Geochemical Oil And Source Rock Data From Northern Bonaparte Basin

Geochemical analysis delineates two distinct petroleum systems in the Northern Bonaparte Basin, offshore Northern Australia. The study correlates oils from Cretaceous and Jurassic reservoirs with specific source rock formations like the Echuca Shoals and Frigate formations. This data was published by Preston and Edwards in The APPEA Journal in 2000 and is hosted by the Australian Ocean Data Network.

Use Cases

• Classify oil chemical groups (e.g., marine vs. land-plant influenced) based on geochemical features to determine reservoir type and source affinity.
• Correlate hydrocarbon accumulations with specific source rock units like the Plover Formation or Flamingo Group using geochemical similarity metrics.
• Model short-range migration pathways by tracking variations in geochemical character between source-seal lithologies and accumulated liquids.
• Assess hydrocarbon prospectivity and risk by analyzing the geochemical range of Elang/Plover-reservoired oils and their inferred source inputs.

Strengths

• Data supports analysis of two distinct chemical groups of oils and condensates across multiple fields.
• Study correlates findings with specific geological formations and reservoir types across a defined geographic area.

Limitations

• Specific sample size, row count, and measurement columns are not provided.
• Data is from a study published in 2000, which may not reflect current reservoir conditions or exploration models.
• Geographic coverage is limited to the northeastern Ashmore and Cartier Islands and Zone of Co-operation Area A.
