Permeability anisotropy significantly affects the fluid displacement efficiency and the choice of measures for well stimulation and methods of enhanced oil recovery. When developing hydrocarbon deposits, it is necessary to know the distribution of permeability in the vertical direction. Vertical permeability is important when substantiating the optimal location and design of wells, planning methods for enhanced oil recovery, etc. Currently commonly used studies are not effective enough or too expensive. The article presents a new methodology that allows building a correlation dependence based on empirical data to determine the vertical anisotropy of the reservoir permeability. The petrophysical properties of more than 300 core samples of terrigenous and carbonate rocks were studied. The experiments included measurements of vertical and horizontal permeability, effective porosity, oil and water saturation. Based on the data obtained, a new and improved correlation has been developed, which allows predicting vertical permeability in order to provide better data for modeling.
