Bremer Sub-basin Geology and Petroleum Potential, Offshore Southwestern Australia

The Bremer Sub-basin is a deep-water frontier area in the Bight Basin off the southern coast of Western Australia. Geoscience Australia's study, which commenced in 2004, aimed to determine if the sub-basin formed under suitable geological conditions to generate and trap large volumes of hydrocarbons. The dataset includes information from a regional seismic survey conducted in 1974 and analysis of Middle Jurassic-Early Cretaceous structures.

Use Cases

• Assessing hydrocarbon trap potential based on identified Middle Jurassic-Early Cretaceous half-graben structures.
• Evaluating exploration risk in deep-water settings based on water depth ranges from 100 to 4000 meters.
• Planning frontier exploration strategies based on the 1974 regional seismic survey data.
• Studying the geological evolution of the Bight Basin based on the sub-basin's structural history.

Strengths

• Focuses on a key frontier area identified by Geoscience Australia's New Oil Program in 2003.
• Includes data from a specific regional seismic survey conducted by Esso Australia Ltd in 1974.
• Covers a defined deep-water setting with water depths between 100 and 4000 meters.

Limitations

• No wells have been drilled to test the sub-basin's petroleum potential, limiting subsurface validation.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset's primary exploration data is from 1974, with a significant gap until the study commenced in 2004.
