Despite advances in renewable energy, oil and gas remain the world’s primary energy sources. Meanwhile, a large number of oil fields remain untapped after traditional oil production methods. Chemical enhanced oil recovery (EOR) has been evaluated as an effective method for extracting oil from trapped and residual reservoirs. This method relies on the injection of chemical reagents to enhance oil recovery. This article examines the current state of chemical EOR methods, describing the new chemical reagents used and the mechanisms for their application in oil production. The main challenges encountered in the application of traditional chemical methods for enhanced oil recovery are highlighted, and new solutions for overcoming them are proposed. Recent trends in the implementation of nanotechnology and their synergistic impact on the stability and efficiency of enhanced oil recovery are compared. The results of laboratory and field studies are presented. Pore scaling mechanisms in enhanced oil recovery (EOR) are shown to be improved by the implementation of nanotechnology. New effective reagent formulations are analyzed. The use of ionic liquids, nanoparticle-based reagents, and new technologies with alkaline cosolvents and polymers demonstrates significant potential for EOR. The chemical reagents and methods used in EOR are important for sustainable energy production. Taking into account the parameters that determine the kinetics of particle deposition in oil, kinetic equations for the paraffin deposition process are presented. 
A diffusion-transport model and a model that takes into account the rate of paraffin deposition and dissolution are considered. The rate of paraffin deposition under typical oilfield conditions is calculated. The data obtained demonstrate their importance for monitoring and routine cleaning of pipelines.
