For land seismic surveys, it is still commonly thought that switching from conventional to multicomponent acquisition merely requires replacing vertical receivers with 3C receivers. This may work in some but not all cases. Fortunately, when it doesn't, the situation may be rectified by accounting for the physics of PS-mode propagation. In fact, this is often the prerequisite for obtaining comparable resolution of P and PS reflections at the target level—the condition for obtaining full benefit from the combined use of P and PS data for determining appropriate exploration attributes and seismic inversion.

Two major properties of PS mode, that have...
