Mentelle Basin Seismic and Geophysical Survey Data for Petroleum Prospectivity

Geoscience Australia acquired 2,570 km of industry-standard seismic, gravity, and magnetic data in 2008-09 for the frontier Mentelle Basin. This data underpins a petroleum prospectivity assessment, mapping structures and supersequences across the 36,000 m² basin located 150 km west of Cape Leeuwin. The assessment suggests the basin contains at least one active petroleum system with multiple potential source rocks, reservoirs, and seals.

Use Cases

• Evaluate petroleum prospectivity based on mapped seismic structures and supersequences.
• Model basin geology based on interpreted seismic, gravity, and magnetic data.
• Identify hydrocarbon play types based on described faulted anticlines, stratigraphic, and unconformity plays.
• Assess source rock and reservoir potential based on described intervals of coals, carbonaceous shales, and fluvial/marine strata.

Strengths

• Includes 2,570 km of industry-standard seismic data.
• Covers a large, defined sedimentary basin of 36,000 m².
• Data collection was purpose-driven for a specific petroleum prospectivity assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats beyond HTML are unknown, which may limit suitability assessment.
• Freshness should be verified; metadata indicates a last update of 2026-04-20.
