Clay-carbonate rocks of the Kashiro-Verei age of one of the regions of the Volga-Ural oil and gas region are considered as an object of research. The possibility of studying reservoirs by X-ray tomography of a full-sized and standard core in conjunction with the use of electron microscopy has been scientifically substantiated. As a result of comprehensive studies, lithological types of rocks have been identified that differ in the structure of the capacitive space. The representativeness of various lithotypes in the volume of rocks was quantified based on the data of studies of a full-size core. A joint analysis of the results of standard core tomography and electron microscopy made it possible to examine the structure of the pore space and the development of microfracturing processes at a detailed level. It is concluded that the considered type of development object is characterized by a void space, through which fluid filtration is potentially possible. The conducted studies made it possible to more reliably assess the prospects for the use of enhanced oil recovery methods, primarily hydraulic fracturing technology.
