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

Beach Petroleum No Liability drilled the Geltwood Beach No. 1 Well in the Otway Basin, South Australia, in 1963. The well reached a total depth of 12,300 feet and recorded stratigraphic data, gas traces, and test results over a 2.5-month drilling period. This dataset, sourced from the Australian Ocean Data Network, summarizes the geological findings and hydrocarbon potential assessment of the dry hole.

Use Cases

• Analyze stratigraphic sequences and sediment thicknesses based on the described Miocene to Cretaceous layers.
• Model hydrocarbon potential and subsurface structure based on recorded gas traces and drillstem test results.
• Study the geological history of the Otway Basin based on the detailed sediment descriptions and formation groups.
• Benchmark historical drilling operations and subsidized exploration projects based on the dates, depth, and subsidy act mentioned.

Strengths

• Provides precise operational details including total depth (12,300 feet) and exact drilling dates (August 22 to November 10, 1963).
• Contains specific stratigraphic measurements, such as 45 feet of Recent sand and 1860 feet of Miocene to Eocene sediments.
• Documents a full program of logging, testing, and coring, suggesting structured data collection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a single, historical location and time period, which may limit generalizability.
