Description
Multiple attenuation
This module designed to attenuate the multiple waves. It includes 2 modes of multiples attenuation:
1.Low velocity wave attenuation
2.High velocity wave attenuation
The multiples are searched and attenuated in local windows transformed into FK domain.
Parameters
Number of traces
Number of traces for creation a sliding window. The transformation to FK domain and dip events searching will be performed inside this window. The overlay between windows is 1 trace
Number of samples
Number of samples for creation a sliding window.The transformation to FK domain and dip events searching will be performed inside this window. The overlay between windows is 1 sample
Velocity mode
UP and DOWN. Multiples attenuation mode, UP – high velocities wave attenuation, DOWN – low velocities wave attenuation
Use Removable AGC Filter
Use automatic gain control before searching for waves for attenuation
AGC Window
Automatic gain control window
