Ultra-high molecular weight poly--olefins are widely used as drag reducing agents (DRAs) for pipeline transportation of oil and refined petroleum products. The synthesis of polyolefin DRAs is based on low-temperature ZieglerNatta (ZN) polymerization…
Recently, global attraction has shifted toward heavy unconventional crude oil due to the depletion of light oil resources. Generally, heavy crude oils are highly viscous in nature
This article provides a method to design a viscosity reducing agent, which builds a crude oil model through molecular simulation and calculates the type of monomer suitable for the viscosity reduction of the crude oil. Viscosity reducing agent was…
In oil-displacement processes, a compound surfactant system is used to reduce the crude oilwater interfacial tension (IFT) via the synergistic effect of multiple surfactants. To the best of our knowledge, however, since there is no systematic…
