Geltwood Beach No. 1 Well Drilling And Stratigraphic Log

A 1963 drilling report for the Geltwood Beach No. 1 well in the Otway Basin of South Australia. The document details the well's stratigraphy, drilling operations, and hydrocarbon testing results. It was created by the Australian Ocean Data Network and subsidized under the Petroleum Search Subsidy Act.

Use Cases

• Analyze stratigraphic sequences from surface to 12,300 feet depth for regional geological modeling.
• Study gas trace occurrences recorded between 4500 feet and total depth for seepage indicators.
• Review results of five drillstem tests that yielded gas-cut salty water and mud.
• Examine the interpreted wedge-out of Middle to Upper Cretaceous sediments based on nearby well evidence.
• Assess the economic outcome of a subsidized exploration well drilled to test a closed structure.

Strengths

• Report contains specific depth measurements for geological formations, such as 45 feet of Recent calcareous sand.
• Provides exact drilling dates from August 22 to November 10, 1963, and a total depth of 12,300 feet.

Limitations

• Dataset is a single historical document with no structured tabular data or row count.
• Information is temporally stale, describing a single drilling operation completed in 1963.
