Bass Basin Offshore Well Drilling Summary And Geological Analysis

July to September 1965 covers the drilling period for the Esso Bass No. 1 well in the Tasmanian waters of the Bass Basin. The dataset is a summary report detailing the well's operational timeline, total depth, and the geological objectives for exploring the basin's petroleum potential. It was created by the Australian Ocean Data Network, aggregating information from Esso Exploration and Production Australia Inc.

Use Cases

• Analyze drilling timeline and operational details like spud date and total depth for well performance benchmarking.
• Study the inferred thick sedimentary section and postulated Miocene reef-type anomaly for geological modeling.
• Correlate magnetic and seismic data interpretations with actual well stratigraphic information to validate basin models.
• Assess the petroleum potential of Tertiary and Mesozoic sediments in the north central Bass Basin based on well results.

Strengths

• Report provides specific operational dates (21 July 1965 to 14 September 1965) and a precise total depth of 7717 feet.
• Covers a defined geographical area of approximately 25,000 square miles in the Bass Basin.
• Documents a full programme of logging and coring undertaken for the well.

Limitations

• Dataset consists of summary report text in PDF/HTML format, not structured tabular data for direct analysis.
• Limited to a single well (Esso Bass No. 1) and its immediate context, offering a narrow sample size.
• Historical data from 1965 may not reflect current geological understanding or exploration technologies.
