Gippsland Basin Petroleum Accumulations Report with 1986 Production and Reserve Estimates

88 percent of Australia's cumulative crude oil production to 1986 came from the Gippsland Basin in Victoria. This report from Geoscience Australia details the discovery of 11 economic, 26 subeconomic, and 6 uneconomic offshore petroleum accumulations, along with cumulative production and remaining recoverable reserve figures as of December 31, 1986. The petroleum is found in structural traps within Oligocene to Late Cretaceous sequences and is believed to be of land-plant origin.

Use Cases

• Analyzing historical production trends based on cumulative oil, condensate, LPG, and sales gas volumes.
• Studying the economic viability of petroleum discoveries based on the reported counts of economic, subeconomic, and uneconomic accumulations.
• Modeling geological formations based on described trap types (structural/stratigraphic) and host sequences (Oligocene, Eocene, Paleocene, Late Cretaceous).
• Researching hydrocarbon characteristics based on reported API gravity ranges for crude oils and condensates.

Strengths

• Provides specific, quantified historical production and reserve data (e.g., 344.66 x 10^6 m³ of oil, 206.39 x 10^9 m³ of sales gas).
• Offers detailed geological context, including trap types, host rock sequences, and theories on petroleum origin.
• Includes a clear breakdown of discovery outcomes, specifying counts of economic, subeconomic, and uneconomic accumulations.

Limitations

• Data is historical, with key figures current only as of December 31, 1986; freshness should be verified.
• Column-level documentation is absent; field semantics and data structure must be inferred after download from the PDF/HTML files.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
