Natural Gas Isotope Compositions from the Perth Basin, Australia

Geoscience Australia Data provides molecular and isotopic composition data for 34 natural gas samples from the onshore and offshore Perth Basin. The study extends previous work by Boreham et al. (2001) to include offshore samples and hydrogen isotope data. It demonstrates the existence of Jurassic to Permian gas systems in the basin.

Use Cases

• Identify gas source rock maturity based on carbon and hydrogen isotopic compositions.
• Distinguish between different gas systems (e.g., Jurassic vs. Permian) based on molecular composition.
• Correlate offshore and onshore gas accumulations using isotopic signatures.
• Assess the contribution of non-Kockatea Shale source rocks to the gas pool.

Strengths

• Includes data from 34 distinct natural gas samples.
• Extends previous research by incorporating offshore samples and hydrogen isotope data.
• Focuses on a specific, well-defined 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 is provided in PDF and PPTX formats, which may require extraction for analysis.
