Lower Cretaceous Foraminifera from a Queensland Well, 80 to 3,310 Feet

Phillips-Sunray Buckabie No.1 Well was drilled to a depth of 9,070 feet, 29 miles north of Quilpie in southwestern Queensland. This report examines cuttings from 80 to 3,310 feet, considered the base of the marine Lower Cretaceous, and includes analysis of three specific core intervals. The study of lithology and the first appearance of foraminiferal species and Inoceramus prisms determined a section of the Lower Cretaceous sequence in this part of the Great Artesian Basin.

Use Cases

• Establish biostratigraphic zonation based on the first appearance of foraminiferal species mentioned in the description
• Correlate lithological units with fossil assemblages from the described well cuttings and cores
• Reconstruct paleoenvironmental conditions for the Lower Cretaceous in the southwestern Great Artesian Basin
• Calibrate regional geological models using the determined Lower Cretaceous sequence section

Strengths

• Report is based on analysis of cuttings from a 3,230-foot interval (80 to 3,310 feet) and three specific core samples
• The well provides a localized but detailed vertical sequence for the Lower Cretaceous in a defined geographic area
• Study integrates lithological examination with specific paleontological markers like Inoceramus prisms

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 reports, not in a structured, machine-readable format
