Quality factor estimation based on the peak frequency shift method using a robust Fourier transform to VSP data

R Sandoval, JL Paredes, FA Vivas - Journal of Geophysics and …, 2019 - academic.oup.com
Quality factor estimation (Q estimation) of vertical seismic profile (VSP) data are necessary
for the process referred to as inverse Q-filtering, which is used, in turn, to improve the …

Regularized inversion of amplitude-versus-incidence angle (AVA) based on a piecewise-smooth model

Z Li, M Wang, F Xu - Acta Geophysica, 2018 - Springer
Different from the stacked seismic data, pre-stack data includes abundant information about
shear wave and density. Through inversing the shear wave and density information from the …
