Prestack 3-D TAU Migration and Velocity Analysis – Application to Seismic Data from Offshore Abu Dhabi

E015 Prestack 3-D TAU Migration and Velocity Analysis: Application to seismic data from Offshore Abu Dhabi Summary 1 We managed to apply a prestack 3-D τ� (a depth variant)� migration on a 3D seismic test data set from offshore Abu Dhabi using the final developed interval velocity model. The velocity model was built through an initial series of 2-D TAU migration velocity analysis and supplemented by 3-D subset migration. A 3-D TAU migration velocity analysis was used to apply the final two updates to the model. The final interval velocity model provided low residuals in common-image gathers and agreed well
