Attenuation in seismic data is governed by energy loss per oscillation over a given travel time. High frequencies exhibit higher level of oscillation and are more prone to attenuation.

Using the VSP downgoing wavefield recorded at successive depths in the borehole, it is possible to estimate the decay of high frequencies with depth. The frequency decay estimate can then be inversely applied to surface seismic data to restore lost bandwidth.
