<p>A technique is provided for processing seismic data to resolve overlapping events within individual traces of a gather of traces. Each of the traces is partitioned into a plurality of overlapping time intervals. The time component of the overlapping time intervals is adjusted relative to a common midpoint. The resulting time adjusted blocks define time-adjusted traces. A mathematical model is designed where the total energy of the time adjusted traces is equated to the total energy of the original traces. However, energy of individual time adjusted time intervals may be varied. Further, corresponding time intervals of different time-adjusted traces are constrained to be similar. The mathematical model may be resolved such that energy associated with separate events at a common temporal location in a non-adjusted trace (e.g., overlapping events within the trace) may be unevenly apportioned into first and second temporally separate locations in a time adjusted trace.</p> |
