A detailed geological log and drilling report for the O.D.N.L. Penola No. 1 Well in South Australia. The well was drilled to a total depth of 4985 feet between February and May 1961 by Oil Development N.L. The report describes the stratigraphic sequence penetrated, including Tertiary and Mesozoic rocks, and notes minor gas showings.
Use Cases
- Analyze stratigraphic sequences based on described rock formations and depths
- Study historical drilling operations based on contractor, rig type, and timeline details
- Evaluate petroleum potential based on descriptions of gas showings and structural testing
- Model subsurface geology based on seismic reflection traverse and interpreted discontinuities
Strengths
- Provides precise drilling timeline: commenced 7th February 1961, abandoned 5th May 1961
- Includes detailed stratigraphic depths, such as 215 feet of Gambier Limestone and 2380 feet of Runnymede Formation
- Specifies technical details: total depth of 4985 feet, rig type Failing 2500 - Holemaster
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 temporal bias inherent to a single historical drilling operation
