Esso Bass Well Data: Stratigraphic and Petroleum Potential Analysis, 1965

Geoscience Australia Data provides a summary report for the Esso Bass No. 1 and No. 2 wells drilled in the offshore Bass Basin. The document details the drilling of Esso Bass No. 1 in 1965, which reached a total depth of 7717 feet, and the geological objectives to test the petroleum potential of the Tertiary and Mesozoic sedimentary sections. The data is presented in PDF and HTML formats.

Use Cases

• Analyzing stratigraphic information for the Tertiary and Mesozoic sections based on the well's stated objective.
• Studying historical offshore drilling operations and logging programs based on the described activities.
• Evaluating the petroleum potential of reef-type anomalies in the Miocene section as mentioned in the description.
• Mapping the sedimentary geology of the Bass Basin using data inferred from magnetic and seismic surveys.

Strengths

• Report includes specific operational details such as spud date (21 July 1965), total depth (7717 feet), and plugging date (14 September 1965).
• Describes a full program of logging and coring, suggesting detailed subsurface data collection.
• Provides geological context for the Bass Basin, including its approximate area of 25,000 square miles and inferred sedimentary thickness.

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.
