To achieve a satisfactory depth conversion apply a smooth velocity field or a smooth velocity cube. It is assumed that the velocity data is covering the seismic outline. If not, the depth conversion will use the nearest velocity data that is covered by the outline.
The generation of a time-velocity cube and trimming towards check shot wells is described in Cube gridding from stacking velocities.
Output
A new outline is generated after depth conversion for each seismic line. The new outline makes a rectangular frame from top to the specified depth. The seismic lines are depth converted following these principles:
