Delhi-Santos Gidgealpa No. 1 Well Drilling Report from South Australia

A detailed report on the Delhi-Santos Gidgealpa No. 1 well drilled in South Australia in 1963. The well reached a total depth of 13,114 feet and was completed as a water well flowing from the Mooga Sandstone. It provided significant geological information, including the first subsurface encounter of Cambrian rocks in the Great Artesian Basin and encouraging hydrocarbon shows.

Use Cases

• Study Permian and Cambrian stratigraphy based on lithology and sequence thickness described in the report
• Analyze hydrocarbon show indicators in low-porosity sandstones mentioned in the description
• Research historical drilling operations subsidized under the Petroleum Search Subsidy Act
• Correlate geological formations between wells based on comparisons to Innamincka No. 1 and Dullingari No. 1

Strengths

• Report includes specific dates (spudded 28th August 1963, completed 6th December 1963) and precise depth measurements (13,114 feet total depth)
• Description provides detailed geological context, including lithology comparisons and the discovery of a 400-foot thick porous dolomite zone
• Data is sourced from a documented, historically significant exploration well subsidized under a government act

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 and temporal bias inherent to data_gov_au, focusing on a single 1963 well
