Abstract

The Virtual Source (VS) is a kind of Seismic Interferometry and synthesizes a new seismic record whose source comes from a receiver location by processing cross-correlation to plural records. We make experiments in the laboratory and simulations in order to synthesize a VS data from records between cross-holes, and confirm this data can be used for cross-hole tomography. By comparison with experiments, we make numerical simulation whose source is in the borehole1, and receivers are in boreholes2. In the cross-correlation results of experiments, we successfully synthesized the new records, which can be clearly picked up the positions of first motions of waves. This result indicates the validity of the VS method for applying the geotomography. In the next stage, we will try the experiment and simulation on the more complex model and measure the field data for improving the practicality of this method.
