A geological survey of the Birdsville 4-mile sheet area in Queensland established a sequence of at least 3,000 feet of Mesozoic sediments. The data, from Geoscience Australia, describes the main aquifer and cap rock of the western Great Artesian Basin and assesses potential petroleum source and reservoir rocks. The record was last updated on 2026-05-14.
Use Cases
- Model groundwater flow based on described aquifer and impermeable cap rock characteristics.
- Assess petroleum prospectivity based on identified source rocks in the Wilgunya Formation and Lower Palaeozoic sequence.
- Map regional stratigraphy using the described sequence of Mesozoic and Tertiary sediments.
- Evaluate reservoir potential based on the sandstones of the Lower Cretaceous Longsight Sandstone.
Strengths
- Describes a sedimentary sequence of at least 3,000 feet with quantified thicknesses.
- Identifies specific geological formations with potential economic significance (e.g., Wilgunya Formation, Longsight Sandstone).
- Provides spatial context with references to specific boreholes and distances from Birdsville.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
