Knowledge of the reservoir rock wettability and its influence on petrophysical properties is a key factor to determine the mechanisms and assess the efficiency of oil recovery. In the reservoir rock at the presence of different liquids, it is very important to obtain information about the type of wettability of the rock. Since the understanding of the relationship between wettability and distribution of water and oil in the pore space is necessary to assess the efficiency of oil recovery. Wettability is one of the main parameters that determines the position of the liquid in the reservoir pore space and fluid flow. Wettability affects the properties of petrophysical rock containing hydrocarbons, among others, saturation, capillary pressure, relative permeability, electrical properties of reservoir rocks. Also affects the multiphase flow in porous media. The aim of this article is to characterize the petrophysical parameters of rocks dependent wettability, an overview of the research state of the impact of wettability on the selected petrophysical parameters and presents directions of the future research.
