Browse Basin Deep Seismic Survey Proposal: 3200 km of Geophysical Lines

A cruise proposal outlines plans to acquire deep seismic and geophysical data over the Browse Basin region of Australia's North West Shelf. The survey aims to collect up to 3600 km of data along 11 lines, tying into 18 exploration wells and previous surveys. The project is part of AGSO's regional research program to determine the basin's structural framework and tectonic history.

Use Cases

• Modeling deep crustal structure based on seismic reflection data down to 8-12 seconds two-way time
• Analyzing tectonic and subsidence history based on the proposed regional structural framework assessment
• Assessing hydrocarbon accumulation influences based on the study of deep structure and reactivation
• Correlating seismic data with existing exploration wells based on the survey's plan to tie 18 wells

Strengths

• Survey parameters are detailed, including a 4800 m streamer, 192 active groups, and dual airgun arrays with 49 litre capacity
• The proposal specifies a planned acquisition of about 3200 km of data along 11 lines
• The methodology is consistent with previous AGSO surveys, which recorded reflections down to 12-20 km depth

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
