Table 3
Summary of the processing steps applied to the zero-offset VSP data.
| Step/purpose | Parameters |
| (1) Time-lapse processing | Enhance sampling rate to 0.1 ms Cross-correlation time-shift | (2) VSP processing | Wavefield separation (9-point median filter) | (3) VSP processing | Trace balance Outside corridor mute (60 ms) | (4) Time-lapse processing | Bandpass filter (10–20–80–100 Hz) Wiener filter |
