Some technological methods used for layer-based velocity-depth model building
Nowadays there are a plenty of methods of velocity-depth model building. However, just a few algorithms are used in practice. In the paper we will show some technological methods of velocity-depth model building, which are more or less universal from the point of view that they may be used in a wide variety of seismic-geological conditions. Their limitation consists in their orientation to layered model, but the extension of a set of layered models lets us consider this limitation has no influence on practical problems solving.
