Interbed Multiples Attenuation using 3D Complex Wavelet Transform

Multiples are challenges for seismic data processing and imaging. Interbed multiples are even much worse challenges for land seismic data. A lot of methods have been developed to attenuate multiples in both data and image domains (Moore, I., and R. Bisley, 2006). Multi-dimensional wavelet transform recently has been applied to seismic data processing such de-spike, linear noise attenuation, de-blending, and signal enhancement ((Yu et al., 2017). We extend three dimensional complex wavelet transform to attenuate multiples including interbed multiples. We first review complex wavelet transform. Then the principle of proposed method is introduced. Next, the proposed method is applied to 3D field data examples.
