1. A method, comprising: obtaining an isotropic velocity volume for a geophysical volume; obtaining an isotropic depth image of the geophysical volume; obtaining time-depth pairs at downhole locations in the geophysical volume; generating mis-tie values based on the time-depth pairs and the isotropic velocity volume; assigning uncertainties to the mis-tie values; and generating a mis-tie volume that satisfies a target goodness of fit with the mis-tie values.
