Geochemical Oil And Source Rock Data For Northern Bonaparte Basin

Geochemical data delineates active petroleum systems in the offshore Northern Bonaparte Basin, specifically the northeastern Territory of Ashmore and Cartier Islands and western Zone of Co-operation Area A. The dataset analyzes oils and source rock extracts from wells on the Laminaria and Flamingo highs, identifying distinct chemical groups tied to reservoir formations. This study was published by Preston and Edwards in The APPEA Journal in 2000.

Use Cases

• Correlate oil families like 'Elang/Plover-reservoired oils' with source rock extracts from the 'Middle-to-Late Jurassic Plover and Elang formations' to map petroleum systems.
• Analyze geochemical variations between 'land-plant-influenced oils' from northwestern fields and 'marine-influenced oils' from southeastern fields to infer facies variation or secondary source inputs.
• Model short-range migration patterns by comparing geochemical character of hydrocarbon accumulations with source-seal lithologies like the 'Frigate Formation' or 'Flamingo Group'.
• Assess hydrocarbon prospectivity by evaluating the geochemical similarity between accumulated liquids and potential source units such as the 'Early Cretaceous Echuca Shoals Formation'.

Strengths

• Data supports delineation of multiple distinct petroleum systems and oil families within the basin.
• Analysis covers a specific geographic region with defined structural features like the Laminaria and Flamingo highs.

Limitations

• Sample size and row count for the underlying geochemical measurements are unknown.
• Data is derived from a study published in 2000, indicating potential temporal staleness for contemporary exploration.
• Specific column names, measurement types, and data formats are not provided, limiting direct analytical utility.
