On the problem of mapping deep cracked zones by using seismic observations

The problem of conversion of a slow wave propagating in a cracked collector into a tube wave in a borehole intersecting the collector is considered. The influences of the collector's porosity and of the parameters of the background medium on the dynamics of the tube wave are investigated. It is demonstrated that the elastic response of the medium to the wave incident on the borehole consists of a propagating and a diffusive field.
