Conclusions

Optimizing local slant stacks offers a way to estimate statics without having to moveout-correct the data. Like other statics techniques, it has difficulty handling long-wavelength statics. Careful selection of the number, size, and amount of overlap between local slant stacks appears to improve the ability of the method to deal with long-wavelength terms, but more experience is needed. Beam stacks may be a useful addition to the method.
