SEISMIC   PROCESSING   2D   MARINE

Production seismic processing sequence for 2D marine project usually consists of the following steps:

1.Create project;

2.Load input data;

3.Geometry apply and quality control;

4.Trace editing;

5.Receiver motion correction;

6.Water bottom double travel time of  to trace headers;

7.Tidal static corrections;

8.Low frequency filter;

9.Spherical divergence;

10. Direct wave and coherent noise attenuation;

11. Swell noise attenuation;

12. De-bubbling;

13. Zero-phase correction;

14. De-ghosting;

15. Multiple attenuation (SRME);

16. Amplitude correction;

17. Residual random and coherent noise attenuation;

18. Velocity analysis;

19. Residual multiple attenuation (RADON);

20. Residual diffraction mutiples and linear noise attenuation;

21. Pre-stack time migration (PSTM);

22. Multiple attenuation (iteration 2);

23. Residual moveout corrections (high order);

24. Residual time-phase corrections;

25. Stack;

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

27. AVO attributes and angle stacks.
