“…The application of small-molecule compounds to reduce the coagulation and viscosity of waxy crude oils has also been reported in recent years. AlSabagha et al 202 synthesized a new small molecule surfactant type star compound 6,6′-(((phenylmethylene,o-olieat)bis(oxy))bis(ethane-2,1-diyl))bis(2-phenyl-o-olieat-1,3,6-dioxazocane)), the nonpolar part of which can effectively interact with the wax molecule and the amide group of which is able to create polar attraction with asphaltenes, thus improving the wax crystal microstructure (Figure 23). Many authors have reported that asphaltenes are natural pour point depressants, but the pour point and viscosityreducing effect of individual asphaltenes is not uniform.…”

The research on the flowability of waxy oil has spanned more than a century and is still attracting much attention. How to improve the flowability of waxy oil to ensure safe and efficient pipeline transportation and storage is of great practical importance for the industry. In this work, we have systematically reviewed the research advances in improving the flowability of waxy oil. First, the crystallization properties and phase behavior of waxes are described based on their chemical structure, thermodynamic properties, and solution phase properties, with emphasis on the solventized layer properties of wax crystals. Then, the mechanisms, process, and research progress in flow improvement of waxy oil are discussed from three major aspects: process improvement, equipment improvement, and chemical treatment, with emphasis on the summary of waxy oil pour point depressants in recent years. The remaining challenges and perspectives for future research on flow improvement of waxy oil are presented.

This work is aimed at developing methods for increasing the production of heavy crude oil while optimizing energy costs. Various methods have been studied for recovering heavy oil from deep reservoirs. Based on the developed methods, a number of dynamic models have been obtained that describe the behavior of the temperature field in the tubing. Estimations of thermal deformation are carried out. On the basis of dynamic models, fundamentally new devices are obtained and registered in the prescribed manner, providing a subsystem for automated process control systems.
