Abstract：Practical significance of application of P-VS converted waves in the shear wave method and in the P and S waves combination method are discussed, There are some special requirements during stages of acquisition, processing and interpretation, In general, converted waves are stronger around and beyond the critical angle. In view of the asymmetry of P-SV raypaths, a modified trace gathering scheme is proposed, The travel time curve for a P-SV wave is nearly hyperbolic,and the velocity derived therefrom takes .both .P and SV raypaths into account. This is a composite" velocity which will be used for NMO corrections the same way as those done for P-P wsves.
