ABSTRACT OF THE INVENTION The present invention relates generally to meth- ods of enhancing seismic data and, more particularly, to methods of attenuating noise in seismic signals. The seismic data are sorted into gathers of seismic signals, and selected coherent events in each gather of seismic signals are aligned. The gathers of seismic signals are then processed so as to transform the balance of the coherent events in each gather of seismic signals into incoherent events. A two-dimensional filter is then applied to the transformed signals to attenuate incoherent events.
