Mount Salt No. 1 Well Drilling And Stratigraphy Report Otway Basin

Geoscience Australia provides a report on the Mount Salt No. 1 well, drilled to 10,044 feet in 1962 to test Cretaceous petroleum potential. The document details a full logging, testing, and coring program, noting traces of crude oil and a gas show. It covers the stratigraphic sequence from Oligocene to Cretaceous sediments in the Otway Basin, South Australia.

Use Cases

• Analyze the stratigraphic column described, from Oligocene/Eocene-Palaeocene sediments to Upper Cretaceous sands and siltstones, for geological correlation studies.
• Investigate petroleum potential indicators like the crude oil traces from core analysis and gas show from the 9830-9848 feet interval.
• Review drilling and testing details, including the five attempted drillstem tests and the single successful test that recovered 4070 feet of saline water.
• Study the subsidized drilling operation under the Petroleum Search Subsidy Act from 980 feet to total depth for historical energy policy context.

Strengths

• Report includes specific technical measurements like the total well depth of 10,044 feet and a detailed 3260-foot sediment sequence.
• Contains precise operational dates, with drilling from 9th May to 21st September 1962.
• Documents concrete findings from exploration, such as traces of crude oil and a recorded gas show.

Limitations

• Data is presented as a static historical report in HTML/PDF format, not as structured, queryable tabular data.
• Information is temporally stale, reflecting a single drilling operation completed over 60 years ago.
• The report's stratigraphic correlations contain uncertainties, as noted with the base of the Upper Cretaceous not being clearly defined.
