Oil Development N.L. drilled the O.D.N.L. Penola No. 1 Well in South Australia between February and May 1961 to a depth of 4985 feet. The operation, conducted under a farm-out agreement, included electric and mud logging, testing, and coring to assess the petroleum potential of the Coonawarra subsurface structure. The well was abandoned as a dry hole after encountering only minor, non-commercial gas showings.
Use Cases
- Stratigraphic analysis based on the described sequence of Oligocene to Upper Jurassic marine and non-marine rocks.
- Assessing petroleum potential based on the documented geological formations and reported gas showings.
- Historical drilling analysis based on the detailed operational timeline, contractor, and rig specifications.
Strengths
- Detailed operational timeline spanning from 7th February to 5th May 1961.
- Specific geological depth markers for formations like the Gambier Limestone (215 feet) and Runnymede Formation (2380 feet thick).
- Clear provenance from a specific drilling operation by Oil Development N.L.
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 updated date is 2026-06-27 19:56:25.350396.
