Application of Two Ground Roll Reduction Techniques to Scattered Ground Roll

IS-3 APPLICATION OF TWO GROUND ROLL REDUCTION TECHNIQUES TO SCATTERED GROUND ROLL JULIEN MEUNIER 1 and MARC BECQUEY 2 1 Summary Scattered noise attenuation is one of the most challenging problems of the land seismic method. Even full fold 3D geometry does not provide an effective solution to this problem. This paper shows how 2 ground roll reduction techniques namely 3D FK filtering and Polarisation filtering designed to attenuate radial noise can be adapted to also reduce scattered noise. Introduction Any ground roll reduction technique must take advantage of the difference between Signal (the reflected waves) and Noise (the ground
