Abstract
We introduce a steep-dip time migration algorithm which exploits the strenghts of current time migration algorithms and minimizes their weaknesses. This new time migration scheme uses Stolt and phase-shift migration as a base and finite-difference migration as a residual. The data is first redatumed using a phase-shift operation and then Stolt migrated using a constant velocity over some time interval.
