Abstract

We present an interferometric interpolation method for filling in trace gaps in common shot gathers. There are two steps for implementation: first, virtual traces are created in the trace gaps by cross-correlation of recorded traces in a shot gather followed by summation of correlated trace pairs over all shot positions; secondly, a 1-D matching filter is applied to the predicted events to correct for the wavelet and amplitude distortions. By using a 1- D assumption (assuming a layered medium around the midpoint in a common midpoint gather), the interferometric interpolation method can be applied to common midpoint gathers.
