NMO Correction of Shallow-Seismic Data

N-27 NMO CORRECTION OF SHALLOW-SEISMIC DATA J. BROUWER V. NIJHOF and J. TEMPELS OYO Center of Applied Geosciences Archimedesbaan 16 3439 ME Nieuwegein The Netherlands Abstract 1 The application of traditional NMO-correction techniques in the processing of shallow-seismic data may result in severe distortion. This distortion is observed as a decrease in frequency content (NMO stretch) or even a total loss of data for steep velocity gradients. It is shown that the observed distortion is introduced by the particular implementation of the traditional NMO correction technique. It is furthermore shown that other techniques that have been proposed in literature suffer
