D.F.S. No. 1 Betoota: Geological Well Log from 1959-1960 Drilling

The Betoota No. 1 well dataset documents a drilling operation in far southwest Queensland conducted by Delhi Australian Petroleum Ltd, Frome-Broken Hill Company Pty Ltd, and Santos Limited. Drilling commenced on 22 December 1959 and was completed on 18 April 1960, reaching a total depth of 9,824 feet. The dataset includes results from a comprehensive program of electric and mud logging, testing, and coring to assess hydrocarbon potential and stratigraphy.

Use Cases

• Analyze stratigraphic composition based on the described 5,757 feet of Mesozoic and 4,067 feet of probable Palaeozoic sediments.
• Evaluate hydrocarbon source rock potential based on described shale intervals between 1,350-3,245 feet and 5,000-5,757 feet.
• Study porosity and water saturation in zones between 3,450 feet and 5,757 feet where good porosity was encountered.
• Investigate non-commercial hydrocarbon showings detected between 4,400 feet and 5,757 feet.

Strengths

• Detailed operational timeline: drilling from 22 Dec 1959 to 18 Apr 1960.
• Specific depth measurements: total depth of 9,824 feet with stratigraphic breakdowns.
• Comprehensive data collection program described, including electric logging, mud logging, testing, and coring.

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 and temporal bias inherent to a single 1959-1960 well.
