Abstract:
1. A method for use with a data processing system, for seismically assessing features of a volume of the earth using at least 3-component (3-C) Vertical Seismic Profiling (VSP)data, the method comprising: acquiring from at least one predetermined position within a volume of earth a set of at least 3-C VSP data representing effects of a seismic event occurring within the region of said volume, the VSP data characterized by at least time, position, and amplitude; computing at least one resonance spectrum indicating resonance scattering of the at least 3-C VSP data, said computing comprising dividing a plurality of transverse amplitude spectra components by a radial amplitude spectra component; using a processor to process the VSP data to interpret a lateral discontinuity of said features in accordance with the at least one resonance spectrum, and causing data related to the interpretation of the lateral discontinuity to be displayed on a computer interface screen in human interpretable form.
