Seismic inverse Q filtering is a data processing technology for enhancing the resolution of reflection seismology images.
Q is the anelastic attenuation factor or the seismic quality factor, a measure of the energy loss as the seismic wave moves.
Seismic inverse Q-filtering employs a wave propagation reversal procedure that compensates for energy absorption and corrects wavelet distortion due to velocity dispersion.
By compensating for amplitude attenuation with a model of the visco-elastic attenuation model type, seismic data can provide true relative-amplitude information for amplitude inversion and subsequent reservoir characterization.
By correcting the phase distortion due to velocity dispersion, seismic data with enhanced vertical resolution can yield correct timings for lithological identification.
It is necessary that the initial U(r,w) either is already created by a forward synthetic Q-filtering process or taken directly from seismic surface data.
To obtain a solution that can be applied to seismic k(w) must be connected to a function that represent the way U(r,w) propagates in the seismic media.
The Kolsky Model is used extensively in seismic inverse Q-filtering.
