13,114 feet was the total depth drilled for the Delhi-Santos Gidgealpa No. 1 Well in South Australia. The well was drilled by Delhi Australian Petroleum Ltd and Santos Limited between August and December 1963, subsidized under the Petroleum Search Subsidy Act. It provided significant geological information, including thick Mesozoic sequences and the first subsurface encounter of Cambrian rocks in the Great Artesian Basin.
Use Cases
- Analyze hydrocarbon shows in Permian sequences based on the description of numerous shows encountered
- Correlate lithology between wells based on the comparison to Dullingari No. 1 and Innamincka No. 1
- Evaluate porosity and permeability of sandstone reservoirs based on the mention of low porosity sandstones
- Study Cambrian marine carbonate formations based on the discovery of a thick dolomite zone
- Assess geological structure and stratigraphy based on the drilling location on an anticline flank
Strengths
- Total depth of 13,114 feet provides a significant vertical profile for analysis
- Detailed spudding and completion dates (28th August 1963 to 6th December 1963) offer precise temporal context
- Description includes specific comparisons to other wells (Innamincka No. 1, Dullingari No. 1) for regional correlation
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Freshness should be verified; last metadata update is 2026-04-16
