Examples of the velocity uncertainty estimation using CRP gathers. Each panel shows the CRP gather after PSDM using the velocity model with 5% step change (70% to 130% of original velocity model as shown above each gather). (a) CRP gather at CDP 8140. The target horizon is located at approximately 7,800 m in the CRP gather migrated with 100% velocity model. (b) CRP gather at CDP 6705. The target horizon is located at approximately 8,300 m in the CRP gather migrated with 100% velocity model.
