Bass Basin Well Summary: Stratigraphic and Petroleum Potential Data

July to September 1965 drilling data from the Esso Bass No. 1 and No. 2 wells in the offshore Bass Basin. The dataset, provided by the Australian Ocean Data Network, documents a full program of logging and coring from wells drilled to a depth of 7717 feet. It was designed to gain stratigraphic information on the Tertiary and Mesozoic sections and test the petroleum potential of a Miocene reef-type anomaly.

Use Cases

• Analyze stratigraphic sequences based on described Tertiary and Mesozoic sedimentary sections.
• Assess petroleum generation and accumulation potential based on the described geological inferences.
• Study offshore drilling operations and logging programs from the 1960s based on the detailed well timeline.
• Model basin geology based on the described magnetic and seismic data interpretations.

Strengths

• Detailed historical timeline including spud date (21 July 1965) and total depth (7717 feet).
• Specific geographic context covering an area of approximately 25,000 square miles in the Bass Basin.
• Clear stated objective to test a postulated Miocene reef-type anomaly.

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 data_gov_au.
