Geochemical Overview of Gippsland Basin Hydrocarbon Accumulations, 1965-2012

16.5 trillion cubic feet of gas and over 4 billion barrels of oil have been discovered in Australia's Gippsland Basin since 1965. This document from Geoscience Australia, presented at a 2015 conference, analyzes geochemical fingerprints to resolve uncertainties about petroleum sources and migration pathways. The data suggests sediments older than the Paleocene are significant petroleum sources within the basin.

Use Cases

• Modeling petroleum source rock contributions based on described geochemical fingerprinting correlations.
• Assessing exploration risk and prospectivity in the eastern Gippsland Basin based on the described resource distribution and uncertainties.
• Evaluating potential carbon dioxide sequestration sites along the basin flanks based on the described geological context.
• Correlating hydrocarbon fluids to specific source rock formations like the Golden Beach Subgroup based on the described biomarker parameters.

Strengths

• Provides specific resource totals: 16.5 TCF gas, 4026 MMbbl oil, 385 MMbbl condensate, 752 MMbbl LPG (Estimated Ultimate Recovery as of 2012).
• Includes concrete geochemical correlations, such as between the Anemone-1A oil and the Anemone Formation.
• Covers a significant time span of commercial activity, from the first discovery in 1965 to the 2012 assessment.

Limitations

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