• Contains major structural boundary
Korsch and Doublier 2016
• But southern area
Motivation and background
– 2 km E-W
– 5 km N-S
– 500 m E-W
– 5 km N-S
– Limited drilling
Basin study
Basin study
Synthetic modelling
Basin study
• Basement poorly resolved
• Resistive lower basin unit added
Basin study
estimation
• Starting/prior model
Synthetic modelling outcomes
• Basement unable to be reliability determined
• Pre-existing basement surface can be validated
qualitatively
Basin study
• Minimal structure indicated
• Very large dataset
• Four testing suites • Starting model • smoothing • data component
• data spacing
• Highly variable inversion results
Coarse inversion
Variability analysis
Crustal study
• C2 feature highly variable
• Extent of C3 variable
• Detailed analysis of variability time consuming but useful
• Subtle data features = high inversion variability?
