Up: Cole: Statics estimation by
Previous: REAL DATA EXAMPLE
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.
