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.

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.

Adjusting missties in stacking velocities

Activate the command object Adjust stacking velocity lines found under the entry Regular Stacking Velocities.

It is also possible to have a weigth factor when doing correction. It should be applied if the adjustment has to be performed on both crossing sections, f.inst. 0.7 on one and then no adjustment using the other as input.

Options in misstie corrections

There are other features and options within the misstie correction concept. Especially if one wants to regulate the stacking velocties for a section within a vertical area described with a digitized boundary. In that case read the article Working with regular stacking velocities.
