The resulting stack is a model that best fits the data using additional constraints imposed by shaping regularization. We introduce a recursive stacking scheme using plane-wave construction in the backward operator of shaping regularization to achieve a higher resolution stack. The advantage of using recursive stacking along local slopes in the application to NMO and stack is that it avoids \u201cstretching effects&#8221; caused by NMO correction and is insensitive to non-hyperbolic moveout in the data. Numerical tests demonstrate the algorithm&#8217;s ability to attain a higher frequency stack with a denser temporal sampling interval compared to those of the conventional stack and to minimize stretching effects caused by NMO correction. We apply this method to a 2-D field dataset from the North Sea and achieve noticeable resolution improvements in the stacked section compared with that of conventional NMO and stack.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>An old paper is added to the collection of reproducible documents: High-resolution recursive stacking using plane-wave construction We propose an approach to normal moveout (NMO) stacking, which eliminates the effects of \u201cNMO stretch&#8221; and restores a wider frequency band by replacing conventional stacking with a regularized inversion to zero offset.
