ABSTRACT

Estimating statics by maximization of stack power presumes that NMO correction has flattened events. For estimating statics prior to NMO correction, or where a sufficiently accurate NMO correction is not available, an alternative is to optimize the power of local slant stacks. Long wavelength statics present a problem, as with other algorithms, but varying the number, size, and overlap of the local slant stacks can help.
