“…However, there is a great security risk for accidental oil spills which are extremely hazardous to water during the processes of crude oil extraction, storage and uses [4][5][6]. Unfortunately, the oil leakage accidents not only bring a hugely negative influence to the natural environment, but also have already threatened the survival and development of the human society seriously.…”

“…There are also a lot of researches, through the core experiment, analyzed the actual viscosity and viscosity loss factor of polymer solution in porous media in polymer flooding [6][7]. Although there is the study on surfactant adsorption of chemical flooding [8] and the study on interfacial tension of surfactant [9], but study on changing patterns of interfacial tension and adsorption properties of binary multisystem in porous media is less [10]. This paper designed that by the use of TEXAS-500 spinning drop interfacial tension meter and Brookfield viscometer, we can measured and contrasted interfacial tension, viscosity concentration of binary multisystem at the static condition and after passed through the artificial core of different length, measured and calculated dynamic and static adsorption capacity of the binary multisystem on natural oil sand, and then study the actual changing patterns of physicochemical parameters of binary multisystem in porous media, it provides a reference to binary multisystem performance in the seepage of actual reservoir [11].Another section of your paper All manuscripts must be in English, also the table and figure texts, otherwise we cannot publish your paper.…”

Abstract. The sulfonate Gemini surfactant and hydrophobic associating polymers were prepared with different ratio in multisystem, and we measured viscosity and interfacial tension of the solution before pour it into the core. The multisystem with different ratio was poured into the core, we measured the produced liquid viscosity, interfacial tension, the concentration of polymer and surfactant at core outlet with different injection stage and at different locations after stable, calculated the dynamic adsorption capacity of the binary multisystem, and measured the static adsorption capacity of binary multisystem with different ratio on natural oil sand in Suizhong 36-1 Oilfield. Experimental results show that the stable viscosity of the produced liquid of multisystem increased with increase of polymer concentration, and decreased with the increase of the distance flowed through the core, and these changes concentrated on the first 1/3 of core; the interfacial tension decreased with the increase of mass fraction of surfactant, the stable interfacial tension value after passed through the core was about 7-10 times before solution injected; Multisystem has the chromatographic fractionation in rock.

“…As pressure decreases beyond a specific threshold, the oil will no longer flow automatically from the reservoir. In order to increase pressure in the reservoir, during the secondary phase, gas or water is injected into the reservoir (Park et al 2015). While most crude oil reservoirs are preferably oil-wet, the sweep efficiency associated with water flooding can be limiting which leads to difficulty in recovering crude oil during the secondary phase.…”

“…While most crude oil reservoirs are preferably oil-wet, the sweep efficiency associated with water flooding can be limiting which leads to difficulty in recovering crude oil during the secondary phase. Reports show that only 20-40% of crude oil is recovered with the primary and secondary recovery processes (Park et al 2015;Hu et al 2016a), indicating that more than half of the oil remains trapped in the reservoir. Capillary forces limit the mobility of oil in the reservoir during the primary and secondary recovery processes (Wu et al 2008).…”

“…The wettability of petroleum reservoirs is a key factor in the oil recovery process. Altering the reservoir's wettability from oil-wet to water-wet conditions induces extreme changes in displacement mechanisms (Standnes and Austad 2000a, b;Strand et al 2003Strand et al , 2008Somasundaran and Zhang 2006;Mohan et al 2011;Ravari et al 2011;Tabrizy et al 2011;Wang et al 2011;Park et al 2015). The kinetics of wettability in an oil reservoir are governed by the surface activity of a surfactant, which is initially influenced by solution chemistry (Jadhunandan and Morrow 1995;Strand et al 2008;Karimi et al 2012).…”

Any efficient exploitation of new petroleum reservoirs necessitates developing methods to mobilize the crude oils from such reservoirs. Here silicon dioxide nanoparticles (SiO 2 NPs) were used to improve the efficiency of the chemical-enhanced oil recovery process that uses surfactant flooding. Specifically, SiO 2 NPs (i.e., 0, 0.001, 0.005, 0.01, 0.05, and 0.1 wt%) and Tween Ò 20, a nonionic surfactant, at 0, 0.5, and 2 critical micelle concentration (CMC) were varied to determine their effect on the stability of nanofluids and the interfacial tension (IFT) at the oil-aqueous interface for 5 wt% brine-surfactantSiO 2 nanofluid-oil systems for West Texas Intermediate light crude oil, Prudhoe Bay medium crude oil, and Lloydminster heavy crude oil. Our study demonstrates that SiO 2 NPs may either decrease, increase the IFT of the brinesurfactant-oil systems, or exhibit no effects at all. For the brine-surfactant-oil systems, the constituents of the oil and aqueous substances affected the IFT behavior, with the nanoparticles causing a contrast in IFT trends according to the type of crude oil. For the light oil system (0.5 and 2 CMC Tween threshold concentration resulted in a decrease in IFT, and concentrations above this threshold resulted in an increase in IFT. The IFT decreased until the NP concentration reached a threshold concentration where synergetic effects between nonionic surfactants and SiO 2 NPs are the opposite and result in antagonistic effects. Adsorption of both SiO 2 NPs and surfactants at an interface caused a synergistic effect and an increased reduction in IFT. The effectiveness of the brine-surfactant-SiO 2 nanofluids in decreasing the IFT between the oil-aqueous phase for the three tested crude oils were ranked as follows: (1) Prudhoe Bay [ (2) Lloydminster [ and (3) West Texas Intermediate. The level of asphaltenes and resins in these crude oil samples reflected these rankings. A decrease in the IFT also indicated the potential of the SiO 2 NPs to decrease capillary pressure and induce the movement and recovery of oil in original water-wet reservoirs. Conversely, an increase in IFT indicated the potential of SiO 2 NPs to increase capillary pressure and oil recovery in reservoirs subject to wettability reversal under water-wet conditions. Raspberrylike morphology particles were discovered in 5 wt% brinesurfactant-SiO 2 nanofluid-oil systems. The development of raspberry-like particles material with high surface area, high salt stability, and high capability of interfaces alteration and therefore wettability changes offers a wide range of applications in the fields of applied nanoscience, environmental engineering, and petroleum engineering.
