Structurally consistent amplitude Q compensation using tau-px-py inversion

Absorption effects in the Earth attenuate high frequency seismic signal progressively with depth, reducing resolution and limiting the interpretability of the data. Conventional post-migration Q compensation methods often rely on artificial mechanisms to limit amplification of noise, at the expense of unintentionally restricting recovery of signal. We propose an amplitude Q compensation technique using 3D sparse inversion. Comparisons with a conventional approach on synthetic and field datasets highlight improved signal recovery and noise suppression with the proposed method.
