Betoota No. 1 Well Log: Drilling Data from Southwest Queensland

The Betoota No. 1 well was drilled to a total depth of 9,824 feet between December 1959 and April 1960. Delhi Australian Petroleum Ltd, Frome-Broken Hill Company Pty Ltd, and Santos Limited conducted a comprehensive program of electric and mud logging, testing, and coring. The operation established 5,757 feet of Mesozoic strata overlying 4,067 feet of probable Palaeozoic sediments.

Use Cases

• Analyze hydrocarbon potential based on detected hydrocarbon showings between 4,400 and 5,757 feet.
• Evaluate porosity zones based on water-bearing zones encountered from 3,450 to 5,757 feet.
• Study stratigraphic composition based on the presence of Mesozoic and Palaeozoic sediments.
• Identify potential source rocks based on marine and brackishwater shales found between specific depths.

Strengths

• Detailed operational timeline: drilling commenced on 22nd December 1959 and completed on 18th April 1960.
• Specific depth measurements: total depth of 9,824 feet with strata thicknesses precisely recorded.
• Comprehensive data collection program: electric and mud logging, testing, and coring were performed.

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 historical well.
