Esso Bass Wells: Drilling Summary and Geological Report for Bass Basin, 1965

Esso Exploration and Production Australia Inc. drilled the Esso Bass No. 1 and No. 2 wells in the offshore Bass Basin in 1965. The report details the drilling of Esso Bass No. 1, which reached a total depth of 7717 feet and was plugged and abandoned in September 1965. It also describes the geological context of the 25,000 square mile Bass Basin and the well's objective to test the petroleum potential of a Miocene reef-type anomaly.

Use Cases

• Analyzing historical offshore drilling operations based on the detailed spud and completion dates.
• Studying the Tertiary and Mesozoic sedimentary geology of the Bass Basin based on the described stratigraphic objectives.
• Evaluating historical petroleum exploration targets based on the description of a postulated Miocene reef-type anomaly.
• Researching the geological interpretation of the Bass Basin based on the mentioned magnetic and seismic data.

Strengths

• Report includes specific factual details such as the well depth of 7717 feet and precise drilling dates in 1965.
• Provides geological context for the 25,000 square mile Bass Basin and the specific exploration target.

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.
