Checkshots and vertical seismic profiles - AAPG Wiki
A vertical seismic profile (VSP) is recorded in essentially the same way as a checkshot survey. The major difference between a VSP and a checkshot survey is that VSP data are recorded at much smaller spatial sampling intervals than checkshots. While a receiver may be moved a vertical distance of 200. 60.96 m. to 1000 ft.

Synthetic seismogram - AAPG Wiki
A synthetic seismogram is the fundamental link between well data and seismic data, and it is the main tool (along with a vertical seismic profile [VSP], if available) that allows geological picks to be associated with reflections in the seismic data. As discussed, if a VSP is available for a particular well, a synthetic is not needed.
