Description
Drilled between August and December 1963, this dataset documents the Delhi-Santos Gidgealpa No. 1 exploratory well in South Australia. The well, drilled by Delhi Australian Petroleum Ltd and Santos Limited, reached a total depth of 13,114 feet and provided significant geological information on the Permian and Cambrian sequences in the Great Artesian Basin. The data originates from Geoscience Australia and was subsidized under the Petroleum Search Subsidy Act.
Use Cases
Correlating lithological sequences based on descriptions of Permian and Cambrian rock units.
Analyzing hydrocarbon shows and reservoir potential based on mentions of gas flows and porosity in sandstone and dolomite.
Studying the stratigraphy of the Mesozoic sequence and the regional angular unconformity described.
Researching historical petroleum exploration activities and subsidized drilling operations in Australia.
Strengths
Provides specific drilling dates (spudded 28th August 1963, completed 6th December 1963) and a precise total depth (13,114 feet).
Contains detailed geological observations, including the first subsurface encounter of Cambrian rocks in the Great Artesian Basin.
Documents operational details such as the rig used (National 80-B) and the drilling contractor.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is available only in PDF or HTML formats, which may complicate automated analysis.
