Stable Isotope Compositions of 17 Paleozoic Marine Crude Oils from the Canning Basin

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, published by Geoscience Australia, compares these oils to other Australian and global marine oils to track systematic isotopic changes throughout the Paleozoic era. It includes n-alkane-specific isotopic profiles used to refine oil family characterization and petroleum system models.

Use Cases

• Characterizing oil families and petroleum systems based on stable carbon and hydrogen isotopic profiles.
• Tracking systematic changes in bulk stable carbon isotopic composition of marine oils throughout the Paleozoic era.
• Investigating the influence of source rock facies and thermal maturity on isotopic signatures.
• Comparing isotopic trends between different Australian basins, such as the Canning, Bonaparte, Arafura, and Perth Basins.

Strengths

• Focuses on 17 specific Paleozoic marine crude oil samples from a defined geographic region.
• Includes isotopic data for bulk, saturated, and aromatic hydrocarbon fractions, as well as individual C7+ n-alkanes.
• Provides comparative analysis 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 and temporal bias inherent to the specific basins studied.
