1)Near Surface Diving-wave Tomography

- Make the full use of micro-logs etc. information to set up the initial near-surface Q-field;

- Derive attenuation Q factor from the seismic data;

- Update the near-surface Q field with the near-surface velocity from diving-wave tomography


- Compensate the Q attenuation along the ray-path to improve the imaging resolution and broaden the frequency band;

- Upgrade the data quality of far offset and recover the real subsurface AVO response
