Organic Geochemistry Analysis of the Petrel Sub-basin Petroleum System

AGSO's 1995-1996 study provides geochemical data on oils and source rocks from Australia's Petrel Sub-basin. The research aimed to define the basin's structural development and factors controlling its petroleum systems. It was conducted by the Marine, Petroleum and Sedimentary Resources Division as part of the North West Shelf Project.

Use Cases

• Correlating oil samples to potential source rock units based on organic geochemistry parameters.
• Modeling thermal maturity and hydrocarbon generation potential of source rock intervals.
• Analyzing the influence of basement elements and tectonic events on basin fill and petroleum system development.
• Mapping the spatial distribution of geochemical properties to identify exploration sweet spots.

Strengths

• Study conducted by a national geological survey (AGSO) with authoritative expertise.
• Focuses on a defined geographic region (Petrel Sub-basin) and time period (1995-1996).
• Integrates multiple geological disciplines including stratigraphy, structure, and geochemistry.

Limitations

• Primary data format is PDF reports, requiring manual extraction for quantitative analysis.
• Data is over 25 years old and may not reflect current exploration knowledge.
• Specific sample counts, analytical measurements, and row/column details are unavailable.
