“…This allows for a synergistic interaction between the polymer and the nanophase, resulting in a strong interface effect. Numerous studies have focused on the application of copolymer nanocomposites in fracturing turbulence drag reduction in oil and gas field development, and the drag reduction mechanism is as follows: when the material enters the reservoir rock pores, the copolymeric nanocomposite overcomes the repulsion of water molecules in the inner wall, breaking through the hydrated layer and triggering multihydrogen bonding, thereby building a hydrophobic layer and forming a gas–solid composite hydrophobic interface with the gas in the pores, greatly reducing the fluid flow drag. − …”

As the global oil market continues to tighten, there is an increasing focus on enhancing oil recovery. However, enhanced oil recovery technologies require the addition of chemical components such as surfactants, alkalis, and polymers to the oil reservoir. These chemical components change the interface structure and affect fluid flow characteristics and phase interactions through adsorption and other behaviors, thus affecting the production efficiency and energy consumption of oil recovery, gathering, processing, and transportation. Particularly, a stable interface is formed during oil recovery that can sharply increase the difficulty of phase separation during oil gathering and processing, thereby considerably decreasing the separation efficiency. Therefore, it is crucial to understand the effect of the interface structure and behavior on fluid flow characteristics and phase interactions for the advancement of the petroleum industry. Herein, the application and regulation of interfaces in the petroleum industry for fluid flow characteristics and phase interactions are reviewed, approaches for characterizing interface characteristics are critically analyzed and discussed, mechanisms of various factors influencing interface formation and stability through phase interactions are investigated, and methods of interface inhibition and destruction are summarized. Moreover, the latest techniques for applied interface formation in the petroleum industry are discussed, and the challenges and research prospects related to interfaces are summarized, providing references for enriching theoretical research in the field of interfaces within the petroleum industry and efficiently optimizing the production and operation of the petroleum industry.

“…The pipeline transportation of different fluids with DRA was reviewed in detail. [58][59][60][61] However, its applications for similar transportation of viscous crudes like heavy and extra-heavy oil were not focused on earlier. The up-to-date development on the topic is compiled here by critically reviewing the relevant studies.…”

The long‐distance pipeline transportation of heavy crudes demands optimal pumping procedures to abate overhead expenditures in the midstream phase. This can be facilitated by reducing both the oil viscosity and the frictional losses induced by the turbulent flow zone. The dualistic approach of reducing both viscosity and drag requires the optimization of several parameters such as concentrations and types of diluents and additives. This manuscript critically reviews various technologies being undertaken to facilitate the pipeline transportation of heavy crude oils by highlighting the technique of dilution coupled with the addition of drag reducing agents (DRA). DRA such as surfactants, nanoparticles, bio‐additives, polymers, and fibres are blended with the diluted crudes to suppress the proliferation of turbulent eddies which in turn assist in pumping the oil at a higher flow rate under constant pressure conditions. Several investigations have reported that drag reduction is significantly enhanced by varying the molecular structure of the DRA. In addition, an optimum flow rate coupled with a specific surfactant concentration at an ideal temperature can significantly reduce head losses and pumping expenditures. Further research is imperative to study the effect of the polymer structure with respect to the induced shear degradation and dissolution behavior of the crude.

The use of additives, generally called DRAs (Drag Reducing Additives), has been proposed to re-duce the energy consumption in pressurized pipes. Although many research works have been conducted to analyze the effect of these additives, less attention have been devoted to the application of coatings to the pipe wall. This paper demonstrates that the application of a hydrophobic coating to the pipe can lead to a head loss reduction for a transition flow regime with moderate Reynolds number values (Re). For this purpose, an experiment was conducted to compare the performance of both coated and uncoated pipes by measuring the head losses and assessing the Drag Reduction Percentage (%DR) and the pipe friction factor (f). This was done for two Polyvinylchloride (PVC) pipes with different nominal diameters (PVC90 and PVC63). In addition, the flow velocity distribution was also measured in all these tests. The %DR decreased as the Re values increased, with the reduction being notably less pronounced for higher Re values. This could be explained by the fact that a partial slip condition is induced by the hydrophobic product. Its effect is significant for a transition regime where the effect of viscosity is important, but it becomes negligible for increasing levels of turbulence. No significant differences were observed in the flow distribution between coated and uncoated pipes, which seems to indicate that the velocity change could be limited to the near-wall viscous sublayer. The results of this work open an important research line aimed at reducing energy costs and the carbon footprint in pipe fluid distribution systems.
