Petroleum Geochemistry of Oils and Source Rocks from the Northern Bonaparte Basin

Geochemical data delineates active petroleum systems in the Northern Bonaparte Basin offshore Northern Australia. The study analyzes oils and source rock extracts from wells on the Laminaria and Flamingo highs, dividing them into distinct chemical groups based on reservoir and source affinity. The dataset is associated with a 2000 journal publication by Preston and Edwards.

Use Cases

• Correlating hydrocarbon accumulations with source rock units based on geochemical signatures described in the study
• Modeling short-range hydrocarbon migration patterns based on the described structural complexity and geochemical variations
• Classifying oils into families (e.g., land-plant-influenced vs. marine-influenced) for regional prospect evaluation
• Assessing the influence of local source-seal lithologies (e.g., Frigate Formation, Flamingo Group) on oil chemistry

Strengths

• Data is tied to a peer-reviewed journal publication (The APPEA Journal, 2000)
• Description provides specific geological context, including formation names (Darwin, Plover, Elang) and field examples (Laminaria, Bayu-Undan)
• Analysis distinguishes between multiple oil families and their proposed source units

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data freshness should be verified; metadata indicates a last update of 2026-04-10
