In this tutorial section, we are going to describe the processing sequence for a 3D land data set. This is quite commonly used processing sequence, so we can design our own processing sequence depending upon the project requirements and you are welcome to make any difference tests and improving the flow. The main goal of current tutorial is to show you how to use g-Platform system, how to create an conventional processing sequence, which is consist of:

1.Create project;

2.Load data and Geometry;

3.Seismic data QC and trace editing;

4.Spherical divergence;

5.Refraction static correction;

6.Surface consistent amplitude corrections (SCAC);

7.Noise attenuation  before deconvolution (spikes, linear, ground-roll);

8.Surface consistent deconvolution;

9.Velocity analysis;

10. Residual static correction;

11. Noise attenuation after deconvolution (linear, random);

12. Multiple attenuation (iteration 1);

13. Regularization and 5D interpolation;

14. Pre-stack time migration (PSTM);

15. Residual moveout corrections (RMO);

16. Multiple attenuation (iteration 2);

17. Stack;

18. Foot prints attenuation;

19. Post-stack processing (additional noise attenuation, spectrum balancing);

20. AVO attributes and angle stacks;

21. Depth migration (PSDM).
