Summary:
The need for efficient seismic interference (SI) attenuation solutions is essential to reduce time-sharing that is very costly. We present two SI attenuation methods, both based on the automatic vector field estimation of the SI local moveout. The first method proposes an automatic determination of tau-p mute parameters, while the second one uses line integral convolution and the estimated vector field to separate SI from reflection hyperbolas. Because of the automatic detection of SI attributes, they require little user interaction and the processing time is short. Both methods are tested on real shot gathers and successfully attenuate the SI while preserving the reflections.
