Carnarvon Basin Petroleum Accumulations and Infrastructure Report

Seventy-three petroleum accumulations were documented in the Carnarvon Basin as of June 1992, with most located offshore in Triassic to Cretaceous rocks. The report details trapping mechanisms, reservoir geology, and production infrastructure, compiled by the Australian Ocean Data Network. This historical snapshot provides a foundation for understanding the basin's development prior to 1992.

Use Cases

• Analyze the distribution of 73 accumulations across sub-basins like Barrow, Dampier, and Exmouth to model regional petroleum systems.
• Correlate trapping mechanisms (structural, stratigraphic) with specific reservoir levels in the Mesozoic sequence for exploration targeting.
• Map development infrastructure (platforms, pipelines, processing plants) against accumulation locations to assess historical production logistics.

Strengths

• Documents 73 specific petroleum accumulations with geological context.
• Provides detailed descriptions of reservoir rocks, source seals, and trapping mechanisms.
• Lists 13 active and 9 planned developments with associated infrastructure as of 1992.

Limitations

• Data is temporally stale, with a cutoff date of June 1992 and no updates on subsequent discoveries.
• Lacks quantitative, machine-readable data (e.g., coordinates, reserve volumes) as information is embedded in report text.
• Sample size is fixed at the 73 accumulations known at the report date, excluding later finds.
