Australian Petroleum Accumulations in the Carnarvon Basin, 1992 Report

Seventy-three petroleum accumulations were documented in the Carnarvon Basin as of June 1992. The report from Geoscience Australia details their geological context, including trapping mechanisms and reservoir rocks from Triassic to Cretaceous sequences. It also lists the development infrastructure, both offshore and onshore, that was in place or planned at the time.

Use Cases

• Mapping hydrocarbon prospectivity based on described structural and stratigraphic traps.
• Analyzing the historical development of oil and gas fields based on the listed infrastructure and production status.
• Studying the relationship between plate tectonics (rifting) and petroleum systems as described for the Mesozoic sequence.
• Correlating specific reservoir rock types (e.g., Triassic fluvio-deltaic sands) with known accumulations like Wanaea and Cossack.

Strengths

• Provides a specific count of 73 petroleum accumulations identified by a cutoff date.
• Offers detailed geological context, including specific sub-basins, rock ages, and trapping mechanisms.
• Lists concrete development infrastructure, naming 13 active and 9 planned developments along with specific facilities and islands.

Limitations

• Data is historical, with a snapshot from June 1992; freshness should be verified.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The primary file formats are PDF and HTML, which may require extraction for structured analysis.
