This article is devoted to a technique of lithology cube constructing for receiving geologically reliable result of collectors’ distribution under low density of well network, by means of approach that includes complexation of stochastic and deterministic methods. Additionally, in the following work has been explored the technique of constructing of the synthetic 3D cube of facies and in its geometry has been integrated the algorithm of smooth transition to the shale line with the use of a cube under condition of sandiness spreading.
