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

Palynological examination of cores and cuttings from the A.O.G. Wentworth No.1 well indicates a transition from Tertiary into Lower Cretaceous marine sediments between 1283-1335 feet or 140-1455 feet, and into probable Lower Permian beds at 1615-1645 feet. The well was completed in conglomerates, likely also Lower Permian, at a total depth of 2081 feet. This report from the Australian Ocean Data Network compares these findings with samples from the Oaklands-Coorabin coalfield to establish age correlations with the Upper Coal Measures of the Sydney Basin.

Use Cases

• Correlating stratigraphic layers between wells based on palynological markers mentioned in the description.
• Dating sedimentary sequences in the Murray Basin based on identified microfossil content.
• Studying the transition from marine to terrestrial environments in the Permian period as suggested by the sediment analysis.
• Comparing the age of coal measures in the Oaklands-Coorabin field with the Sydney Basin's Upper Coal Measures as described.

Strengths

• Provides specific depth intervals (e.g., 1283-1335 feet, 1615-1645 feet) for geological transitions.
• Includes comparative analysis with a second location (Oaklands-Coorabin coalfield) for age correlation.
• Report is hosted by an authoritative organization, the Australian Ocean Data Network.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML report format, not as structured, machine-readable data.
