Abstract

The quality of receiver-to-ground coupling can be highly variable in surface, surface-to-borehole, and crosshole seismic experiments. Poor coupling can affect the recorded seismic traces in a major way. Ignoring variable coupling conditions can lead to severe problems when waveform inversions are attempted. To address such problems, we have developed a novel scheme that estimates medium properties and frequency-dependent source functions and frequency-dependent receiver-coupling factors. We demonstrate the efficacy of the new scheme via a synthetic crosshole experiment in which realistic receiver-coupling factors are simulated.
