Mentelle Basin Seismic and Geophysical Survey Data

Geoscience Australia acquired 2570 km of industry-standard seismic, gravity, and magnetic data in 2008-09 to assess petroleum prospectivity in the frontier Mentelle Basin. The survey mapped structures and supersequences across the 36,000 m2 basin, located west of Cape Leeuwin. This work suggested the basin contains at least one active petroleum system with potential for multiple source rocks, reservoirs, and seals.

Use Cases

• Map basin structures and supersequences using the 2570 km of interpreted seismic data.
• Assess petroleum prospectivity by analyzing identified play types like faulted anticlines and sub-basalt fault blocks.
• Model potential source rock intervals and reservoir seals using data on coals, carbonaceous shales, and fluvial/marine strata.
• Correlate geological features with water depth data ranging from 500-1500 m on the slope to 4000 m in the Naturaliste Trough.

Strengths

• 2570 km of industry-standard seismic data acquired
• Interpretation mapped main structures and supersequences across a 36,000 m2 basin
• Survey collected complementary gravity and magnetic data

Limitations

• Specific data formats, column definitions, and sample data are unavailable
• Dataset size, row count, and exact file structure are unknown
• Data originates from a single survey in 2008-09, potentially lacking temporal updates
