Surface consistent statics correction associated with EOM procedure

Xinxiang Li and John C. Bancroft

ABSTRACT

A new method for analyzing surface-consistent statics is presented. The criterion of our method is the power maximization of CSP gathers which is similar to Ronen and Claerbout's stack power maximization method. Our advantages are: (1) applied before NMO; (2) CSP gathers collect contributions from all sources and receivers in the migration aperture, this property solves the coupling problems; and (3) the reference traces constructed from each CSP gather are averaged to get the final reference trace, which will be more stable and may have higher signal to noise ratio. Applications of this method on synthetic data give very good results.

The theory and results given are preliminary work.
