The experimental results of the polar hydrocarbon adsorption in saturated porous media after radio-frequency (RF) electromagnetic (ЕМ) influence and the thermal heating for comparison are presented. Temperature dependences of the extracted volume of hydrocarbons from models are shown. Comparing the obtained data an additional influence of RF ЕМ field on the desorption of asphaltenes from the porous media surface has been found, that leads to an increase of the extraction of hydrocarbons from the models. The thermodynamic substantiation and mathematical modeling of heat and mass transfer in а saturated porous media under RF ЕМ influence are used as the basis of theoretical study. The equation of sorption kinetics based on the Henry's Law including а summand that represents the contribution of thermal and ЕМ fields is to be considered. Researches have discovered that the adsorption process slows down under RF ЕМ field influence, which has а positive effect on the filtration ability of the saturated rock. Investigation of the field influence on the asphaltene adsorption process using atomic force microscopy (AFM) was conducted to identify the mechanism of adsorption and desorption of polar components on the surface of the porous medium under the RF EM field influence.
