The results of petrophysical studies on low-porosity Riphean carbonates from one of the hydrocarbon fields situated in the Yurubcheno-Tokhomskaya oil and gas bearing zone (Siberian Platform) are presented here. Complex studies of mineral composition; pore structure using different laboratory methods (thermogravimetric analysis using a Derivatograph apparatus, X-ray structure analysis, NMR, computer tomography, whole core analysis etc.) allowed to reveal particular features of Riphean carbonates that served as a basis for working out the methodology of well log interpretationscheme of researches of reservoir fluids are presented.
