Mentelle Basin Frontier Exploration Data with Seismic and Geophysical Surveys

Geoscience Australia acquired 2570 km of seismic data in 2008-09 to assess the petroleum prospectivity of the frontier Mentelle Basin. This large sedimentary basin, covering 36,000 m2 and located 150 km west of Cape Leeuwin, was first offered for acreage release by the Australian Government in 2010. Interpretation of the seismic, gravity, and magnetic data mapped structures and supersequences, confirming the basin's potential for an active petroleum system with multiple play types.

Use Cases

• Model basin geology and structure based on mapped supersequences and main structures.
• Assess petroleum prospectivity based on identified source rock intervals, reservoirs, and seals.
• Evaluate exploration play types such as faulted anticlines and stratigraphic plays described in the basin.
• Analyze geophysical characteristics using the acquired seismic, gravity, and magnetic data.

Strengths

• Includes 2570 km of industry-standard seismic data from a dedicated survey.
• Covers a large, defined geographic area of 36,000 m2 with water depth ranges from 500 to 4000 m.
• Interpretation led to concrete geological mapping and identification of multiple petroleum play types.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in HTML format, which may not be directly machine-readable for analysis.
