Southwest Bairnsdale No. 1 Well: Geological and Drilling Summary for Gippsland Basin

Gippsland Basin, Victoria, Australia. This dataset is a summary report for the Southwest Bairnsdale No. 1 well, drilled to a total depth of 3926 feet between January 8 and February 14, 1963. The report details the stratigraphic objectives, results including sediment depths and a formation test, and the final classification as a dry hole. It was created by Geoscience Australia Data and sourced from data_gov_au.

Use Cases

• Analyze stratigraphic sequences and sediment depths based on the described Tertiary, Carboniferous, and Devonian layers.
• Study hydrocarbon exploration outcomes based on the reported formation test results and absence of shows.
• Research historical petroleum exploration subsidies based on the mention of the Petroleum Search Subsidy Act.
• Model subsurface geology based on the described pinch-out zones and granite basement depth.

Strengths

• Provides specific drilling dates (Jan 8 - Feb 14, 1963) and total depth (3926 feet).
• Contains detailed stratigraphic results, including depths for Tertiary (1408 ft) and Carboniferous-Devonian (3806 ft) sediments.
• Documents a concrete formation test result over the interval 2522 to 2559 feet.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to a single historical well report.
