Abstract
Coherent noise attenuation is a troublesome problem in many seismic exploration areas. Traditional methods often utilize the differences in frequency, wave number or amplitude to separate signal and coherent noise. However, the application of the traditional methods is limited when the above differences between signal and coherent noise are too small to distinguish. For this reason, we try to seek a new method from the differences in the shape of seismic waves, and introduce the mathematical morphological filtering (MMF) into coherent noise attenuation. The morphological operation is along the trajectory of the coherent noise to implement the MMF. Application of this proposed method on synthetic and field seismic data demonstrates an excellent performance.
