“…8) was the best prototype and retained 60 % of its viscosity after 28 days, compared to an AMPS-type terpolymer, which retained 10 % of the viscosity. Numerical and experimental data of the polymer reduced viscosity in brine were determined, and simulation for salinity resistance prediction of cationic terpolymers at high temperatures was estimated [197]. Molecular dynamic simulation indicated that, in general, increasing the length of the side alkyl chain in imidazolium-derived terpolymers leads to a decrease in affinity to aqueous media [198].…”

A bibliographic review of research works dealing with gels based on synthetic polymers and their application in water control under harsh conditions was compiled. The extreme conditions were defined to be above 100 °C with 100 000 ppm of total dissolved solids, including divalent ions. Works describing laboratory experiments and oilfield implementations were also considered. According to current literature, some gels based on synthetic polymers have displayed desirable properties for water control, but in many cases, research is still at laboratory level. Therefore, further studies are required to understand the mode of action and stability of gels and polymers submitted to hard conditions in order to produce high‐performance prototypes.

Temperature and chain length play significant roles in determining the physical properties of polymer melts. In the current computational research, a molecular dynamics (MD) approach was implemented to describe the static and dynamic properties of (1) high-density polyethylene-1-butene with 120 beads in backbone (PE120) and (2) entangled high-density polyethylene-1-butene with 600 beads in the backbone (PE600). The transferable potentials for phase equilibria force fields were used for CH2 beads in a defined initial condition. First, the equilibrium phase of the designed systems was reported with total energy and density convergency at various initial temperatures (T 0 = 450, 470, and 490 K). Also, gyration radius (R g) and end-to-end distance (R) were calculated for the static behavior description of the two PEs. Zero-shear viscosity (η 0), mean square displacement, and diffusion coefficient (D) were estimated to define the dynamic behavior of PE120 and PE600 systems. MD outputs predicted that 10 ns is sufficient for equilibrium phase detection inside polymeric samples. After equilibrium phase detection, R g converged to 14.97 and 17.35 Å in PE120 and PE600, respectively (T 0 = 450 K). Furthermore, MD outputs show that temperature variation can considerably affect the time evolution of the system. Numerically, the η 0 of PE120 and PE600 converged to 49 and 168 cp at 450 K. These results of η 0 parameter as a function of temperature are an important output of MD simulations. The results predicted that η 0 decreases to 24 and 44 cp for PE120 and PE600 samples with an increase in temperature from 450 to 490 K. With the creation of the entanglements network, D reached the highest value of 2 × 10−9 m2·s−1 among the designed polymeric systems. The results are in good consistency with experimental reports. It is expected that the result of this study can be used in designing improved polymeric systems for real applications.

Applications of Ionic Liquids in the Oil Industry: Towards a Sustainable Industry

The application of chemical products, particularly polymeric products, is undoubtedly one of the most helpful and effective alternatives for EOR processes and changes in oil mobility. Appropriate chemical products provide more favorable interfacial conditions to the flow of petroleum, reducing the interfacial tensions between water and oil, and therefore, increasing the miscibility of these two compounds, and allowing the oil to flow in the porous medium. In this context, ionic compounds and particularly ILs are proving to be important auxiliaries in the performance of chemicals used for this application, particularly in extreme conditions of temperature and salinity.
