The article is focused on the process of geological modeling of the complex geological structure in consideration of the analysis of uncertain background data. The territory is understudied. For this reason model was developed using derived dependence of structure variability on remoteness of wells with actual information and formation depth. To present layer variability when constructing lithology cube, combination of deterministic and stochastic methods by applying geological-statistical profiles was used. While making distribution of characteristics in interwell space declustering of initial data was exercised. The model of relative permeability to phase and capillary model were built on the basis of examined well logging data. The methodology for interactive petrophysical modeling of undersaturated reservoirs in the transition zone was tested and applied.
