Geochemical Analysis of Gippsland Basin Hydrocarbon Sources and Reservoirs

16.5 TCF of gas, 4026 MMbbl of oil, 385 MMbbl of condensate, and 752 MMbbl of LPG were found in the Gippsland Basin as of 2012. The dataset provides a geochemical overview of these hydrocarbon accumulations, focusing on identifying multiple source rocks and migration pathways. This analysis is intended to support future exploration and assess risks for potential carbon dioxide sequestration.

Use Cases

• Correlating oils and condensates to specific source rock formations based on biomarker and stable isotope data.
• Assessing remaining hydrocarbon prospectivity in the eastern, less-explored part of the Gippsland Basin.
• Modeling petroleum systems to understand migration pathways between source and reservoir.
• Mitigating risk for potential carbon dioxide sequestration along the basin's southern and western flanks.

Strengths

• Contains specific, quantified resource estimates: 16.5 TCF gas, 4026 MMbbl oil as of 2012.
• Documents established oil-source rock correlations for specific wells and formations (e.g., Anemone-1A, Angler-1).
• Addresses a dual-purpose research need for both hydrocarbon exploration and carbon storage assessment.

Limitations

• Critical metadata is missing: no column names, row counts, file size, license, or author are provided.
• The dataset's structure is unclear; it is described as an 'overview' but the specific data format (beyond text) is not defined.
• The 'last updated' date is in the future (2026), indicating a potential metadata error or placeholder value.
