Perth Basin Natural Gas Isotope Compositions

Australian Ocean Data Network provides molecular and isotopic composition data for 34 natural gas samples from the onshore and offshore Perth Basin. The study extends prior work by including hydrogen isotope data and offshore samples, identifying Jurassic to Permian gas systems. The dataset was last updated in April 2026.

Use Cases

• Correlate gas samples to source rock age (Jurassic, Permian) using carbon and hydrogen isotope compositions.
• Analyze the molecular composition of gases to distinguish between different petroleum systems in the Perth Basin.
• Compare onshore versus offshore gas geochemistry using the sample location data to assess basin-scale variability.

Strengths

• Contains data for 34 distinct natural gas samples.
• Extends previous studies by including hydrogen isotope data and offshore samples.

Limitations

• Small sample size of 34 gases limits statistical power for broad conclusions.
• Primary data is presented in report formats (PPTX, PDF), not a structured data table.
