ABSTRACT:
Method of restoring null traces in seismic records. A trace for which restoration of the data is desired, as well as adjoining traces on each side of the null trace are selected. A series of cross-correlations are determined for all points on the selected trace. Restoration of the data points is conducted by transforming the series of points of the adjacent traces corresponding to the maximum cross-correlation for the point into a Fourier representation, zero-padding the Fourier representation and producing a restored data point from the zero-padded data representation. The procedure is repeated for each point along the trace being restored. This procedure interpolates a trace between two original traces without altering the original data.
