Geltwood Beach No. 1 Well: Drilling and Stratigraphic Data from Otway Basin, 1963

1963 drilling data from the Geltwood Beach No. 1 well in South Australia's Otway Basin. The well was drilled to a depth of 12,300 feet between August and November 1963 by Beach Petroleum No Liability to test hydrocarbon potential. A full program of logging, testing, and coring was undertaken, recording stratigraphic sequences and traces of gas.

Use Cases

• Model subsurface stratigraphy based on described sediment sequences from Recent to Cretaceous.
• Analyze hydrocarbon exploration outcomes based on drillstem test results and gas trace records.
• Study the geological history of the Otway Basin based on the detailed stratigraphic column.
• Assess drilling operations and subsidized exploration under the Petroleum Search Subsidy Act.

Strengths

• Detailed operational timeline with specific start (22nd August 1963) and completion (10th November 1963) dates.
• Precise depth measurements provided, including total depth (12,300 feet) and layer thicknesses (e.g., 45 feet of Recent sand).
• Comprehensive data collection program described, including logging, testing, and coring.

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 geographic/temporal bias inherent to a single exploratory well from 1963.
