Gippsland Basin Petroleum Exploration Well Summary 1963

3926 feet of drilling data from the Southwest Bairnsdale No. 1 well, drilled in Victoria's Gippsland Basin between January and February 1963. The report details stratigraphic objectives, lithological sequences encountered, and results of formation testing, concluding with the well being plugged as a dry hole.

Use Cases

• Analyze stratigraphic sequences and lithological units like Tertiary sediments and Lower Carboniferous-Upper Devonian sandstones for basin modeling.
• Evaluate hydrocarbon potential using documented formation test results from the 2522 to 2559 feet interval and gas detector readings.
• Study drilling operations subsidized under the Petroleum Search Subsidy Act 1959-1961 as a case for historical exploration economics.

Strengths

• Report includes precise operational details: a total depth of 3926 feet and a specific drilling period from 8th January to 14th February 1963.
• Contains specific geological findings, including the depth of Tertiary sediments (1408 feet) and the composition of pre-Upper Devonian biotite granite.
• Documents a full programme of coring and logging, providing a basis for detailed subsurface analysis.

Limitations

• Data is confined to a single well report, limiting statistical analysis or regional generalization.
• No shows of hydrocarbons were found, and the formation test recovered only drilling mud, indicating negative results for resource discovery.
• Original data formats (HTML, PDF) are not machine-readable tabular data, requiring manual extraction for computational use.
