Marine Seismic Survey Data from Capricorn and Northern Tasman Basins

A marine multi-channel seismic reflection survey acquired 2900 km of data over the Capricorn Basin and northern Tasman Basin margins in 1989. The dataset investigates basin structure, stratigraphy, and petroleum potential, integrating sonobuoy refraction, gravity, magnetic, and bathymetric data. It includes seismic ties to the Aquarius-1 and Capricorn-1A wells.

Use Cases

• Analyze seismic reflection data to model Late Cretaceous to Recent stratigraphy and basin development in the Capricorn Basin.
• Correlate sonobuoy refraction and gravity data with seismic profiles to refine subsurface structural interpretations.
• Integrate magnetic and bathymetric data for a multi-geophysical assessment of the continental margin's petroleum resource potential.
• Use the seismic ties to the Aquarius-1 and Capricorn-1A wells to calibrate and validate seismic sequence interpretations.

Strengths

• Covers 2900 km of acquired seismic data, providing substantial spatial coverage.
• Integrates multiple geophysical data types: seismic reflection, sonobuoy refraction, gravity, magnetic, and bathymetry.
• Includes critical calibration points via seismic ties to the only two deep offshore wells in the region.

Limitations

• Primary seismic data is from a single 1989 survey, with the prior survey dating to 1974, creating a temporal gap.
• Data is presented in HTML format, which is not a standard, machine-readable format for geophysical analysis and requires extraction.
• Specific technical details like row counts, column structures, and file sizes for the underlying data are unknown.
