Abstract

Summary

By extending the low-frequency content, broad-band seismic data lessens the dependence of seismic inversion on a background model. Despite that, the merging of the inverted seismic with a very low frequency background model poses a new problem: the duration of a well-log synthetic seismogram is often seriously inadequate for defining the sharp spectral decay to zero frequency. To address this issue, a practical approach based on multi-taper spectral analysis is proposed to determine the low-frequency spectral decay of the seismic well tie wavelet. Furthermore the impact on seismic inversion is demonstrated.
