This video contains a basic to advance understanding of Velocity and calculating velocity during NMO correction to best stack the data.


The aim of the velocity analysis is to find the velocity, that flattens a reflection hyperbola, which returns the best result when stacking is applied. This velocity is not always the real RMS velocity.

Therefore, a distinction is made between:
• vstack: the velocity that returns the best stacking result.
• vrms: the actual RMS-velocity of a layer.

For a horizontal layer and small offsets, both velocities are similar. When the reflectors are dipping then Vstack is not equal to the actual velocity but equal to the velocity that results in a similar reflection hyperbola
