A complex screen propagator for elastic waves is used in multicomponent seismic migration and imaging. Imaging conditions for both P-P imaging and P-S converted wave imaging are proposed to handle polarizations of the data. The propagators and imaging conditions are tested with numerical examples.
Multicomponent data increased the information of seismic data. Recent developments of ocean bottom seismic (OBS) technology make more multicomponent data available. From these data, both P-P and P-S sections can be obtained. Since these waves carry different properties of the target reflectors, combining them together can provide us with petrophysical parameters that cannot be obtained with P-wave data alone.
