6. Fundamentals of Inversions

Here, we explain geophysical inversion and describe the parameters which impact inversion results. To demonstrate the impact of each parameter, we invert synthetic magnetic survey collected over a susceptible block within a half-space.

• 6.1. Basic concept
• 6.2. The objective function
• 6.3. Data uncertainties
• 6.4. The Beta parameter (trade-off)
• 6.5. The alphas parameters
• 6.6. The weighting matrices
• 6.7. Sparse and blocky norms
• 6.8. Reference model in the smoothness Term
• 6.9. Data weighting and joint inversion
