SEISMIC INVERSE Q FILTERING

When seismic waves propagate through the earth subsurface, the absorptionand dispersion effects will cause attenuation of wave amplitudes and shapedistortion of seismic waveforms. Inverse Q filtering is a wave propagation-reversal processing that removes these effects from recorded seismic data.After inverse Q filtering, seismic data will have improved quality withcorrect amplitudes and phases, which will result in better matching with thewell-log information, higher resolution for thin-layer interpretation andreliable seismic inversion for reservoir characterization
