataset, sourced from the Australian Ocean Data Network, compares these oils to others from west Australia and globally to identify systematic isotopic changes throughout the Paleozoic era. The isotopic data has been used to refine the characterization of oil families and petroleum systems.

Use Cases

• Correlating oil families based on bulk stable carbon isotopic composition trends mentioned in the description.
• Investigating source rock facies variations and thermal maturity levels using n-alkane-specific carbon and hydrogen isotopic profiles.
• Comparing Paleozoic marine oil isotopic signatures across different Australian basins, such as the Canning, Bonaparte, Arafura, and Perth Basins.
• Refining petroleum system models for the Canning Basin using integrated biomarker and isotopic data.

Strengths

• Focuses on 17 specific Paleozoic marine crude oil samples from the Canning Basin.
• Includes isotopic data for bulk hydrocarbons, saturated fractions, and aromatic fractions.
• Provides n-alkane-specific carbon and hydrogen isotopic profiles for three major oil families.
• Enables comparison with other Australian and global marine oils and source rocks.

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 west Australian basins.
