Petroleum Accumulations Report For The Carnarvon Basin

Seventy-three petroleum accumulations were documented in the Carnarvon Basin as of 30 June 1992. The report details their geological context, trapping mechanisms, and development infrastructure. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Classify accumulations by geological trap type (structural, stratigraphic) and reservoir rock age (Triassic, Cretaceous, Jurassic).
• Map the spatial distribution of fields across sub-basins like Barrow, Dampier, and Exmouth using location descriptions.
• Analyze the relationship between reservoir lithology (fluvio-deltaic sands, marine sandstones) and field size.
• Identify source and seal rock formations, such as Jurassic marine shales and Cretaceous claystones, for basin modeling.
• Track historical development status (in place, planned, decommissioned) and associated infrastructure (platforms, pipelines, processing plants).

Strengths

• Documents 73 specific petroleum accumulations with geological and developmental context.
• Provides detailed temporal context with a snapshot as of 30 June 1992, including 13 active and 9 planned developments.

Limitations

• Data is static and over 30 years old, not reflecting current field status or discoveries.
• Primary data format is PDF/HTML text, requiring manual extraction for quantitative analysis.
• No structured columnar data or sample records are provided for direct machine processing.
