A method for picking seismic stacking velocity based on structures in a subterranean formation, the method comprising:
- receiving seismic data representing a subterranean formation;
- generating semblance spectrums from the seismic data representing the subterranean formation;
- smoothing the semblance spectrums;
- and
- picking stacking velocities based on the smoothed semblance spectrums.
A system for picking seismic stacking velocity based on structures in a subterranean formation, the system comprising:
- a stacking velocity picking engine comprising:
- a semblance generation module operable to generates semblance spectrums from the seismic data representing the subterranean formation;
- a structural oriented smoothing module operable to smooths semblance spectrums based on structures in the subterranean formation;
- and
- a velocity-picking module operable to picks stacking velocities based on the smoothed semblance spectrums.
