Lower Cretaceous Foraminifera Analysis from a Queensland Well

A 2026 report from the Australian Ocean Data Network details the lithology and foraminiferal species from the Phillips-Sunray Buckabie No. 1 well in Queensland. It examines cuttings from 80 to 3,310 feet and three specific core intervals to define the Lower Cretaceous sequence in the Great Artesian Basin. The study uses the first appearance of foraminiferal species and Inoceramus prisms to determine the geological section.

Use Cases

• Identify the first appearance datum of specific foraminiferal species like Inoceramus prisms to establish biostratigraphic zones.
• Correlate lithological descriptions from cuttings and cores with microfossil assemblages to interpret depositional environments.
• Use depth intervals (e.g., 1,123'-1,136' for Core 1) to construct a detailed stratigraphic column for the Lower Cretaceous in this basin.

Strengths

• Report examines a continuous section from 80 to 3,310 feet, providing depth-specific data.
• Analysis includes three discrete core samples (e.g., Core 8 at 5,518'-5,537') for detailed examination.

Limitations

• Primary data is locked in a PDF/HTML report format, requiring manual extraction for computational analysis.
• Sample is from a single well location, limiting regional geological generalizations.
• The dataset's age and specific microfossil count or measurement tables are not explicitly detailed.
