The value of the work lies in the developed methodology for predicting zones with improved reservoir properties of the VK1 formation within the Kamenny (western part) license area of the Krasnoleninskoye oil and gas condensate field. The development of this area is complicated by the presence of extensive oil-water zones, low oil saturation, average reservoir properties, as well as high heterogeneity of the reservoir, the presence of an incised valley and tectonic disturbances. Thus, the forecasting of promising areas is of great practical importance, since the economic efficiency of the well stock, the drilling of wells along the reservoir, the change in drilling goals, the planning and success of geological
and technical measures depend on the prediction.

Materials and methods
Materials: the initial GIS and RIGIS data for 156 production wells were used as input data, surface characteristics of parameters calculated from amplitude cubes in two processing variants involving sedimentological description of the core of 11 exploration wells. Methods: complex analysis of geological and geophysical information, dynamic analysis, construction of spectral decomposition maps, sedimentological description of the core with analysis of sedimentation conditions, search and selection of quantitative criteria for identifying
promising zones.
