Northern Bonaparte Basin Petroleum Geochemistry Analysis

Geochemical data delineates active petroleum systems in the Northern Bonaparte Basin offshore Australia. The study analyzes oils and source rock extracts from wells on the Laminaria and Flamingo highs, identifying distinct chemical groups correlating to reservoir types and source units.

Use Cases

• Correlate geochemical signatures of oils with source rock extracts from the Echuca Shoals, Plover, and Elang formations to delineate petroleum systems.
• Analyze the division of Elang/Plover-reservoired oils into land-plant-influenced and marine-influenced families based on geochemical data to understand source facies variation.
• Infer hydrocarbon migration pathway lengths by comparing geochemical character variations between source-seal lithologies and accumulated liquids.
• Assess hydrocarbon prospectivity and migration patterns by evaluating geochemical similarities between oils and Middle-to-Late Jurassic source rock extracts.

Strengths

• Data originates from a peer-reviewed study published in The APPEA Journal, providing authoritative analysis.
• Study specifically covers the northeastern Territory of Ashmore and Cartier Islands and western Zone of Co-operation Area A.
• Analysis distinguishes between oils from fracture porosity in the Early Cretaceous Darwin Formation and those from sandstones in the Jurassic Plover and Elang formations.

Limitations

• Dataset structure (rows, columns, sample data) is unknown, limiting immediate analytical utility.
• Primary data format is HTML, which may require extraction and transformation for computational analysis.
• Underlying raw geochemical measurements are not directly accessible in the provided description.
