Nonlinear seismic trace interpolation

The nonlinear correlation technique has been used to guide a seismic trace interpolant to fill gaps in seismic surveys, replace noisy traces, and produce evely spaced arrays. Given an initial alignment the correlation aligns corresponding features between adjacent seismic traces and quantifies the traveltime difference between the traces on a point-for-point basis. This information is used to construct synthetic (interpolated) traces, at any arbitrary distance between the correlated traces. The technique is applied to a 48-channel, NMO corrected, CDP gather and to a stacked seismic section to demonstrate its use, sensitivities, and limitations in processing and geological interpretation studies. -from Authors
