Abstract

Stacking velocities is input when creating a velocity cube. It is thus of great importance that the quality is good so the use of the velocity cube in depth conversion can be reliable.

One source of error can be missties in stacking velocities; i.e. crossing lines of stacking velocities show different values in the crossing points.

This documentation tells how you can correct missties in stacking velocities so the crossing stacking velocity lines will match.

Example of missties in stacking velocities

The missties can be corrected if the stacking velocities are regular.

Regular stacking velocities

The concept regular stacking velocities means a set of survey lines where all lines hold the same number of vertical values in regular depth or time positions. If not regular, use the command object Make regular stacking velocity to transform the stacking velocity dataset.

Menu for transforming stacking velocities to a regular form.

In many cases the stacking velocities are already in a regular form. But some typical cases where it is not are when two set of stacking velocities from different surveys shall be merged and there are obvious missties. In those cases it it necessary to make all the stacking velocity data regular with the same number of vertical registrations.
