Spectral-ratio (SR) methods for estimating the quality factor (Q) from post-stack seismic data often suffer from numerical instability and are highly sensitive to noise. We propose a robust interval-Q inversion method based on Q-scanning and spectral matching. The method consists of three key steps. First, stationary...

Conventional Kirchhoff migration is commonly affected by limited resolution, reflector broadening, and sidelobe contamination. Here, we propose DSVD-IHCM, a migration-imaging method that uses singular-value decomposition-based damped inverse Hessian compensation. The method first constructs local point-spread functions...
