N2  - A method is presented for estimating residual statics that are computed prior to normal moveout correction. No velocity information is required, and the offset and structure terms are eliminated from the decomposition. Model source (shot) records are formed using the EOM method of prestack migration to provide a one-to-one trace for cross-correlation. After cross-correlation, the estimated time shifts are decomposed directly into source and receiver statics. The method is stable for ling time windows that are input to the cross-correlation, and provides solutions for structured data where other methods fail.
