Esso Gippsland Shelf No. 1 was Australia's first offshore well, drilled by Esso Exploration Australia, Inc. The well was spudded on December 27, 1964, reached a total depth of 8701 feet on May 31, 1965, and was completed as a suspended gas well on June 5, 1965. The stratigraphic drilling operation was subsidized under the Petroleum Search Subsidy Act 1959-1964.
Use Cases
- Analyze hydrocarbon shows and production tests based on detailed test results and flow rates mentioned in the description
- Study stratigraphic sequences based on the Tertiary and Upper Cretaceous sections penetrated by the well
- Evaluate historical offshore drilling operations based on the vessel and drilling timeline details
- Assess gas column productivity based on the logged 353-foot gas column in the Eocene Latrobe Valley Coal Measures
Strengths
- Contains precise drilling dates and depths, including spud date (1964-12-27) and total depth (8701 feet)
- Includes detailed production test results with specific gas flow rates (e.g., 6.85 MMcf/D) and condensate volumes
- Documents significant geological discoveries, such as the first offshore discovery in Australia and first porous sandstone in the Gippsland Limestone
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
