Interpretation of velocity estimates from coherency inversion

Velocity estimation by coherency inversion provides a velocity-depth macro-model of the subsurface. Uncertainties in the velocity and depth estimates for the model can be calculated using a combination of the response surface technique and the Dix equation. In the layer-stripping strategy, the method takes into account the local errors connected mainly to the current layer and the global errors connected to the derived overburden. -from Authors
