To create effective methods for the interpretation of GIS data in practically monomineral quartz sand and siltstone rocks
of the upper Devonian of the southeast of Tatarstan, it is necessary to take into account the features of the sedimentation
conditions that have determined a noticeable difference in the development of secondary processes and that undoubtedly
affected their capacitive filtration properties. Improved correlation dependencies make it possible to increase the accuracy
of the determination of the coefficients of bulk clayiness and open porosity of reservoir units according to the standard
GIS complex, which is especially important when recalculating balance oil reserves and constructing detailed threedimensional multilevel geological and hydrodynamic models of deposits.
Key words: sandstone; porosity; permeability; data interpretation; sorting; oil saturation.
