## ABSTRACTMy velocity estimation from beam-stacked data successfully reconstructs a velocity anomaly from a field data set. Using the estimated velocity model for depth migrating the data corrects the effects of the anomaly on the positioning and focusing of the reflectors. The estimated anomaly well explains the perturbations in the beam-stacked data caused by the actual velocity anomaly. An analysis of the transformed data also shows that the resolution of beam stacks is sufficient for measuring different effects of the velocity anomaly on the moveouts of the reflections at different offsets. |
