Processing, Inversion and Imaging of Seismic Marine Data of Basin of Jequitinhonha
This work is focused on processing, and imaging of the selected L2140266 line of the Jequitinhonha Basin, Bahia, based on the NMO and CRS stacking methodologies and the Inversion of the NIP wave, where the of post-stacking Kirchhoff migration in time is in depth, and common to all techniques. Beyond in addition, the partial-CRS stack was applied to densification of CMPs. Several tests were performed to optimize parameters, operator openings, minimize the objective function and regularize the parameters of the model, and as a result the flowchart of generated better visual quality of the sections, the main results compared in the course of the work for both methodologies.
