Natural Gas Isotope Compositions from the Onshore and Offshore Perth Basin, Australia

The Perth Basin in Australia is the focus of this dataset, which presents molecular and isotopic compositions for 34 natural gas samples. The data extends a previous study to include offshore samples and hydrogen isotope measurements. It was published by the Australian Ocean Data Network and last updated on 2026-06-17.

Use Cases

• Identify gas source rock origins based on carbon and hydrogen isotope systematics.
• Distinguish between Jurassic and Permian gas systems in the Perth Basin.
• Correlate offshore and onshore gas samples to understand regional petroleum systems.
• Validate geological models of the Early Triassic Kockatea Shale as a principal source rock.

Strengths

• Includes 34 distinct natural gas samples.
• Extends previous work by adding offshore samples and hydrogen isotope data.
• Focuses on a specific, well-studied geological region (Perth Basin).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in presentation/document formats (PPTX, PDF), which may complicate direct analysis.
