“…Meanwhile, around 60% of the OOIP remains trapped in oil reservoirs [1] , [2] , [3] , [4] . Despite the current dire economic situation due to the impact of COVID-19 on energy consumption, the future high demand for energy imposes the need of additional recovery from the remaining crude oil in mature fields, which is targeted by Enhanced Oil Recovery (EOR) techniques [5] , [6] , [7] , [8] , [9] , [10] . The application of surfactants in EOR has been always considered an effective approach for increasing oil recovery.…”

“…35 In addition, recent experiments have confirmed the synergistic effect of electromagnetic waves and dielectric (or magnetic) nanoparticles in improving fluid mobility. 36,37 Dielectric particles can enhance the propagation of electromagnetic waves, and in turn, electromagnetic waves can improve the sweep efficiency by changing the viscosity of dielectric particles and reduce the interfacial tension between nanofluids and crude oil, thus improving the efficiency of oil recovery. However, the current research is limited to the application of low-frequency electric field, ignoring the influence of the electric field on a hydrogen bond network in the formation nanopore when the frequency reaches terahertz level (10 12 Hz).…”

To mitigate high pressure under-injection with the purpose of depressurization and augmented injection in low-permeability reservoirs, an efficient strategy is proposed based on the electric resonance of the hydrogen bond that is induced by an oscillating electric field. We studied the effects of the electric field on water microscopic structures, dynamics properties, flow, and injection in the nanopore composed of two hydrophilic quartz layers using molecular dynamics simulations and density functional theory calculations. The electric resonance generated by the electric field with a frequency of 16,910 GHz induces the breakage of the hydrogen-bonded network to the largest extent, thus greatly improving the movability of water in the nanopore mainly depending on the following mechanisms: (1) the water tetrahedral structure is destroyed, and water molecules in the first coordinate shell decrease; (2) water diffusion is enhanced, the adsorption residence time of water becomes shorter, and the hydrogen bond retaining intact lasts much shorter; and (3) water flow velocity at the nanopore center and surfaces is greatly increased, the slippage length becomes larger, and the apparent viscosity of water is reduced. Consequently, the electric resonance can effectively reduce the pressure and increase the efficiency for water injection development in low-permeability reservoirs.

“…Over the years, enhanced oil recovery (EOR) processes have been developed to recover additional trapped oil from the remaining oil in the developed reservoirs (Yekeen et al 2019). Compared to other EOR techniques, chemical flooding appears to be more effective and economic (Belhaj et al 2019b;Li et al 2019). For a mature water flooding, the capillary number is usually in the range of 10 -7 to 10 -6 , which is considered insufficient to recover a sufficient oil volume; thus, a great deal of residual oil remains behind (Ahmed and Khaled 2018).…”

ASP (Alkaline/Surfactant/Polymer) flooding is one of the most promising techniques that has proven to have successful application in several laboratory and pilot tests. However, the formation of persistent and stable emulsions is one of the associated problems with ASP flooding. The present work investigated the effect of sodium carbonate alkaline, Alpha Olefin Sulfonate (AOS) surfactant, and GLP100 polymer on produced crude oil emulsion. The study was conducted by measuring the emulsion stability in terms of water separation and rag layer volume using a TurbiScan analyzer, the dispersed droplet size using cross-polarization microscopy, the interfacial tension using spinning drop tensiometer, and rheological properties using rheometer. The experimental results have shown that AOS presence increased the emulsion stability only when its concentration is above 100 ppm. Meanwhile, below 100 ppm, the presence of AOS promoted water separation and reduced the rag layer volume. In a less significant manner, a high concentration of sodium carbonate alkali increased the stability of the emulsion. The use of GLP100 Polymer has shown substantial ability in promoting water separation and reducing the rag layer volume to a minimal level. It is believed that the outcomes of this work will aid in developing a suitable destabilization process to enhance the oil–water separation and produced water treatment from ASP flooding in the oil production fields. Further investigations on AS, AP, SP as well as the ASP's combined effect on emulsion stability, droplet size, interfacial tension and rheological properties are highly recommended to support the decision-makers on the EOR implementations with chemical additives.
