PS to PP time mapping is one of key factors affecting seismic reservoir predictions in multicomponent seismic interpretations. Based on prior work

a new method is presented for the ratio of compressional velocity and shear velocity scanning and PS to PP reflection time mapping with using convertedwave prestack data. Model data results show that convertedwave velocity

the ratio of compressional velocity and shear velocity can be obtained directly from convertedwave seismic gathers

and P wave and PS wave reflection time can be automatically matched by means of the method presented. It works well with model data

suits for multicomponent seismic data processing in an area with horizontal formation.
