The data obtained from well logs and surface seismic profiles have opposite but complementary characteristics. The first are very precise in depth, but they measure only the local physical properties; the second have a lower resolution, but sample a much larger rock volume. A Vertical Seismic Profile (VSP) is the natural bridge between the two data types: its resolving power is intermediate, and it is recorded in time at well-known depths. Thus, it can directly check the conversion between the time domain of surface profiles and the depth domain of well logs.
