Geochemical Overview of Gippsland Basin Hydrocarbon Accumulations, 1965-2012

A geochemical study of petroleum systems in Australia's Gippsland Basin, presented at the AAPG/SEG 2015 International Conference. The description details 16.5 TCF of gas, 4026 MMbbl of oil, 385 MMbbl of condensate, and 752 MMbbl of LPG discovered by the end of 2012. The data originates from the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Correlating oil and gas samples to specific source rock formations based on geochemical fingerprinting described in the study.
• Modeling petroleum migration pathways in the Gippsland Basin using the identified terrestrial and marine source affinities.
• Assessing remaining exploration prospectivity, particularly in the eastern basin, using the resource estimates and system uncertainties outlined.
• Evaluating risk for potential carbon dioxide sequestration projects along the basin's flanks based on the understanding of subsurface fluid systems.

Strengths

• Provides specific resource totals: 16.5 TCF gas, 4026 MMbbl oil, 385 MMbbl condensate, and 752 MMbbl LPG (Estimated Ultimate Recovery as of end-2012).
• Identifies specific geological formations, fields (e.g., Barracouta, Longtom), and wells (e.g., Volador-1, Anemone-1A) involved in the analysis.
• Contextualizes findings within a defined 50-year exploration and production timeline since the 1965 discovery.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is PDF/HTML, which may require extraction for quantitative analysis.
