Geology of the Birdsville 4-Mile Sheet Area in Queensland

A geological report on the Birdsville 4-mile sheet area in Queensland, Australia, published by the Australian Ocean Data Network. The mapping established a sequence of at least 3,000 feet of Mesozoic sediments and a maximum of 100 feet of Tertiary rocks. The report identifies aquifer formations, potential petroleum source rocks, and reservoir sandstones within the western Great Artesian Basin.

Use Cases

• Model groundwater aquifers based on the described Mesozoic rock sequences and impermeable cap.
• Assess petroleum source rock potential based on the described marine shales of the Wilgunya Formation.
• Identify reservoir rock locations for hydrocarbon exploration based on the sandstones of the Lower Cretaceous Longsight Sandstone.
• Map regional geological structures and stratigraphy for the western Great Artesian Basin.

Strengths

• Report includes specific geological thickness measurements, such as at least 3,000 feet of Mesozoic sediments and a maximum of 100 feet of Tertiary rocks.
• Identifies specific geological formations with functional attributes, such as the main aquifer, impermeable cap, and potential source/reservoir rocks.
• Provides spatial context with references to specific locations like the Bedourie Bore and Delhi Frome Santos Betoota No. 1 Well.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a specific Queensland sheet area.
