In common depth point seismic exploration, seismic traces are corrected for normal moveout and stacked to form a composite trace. The composite trace is successively time shifted to provide a plurality of reference traces characterized by the normal moveout of the seismic traces. The reference traces are crosscorrelated with the seismic traces, and the resulting correlation functions are utilized to enhance the primary reflection signals of the seismic traces.
