Right-Hand Rule 3C VSP Wavefield Separation Method

Wavefield separation is one critical step in the three-component (3C) vertical seismic profiling (VSP) data processing. The conventional 3C VSP wavefield separation method exhibits low precision polarization angle and cannot obtain desirable results. This letter proposed the right-hand rule 3C VSP wavefield separation method which has many advantages over the conventional 3C VSP wavefield separation method-particularly the polarization angle precision and wavefields continuity. Analysis of real 3C VSP data demonstrates that the right-hand rule 3C VSP wavefield separation method can enhance polarization angle precision and show a very desirable ability to produce high-continuity wavefields.
