A.O.G. Wentworth No. 1: Palynological Report on Permian Sediments in the Murray Basin

A palynological report from Geoscience Australia, last updated in 2026, details the examination of cores and cuttings from the A.O.G. Wentworth No.1 well in New South Wales. It indicates the well passed from Tertiary into Lower Cretaceous and then into Lower Permian sediments, reaching a total depth of 2081 feet. The report also compares findings to samples from the Oaklands-Coorabin coalfield to establish age correlations with the Sydney Basin.

Use Cases

• Stratigraphic correlation based on palynological markers described in the report.
• Age determination of pre-Mesozoic sedimentary sections based on microfossil content.
• Comparative analysis of Permian coal measures between the Murray and Sydney Basins.
• Reconstruction of paleoenvironments in the Oaklands-Coorabin area during the Permian period.

Strengths

• Report provides specific depth intervals (e.g., 1283-1335 feet, 2081 feet total depth) for geological transitions.
• Includes comparative analysis with a second location (Oaklands-Coorabin coalfield) for age correlation.
• Originates from Geoscience Australia, a national geological survey.

Limitations

• Data is presented as a PDF/HTML report; column-level data and row counts are unknown.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Freshness should be verified despite the 2026 update date, as the underlying study is likely historical.
