Geltwood Beach No. 1 Well: Drilling Log and Stratigraphy from the Otway Basin, 1963

South Australia's Otway Basin contains data from the Geltwood Beach No. 1 well, drilled in 1963 to a depth of 12,300 feet. Beach Petroleum No Liability commissioned the well to test hydrocarbon potential, with a full program of logging, testing, and coring. The well was plugged and abandoned as a dry hole after finding only traces of gas and salty water.

Use Cases

• Model subsurface stratigraphy based on described sediment sequences from Recent to Lower Cretaceous.
• Analyze hydrocarbon exploration outcomes based on drillstem test results yielding gas-cut water.
• Study geological structure evolution based on data from a well drilled on the Geltwood Anticline.
• Correlate regional sediment wedge-outs using evidence from nearby Mount Salt and Beachport wells.

Strengths

• Contains specific drilling dates (22 August 1963 to 10 November 1963) and total depth (12,300 feet).
• Description includes detailed stratigraphic intervals (e.g., 1860 feet of Miocene to Eocene sediments).
• Documents a full program of logging, testing, and coring undertaken during the operation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single, historical well drilled in 1963.
