A-09 SUPPRESSION OF POWER LINE INTERFERENCE IN SEISMIC RECORDS F. KIRCHHEIMER WesternGeco P.O. Box 510530 Buchholzer Str. 100 30655 Hannover Germany Abstract 1 Seismic records often contain electromagnetic noise from nearby power lines. An efficient procedure to remove this type of interference is therefore desirable. For everyday use in the preprocessing stage such a process should have no impact on uncontaminated data should not affect the spectra of contaminated data more than necessary and should be able to work with minimal a priori knowledge of the characteristics of the noise. A method is presented that largely meets these requirements. It
