Abstract
In this paper, we consider the heterogeneous structure of carbonate rocks-reservoirs of the middle kazanian age of the Gorsky SVO deposit, tectonically confined to the eastern side of the Melekess Depression, according to paramagnetic marks (PM). The use of the electron paramagnetic resonance (EPR) method for studying carbonate rocks is widespread, as it allows obtaining information about the formation features, heterogeneity of the structure of carbonate rocks, and detailing their structure to solve many problems, including the dismemberment and geological correlation of upper Paleozoic sediments.

Materials and methods
Results of core material bitumen carbonates study of the lowerkazanian stage of the Gorsky Deposit in Tatarstan by electron paramagnetic resonance (EPR).
