Abstract In order to tackle the problem of complex overburden formation, R. Calvert and A Bakulin of Shell developed the virtual source method, which can solve the problem of building accurate velocity model. In this paper, the authors have dealt with the principle of virtual source, made a comparison with the crosswell seismic technology, and described its application in such aspects as time-lapse monitoring, imaging and virtual-shear wave. The results can provide some guidance for the understanding of this method.
