Combining seismic data in a joint processing has several interests as complementary information and constrains on the sub-surface are available. For instance, surface and borehole seismic data integrated in joint tomography lead to intrinsic well-tie of reflection seismic, and allow anisotropy estimation. Joint tomography of reflected and refracted arrivals better determines near-surface models and consequently improves deep imaging. Accounting for reflections, diffractions plus transmissions in cross-hole tomography increases the resolution of velocity models.
