Borehole seismic information provides a more accurate measured velocity profile in certain areas. Accurate downhole information, although sparsely sampled in an area, can be co-krigged with surface data to provide a more robust areal velocity field, thus assisting the surface-seismic processing flow in stacking, DMO, and ultimately, depth migration.

Parameter selection of surface-seismic data processing flows using borehole seismic data falls into a number of broad categories.
