The paper highlights the lithological characteristics of apogranite rocks in the zone of tectonization and generation of hydrocarbons. This work is devoted to the study the reservoir properties of an unconventional oil reservoir. The main goal of the work is to assess and visualize the filtration-capacitive characteristics of apogranite tectonites. Oil saturation (85%) of object is confined to the zone of dynamometamorphic transformation of granite. The main lithotype and reservoir in the oil saturation zone is apagranitic tectonite. By the type of fluid storage capacity the reservoir is fractured-cavernous-porous. The main cavitation is intragranular, confined to altered feldspar grains. In the classification this type of reservoir refers to unconventional metamorphic reservoirs with a complex fluid filtration system. In the volume of a sample-cylinder porosity depends on the number of oil slicks, which are mainly confined to grains of altered feldspars, and permeability depends on on the number and opening of fractures. The maximum porosity values are confined to areas with the maximum intensity of oil saturation glow in ultraviolet light. Maximum values of permeability are observed in the crushing zones. The lowest values of porosity are observed in the zones of mylonitization, where areas with oil saturation are single. In sample-cylinders with permeability of less than 1·10-3 mkm2 oil saturation spots are not connected by conductive fracturing. In sample-cylinders with values greater than 1·10-3 mkm2 permeabitity increases depending on fractures connectivity and opening. In the crushing zone, the permeability values increase by 1-2 orders of magnitude, the porosity values by 1-2 units. The permeability in the sample-cylinders from the monolithic sections of the rock reflects the low productivity of these rocks, confirmed by reservoir testing data.
