Delhi-Santos Gidgealpa No. 1 Well: Geological Report for South Australia

Delhi-Santos Gidgealpa No. 1 Well is a geological report from a well drilled in 1963 in northeastern South Australia. The well reached a total depth of 13,114 feet, providing data on the Mesozoic and Permian sequences and the first subsurface encounter of Cambrian rocks in the Great Artesian Basin. The document, sourced from the Australian Ocean Data Network, details hydrocarbon shows and lithological findings from this subsidized exploration operation.

Use Cases

• Correlating subsurface stratigraphy based on described lithology of Permian and Cambrian sequences.
• Analyzing historical hydrocarbon show data from the Permian sequence mentioned in the report.
• Studying the geological structure of the Great Artesian Basin based on the well's location on a closed anticline.
• Researching the application of the Petroleum Search Subsidy Act for historical exploration projects.

Strengths

• Report contains specific factual details, including a total depth of 13,114 feet and drilling dates from August to December 1963.
• Provides unique geological information, being the first well to encounter Cambrian rocks in the subsurface of the Great Artesian Basin.
• Documents a 400-foot thick zone of porous dolomite in the Middle Cambrian and comparative analysis with nearby wells.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
