Zero moveout (ZMO) stacking

This work describes a simple stacking procedure based on summing the traces of a common shot or common seismic section without the usual normal moveou t (NMO) relative time shifts. We refer to this procedure as zero moveout (Z MO) stacking. A simple horizontal summation with no shift in time results i n a stacked trace that is the one-dimensional seismogram for horizontally l ayered media. We explore the practical implementation of ZMO stacks for sou rce estimation or wavelet extraction in deconvolution and/or identification of source-reflector signatures necessary for performing inversion.
