Bremer Sub-basin Geology and Petroleum Potential Study

A 2004 study by Geoscience Australia assessed the petroleum potential of the deep-water Bremer Sub-basin offshore southwestern Australia. The frontier area, with water depths from 100 to 4000 meters, had no wells drilled and relied on a 1974 regional seismic survey by Esso Australia Ltd. The study aimed to determine if geological conditions were suitable for generating and trapping hydrocarbons.

Use Cases

• Evaluating hydrocarbon trap potential based on described Middle Jurassic-Early Cretaceous half-graben structures.
• Assessing frontier exploration risk based on the lack of sub-surface geological data and deep-water setting.
• Planning regional seismic survey strategies based on the historical 1974 survey mentioned.
• Studying geological basin evolution based on the described Jurassic-Cretaceous timeframe.

Strengths

• Focuses on a specific frontier area, the Bremer Sub-basin, with defined water depths of 100-4000 meters.
• Provides historical context with a specific seismic survey date (1974) and study commencement date (2004).
• Identifies a specific geological timeframe for basin formation: Middle Jurassic-Early Cretaceous.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
