“…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.

Under the guidance of the carbon peaking and carbon neutrality strategies, the recovery, emission reduction, and effective utilization of industrial CO 2 are particularly important. Supercritical CO 2 viscosity reduction technology effectively improves the flowability and reduces the energy consumption of heavy oil pipeline transportation. This work reviews the experimental research on supercritical CO 2 viscosity reductions of heavy oil, summarizes the viscosity reduction mechanisms and main influencing factors, describes the research achievements regarding theoretical parameters such as the solubility and viscosity of supercritical CO 2 and the density and viscosity of live oil, introduces engineering applications of supercritical CO 2 in the oil and gas field, analyses the problems involved in corrosion, stability, and solids deposition of crude oil containing dissolved CO 2 , and presents the current challenges and perspectives. The main future research directions of this technology involve the mechanism of supercritical CO 2 viscosity reduction, ensuring the stability of supercritical CO 2 and crude oil mixtures during pipeline transportation, designing and establishing oilfield surface engineering facilities for supercritical CO 2 viscosity reduction technology, and improving the protection strategies for CO 2 corrosion. This work can provide a reference for the application of supercritical CO 2 in heavy oil development and pipeline transportation.

Resin molecules play a crucial role in the stability of colloidal asphaltene particles in petroleum reservoirs. De-stabilization of the asphaltene/resin interaction due to changes in thermodynamic parameters can cause asphaltene precipitation, thus leading to petroleum field problems such as decreased in situ permeability, as well as severe plugging problems in production facilities. One remedial technology used in the oil industry involves developing synthetic resins with enhanced chemical potential to increase the stability of asphaltene in the oil phase. However, accurately predicting what synthetic resin structures are compatible with asphaltenes in this context can be difficult and ineffective. Here, we introduce a method that enhances the stability of colloidal asphaltene in petroleum fluid by increasing the concentrations of natural-state oil resins and increases reservoir oil recovery by increasing the oil’s aromatic power solvency. The stability of colloidal asphaltene and improvements in oil reservoir recovery were investigated by using an oil prefractionation process and a solvent deasphalting technology based on the residuum oil supercritical extraction process to develop three types of deasphalted oils derived from Kuwait Marrat oil. Using these methods, we found that resin concentration by volume in Marrat oil increased with the removal of more oil fractions. Asphaltene stability in the oil phase was strongly influenced by resin concentration. The deasphalted oils’ aromatic power solvency increased the oil reservoir permeability by twofold. No formation damage was observed for all DAO products in core flooding tests.
