A method for calculating time-strains for two seismic data sets resulting from seismic exploration of the same subsurface structure uses selected subsets of data from the two seismic data sets to calculate time-shifts for each trace. A smooth function is fitted along each trace based on the calculated time-shifts a time derivative is applied to the smooth function to obtain time-strains along each trace. Figure 4 Start Pairing traces included in the two seismic data sets and corresponding to a substantially same location of the explored underground structure Selecting subsets of data from each trace of a pair of traces to obtain a pair of thinned traces Calculating time-shifts for the pair of thinned traces to evaluate substantive differences between the two data sets Stop |
