Solution of VSP dynamic inversion problem using correlated wave-fields

A possibility of using correlation functions for a VSP reverse dynamic problem solution is discussed.<br>The correlation functions are used when dealing with data obtained during the drilling process. An algorithm<br>for the one-dimensional reverse problem solution is constructed. This algorithm involves autocorrelations of<br>source data. The theoretical basis of the method as well as the result of the numerical experiment is given in<br>this paper.
