Summary:
This report will analyze methods of near surface anomalies' consideration at the time of depth migration. One of the main troubles with obtaining true location of reflection horizons in depth domain is connected with velocity anomalies in the near surface. Therefore, in our report we will investigate near surface model building with support from seismic data engaging extensive wells' information. Constructed near surface model will be included in generic depth velocity model.
