Normal Moveout through Partial Corrections

G023 Z-99 Normal Moveout through partial corrections Introduction 1 In seismic data processing Normal Moveout (NMO) correction is applied to common mid point (CMP) gathers to simulate a zero-offset trace from traces recorded at variable source to receiver offset x. Then properly NMO corrected CMP gathers can be the input for a number of different tasks: AVO analysis residual statics computation and most commonly stacking to produce a seismic image with higher S/N ratio and with attenuated multiple reflections. The NMO correction in exploration seismology is a common practice. The wavelet stretching and the event duplication resulting from this procedure
