D.F.S. No. 1 Betoota: Geological Well Log Data from Queensland

A 9,824-foot deep exploratory well drilled in far southwest Queensland between December 1959 and April 1960 was found to be a dry hole. The operation, conducted by Delhi Australian Petroleum Ltd, Frome-Broken Hill Company Pty Ltd, and Santos Limited, included a comprehensive program of electric and mud logging, testing, and coring. Several hydrocarbon showings were detected between 4,400 and 5,757 feet but were deemed noncommercial, with porous zones found to be water-bearing.

Use Cases

• Analyzing Mesozoic and Palaeozoic stratigraphy based on the described 5,757 feet of Mesozoic strata overlying 4,067 feet of probable Palaeozoic sediments.
• Studying hydrocarbon source rock potential based on the described marine and brackishwater shales between 1,350-3,245 feet and 5,000-5,757 feet.
• Evaluating porosity and water saturation in subsurface reservoirs based on the described zones of good porosity found to be water-bearing from 3,450 to 5,757 feet.
• Historical analysis of drilling techniques and logging programs from the late 1950s and early 1960s as described in the operational details.

Strengths

• Detailed operational timeline spanning from December 22, 1959, to April 18, 1960.
• Specific depth measurements provided, including total depth of 9,824 feet and stratigraphic intervals.
• Explicit mention of multiple data collection methods: 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/temporal bias inherent to data_gov_au, being a single historical well.
