We have extensive experience with challenging noise contamination and maintain the relative amplitudes of the data for further AVO work. We use techniques such as our Genetic Statics algorithm and our unique and innovative Noise Attenuation programs to enhance data in structurally complex areas. It is important to correct for anisotropy during the velocity analysis. These anisotropy values will later be used in the PSTM, extending the maximum usable offsets for better imaging. The velocities are re-picked after the PSTM as data in highly structured areas will change after PSTM. We then re-run the PSTM with the new velocities, and iterate the residual velocity analysis.
