The conversion of VSP data into offset-depth domain can be achieved by either VSP CDP stacking or migration techniques. But conventional seismic migration techniques can hardly bring desirable VSP migration result because VSP data usually appear as common-shotpoint gather and contain less data volume. Kirchoff integral algorithm is extendedly applied in this paper to variant-velocity prestack migration of VSP data. The key to applying Kirchhoff integral algorithm to VSP data lies in determining Kirchhoff locus, which is equivalent to determining an isochronous locus whose foci are at the source point and the receiving point.
