- W2009178241 abstract "Summary In this paper, we propose a novel method for Q estimation. As we all know, attenuation decreases the amplitude and reduces the bandwidth, which causes the variation of the logarithmic spectral area of seismic wave. According to this property, we derive an analytical relation between Q factor and the logarithmic spectral area-difference of seismic wave. Tests of the method on synthetic models (1D attenuation model and zero-offset VSP model) and the real zero-offset VSP data show that our method can accurately estimate Q factor and it is insensitive to noise. Considering this, further research can extend the proposed method to reflection seismic data for Q estimation by introducing the time-frequency analysis techniques." @default.
