Australian Petroleum Accumulations in the Gippsland Basin, Victoria

125 onshore and over 80 offshore exploration wells have been drilled in the Gippsland Basin, resulting in the discovery of 11 economic, 26 subeconomic, and 6 uneconomic petroleum accumulations. The report, likely from Geoscience Australia, details cumulative production figures and estimated remaining reserves as of 31 December 1986. Petroleum is found in structural traps within Oligocene to Late Cretaceous sequences and is of land-plant origin.

Use Cases

• Analyze historical exploration success rates based on the reported counts of economic, subeconomic, and uneconomic accumulations.
• Model petroleum reserves and production trends based on the reported cumulative and estimated remaining volumes of oil, condensate, LPG, and sales gas.
• Study the geological characteristics of petroleum deposits based on the described structural traps and Oligocene to Late Cretaceous sequences.
• Compare the properties of crude oils and condensates based on the reported API gravity ranges from 14.6 to 63 degrees.

Strengths

• Provides specific historical production and reserve figures, such as 344.66 x 10^6 m³ of cumulative oil production.
• Includes detailed geological context, specifying the origin of petroleum and the age of the reservoir sequences.
• Reports precise counts of exploration outcomes, including 11 economic and 26 subeconomic offshore accumulations.

Limitations

• Data is historical, with key figures current only as of the end of 1986.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
