Claim:
1. A method of geological medium exploration comprising: generating vibrations in a geological medium; recording wave-fields at a surface; obtaining borehole spectral characteristics; calculating a wave-field modification operator based at least in part on the recorded wave-fields and borehole spectral characteristics; and applying the wave-field modification operator to a full range of seismic data to achieve a spectrally-modified wave field, wherein calculating the wave-field modification operator comprises: calculating a Fourier transformation of a seismic route x(t); calculating a Fourier transformation of a route of reflection coefficients r creating an amplitude spectrum product; creating a sum of phase spectra; receiving a complex amplitude and phase spectrum; and performing a reverse Fourier transformation on the complex spectrum to create a time function X(t).
