Esso Bass Well Logs: Geological Survey of Bass Basin, Tasmania

Esso Bass No. 1 Well was drilled in 1965 to a depth of 7717 feet in the Bass Basin, about 88 miles east of King Island. The well was designed to test the petroleum potential of a postulated reef-type anomaly in the Miocene section and gain stratigraphic information on Tertiary and Mesozoic sediments. A full programme of logging and coring was undertaken by Esso Exploration Australia Inc.

Use Cases

• Analyze stratigraphic information based on the Tertiary and Mesozoic sedimentary section described
• Evaluate petroleum potential based on the postulated reef-type anomaly in the Miocene section
• Study well drilling and logging procedures based on the detailed operational timeline provided
• Map geological features based on the described location and basin area of approximately 25,000 square miles

Strengths

• Detailed operational timeline includes spud date (21 July 1965), total depth (7717 feet), and abandonment date (14 September 1965)
• Specific geographic context includes location (88 miles east of King Island) and basin area (approximately 25,000 square miles)
• Clear purpose statement: to test petroleum potential and gain stratigraphic information

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
