Mentelle Basin Seismic and Geophysical Survey Data for Petroleum Prospectivity

In 2008-09, Geoscience Australia acquired 2,570 km of seismic, gravity, and magnetic data in the frontier Mentelle Basin. The data was used to map structures and assess petroleum potential, identifying an active petroleum system and multiple play types. The dataset originates from the 2010 Australian Government acreage release for the 36,000 m² basin located 150 km west of Cape Leeuwin.

Use Cases

• Assessing petroleum prospectivity based on identified source rocks, reservoirs, and seals.
• Mapping subsurface structures and supersequences based on interpreted seismic data.
• Evaluating play types such as faulted anticlines and stratigraphic traps described in the basin.
• Modeling basin geology and evolution using integrated seismic, gravity, and magnetic data.

Strengths

• Includes 2,570 km of industry-standard seismic data from a dedicated survey.
• Integrates multiple geophysical data types: seismic, gravity, and magnetic.
• Covers a large, defined frontier basin area of 36,000 m² with water depth context provided.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last metadata update was 2026-04-30 13:08:33.865994.
