WebSeismic inverse Q filtering is a data processing technology for enhancing the resolution of seismic images. It employs a wave propagation reversal procedure that compensates for energy absorption and corrects wavelet distortion due to velocity dispersion. By compensating for amplitude attenuation, seismic data can provide true relative-amplitude … WebNov 23, 2024 · The proposed oriented pre-stack inverse Q filtering method is velocity-independent and suitable for a depth varying Q model.

WebInverse Q -filter for seismic resolution enhancement. A principal limitation on seismic resolution is the earth attenuation, or Q -effect, including the energy dissipation of high … WebFeb 1, 2024 · Abstract Accurate estimation of seismic quality factor (Q) is important in seismic data processing to correct for the velocity dispersion effects and to compensate for absorption losses through inverse Q filtering. To estimate it, often logarithmic spectral ratios of the non-stationary seismic signal between two depth levels are linearly inverted.
