Inverse -filter for seismic resolution enhancement

Y Wang - Geophysics, 2006 - library.seg.org
A principal limitation on seismic resolution is the earth attenuation, or Q-effect, including the
energy dissipation of high-frequency wave components and the velocity dispersion that …

[图书][B] Seismic inversion: Theory and applications

Y Wang - 2016 - books.google.com
Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by
solving an inverse problem based on seismic measurements. There are at least three …

Sparse reflectivity inversion for nonstationary seismic data

X Chai, S Wang, S Yuan, J Zhao, L Sun, X Wei - Geophysics, 2014 - library.seg.org
Conventional reflectivity inversion methods are based on a stationary convolution model
and theoretically require stationary seismic traces as input (ie, those free of attenuation and …

Inverse- filtered migration

Y Wang - Geophysics, 2008 - library.seg.org
An inverse-Q filtered migration algorithm performs seismic migration and inverse-Q filtering
simultaneously, in which the latter compensates for the amplitudes and corrects the phase …

Q factor estimation from the amplitude spectrum of the time–frequency transform of stacked reflection seismic data

WM Lupinacci, SAM Oliveira - Journal of Applied Geophysics, 2015 - Elsevier
Attenuation is one factor that degrades the quality of reflection seismic subsurface imaging. It
causes a progressive decrease in the seismic pulse energy and is also responsible for …

The Ricker wavelet and the Lambert W function

Y Wang - Geophysical Journal International, 2015 - academic.oup.com
The Ricker wavelet has been widely used in the analysis of seismic data, as its asymmetrical
amplitude spectrum can represent the attenuation feature of seismic wave propagation …

Q factor estimation based on the method of logarithmic spectral area difference

S Wang, D Yang, J Li, H Song - Geophysics, 2015 - pubs.geoscienceworld.org
We have developed a novel method for Q estimation. As a seismic wave propagates through
subsurface viscoelastic media, seismic attenuation decreases the amplitude and reduces …
