- W2357403009 abstract "Spectral decomposition of PP-and PS-wave data using matching pursuit decomposition(MPD)has better resolution on both time and frequency,and maintains consistency across the entire time-frequency plane.Comparing to Fourier transform method,the MPD algorithm avoids choosing the size of window and dose not show temporal smearing of frequencies.PP-waves attenuate more than PS-waves when going through a gas reservoir,which gives rise to a noticeable low-frequency amplitude shadow on the PP-wave common frequency section beneath the gas reservoir.There exists no such a shadow on the PS-wave common frequency section.Thus we can predict gas-bearing potentials by investigating the behaviors of seismic waves on the both kinds of common frequency sections.The proposed method was verified on a real multi-component data set from northeaster China." @default.
