1. A method, comprising:
obtaining, by a computer processor, a P-wave velocity model and velocity ratio data regarding a geological region of interest;
generating, by the computer processor and based on the P-wave velocity model and the velocity ratio data, an initial S-wave velocity model regarding the geological region of interest;
determining, by the computer processor, a plurality of velocity boundaries within the initial S-wave velocity model using a trained model;
updating, by the computer processor, the initial S-wave velocity model using the plurality of velocity boundaries, an automatically-selected cross-correlation lag value based on a plurality of seismic migration gathers, and a migration-velocity analysis to produce an updated S-wave velocity model; and
generating, by the computer processor, a combined velocity model for the geological region of interest using the updated S-wave velocity model and the P-wave velocity model.
