A spectrum of time/depth conversion techniques are presented which, in order of presentation, require greater effort as needed for increasingly complex structure.These techniques are (1) using regionally smoothed stacking velocities, (2) using horizon-keyed interval velocities, (3) using iterative forward ray-trace modeling, and (4) using modeling in conjunction with depth migration. Case histories are presented which illustrate the operation and effect of each of these techniques.
