Delhi-Santos Gidgealpa No. 1 Well Log and Geological Report

Gidgealpa No. 1 was drilled to a total depth of 13,114 feet in 1963 in South Australia. The well provided significant geological information, including the first subsurface encounter of Cambrian rocks in the Great Artesian Basin and more hydrocarbon shows in the Permian sequence than any other well in the region at the time. The data was collected by Delhi Australian Petroleum Ltd and Santos Limited and is hosted by the Australian Ocean Data Network.

Use Cases

• Analyze Permian and Cambrian stratigraphy based on lithology descriptions
• Study hydrocarbon shows and reservoir characteristics based on porosity and flow test results
• Model subsurface geology of the Great Artesian Basin based on structural and sequence data
• Research historical petroleum exploration methods based on drilling and subsidy details

Strengths

• Contains detailed spudding, depth, and completion dates (28th August 1963 to 6th December 1963)
• Documents a specific, historically significant well depth of 13,114 feet
• Provides concrete geological findings like a 400-foot-thick Middle Cambrian dolomite zone

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
