“…McMillan et al [23] performed core flood experiments on crude oil samples with different resin and asphaltene concentrations and determined factors controlling the rock wettability during low-salinity water injection. Fu et al [24] studied the mechanisms of an organic alkali-surfactant-polymer flooding system. They demonstrated that the oil recovery was increased by about 20 %, and that the recovery increases with higher organic alkali concentration.…”

The elution of high-viscosity substances from a granular bed using fluids with different interfacial tensions was investigated. Analyses of changes in flow resistance and the degree of saturation of the deposit during the process were conducted. The elution process was described by means of the modified concept of capillary bundles, based on the Blake-Kozeny-Carman relationship. The use of this dependence can be helpful in determining the degree of saturation of the deposit at any given time of elution process only on the basis of the flow hydrodynamics and parameters of the deposit and liquid. This makes it possible to estimate the residual saturation of the bed without the need to perform troublesome experimental research for the content of oil in the reservoir.

“…Although ASP flooding has been proven to be an effective method for enhancing oil recovery and has been fruitful in actual oil fields [25][26][27], due to the late birth of this technique, its enhanced recovery mechanism and characteristics, especially the evolution of pressure field, remain to be explored. Physical experiments [27][28][29] and numerical simulation [30][31][32][33][34] about ASP have been conducted in recent years. Li et al [35] studied performance of ASP systems and effects of the individual component.…”

ASP (alkali-surfactant-polymer) is acknowledged as an effective technology to improve the oil recovery. The microscopic displacement efficiency and macroscopic sweep efficiency have been discussed in detail for the past few years. However, development performance, especially pressure characteristics, needs to be further studied. This paper aims to explore the pressure evolution performance during ASP flooding, of which the results will shed light on development characteristics of ASP flooding. The study on ASP flooding pressure field development is conducted by laboratory and numerical methodology. A large sandpack laboratory model with vertical heterogeneous layers is used to monitor pressure performance during the ASP flooding. With the help of interpolation methods, a precise and intuitive pressure field is obtained based on pressure data acquired by limited measurement points. Results show that the average formation pressure and its location are changing all the time in the whole process. In addition, the influence of heterogeneity and viscosity on recovery and pressure is also probed in this paper. We built a numerical simulation model to match the experiment data considering the physical and chemical alternation in ASP flooding. Also, response surface methodology (RSM) is adopted to obtain the formula between pressure functions and influencing factors.

“…Compared to other NP, titanium dioxide (nano‐TiO 2 ) is cheap, harmless, thermally stable, and commercially available, which make it a vital representative in the applications in oilfields (Ehtesabi and Ahadian, , ). Despite the excellent enhanced oil recovery (EOR) performance resulting from the synergistic effects of titanium dioxide NP and surfactants(Loosli and Stoll, ), the suspensions of the mixtures are unable to maintain long‐term stability because of the strong tendency of aggregation caused by the high surface area (Gao and Yu, ; Nesterenko and Drelich, ; Oskarsson and Frankenberg, ) and high polarity (Fu and Zhang, ) of TiO 2 . When it comes to oil reservoirs, agglomerated TiO 2 NP would result in plugging issues in the small pores of low‐permeable layers, which substantially hampers the recovery of oil.…”

For improving the oil recovery performance, Ag‐TiO2 nanoparticles (NP) were added to the eco‐friendly sugar‐based anionic nonionic surfactant (GDA) solution, and the mixtures acted as the oil displacement agent. The synthesized GDA and Ag‐TiO2 were characterized using Fourier transform infrared spectrometry (FT‐IR), 1H nuclear magnetic resonance (1H NMR), and X‐ray diffraction (XRD). Changes in the zeta potential and transmission electron microscope (TEM) images of the mixtures confirmed their synergistic effects on the suspension stability. The relationships between surface tension, interfacial tension (IFT), three‐phase contact angle, and emulsion and oil recovery efficiency were comprehensively investigated, both before and after Ag‐TiO2 NP addition. We concluded that the Ag‐TiO2/GDA mixtures could effectively alter the contact angle, decrease IFT, and form stable emulsions, thereby resulting in the enhancement of oil recovery. The core flooding conducted with the stabilized NP‐surfactant (Ag‐TiO2 and GDA) fluid showed a marked improvement in oil recovery over 18%. This study provides additional options for using the synergistic effect of NP and surfactants for enhanced oil recovery.
