Abstract: VSP data can act as medium of synthesizing drilling data and seismic profile. Composite seismogram can only be used as reference. Hence, to understand the record mode, datum-level selection, weathering and sub-weathering correction method and data processing of VSP data and seismic profile are prerequisites for well utilizing VSP data and horizon calibrations.

Key words: VSP corridor stack, horizon calibration, weathering and sub-weathering correction, synthetic seismogram, average speed, stacking speed, datum level
