recovery values [6]. The problem is aggravated in tight carbonate rocks, i.e., having matrix permeability less than 0.1 mD [7], as oil flow constrictions become more pronounced. These constrictions are narrow pore throats [8] and the oil-wetness of pore walls. Pore size distribution is difficult to change; however, the wettability state of the carbonate rock can be controlled. Bare carbonate rock is considered hydrophilic; however, its surface, which has been in contact with crude oil for millions of years, has changed its state towards hydrophobic or intermediate-wet. The surface alteration mechanism is very complex and includes several fluid-rock interaction types: polar interactions, surface precipitation, acid-base interactions, and ion binding [9]. The presence, content, and chemical nature of oil polar constituents, such as asphaltenes, resins, and naphthenic acids, as well as the brine salinity and ionic composition [10; 11] determine the wettability state of the rock. Carbonate rock adsorbs the highest amount of asphaltenes [12; 13]. The reason for such a high activity is the presence of weakly basic Ca-OH groups, which dissociate in water and react with polar groups of asphaltenes [14]. The presence of water film, which can always be found in the reservoir, enhances adsorption of polar compounds on the carbonate, as opposed to silicates [15]. First-principles and molecular dynamics calculations also demonstrate the role of asphaltene-resin and asphaltene-asphaltene clustering on the carbonate's surface [16; 17]. All these phenomena lead to the hydrophobicity of carbonate rocks [18] which results in some negative consequences. Hydrophobicity of the rock's surface leads to the oil sticking to the pore walls and corners. Heterogeneous small-radius pores, which are typical for carbonate's matrix, retain oil.
