Abstract:
1. A method of processing seismic data comprising: receiving from a plurality of seismic receivers a gather of a plurality of seismic data traces, wherein each of the seismic data traces is received from a one of the plurality of seismic receivers; using a processor to convolve a composite trace according to a convolution wherein X k (t) denotes the k th trace, n is a natural number, a j denotes a trace specific weighting constant, * denotes the convolution operation, and X k ′(t) denotes the composite trace, and wherein the composite trace for the k th trace is convolved from at least three or portions of three of the plurality of seismic data traces, the at least three of the seismic data traces comprising the k th trace, a first group of adjacent traces located on a first side of the k th trace, the first group of adjacent traces comprising at least the k th +1 trace, and a second group of adjacent traces located on a second side of the k th trace, the second group of adjacent traces comprising at least the k th −1 trace; and picking a travel time of an event in the composite trace.
