Abstract
A solution to a forward and an inverse problems for the transient response of coaxial cylindrical media (multistring constructions in boreholes) is based on the spectral approach using the Fourier integral. The inverse problem is solved by calculus of variations. The results of mathematical modeling of the transient process provided a basis for interpretation of real log data.
