The analysis above appears one dimensional in depth.
Conventional interval velocity estimation builds a velocity-depth model
independently at each lateral location.
Here we have a logical path for combining measurements
from various lateral locations.
We can change the regularization
to something like .Instead of merely minimizing the vertical gradient of velocity
we minimize its spatial gradient.
Luckily we have preconditioning and the helix to speed the solution.
Likewise the construction of the data quality screen would naturally involve the full three-dimensional setting.
