SEISMIC DATA PROCESSING. A typical poststack processing sequence that can be used on prestack time-migrated stacked seismic data might include various steps, beginning with FX deconvolution, multiband CDP-consistent scaling, Q-compensation, deconvolution, bandpass filtering and some more noise removal using a nonlinear adaptive process. steps of seismic data processing. 7 0 obj >> Seismic Data Processing uses both the concepts of geometrical optics and the powerful techniques of Fourier Analysis. ~��-��J�Eu�*=�Q6�(�2�]ҜSz��K��u7�z�L#f+��y�W$ �F��a��X6�ٸ�7~ˏ 4��F�k�o��M��W��(ů_?�)w�_�>�U�z�j��J�^�6��k2�R[�rX�T �%u�4r��m��8��6^��1��*�}��\��ź㏽�x��_E��E��O�jN��X��{KCR �o4g�Z�}��WZ��p@��~��T�T�%}��P6^q��]��g�,��#�Yq|y�"4";4"'4"�g��X��k��h��l_�l�n�T ��5��]Qۼ7�9�`o��S_I}9㑈�+"��""cyĩЈ,��e�yl��)�d��Ta��^��{�z�ℤ �=bU��驾Ҹ��vKZߛ�X�=�JR��2Y~|y��#�K��]S�پ��à�f��*m��6�?0:b��LV�T �w�,J��]'Z�N�v��GR�'u��a��O.�'uIX��W�R��;�?�6��%�v�]�g��9�� ,(aC�Wn��>:ud*ST�Yj�3��ԟ�� Seismic Data Analysis: Processing, Inversion, and Interpretation of Seismic Data ozdogan Yilmaz, Steven M.

Steve received many awards and acknowledgments of outstanding performances and merits for the advancement of the seismic science. The choice between digital and analog field recording is discussed in relation to the needs of the seismic process and the quality of the seismic data.Among the mathematical processes discussed are velocity filtering and a number of types of Wiener filtering, including horizontal stacking, deghosting, deconvolution, and multitrace digital filtering.
