Abstract:
A method of calculating a throw volume for a seismic data volume, comprising:(a) selecting a range of time shifts, a search direction, a data location separation, and a vertical time window for the seismic data volume; (b) calculating a cross-correlation between data values in the seismic data volume which correspond to first and second data locations separated by the data location separation and symmetrically located in the search direction on each side of a target data location; (c) repeating step (b) throughout the vertical time window for each time shift in the range of time shifts; (d) storing the time shift corresponding to the maximum cross-correlation calculated in steps (b) and (c) in the throw volume; and (e) repeating steps (b), (c) and (d) for a plurality of target data locations in the seismic data volume.
