Handling of static corrections in multiple prediction

A method for use in processing seismic data, comprising:

• applying a primary correction to the original seismic dataset to improve the continuity of primary reflections, previously rendered discontinuous by anomalies related to changes in the subsurface over the acquisition time of the survey to yield a continuous dataset;
• predicting the first order multiples using the continuous dataset,
• applying a multiple correction to the seismic data to yield a multiple-corrected dataset;
• taking the difference between the predicted multiples and the multiple-corrected dataset to yield a difference dataset;
• and
• applying the inverse of the multiple correction to the difference dataset.
