Normal moveout (NMO) correction stretches seismic reflection events at non-zero and far offsets due to the sample-by-sample time-shifting process, prompting various methodological workarounds to mitigate resolution loss and distortion.
Multiple retrieved papers explicitly confirm that conventional normal moveout (NMO) correction introduces stretching artifacts at non-zero or far offsets, degrading temporal resolution and wavelet properties. No papers refute this well-established seismic processing phenomenon; instead, several papers propose new algorithms specifically designed to correct or bypass this stretching effect.
