Geochemical Analysis of Gippsland Basin Hydrocarbon Accumulations

Australian Ocean Data Network presents geochemical data on petroleum accumulations in the Gippsland Basin, detailing findings from over 50 years of exploration since 1965. The dataset includes analysis of source rock correlations, biomarker parameters, and molecular and carbon isotopic signatures for oil and gas fields. It was compiled for a presentation at the AAPG/SEG 2015 International Conference & Exhibition.

Use Cases

• Correlating oil and gas samples to specific source rock units like the Anemone Formation using biomarker parameters.
• Analyzing molecular and carbon isotopic signatures to distinguish terrestrial versus marine hydrocarbon sources.
• Mapping migration pathways between source and reservoir using geochemical fingerprinting data from fields like Barracouta and Longtom.
• Assessing the prospectivity of less-explored basin regions by comparing geochemical data from central and flank areas.

Strengths

• Covers 50 years of exploration history from the first discovery in 1965.
• Includes analysis of major resource totals: 16.5 TCF gas and over 4000 MMbbl oil.

Limitations

• Specific row counts and column names for geochemical measurements are not provided.
• Data is presented in summary form within HTML/PDF documents, not as a structured table.
